The RH850/D1M 32-bit microcontroller targets vehicle instrument cluster applications for enhanced information and safety. MCU has up to 3.6 Mbytes of video DRAM, 3.75 or 5.0 Mbytes of code flash, 512 Kbytes of local RAM, and a newly developed high-function graphics engine supported by an efficient graphics library. It operates at 160 or 240 MHz with an 8 Kbyte / 4-way associative instruction cache. External memory interfaces are also available.
There are low and high speed internal oscillators, seven timers and a RTC, 24 PWM generators, serial, CAN, LIN, and Ethernet interfaces, and optional Media Local Bus. It has an 80 or 240 MHz GPU, 2 CRC video output checkers, a LCD Bus Interface, an intelligent stepper motor driver and operates from a 3.3 V supply. The chip has four package sizes from 21 x 21 to 27 x 27 mm with 176 to 484 pins. The RH850/D1L version is available for lower performance instruments.
