8-BIT MICROPROCESSING UNIT (MPU)
The MC6800 is a monolithic 8-bit microprocessor forming the central
control function for Motorola’s M68~ family. Compatible with TTL, the
MC6B~, as with all M6800 system parts, requires only one + 5.O-volt
power supply, and no external TTL devices for bus interface.
The MC6800 is capable of addressing 64K bytes of memory with its
16-bit address lines. The 8-bit data bus is bidirectional as well as three-
state, making direct memory addressing and multiprocessing applica-
tions realizable.

This device contains circuitry to protect the
inputs against damage due to high static
voltages or electrical fields; however, it is ad-
vised that normal precautions be taken to
avoid application of any voltage higher than
maximum-rated voltages to this high-
impedance circuit. Reliability of operation is
