MC68HC705C8ACP Description

The M68HC05 Family of 8-bit microcontroller devices includes the upgraded MC68HC705C8ACP, which is a low-cost, high-performance variant of the MC68HC705C8 (MCU). An improved, faster variant of the MC68HC705C8A, the MC68HC705C8ACP is described in Appendix A. The customer-specified integrated circuit (CSIC) design approach is the foundation of the M68HC05 Family. All MCUs in the family employ the M68HC05 central processor unit (CPU) and are available with a number of subsystems, memory sizes and kinds, and package types.
