Features and Applications

The MC68HC705 is a member of the low-cost, high-performance M68HC05 Family of 8-bit microcontroller units (MCU).

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.


  • M68HC05 central processor unit (CPU)
  • On-chip oscillator with crystal/ceramic resonator
  • Memory-mapped input/output (I/O)
  • Selectable memory configurations
  • Selectable programmable and/or non-programmable
  • computer Operating properly (COP) watchdog timers
  • Selectable port B external interrupt capability
  • Clock monitor
  • High current drive on pin C7 (PC7)
  • 24 bidirectional I/O lines and 7 input-only lines
  • Serial communications interface (SCI) system
  • Serial peripheral interface (SPI) system
  • Bootstrap capability
  • Power-saving stop, wait, and data-retention modes
  • Single 3.0-volt to 5.5-volt supply (2-volt data-retention mode)
