MCU 16Bit CISC 32KB EPROM 5V Automotive 80Pin PQFP T/R

Overview

The MC68HC912B32 microcontroller unit MCU is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit CPU12, 32-Kbyte flash EEPROM, 1-Kbyte RAM, 768-byte EEPROM, an asynchronous serial communications interface SCI, a serial peripheral inter-face SPI, an 8-channel timer and 16-bit pulse accumulator, a 10-bit analog-to-digital converter ADC, a four-channel pulse-width modulator PWM, and a J1850-compatible byte data link communications module BDLC. The chip is the first 16-bit microcontroller to include both byte-erasable EEPROM and flash EEPROM on the same device. System resource mapping, clock generation, interrupt control and bus interfacing are managed by the Lite integration module LIM. The MC68HC912B32 has full 16-bit data paths throughout, however, the multiplexed external bus can operate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems.
