Product Summary

The MC68HC705H12CFN is an 8-bit microcontroller unit (MCU). The MC68HC705H12CFN is an enhanced, high-speed version of the MC68HC705C8A. The MC68HC705H12CFN 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.
