This month's issue:
Atmel® Corporation announced four new members
of the LCD AVR®Flash Microcontroller family. The mega329, 649, 3290 and 6490 are
designed to address the requirements of portable and battery-operated
applications like home appliance controllers, Audio/Video equipment and health
care products. The mega329 and 649 have an integrated 100-segment LCD controller
and are housed in a 64-pin package while the mega3290 and 6490 have a
160-segment LCD controller and are available in a 100-pin package.
The LCD AVR family of Flash microcontrollers
consumes only 300µA at an operating frequency of 1 MHz and has an unrivaled
throughput of 2 MIPS per milliwatt. In the Power-down mode, all peripherals,
with the exception of external interrupts, are turned off and power consumption
drops to 100nA. These parts are extremely responsive to external events in both
active and power down modes. Interrupts on up to 18 inputs can wake the part
from a power down mode in less than one microsecond, which is a 6x improvement.
To further reduce power consumption, the CPU
clock is controlled by software. The designer can select a high clock frequency
for computation-intensive operations, and slow the clock to 32 kHz or less to
perform simple control functions. This means products designed with the LCD AVR
family will be able to run up to 10 times longer on the equivalent battery power
when compared to traditional microcontroller solutions.
The mega329 and 3290 are available today. The
10,000-unit prices are US$4.50 and US$4.95 respectively. The mega649 and 6490
will be available in Q1 2005 and priced at US$5.25 and US$5.75 with volume
production expected in the second half of that year.
Atmel's new ATR2740 digital audio broadcast
(DAB) baseband IC is based on a stndard ARM core and requires only two external parts (a simple crystal and
an 8MB Flash memory) to run the full DAB function. All RAM
functions, such as interleaving or program memory, are incorporated into the
device, same as the analog-to-digital converter. The ATR2740 works perfectly
together with Atmel's DAB front-end devices U2730B and U2731B. The ATR2740 also
provides a wide variety of supported interfaces: UART; USB; and SPI are
available for control functions, SSO, SFCO and RDI interfaces as well as two
audio outputs (I2S or SPDIF) implemented as data interfaces.
At a full decoding data bit rate of 1.8 Mbit/s,
the device's power consumption is as low as 180 mW, which is the industry's
lowest such value. The ATR2740's outstanding processing power enables the device
to decode the full DAB data rate of 1.8 Mbit/s, which is needed especially for
video and data streaming. In addition, the device provides sufficient unused
processing power available on the ARM controller for customer software such as
user interfaces. A complete MP3 player can be run without the need to add extra
hardware to the device.
A complete set of hardware and software
tools, including comprehensive documentation, is available on request. The
software to run a DAB radio is available free of charge. This software covers
all DAB-related functions and features as specified in Eureka 147.
Samples of the new ATR2740 baseband processor
device in LQFP and BGA packages are available now. Pricing starts at US$16.00 in
quantities of 10,000.
The new 56F8100 series includes 40 MIPS processing power, on-chip flash memory and a
full assortment of analog and digital peripherals. This series offers a tailored
feature set, in comparison to the 56F8300 series, to balance processing power
with value. Specific 56F8100 series features include: 40 MHz/MIPS performance;
Extended industrial temperature range (-40 to +105 degrees Celsius); 32 KB to
512 KB flash memory, with multiple package options from 48 to 160 LQFP; Pulse
Width Modulators (PWM); Four-input quadrature decoder; Multiple timers,
general-purpose input/output and serial interfaces; and High-speed 12-bit
analog-to-digital converter.
For designers who still need the higher memory and performance of the 56F8300
series, Freescale is introducing three 56F836x devices with 60 MIPS performance,
512 KB on-chip program flash and dual CAN capability.
The 56F8300 series, introduced in 2003, targets higher-level applications
requiring larger flash memory sizes, wider temperature ranges (-40 to +125
degrees Celsius) and CAN interfaces. This series is optimal for complex
automotive motor control applications like electronic power assisted steering.
The devices also drive sophisticated industrial motor control applications such
as electronic currency recognition for vending machines.
All of the latest 56F8100 and 56F8300 devices
are available now. Pricing varies based on device feature set, flash size and
packaging. Suggested resale pricing for the 56F8100 series, in 10,000-piece
quantities, ranges from US$6.19 to US$16.86. Suggested resale pricing for the
56F836x devices, in 10,000-piece quantities, ranges from US$19.01 to US$22.14.
Goal’s VERSA
Microcontroller Families of cost-effective, FLASH 8051-based
microcontrollers are pin-to-pin/drop-in replacements for industry standard 8051
MCUs. In
addition to its drop-in replacements parts, Goal also offers low-cost, SoC
solutions for signal conditioning, data acquisition, processing and control
applications with its VERSA MIX Family (VMXxxxx) of fully-integrated
mixed-signal 8051 microcontrollers.
Goal can supply
the most commonly used 3.3 and 5 Volt 8051 microcontrollers in 4 weeks or less,
at a competitive price.
