General Description
1.2 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.
