INTRODUCTION
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 V_DD/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.
This data sheet is structured such that devices similar to the MC68HC05X16 are described in a
set of appendices (see Table 1-1).
