General Description
1.1 Introduction
The MC68HC908QY4 is a member of the low-cost, high-performance M68HC08 Family of 8-bit
microcontroller units (MCUs). The M68HC08 Family is a Complex Instruction Set Computer (CISC) with
a Von Neumann architecture. 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 include:
1. The oscillator frequency is guaranteed to ±5% over temperature and voltage range after trimming.
2. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or copying the FLASH difficult for
Freescale Semiconductor
unauthorized users.
