Chapter 1
General Description
1.1 Introduction
The MC68HC908GR16A 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
Features of the CPU08
1.2.1 Standard Features
Features 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 1-MHz to 8-MHz 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
Low-power design; fully static with stop and wait modes
Standard low-power modes of operation:
Wait mode
Stop mode
Master reset pin and power-on reset (POR)
16 Kbytes of on-chip FLASH memory
1 Kbyte of on-chip random-access memory (RAM)
406 bytes of FLASH programming routines read-only memory (ROM)
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the FLASH difficult for
unauthorized users.
