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:
1.2.1 Standard Features of the MC68HC908GR16
Features of the MC68HC908GR16 include:
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the FLASH difficult for
unauthorized users.
