General Description
1.1 Introduction
The MC68HC908JW32 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
Features of the MC68HC908JW32 include:
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the FLASH/ROM
Freescale Semiconductor
difficult for unauthorized users.
