Section 1. General Description
1.1 Introduction
The MC68HC908GR16 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.
1.2 Features
For convenience, features have been organized to reflect:
• Standard features of the MC68HC908GR16
• Features of the CPU08
1.2.1 Standard Features of the MC68HC908GR16
Features of the MC68HC908GR16 include:
• High-performance M68HC08 architecture optimized for C-compilers
• Fully upward-compatible object code with M6805, M146805, and M68HC05
Families
• 8-MHz internal bus frequency
• Clock generation module supporting 32-kHz to 100-kHz crystals
• FLASH program memory security⁽¹⁾
• On-chip programming firmware for use with host personal computer which
does not require high voltage for entry
• In-system programming (ISP)
• System protection features:
– Optional computer operating properly (COP) reset
– Low-voltage detection with optional reset and selectable trip points for
3.3-V and 5.0-V operation
– Illegal opcode detection with reset
– Illegal address detection with reset
1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
