The MC68HC05B6 microcomputer (MCU) is a member of Freescale’s MC68HC05 family of
low-cost single chip microcomputers. This 8-bit MCU contains an on-chip oscillator, CPU, RAM,
ROM, EEPROM, A/D converter, pulse length modulated outputs, I/O, serial communications
interface, programmable timer system and watchdog. The fully static design allows operation at
frequencies down to dc to further reduce the already low power consumption to a few micro-amps.
