Four New dsPIC 16-bit Digital Signal Controllers
A new agreement between ARM and Actel marks
the first time that an ARM processor has been licensed to a programmable logic
vendor for implementation of a soft IP core. This will make the 32-bit ARM7
Thumb family microprocessor technology available to developers who previously
could not afford to use ARM processors. Programmable logic users will have
access to ASIC-like design flexibility with broad third-party support and trusted
IP, as well as the added programmability and security benefits of Actel FPGAs.
As part of the agreement, Actel will develop
a family of ARM technology-enabled FPGA products. The initial devices will be
introduced this year. The soft core ARM7 family processor will be delivered to
customers using the unique security features of Actel FPGA devices. The Actel
Libero and ARM RealView tools will provide an end-to-end integrated solution.
Five New High-Performance, Low-Power 8-bit AVR Flash Microcontrollers
Five new high-performance, low-power AVR Flash microcontrollers
have been announced, aimed at applications requiring a large code space and
extensive interfacing capability.
The devices will feature 64 to 256 Kbytes of Flash program memory and 8 Kbytes
of on-chip RAM. With their linear address range of up to 8 Megabytes, these AVR
devices can handle this amount of memory with no paging.
The new family significantly reduces complete system chip-count requirements.
The integrated 8 MHz RC oscillator can be calibrated to an accuracy of +/-2%,
thus eliminating the need for an external crystal in many applications. A
watchdog timer running from an independent RC oscillator, and a brown-out
detector with programmable detection level is also included. They will operate
at 1.8 volts and feature a variety of low-power modes, including 100 nA
The 100-pin versions will include 4 UART channels, 16 Analog-to-Digital
Converter channels and 16 Pulse Width Modulation channels. The 64-pin devices
will integrate 2 UART channels, 8 Analog-to-Digital Converter channels and 10
PWM channels. The devices will have a maximum performance of 16 MIPS at 16 MHz.
The ATmega640, ATmega1280 and ATmega2560 will come in a 100-pin TQFP housing,
with the ATmega640 also available in 64 TQFP. The ATmega1281 and ATmega2561 will
come in 64-pin TQFP or MLF.
ATmega2561 and ATmega2560 samples are available now. Production will start in
3Q05. ATmega640, ATmega1280 and ATmega1281 will be sampled in 2Q05 with volume
production in 4Q05. Pricing for 10,000 units starts at $4.75 for the ATmega640,
$6.00 for the ATmega1281, $6.40 for the ATmega1280, $7.50 for the ATmega2561 and
$7.80 for the ATmega2560.
Atmel: New Single-Cycle 8051 Core
The new AT89LP family is based on a Single-Cycle 8051 core,
capable of operating at up to 12 times faster than the standard 8051 core.
Operating voltage range is from 2.0V to 5.5V.
The AT89LP CPU requires only one clock cycle for every byte fetch, whereas the
classic 8051 CPU requires 12 clock cycles for every byte fetch. The AT89LP core
is capable of 20 MIPS throughput at 20 MHz clock frequency, compared to the
classic 8051 architecture performing under 2 MIPS at 20 MHz. Conversely, at the
same MIPS throughput as the classic 8051, the new AT89LP core runs at a much
lower clock frequency, thereby reducing power consumption by 85%.
This new family of devices offers designers the opportunity to achieve higher
speed or significantly reduce power consumption, while maintaining software and
hardware compatibility. They can also help designers to solve EMC issues by
reducing operating frequency.
The AT89LP family consists of devices with 2 to 64 Kbytes of in-system
programmable Flash memory, and will be available in a variety of pin options,
from 14, 20, 28 and 44. They include on-chip DataFlash, 10-bit ADC, analog
comparator, pulse width modulators, programmable watchdog timer, enhanced UART,
internal RC oscillator, and functions ideally suited for power management, motor
control and industrial control applications.
The first two devices of the family are the AT89LP2052 and AT89LP4052. Housed in
20-pin PDIP, TSSOP, or SOIC packages, they feature 2 Kbytes and 4 Kbytes of
Flash code memory, respectively. They are pin-compatible with the existing
AT89C2051 and AT89C4051. Samples are available now with production in 2Q05.
