MC68HC912BL16

Technical Summary

16-Bit Microcontroller

1 Introduction

The MC68HC912BL16 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip pe-

ripherals including a 16-bit central processing unit (CPU12), 16-Kbyte flash EEPROM, 512-byte RAM,

512-byte EEPROM, an asynchronous serial communications interface (SCI), a serial peripheral inter-

face (SPI), an 7-channel timer and 16-bit pulse accumulator, an 10-bit analog-to-digital converter

(ADC), and a four-channel pulse-width modulator (PWM). System resource mapping, clock generation,

interrupt control and bus interfacing are managed by the Lite integration module (LIM). The

MC68HC912BL16 has full 16-bit data paths throughout, however, the multiplexed external bus can op-

erate in an 8-bit narrow mode so single 8-bit wide memory can be interfaced for lower cost systems.
