This document describes the features and characteristics of the MB90350 series microcontrollers, which are especially designed for automotive and industrial applications. The main feature is the on-board CAN interface, which supports a flexible message buffer scheme and offers more functions than a normal full CAN approach. With the 0.35 µm CMOS technology, the microcontrollers have on-chip FLASH-ROM program memory up to 128 Kbytes. An internal voltage booster and voltage regulator provide advantages in terms of EMI and power consumption. The microcontrollers also feature a 4-channel Output Compare Unit, a 6-channel Input Capture Unit, and 2-channel UART for communication purposes.