Pricing for 10,000 units is $0.85 for the AT89LP2052 and $0.99 for the
Fujitsu has introduced a new family of
microcontrollers developed for network-enabled household appliances, including
the industry's first 32-bit MCUs that incorporate a full range of networking
security features, on-board ROM and RAM, and support for IPv6, the
next-generation Internet protocol.
At the top of the MB9140x series is the MB91403, which supports IPv6 and
includes encryption circuitry supporting the Advanced Encryption Standard (AES),
Data Encryption Standard (DES), 3DES, and other established cryptographic
systems. These encryption circuits are 150 to 200 times faster than
software-based encryption, and are complemented by authentication circuitry. The
series also supports the MD5 and SHAR1 authentication standards, key exchange
methods DH 1/DH 2, and the Internet Key Exchange (IKE) protocol with hardware
The series also includes the MB91401, a 32-bit network system MCU that supports
IPv6, and the MB91402, which is available for customers whose designs do not
require security features. All the new MCUs can operate as standalone systems or
as companion chips for existing designs.
Each of the new system-on-chip MCUs is designed to simplify development of
IPv6-capable products for ubiquitous-computing environments. They incorporate 8
KB of high-speed data RAM, 4 KB instruction cache, along with 256 KB ROM and 64
KB RAM. If more RAM is needed, SDRAMs can be added externally in applications
where the device can serve as a buffer for a high-data-traffic application, or
to cache data that is transmitted over the network. Each device incorporates all
the basic functions needed to serve as a controller for an appliance, including
a 32-bit RISC CPU, an FR core, timer, interrupt controller and UART.
The MB91401, MB91402 and MB91403 come in 144-pin LQFPs. Pricing for the MB91401
begins at $15.78, for the MB91402 at $9.92, and for the MB91403 at $12.86 each
in 1,000-unit quantities.
This new family of application-specific 16-bit
microcontrollers includes a feature set and peripheral functions optimized for
such industrial control applications as robotics, networked systems and
electrical drive systems. These include on-chip A/D converters or CAN
interfaces, and either 64 Kbytes or 128 Kbytes Flash memory. Smart peripheral
functions, such as capture/compare, CAN controller and MAC units, offload tasks
from the core processor and free up compute cycles. Additionally, the MCU bus
structure allows concurrent operation of several chip subsystems, contributing
to a 2x improvement in performance.
The XC164 family achieves up to 40 MIPS with clock speeds of 20 MHz or 40 MHz.
There are three subsets. In addition to the motor-control-specific features in
the basic XC164N subset, the XC164S has a 10-bit A/D converter with 14
multiplexed input channels to support fast, parallel data acquisition. The
XC164D features an integrated TwinCAN module that handles the completely
autonomous transmission and reception of CAN frames in accordance with the CAN
specification V2.0 part B (active).
The architecture includes a 5-stage execution pipeline with 2-stage instruction
fetch, a 16-bit ALU, a 32-bit/40-bit MAC and a register file providing three
register banks. Capture/compare units support generation and control of timing
sequences on up to 32 channels. The entire family is pin compatible in a 100-pin
Like all XC16x MCUs, the new family incorporates On-Chip Debug System
capability. Additional standard features include an interrupt control unit and
an on-chip PLL as part of the clock-generation circuitry.
The first product of the new XC800 family of
8-bit 8051 core microcontrollers from Infineon is the XC866. It features
75-150ns instruction cycle time at 26.67 MHz CPU clock (one waitstate for flash
access; no waitstate for ROM or XRAM access), 12 Kbytes of advanced program
flash (with ECC), 4 Kbytes of advanced data/program flash (emulated EEPROM), 256
Bytes RAM, 512 Bytes XRAM, 10-bit ADC (8 channels), three 16-bit timers, UART
(for LIN emulation) and SSC.
The XC866 has an embedded voltage regulator capable of accepting 3.3 to 5.0V,
and is available with 8 or 16 kBytes Flash at temperature ranges of -40 to 85 or
125 degrees C. All four types come in a lead-free 38-pin TSSOP. ROM versions
also will be available for high-volume production.
Microchip Technology has begun volume production
of four 16-bit dsPIC Digital Signal Controllers that offer performance speeds of
20 and 30 MIPS, self-programming capabilities via Flash memory, and industrial
and extended temperature ranges. The dsPIC30F3014 and dsPIC30F4013 extend the
package and memory range of the General Purpose Family, adding 24 and 48 Kbytes
of Flash program memory respectively. In addition, the dsPIC30F3010 and
dsPIC30F3011 Motor Control and Power Conversion Family DSCs feature 24 Kbytes of
Flash program memory and can operate at full speed using an internal oscillator.
