Section 1. General Description
1.1 Introduction
The MC68HC08AS32A is a member of the low-cost, high-performance M68HC08
Family of 8-bit microcontroller units (MCUs). 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.
1.2 Features
Features of the MC68HC08AS32A include:
• High-performance M68HC08 architecture
• Fully upward-compatible object code with M6805, M146805, and M68HC05
Families
• 8.4-MHz internal bus frequency
• 32,256 bytes of read-only memory (ROM)
• ROM data security
• 512 bytes of on-chip electrically erasable programmable read-only memory
(EEPROM)
• 1024 bytes of on-chip random-access memory (RAM)
• Serial peripheral interface module (SPI)
• Serial communications interface module (SCI)
• 16-bit, 6-channel timer interface module (TIM)
• Clock generator module (CGM)
• 8-bit, 15-channel analog-to-digital converter module (ADC)
• SAE J1850 byte data link controller digital module (BDLC-D)
• System protection features:
– Computer operating properly (COP) with optional reset
– Low-voltage detection with optional reset
– Illegal opcode detection with optional reset
– Illegal address detection with optional reset
• Low-power design (fully static with stop and wait modes)
• Master reset pin and power-on reset
