8-BIT HCMOS MICROCOMPUTER UNITS
The MC68HC04P2 and MC68HC04P3 HCMOS microcomputer units
(MCUs) are members of the M68HC04 Family of very low-cost single-
chip microcomputers. These 8-bit microcomputers contain a CPU, on-
chip CLOCK, ROM, RAM, I/O, and TIMER. They are designed for the
user who needs an economical microcomputer with the proven
capabilities of the M6800-based instruction set. The following are some
of the hardware and software highlights of the MC68HC04P2 and
M C68H C04P3 microcomputers.
