Freescale Semiconductor, Inc.
General Description
1.2 Introduction
The MC68HC908GP32 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.
1.3 Features
For convenience, features have been organized to reflect:
• Standard features of the MC68HC908GP32
• Features of the CPU08
1.3.1 Standard Features of the MC68HC908GP32
• High-performance M68HC08 architecture optimized for
C-compilers
• Fully upward-compatible object code with M6805, M146805, and
M68HC05 Families
• 8-MHz internal bus frequency
• FLASH program memory security¹
• On-chip programming firmware for use with host personal
computer which does not require high voltage for entry
• In-system programming
• System protection features:
– Optional computer operating properly (COP) reset
– Low-voltage detection with optional reset and selectable trip
points for 3.0-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.