The DS80C410/DS80C411 network microcontrollers offer the
highest integration available in an 8051 device. Peripherals include a 10/100
Ethernet MAC, three serial ports, an optional CAN 2.0B controller, 1-Wire®
Master, and 64 I/O pins. The DS80C410 and DS80C411 also include 64 Kbytes
internal SRAM for user application storage and network stack.
To enable access to the network, a full
application-accessible TCP IPv4/6 network stack and OS are provided in the ROM.
The network stack supports up to 32 simultaneous TCP connections and can
transfer up to 5 Mbps through the Ethernet MAC. Its maximum system clock
frequency of 75 MHz results in a minimum instruction cycle time of 54 ns. Access
to large program or data memory areas is simplified with a 24-bit addressing
scheme that supports up to 16 MB of contiguous memory.
To accelerate data transfers between the microcontroller and
memory, the DS80C410 and DS80C411 provide four data pointers, each of which can
be configured to automatically increment or decrement upon execution of certain
data pointer-related instructions. High-speed shift, normalization, accumulate
functions and 32-bit/16-bit multiply and divide operations are optimized by the
DS80C410/DS80C411 hardware math accelerator.
The DSC80C410 is available now in 100-pin LQFP at $8.93
in quantities of 1,000 or more, or $10.57 in quantities of under 25. The
DSC80C411 will be available soon.
NEC Electronics Corporation has introduced the
78K0/Kx2 Series of 8-bit MCUs with embedded flash memory. The comprehensive
series consists of 48 products offering memory capacities ranging from 8 to 128
kBytes and 30- to 80-pin packages. The 78K0/Kx2 Series is targeted for use in a
wide range of home appliances, consumer electronic products, industrial
equipment, automotive systems, lighting systems and sensors.
The 78K0/Kx2 Series offers operating speeds up to 20 MHz and
power supply voltages ranging from 1.8 to 5.5V while reducing operating current
to 2.5 mA, less than one-third of similar mask ROM MCUs. Additionally, all of
these features are available without a cost premium, as products in the 78K0/Kx2
Series have price points comparable to previous mask ROM products from NEC
Electronics manufactured in 0.35-micron process technology.
Samples of the 78K0/Kx2 are scheduled to begin shipping in January 2005. Pricing
for individual products in the 78K0/Kx2 line will vary based on the
configuration. For example, the high-end 78K0/KF2 with 60 KB of flash memory is
priced at US$5 per unit. Mass production is scheduled to begin in April 2005,
and NEC Electronics expects production volumes of the various configurations of
the 78K0/Kx2 Series to reach three million units per month by 2006.
The new LPC2130 Series (LPC2131, LPC2132, LPC2134,
LPC2136 and LPC2138) is armed with up to 512 KBytes of 128-bit-wide Flash
memory. This enables four 32-bit words to be accessed in a single fetch,
allowing the CPU to run at 60 MHz (54 MIPS) without wait-states. Contrasting
with other ARM7 MCU implementations, this single difference delivers up to four
times the performance. The Flash memory also offers built-in error correction
for improved reliability.
The five new devices are footprint-compatible with key
features that include: 16/32-bit ARM7TDMI-S CPU with ARM debug and embedded
trace interfaces; 47 bit-addressable GPIO pins; 3 V single-voltage supply with
Brown-Out Detect and Power-On Reset; Dual 8-channel 10-bit ADC and a
10-bit DAC; Tiny QFP and HVQFN (9mm x 9mm) 64-pin packages.
The LPC2131, LPC2132, LPC2134, LPC2136 and LPC2138 have
32/64/128/256/512 KBytes of on-chip Flash program memory and 8/16/32 KBytes of
on-chip static RAM respectively. The LPC2131, LPC2132 and LPC2138 are available
now. The LPC2134 and LPC2136 will be available in early Q1 2005.
The SH7619 is the first Renesas microprocessor to offer an
on-chip IEEE802.3-compliant MAC and a PHY transceiver in a single chip. These
features simplify development of a 10/100 Mbps Ethernet LAN connection function,
and enable the number of component parts to be reduced. The SH2 CPU core has a
maximum operating frequency of 125 MHz at 13 MIPS, enabling high-speed execution
of TCP/IP and similar protocol processing, and the implementation of
high-performance systems.
A host interface function is also included that allows easy
connection to a main microprocessor for system control, for example, with the
SH7619 being recognized by the main microprocessor as an SRAM-equivalent device.
This function comprises a 16-bit interface bus and two SRAM banks each with a 1
Kbyte linear address space, providing for direct reading and writing from the
main microprocessor by access to this SRAM, and enabling data downloaded via an
Ethernet to be transferred to the main microprocessor at high speed.
The device is also equipped with an HIF boot mode, which allows a program in
SDRAM connected to the SH7619 to be downloaded via the host interface from flash
memory connected to the main microprocessor. This eliminates the need for
external flash memory for SH7619 program storage, enabling the number of
component parts to be further reduced.
