MC68HC08AB16A Datasheet, PDF (30/380 Pages) Motorola, Inc – HCMOS Microcontroller Unit

Freescale Semiconductor, Inc.
General Description
1.2 Introduction
The MC68HC08AB16A 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.

Features of the MC68HC08AB16A 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 MC68HC08AB16
• 8-MHz internal bus frequency
• 16K-bytes user ROM memory with security¹ feature
• 512 bytes of on-chip EEPROM with security feature
• 512 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, Motorola’s strategy is to make reading or
copying the ROM difficult for unauthorized users.
