The SH7231 series is a high-end single chip microcontroller incorporating the SH-2A core and FPU. SH7231 operates at max 100MHz. The SH7231 series incorporates 1MB flash memory, 32KB RAM (for high speed access) and 12KB RAM( for data retention). The SH7231 group also incorporates various communication interfaces such as a CAN, SCI, SCIF, RSPI, LVDS receiver I/F etc. As others function, the SH7231 group incorporates various peripheral function suitable for industrial application AC servos, general-purpose inverters and robots, such as a 16-bit multifunction timer unit (MTU2/MTU2S) , a 10-bit A/D converter, and key scan controller (KEYC) that be able to control the key of max 80 input. SH7231 supports the deep-software-standby-mode suitable for machinery to drive with battery. KEYC and TIM32C can be working at deep software standby mode, and the datas of 12KB RAM (for data retention) are able to keep at deep software standby mode.
