Corporation's Embedded News Digest, your source for microcontroller and
embedded system news.
This month's issue:
The new PIC18F4680, PIC18F2680, PIC18F4585 and PIC18F2585
microcontrollers feature 48K bytes or 64K bytes of Flash program memory with
self-programming capability, allowing the microcontroller to be programmed after
being placed in a circuit board.
Each microcontroller features Microchip’s ECAN module, a CAN
2.0B interface with transmit and receive (TX/RX) buffers that can be configured
for standard CAN applications, DeviceNet protocol support or a FIFO state
Additional features of the new microcontrollers include: 32
kHz to 32 MHz (8 MIPS) internal oscillator; Fail-safe clock monitor;
Operation from an external crystal or clock source for 10 MIPS performance at 40
MHz; 3K bytes of RAM and 1K byte of high-endurance EEPROM data memory;
Analog-to-digital converter with up to 11 channels x 10-bit resolution and 100
ksps; Two analog comparators with internal voltage regulator circuitry,
programmable brownout detect, and programmable low-voltage detect; One
Capture/Compare/PWM module, 1 Enhanced Capture/Compare/PWM module;
Operating voltage range of 2.0 – 5.5 volts, and an extended temperature range of
-40°C to +125°C; Serial I/O features include SPI and I2C modules, and a USART
module with Local Interconnection Network (LIN) protocol support.
The PIC18F2680 and PIC18F2585 are available in 28-pin SDIP and
SOIC packages, the PIC18F4680 and PIC18F4585 in 40-pin PDIP, and 44-pin TQFP or
The new SH7780, a 32-bit microprocessor incorporating the
SH-4A, the high-end CPU core in the SuperH™ Family, and a PCI bus controller,
delivers 720 MIPS and 2.8 GFLOPS at 400 MHz.
In addition, the SH7780 incorporates an on-chip floating point
unit (FPU) with a maximum operating speed 400 MHz. The FPU supports both
single-precision and double-precision arithmetic operations and delivers a
maximum processing performance of 2.8 GFLOPS when operating in single-precision
mode. Furthermore, hardware support for sine/cosine arithmetic operations
contributes to high-speed rendering of 3-D graphics.
The SH7780 employs three kinds of bus: a 32-bit bus for
connections to double data rate synchronous DRAM (DDR-SDRAM), a 32-bit bus for
PCI bus connections, and a 32-bit local bus for connecting to flash memory,
SRAM, etc. These three external buses can be operated simultaneously, allowing
for efficient data transfer and improved performance.
On-chip peripheral functions in the SH7780 are an interrupt
controller (INTC), a real-time clock (RTC), a watchdog timer (WDT), and an
interface for connecting to an audio CODEC IC, in addition to other peripheral
modules such as a serial interface.
The package is a 449-pin BGA (21 mm × 21 mm). Samples are expected in November
2004 with a unit price of 6000 Yen.
Renesas announced a total of eight M16C/6NK and M16C/6NL
16-bit microcontroller models, incorporating large-capacity flash memory and a
CAN (controller area network) interface controller.
Flash memory for program storage has been expanded from the
maximum 256 Kbytes of the current M16C/6N Group to a maximum of 512 Kbytes. At
the same time, maximum RAM capacity has been increased from 10 to 31 Kbytes.
There is a choice of 512- or 384-Kbyte flash memory. Four Kbytes of flash memory
usable for program and data storage are also provided.
The M16C/6NK series has two on-chip CAN-compatible controller
channels, while the M16C/6NL has one channel. Integrated peripheral functions
include a multifunction timer, serial I/O, I2C bus, A/D converter,
D/A converter, DMA controller, CRC (Cyclic Redundancy Check) operation circuit
and watchdog timer.
The operating voltage range has been extended to a 3.0 to 5.5
V range that covers the 3.3 V used by consumer devices. High-speed operation,
with a 24 MHz maximum operating frequency and 41.7 ns minimum instruction
execution time, is implemented across the entire voltage range.
Housed in a small 100-pin LQFP (14 mm × 14 mm) or 128-pin LQFP
(14 mm × 20 mm) package, unit prices range from 1600 Yen to 1850 Yen.
The new M32192 Group microcontrollers use an M32R-FPU
32-bit RISC CPU core incorporating a single-precision FPU (Floating Point Unit).
The maximum operating frequency is 160 MHz, giving these microcontrollers
twice the speed and performance of current 80 MHz models.
The new microcontrollers feature the addition of a DRI (Direct
RAM Interface) function that enables data (such as image data from collision
avoidance systems) to be fetched directly into on-chip RAM from off-chip,
allowing required data to be selected and fetched at a maximum speed of 40
Mbytes per second without CPU intervention. To hold this selected data, the
on-chip RAM capacity has been approximately tripled to 176 Kbytes from the 64
Kbytes of current models.
The new M32192 Group maintains pin arrangement compatibility
with the current M32176 Group, while offering additional peripheral functions
including a PWM (Pulse Width Modulation) output timer with a shorting prevention
function, a multiply-by-4 event count timer, and an A/D converter with
simultaneous 2-channel sampling capability.
The CAN interface has been equipped with 32 message slots per
channel instead of the previous 16, reducing the software overhead. A choice of
8 or 16 bits data length for the synchronous serial interface simplifies
connection to external EEPROMs.
The package used is a small 144-pin LQFP (20 mm × 20 mm).
Sample price is 7000 Yen.
The new C8051F064 product family includes the C8051F065,
C8051F066 and C8051F067, which offer a 25 MIPS 8051 core and a
choice of 32 kB or 64 kB of Flash memory in a 64-pin or 100-pin package. The new
MCUs also have low-power, dual 16-bit, 1 Msps (mega sample per second)
ADCs with ±0.75 least significant bit (LSB) integral nonlinearity (INL) error,
89 dB SINAD and only 20 mW power consumption per ADC.
On-chip peripherals include two UARTs, SMBus™ and SPI™ bus
serial ports as well as a two percent accuracy precision internal oscillator
that eliminates the need for an external crystal or resonator.
Pricing begins at $9.98 in quantities of 5,000. The devices
are packaged in either a 100-pin TQFP with 59 digital I/O or 64-pin
TQFP with 24 digital I/O.
STMicroelectronics has introduced a new 3V microcontroller
series within its ST7232x general-purpose MCU portfolio. The Flash and ROM
ST72324L 3V devices are pin-to-pin compatible with their 5V counterparts.
The new devices are designed to operate on a 2.85V to 3.6V
power supply, over the -40 to +85şC temperature range. They are available with
8-Kbyte, 16-Kbyte or 32-Kbyte of Flash program memory, or with 8-Kbyte or
16-Kbyte of fully compatible ROM for cost-sensitive high-volume applications.
All devices provide four power saving modes, include two 16-bit timers plus
Watchdog and Real Time Clock (RTC), SCI (Serial Communications Interface) and
SPI (Serial Peripheral Interface), and a 10-bit ADC (Analog to Digital
Converter) with up to 12 input channels. An integrated Reset circuit with
user-settable low voltage detector saves external components. The devices are
available in TQFP44, TQFP32 and SDIP32 packages.
The 3V devices are available now with a pricing range, for
100k units, from US$1.70 (44-pin with 32K of Flash) to US$0.90 (32-pin with 8K
The new C6711 DSP provides 1500 Million Floating-Point