A general-purpose DMA controller is included that provides high-speed data
transfer to and from external memory, enabling network data throughput to be
increased. In addition, the provision of on-chip serial I/O interfaces allows
connection to a voice CODEC or similar device, facilitating the implementation
of a VoIP system, for example.
The SH7619 employs a small (13 mm × 13 mm) 176-pin BGA package that helps
minimize product size.
On-chip debugging functions are included that enable real-time debugging at the
maximum operating frequency, and the small PC card sized E10A-USB can be used as
an emulator.
Future plans for enhancement of the lineup of on-chip Ethernet controller
products include the development of models offering faster CPU processing speed,
on-chip flash memory, and built-in security functions.
Sample shipments of the SH7619 will begin in December 2004
within Japan priced at Ą1700.
The CP2102 is the industry's smallest and most
integrated single-chip USB-to-UART bridge. It simplifies the upgrade from RS232
to USB by providing a complete solution with royalty-free drivers that eliminate
the need for additional software. The highly-integrated bridge reduces board
space, simplifies design and reduces development time.
The CP2102 features on-board EEPROM, a voltage
regulator, a USB transceiver and an integrated internal oscillator, eliminating
the cost and complexity of a crystal and other external components typically
required in USB applications. The device also includes a complete USB 2.0
full-speed function controller, bridge control logic and a UART interface with
transmit/receive buffers and modem handshake signals in a small 5 x 5 mm
package.
The CP2102 provides enhancements from Silicon
Laboratories' CP2101 architecture and is easily implemented into existing
designs without any design modifications. The CP2102 includes a user-friendly
wizard for customizing non-standard baud rates and storing OEM vendor ID (VID)
and product ID (PID) information.
Silicon Laboratories offers the CP2102 packaged
in a tiny 5 x 5 mm 28-pin MLP that is pin compatible with the CP2101. Pricing
begins at $2.42 in quantities of 10,000.
The new SST89E/V52RD2/RD, SST89E/V54RD2/RD and
SST89E/V58RD2/RD microcontrollers combine SST's proprietary SuperFlash
technology with a dual-block flash architecture that supports in-application
programming (IAP) and features their unique SoftLock security feature. In
addition to up to 32 Kbytes of on-chip SuperFlash memory, the new RD2/RD product
family offers 1 KByte of on-chip SRAM and fast clock speeds of up to 40 MHz.
The low-cost RD2/RD microcontrollers provide customers with an ideal solution
for developing microcontroller-based application specific products for
high-volume applications in industrial, PC, digital consumer, wireless and
networking markets.
The unique architecture of the RD2/RD enables users to map the
flash memory into two independent blocks. The primary memory block-0 is
comprised of 8 KBytes (SST89E/V52RD2/RD), 16 KBytes (SST89E/V54RD2/RD) or 32
KBytes (SST89E/V58RD2/RD) of SuperFlash EEPROM with a 128-Byte sector size, and
occupies the internal ROM space for an 8051-compatible microcontroller. The
secondary memory block-1 houses 8 Kbytes of SuperFlash EEPROM, also with a
128-Byte sector size, and can be used as either electronically erasable
nonvolatile data or code storage. The RD2/RD microcontrollers can be
reprogrammed from a single-voltage 3V or 5V power supply.
Samples of the RD2/RD microcontrollers are available now. SST
expects production quantities to be available by the end of Q4. The
SST89E52RD2-40-C-NJ is priced at $1.20 each; the SST89E54RD2-40-C-NJ is priced

STMicroelectronics has begun volume production of the ST72F561
8-bit microcontroller, which integrates CAN and LIN bus interfaces, plus 60
kBytes of Flash memory. In its TQFP32 7x7mm package, it is thought to be the
smallest MCU on the market to offer a CAN bus and two SCI interfaces. It also is
available in TQFP44 and TQFP64.
The ST72F561 is the lead product in a family of car networking devices
addressing CAN and LIN bus applications. In addition, its low cost, low power
requirement, and flexible package options make it ideal for many industrial and
consumer applications needing CAN or UART communication.
The MCU family is produced in 60-kByte and 32-kByte Flash memory variants; 60k,
48k, and 32-kbyte ROM versions will also be available soon. All feature a
powerful CAN cell fully supporting 29-bit identifiers, with enhanced message
filtering, to reduce software overhead and CPU load even in complex CAN
networks, and to provide higher-than-normal network performance. The Window
Watchdog provides more robust system monitoring than a traditional simple
watchdog module. Two LINSCI interfaces, with built-in LIN protocol frame break
support, provide LIN communication with reduced CPU load compared to a UART-based
solution. The ST72F561 can perform as either a LIN Master or Slave.
Power consumption in Standby mode is very low -- typically less than 1 µA -- and
is less than 50 µA when using its associated Auto Wake-Up feature.
The Flash MCU is available in volume now, priced at US$3.75 each in quantities
of 25,000 in the TQFP64 package with 60 kBytes of program memory. Volume
production of the 60-kByte ROM version is planned for Q2 2005.