The Enhanced Flash self-programming capability features a remote upgrade to the
Flash program memory, allowing code revisions in end-user applications. All four
new dsPICs are able to operate at 5 V, which is valuable for noise immunity and
minimizing voltage translation logic.
Additional features of the General Purpose dsPIC30F3014 and dsPIC30F4013 include
2 Kbytes of SRAM, 1 Kbyte of high-endurance EEPROM data memory, 12-bit A/D
converter with up to 13 signal channels and 100k samples per second, SPI, I2C,
and up to two UARTS. The dsPIC30F3014 features three 16-bit timers; the
dsPIC30F4013 has five timers plus CAN interface and CODEC interface.
Additional features of the Motor Control and Power Conversion dsPIC30F3010 and
dsPIC30F3011 include 1 Kbyte of SRAM, 1 Kbyte of high-endurance EEPROM data
memory, 6-channel motor control PWMs, 10-bit A/D converter with up to 9 signal
channels and 1 million samples per second, five 16-bit timers, SPI, I2C and up
to 2 UARTS (1 UART on dsPIC30F3010), and Quadrature Encoder Interface.
All are available today for general sampling and volume production in 40-pin
PDIP and 44-pin QFN or TQFP (except dsPIC30F3011, which is in 28-pin SDIP or
SOIC, or 44-pin QFN). Pricing for the dsPIC30F3014 is $5.63 each in 10,000-unit
quantities, and the dsPIC30F4013 is $7.25 each in 10,000-unit quantities.
Pricing for the dsPIC30F3010 is $5.45 each in 10,000-unit quantities, and the
dsPIC30F3011 is $6.24 each in 10,000-unit quantities.
At only 5.09 x 4.84 mm, Oki's new 33 MHz ML67Q4060 series are
the world's smallest 32-bit ARM7TDMI-based microcontrollers. The ML67Q4060
features 64 KB Flash program memory, while the ML67Q4061 features 128 KB. Each has 16
Kbytes RAM, 2-channel SPI, I2C, I2S, 2-channel UART, 32-bit real-time clock,
2-channel DMA controller, 40-channel GPIO, and 4-channel 10-bit ADC. They
operate at 2.25 to 3.6 V and come in 64-pin WCSP, with 64-pin LQFP and 84-pin
An additional series, the ML67Q4050 and ML67Q4051, integrates an external memory
controller (Flash ROM, SRAM, SDRAM, I/O device), and comes in a 144-pin LFBGA
A security function on the chip prevents theft of programs and data by making
the JTAG interface unusable with specific operations.
Sample shipments began in March, with volume production slated for June.
Renesas: Two New
50 MHz 32-bit CISC Microcontrollers
Renesas Technology America has announced the H8SX/1653F and H8SX/1651, two new
and faster models in the H8SX family of 32-bit CISC microcontrollers. Operating
at clock speeds as high as 50MHz, the new devices offer high performance and
deliver on-chip functionality that enables advanced designs of PC peripherals,
office equipment, consumer electronics products, industrial systems, POS
(Point-of-Sale) and smart card payment terminals. Both maintain upward code
compatibility with lower-performance devices in the popular H8 product line,
allowing for easy upgrade of existing designs.
Renesas launched the H8SX series last year with two 35MHz devices optimized for
consumer electronics products. Besides being almost 43 percent faster, the new
50MHz microcontrollers provide an expanded set of on-chip peripheral functions.
In particular, the serial communication interface (SCI), which supports both
asynchronous and clock-synchronous data transfers, has been increased to five
channels in the H8SX/1651 and six channels in the H8SX/1653F. The H8SX/1653F
also includes two channels that support high-speed asynchronous serial data
transfers and has a USB 2.0 (full speed) function. To allow engineers to perform
system debugging with the device mounted on the circuit board of the end
product, both microcontrollers incorporate an on-chip, JTAG-compliant debugger
The H8SX/1653F has 384 KBytes of on-chip flash memory that can be accessed in a
single cycle, even at the full 50MHz clock speed. The H8SX/1651 has no flash or
ROM, and therefore must access external ROM. Both chips incorporate a vector
base register (VBR) that improves interrupt responsiveness and system
throughput. A boot function for writing program data to external ROM allows
programs to be rewritten after the ROMless H8SX/1651 is mounted on a circuit
board. Both microcontrollers have 40 KBytes of on-chip RAM.
