General Description
Introduction
The MC68HC705C8A, an enhanced version of the MC68HC705C8, is a member of the low-cost, high-performance M68HC05 Family of 8-bit microcontroller units MCU. The MC68HSC705C8A, introduced in Appendix A. MC68HSC705C8A, is an enhanced, high-speed version of the MC68HC705C8A. The M68HC05 Family is based on the customer-specified integrated circuit CSIC design strategy. All MCUs in the family use the M68HC05 central processor unit CPU and are available with a variety of subsystems, memory sizes and types, and package types.
