8-BIT MICROPROCESSOR UNIT
The MCl@05E2 Microprocessor Unit (MPU) belongs to the M6805
Family of Microcomputers. This 8-bit fully static and expandable
microprocessor contains a CPU, on-chip RAM, 1/0, and TIMER. It is a
low-power, low-cost processor designed for low-end to mid-range ap-
plications in the consumer, automotive, industrial, and communications
markets where very low power consumption constitutes an important
factor. The following are the major features of the MC146805E2 MPU:
