The MC68HC05X4 with on-board controller area network (CAN) module is designed around the industry standard M68HC05 CPU core with its familiar and efficient instruction set. The Motorola CAN module (MCAN) is complete with line interface circuitry, comprising output drivers, input comparators and a VDD/2 generator. The module can handle all the communication transactions flowing across a serial bus structure with minimal CPU intervention. Other features of the device include a 16-bit programmable timer, a 15-stage multi-purpose core timer and a computer operating properly (COP) watchdog timer. The MC68HC05X4 has two modes of operation, namely single chip and bootloader mode.
