The MC68HC05X16 microcomputer (MCU) is a member of Motorola’s MC68HC05 family of low-cost single chip microcomputers. This 8-bit MCU contains an on-board controller area network module (MCAN), complete with interface circuitry, comprising output drivers, input comparators and a VDD/2 generator. In addition, the device 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, reducing power consumption to a few micro-amps.
