MC68HC705J2CP数据手册恩XP中文资料规格书

描述 Description

The MC68HC705J2 is a member of the low-cost, high-performance M68HC05 Family of 8-bit microcontroller units (MCUs). The high-density, complementary metal-oxide semiconductor (HCMOS) M68HC05 Family is based on the customer-specified integrated circuit (CSIC) design strategy. All MCUs in the family use the popular M68HC05 central processor unit (CPU) and are available with a
variety of subsystems, memory sizes and types, and package types.
