General Description
1.2 Introduction
The MC68HC908AB32 is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCUs) with embedded
EEPROM for user data storage. 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.
1.3 Features
Technical Data
30
Features of the MC68HC908AB32 include the following:
⢠High-performance M68HC08 architecture
⢠Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
⢠Memory map and pin functions compatible with MC68HC08AB32
and MC68HC08AB16
⢠8-MHz internal bus frequency
⢠32K-bytes user program FLASH memory with security1 feature
⢠512 bytes of on-chip EEPROM with security feature
⢠1K-byte of on-chip RAM
⢠Clock generator module (CGM)
⢠Two 16-bit, 4-channel timer interface modules (TIMA and TIMB)
with selectable input capture, output compare, and PWM
capability on each channel
⢠Programmable interrupt timer (PIT)
⢠Serial peripheral interface module (SPI)
⢠Serial communications interface module (SCI)
⢠8-channel. 8-bit analog-to-digital converter (ADC)
⢠Low-power design (fully static with STOP and WAIT modes)
⢠Master reset pin and power-on reset
1. No security feature is absolutely secure. However, Freescaleâs strategy is to make reading or
copying the FLASH difficult for unauthorized users.