The sample price of the H8SX/1651, available in 120-pin TQFP or LQFP, is $4.73.
For the H8SX/1653F, available in 120-pin TQFP, the sample price is $18.70. Both
will be available in June of 2005.
Renesas: 24 New
R8C/Tiny 16-bit Flash Microcontrollers
Renesas Technology Corp. has added 24 new models to the R8C/Tiny
Series of small, low-pin-count, high-performance 16-bit microcontrollers with
on-chip flash memory. The new models are classified into six groups: the 48-pin
package R8C/20, R8C/21, R8C/22 and R8C/23 groups, and 52-pin package R8C/24 and
R8C/25 groups. Sample shipments will begin in Japan in June 2005 for 20 models,
and in December 2005 for the four R8C/24 and R8C/25 models (versions with 48 or
64 kbytes of on-chip flash memory).
An advanced 16-bit timer offers a maximum operating speed of 40 MHz, twice that
of previous R8C/Tiny Series models. This doubling of the operating speed offers
improved timer counter resolution, enabling fine motor control to be implemented
with a higher degree of precision.
LAN support is provided by new interfaces for the CAN and LIN standards. A CAN
interface is provided in the R8C/22 and R8C/23 groups, and a LIN interface in
all groups, enabling automotive and industrial products offering CAN and LIN
support to be implemented at low cost.
With these new R8C/Tiny Series models, the time for transition from flash memory
rewriting to interrupt handling has been shortened to less than 1/20 of the time
required in previous models. This allows instantaneous transition to interrupt
handling, improving product responsiveness and extending the application range.
In addition, data can be written to a flash memory block while data in another
block are being erased. This facilitates the replacement of previously used
external EEPROMs with on-chip flash memory for data storage.
The four groups R8C/20, R8C/21, R8C/22, and R8C/23 include high-reliability,
high-temperature-range (-40 to 125şC) products for use in automotive
applications. These groups include models with on-chip CAN and/or LIN
interfaces. A watchdog timer, EEPROM, and sub-microcontroller that have
previously been separate external components can be implemented with a single
R8C/Tiny Series chip.
The TMS320C2000 series digital signal
controllers provide a combination of MCU integration and ease-of-use with the
performance and system cost benefits of digital signal processing (DSP)
The TMS320F2801, F2806 and F2808 controllers integrate a complete set of control
system capabilities -- pulse width modulation (PWM) generation, time stamping,
sensor capture, analog-to-digital conversion, communication interfaces, and
program and data storage -- into a single device, reducing system cost, board
space and system complexity. The controllers also offer an improved suite of
peripheral features and modes with specific application uses and benefits. The
F2808 controller also provides a highly accurate, 16-channel, 12-bit
analog-to-digital converter (ADC) with a conversion speed up to 6.25 MSamples/s,
providing a single-chip blend of 32-bit DSP and high-performance analog
Their new PWM technology provides 16 bits of accuracy in a 100 KHz control loop
and 12 bits at 1 MHz. F28x controllers’ unique accuracy eliminates ‘limit cycle’
issues, enabling power supply designers to employ digital control in high
These new controllers contain from 32 to 128 KB Flash memory, 12 to 36 KB RAM,
up to four SPI channels, up to two Serial Communications Interfaces, I2C, and up
to two CAN interfaces.
The F28x DSP core architecture features a 32-bit wide data path and mixed
16-/32-bit instruction set for improved code density. It provides complete
control system capabilities from signal input through the on-chip ADC,
quadrature encoder pulse (QEP), and timer captures and compares through signal
output with up to 16 independent PWM channels, enabling a single F2808 to
control up to five independent three-phase motors. Each of the PWM channels,
timers, QEPs, and captures can be controlled independently or synchronized
Sampling now, the TMS320F2801 controller is $4.95, the TMS320F2806 is $7.45, and
the TMS320F2808 is $9.95, all in production quantities. Each device will be
qualified to the Q100 automotive standard and available in both a 100-pin LQFP
and 100-ball BGA package, with volume production for all three devices scheduled
for the third quarter of 2005.
