on the MC68HC908AS60A/AZ60A
By Adeela Gill and Kazue Kikuchi
Transportation and Standard Products Group
Austin, Texas
Introduction
Freescale has released two new microcontrollers (MCU), the
MC68HC908AS60A (AS60A) and the MC68HC908AZ60A (AZ60A), as
new products in the M68HC08 Family of low-cost, high-performance
devices.
The AS60A and AZ60A offer many features, including:
• 8.4-MHz internal bus frequency
• 60 Kbytes of FLASH memory
• FLASH data security
• One Kbyte of EEPROM with security option
• Two Kbytes of on-chip RAM
• On-chip charge pump
This application note explains how to use the FLASH and EEPROM on
the MC68HC908AS60A/AZ60A and provides example software for
program and erase operations. These algorithms are written in
M68HC08 assembly code.
