Motorola 6800: Difference between revisions

The Motorola 6800 is an 8-bit microprocessor introduced in 1974.

It requires a +5 V supply only (generating bias voltages on chip) and came initially in 40-pin DIL packages. The 6800 has non-multiplexed data (8 bit) and address (16 bit) buses, and requires an external non-overlapping two-phase 0.1 − 1 MHz clock (later versions from 1976 on up to 2 MHz).

The 6802, introduced in 1977, includes 128 bytes RAM and an internal clock oscillator. The 6808 is the same without RAM.
