MCHC908LK24CFQE：68HC908LK24 系列12-32K 的Flash存储器，80pin QFP 封装

MCHC908LK24CFQE 是低成本、高性能的M68HC08系列8位微控制器单元（MCU）的成员之一。M68HC08系列基于专用集成电路（CSIC）设计策略。该系列的所有MCU均采用增强型M68HC08中央处理器（CPU08），并提供多种模块、内存大小和类型，以及多种封装形式。

The MCHC908LK24CFQE is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08 Family is based on the customer-specific integrated circuit (CSIC) design strategy. 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 packages.
