Mitsubishi Electronics Introduces Powerful 8-, 16-, and 32-Bit Microcontrollers to North American Automotive Market
DETROIT--Oct. 16, 2000--Capitalizing on Mitsubishi Electric Corporation's success in the Japanese and European automotive microcontroller (MCU) markets, the Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., today introduced powerful "7600 Series" 8-bit, "M16C" 16-bit, and "M32R/E" 32-bit controller area network (CAN) MCUs for the North American automotive market. Focused on safety, comfort, and convenience, Mitsubishi's CAN MCUs provide high performance, energy efficiency, and feature-rich intelligence for key automotive systems such as airbag/occupant sensing, electronic power steering (EPS), anti-lock brake system (ABS), powertrain, and body control applications.
"Mitsubishi brings extensive worldwide automotive microcontroller experience to North America," said Cristian Tomescu, product marketing manager for automotive microcontrollers at Mitsubishi Electric & Electronics USA, Inc. "Our leadership in developing microcontrollers with embedded flash memory, as well as a wealth of features, will enable automakers to provide more intelligent cars to their customers."
M16C/6N 16-Bit CAN MCU
Mitsubishi's M16C/6N 16-bit CAN MCU Series delivers high-end performance functionality with low power consumption to airbag/occupant sensing, ABS, EPS, dashboard, and suspension control systems. Built using a high-performance silicon-gate CMOS process technology and powered by the M16C/60 Series CPU core, the device is also equipped with up to two CAN control modules and is compliant with the CAN 2.0B specification. The M16C/6N contains up to 256 Kbytes of flash memory to facilitate easy and fast in-circuit reprogrammability (256 Kbytes in 8 seconds) and provides up to 1 Mbyte of address space through memory expansion. The device allows a maximum operating frequency of 20 MHz at 5 volts and a minimum instruction execution time of 62.5 ns. It is available in a 100-pin QFP package.
The M16C/6N Series has other key features, including:
| -- | RAM: Up to 10 Kbytes |
| -- | A-D converter: 10-bit x 26 channels, 3.3-u conversion speed |
| -- | D-A converter: 8-bit x 2 channels |
| -- | Multifunction 16-bit timer (5 output timers, 6 input timers, PWM operation allowing three-phase motor control) |
| -- | Watchdog timer |
| -- | Up to four serial communication channels (3 UART or clock synchronous, 1 clock synchronous) |
| -- | Cyclic redundancy check (CRC) feature |
| -- | 87 programmable I/O ports |
| -- | Key On Wake Up interrupts |
| -- | Temperature range of -40 to +85 degrees Celsius |
Other key M16C/6N features suitable for airbag/occupant sensing control are:
-- On-chip ring oscillator that maintains internal clock
operation and can activate airbag deployment, even after the
main clock oscillator is lost
-- EMI (electromagnetic interference) countermeasures to enhance
noise immunity
M32R/E 32-Bit CAN MCU - M32170 and M32171 Groups
The M32R/E Series of 32-bit CAN MCUs is a powerhouse for high-end automotive system applications such as powertrain, engine, and transmission control, as well as for high-end airbag deployment systems. The M32170 and M32171 Groups of the M32R/E Series are based on Mitsubishi's M32R 32-bit RISC CPU core, which provides five stages of pipelined processing for high-speed applications of up to 40 million instructions per second (MIPS). They also feature one CAN channel that is compliant with the CAN 2.0B specification. The M32170 Group provides up to 768 Kbytes of on-chip flash memory for high-capacity reprogramming (768 Kbytes in 24 seconds). It is available in a 240-pin QFP and a 255-pin FBGA package. The M32171 Group is a scaled-down version of the M32170 family, features up to 512 Kbytes of flash memory, and comes in a 144-pin LQFP package.
Other key features built-in to the M32170 Group include:
-- Multi-junction timers (MJT) for flexible timer configuration:
64-channels
-- Real-time debugger (RTD) that designers can access via a
serial port independently of the CPU
-- DMAC: 10 channels
-- Internal high speed multiplier that supports single-cycle MAC
operations (32 x 16 plus 56-bit)
-- Two independent 10-bit A-D converters that support 32 channels
-- 1-channel full CAN circuit
-- JTAG boundary scan architecture
-- Up to 155 programmable I/O ports
-- High-speed serial communication I/O ports: 6 channels
-- 40-MHz clock at -40 degrees to +85 degrees Celsius (32-MHz
clock is possible during operation as high as +125 degrees
Celsius)
"7600 Series" 8-Bit CAN MCU
Mitsubishi's M37630 8-bit CAN MCU provides a cost-effective MCU solution for a variety of body control module systems (such as door, seat, window, mirror, sun roof, lighting controls, and keyless entry systems), as well as satellite airbag control systems. Based on Mitsubishi's 740 Family, the M37630 is built using a high-performance silicon-gate CMOS process technology and is powered by Mitsubishi's 7600 Series CPU core, which features a minimum instruction execution time of 0.2u. The device contains one CAN channel that complies with the CAN 2.0B specification, 16 Kbytes of ROM and 512 bytes of RAM, and 36 programmable I/O ports with overload protection. It operates at a maximum frequency of 10 MHz at 5 volts and consumes only 55 mW at the highest operating speed. The M37630 is available in a 44-pin QFP package.
