General Description

Introduction

The MC68HC908AS60 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCU). The M68HC08 Family is based on the customer-specified integrated circuit (CSIC) design strategy. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

Features

Features of the MC68HC908AS60 include:

• High-performance M68HC08 architecture

• 8.4-MHz internal bus frequency

• 60 Kbytes of FLASH electrically erasable read-only memory (FLASH)

• FLASH data security(1)

• 1 Kbyte of on-chip electrically erasable programmable read-only memory (EEPROM) with security option

• 2 Kbytes of on-chip random-access memory (RAM)

• Clock generator module (CGM)

• Serial peripheral interface module (SPI)

• Serial communications interface module (SCI)

• 8-bit, 15-channel analog-to-digital converter (ADC-15)

• 16-bit, 6-channel timer interface module (TIMA-6)

• Modulo timer (TIM)

• SAE J1850 byte data link controller digital module (BDLC-D)
