i 8-BIT MICROPROCESSING UNIT (MPU)
I 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 threestate, making direct memory addressing and multiprocessing applications realizable. q 8-Bit Parallel Processing
