MC68HC908GT16 Datasheet, PDF (34/412 Pages) Motorola, Inc – Microcontrollers

General Description
1.2 Introduction
The MC68HC908GT16 is a member of the low-cost, high-performance
M68HC08 Family of 8-bit microcontroller units (MCUs). 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.
All references to the MC68HC908GT16 in this data book apply equally
to the MC68HC908GT8, unless otherwise stated.
1.3 Features
For convenience, features have been organized to reflect:
• Standard features of the MC68HC908GT16/MC68HC908GT8
• Features of the CPU08
1.3.1 Standard Features of the MC68HC908GT16/MC68HC908GT8
• High-performance M68HC08 architecture optimized for
C-compilers
• Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
• 8-MHz internal bus frequency
• Internal oscillator requiring no external components:
– Software selectable bus frequencies
– ±25 percent accuracy with trim capability to ±4 percent
– Clock monitor
– Option to allow use of external clock source or external
crystal/ceramic resonator
• FLASH program memory security⁽¹⁾
1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
