Mitsubishi Electric's New 32-Bit Automotive MCU Offers Industry's Largest Flash Memory Capacity

SUNNYVALE, Calif. - October 2, 2002 - The Electronic Device Group of Mitsubishi Electric & Electronics USA, Inc., furthered its commitment to the North American automotive market by introducing two M32R/ECU 32-bit microcontrollers designed for high-end, controller area network (CAN) automotive applications, such as engine control, airbag system, and EV (motor control), as a cost-effective, high-performance alternative to microprocessors. The new devices, dubbed the M32R/ECU#5 (M32180 Group) and M32R/ECU#5HL (M32182 Group), offer up to 1 Mbyte of flash memory - the industry's largest flash capacity - incorporate a more advanced M32R floating point unit (FPU) core, boost clock speed up to 80 MHz, and operate throughout a wide temperature range (-40 to +125 degrees C).

"Mitsubishi Electric's M32R/ECU microcontrollers are an industry leader in on-chip flash memory capacity, and the latest generation of devices continues that tradition," said Richard Sessions, director of embedded systems at Mitsubishi Electric & Electronics USA, Inc. "Adding the FPU and doubling the processing speed accelerates performance to a microprocessor level in high-end automotive systems for a more cost-effective value. Mitsubishi Electric accelerated the process of debugging code with our new JTAG Interface With Tracing development tool, so customers can get to market faster."

Powerful M32R-FPU Core

The new generation of devices incorporates an FPU into Mitsubishi Electric's original compact M32R 32-bit high-performance RISC core. The new core is fully IEEE 754 compliant for single-precision operations and supports all exceptions defined in the IEEE 754 specification. The FPU greatly boosts the operation-speed performance of the new M32R microcontrollers, reducing single-precision instruction time by 95 percent and cutting in half the execution time of double-precision instructions, compared to previous-generation devices. The core also executes most frequently used instructions in one clock cycle, as well as compound instructions that execute two operations in one cycle.

The M32R-FPU core is capable of high code efficiency because its instruction set accommodates 16-bit and 32-bit instructions. The FPU incorporates multiply-accumulate and difference-of-products instructions that are suitable for Fast Fourier Transform (FFT) butterfly computation, as well as DSP-function instructions for the built-in multiplier-accumulator.

In addition, the M32R-FPU core supports a wide logical address space of 4 Gbytes without requiring segment switching, thus resulting in higher computational efficiency.

Large-Capacity Flash Memory

The new M32R/ECU devices offer large DINOR flash memory capacity to increase productivity at the development of manufacturing stages, and to contribute to improved maintainability in the field. The M32R/ECU#5 offers 1,024 Kbytes of flash memory with 48 Kbytes of RAM, and the M32R/ECU#5HL offers 384 Kbytes of flash memory and 64 Kbytes of RAM. Both devices offer memory expansion, which allows designers to add external discrete memory capacity.

Mitsubishi Electric's DINOR flash memory enables customers to program using a single 3.3- or 5.0-volt power supply. Designers can program quickly at a rate of 64 Kbytes every two seconds, regardless of the operating frequency. The devices support serial programming or software-based CPU programming as well as block erase and collective erase modes, giving designers more flexibility. The flash memory even provides a security function that protects against unauthorized readout or modification by any third party.

JTAG Interface With Tracing Development Tool

The new M32R/ECU devices incorporate a special tracing tool into the JTAG interface to streamline the code debugging process. The tool captures many clock cycles of code execution history so that designers can quickly narrow a coding problem to its source and make corrections, enabling faster time-to-market development.

Broad Development Tools Support

The M32R/ECU family is supported by proprietary and third-party development tools, such as system modeling software, real-time operating systems, C code generators, debugging and data calibration, and flash programming tools.
