MC68HC705 Datasheet PDF

●The MC68HC705C8ACFNE is a 8-bit high-performance Microcontroller Unit (MCU). The 68HC705C8a microcomputer (MCU) is a member of NXP"s M68HC05 family of single-chip microcomputers. This 8-bit MCU includes keyboard scanning logic, a high current pin, a COP watchdog timer and read-only (ROM) security feature. 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.
