Motorola 68000: Difference between revisions

Latest revision as of 05:01, 16 October 2024

The Motorola MC68000 (P/N 156-1445-00) is a 16-bit microprocessor monolithic integrated circuit with internal 32-bit architecture and buses, introduced in 1979.

It requires +5 V power only and came initially in 64-pin DIL packages. The external bus is asynchronous.

The 68000 has non-multiplexed data (16 bit) and address (24 bit) buses. The 68008 was a version with an 8-bit external data bus, initially available in a 48-pin DIL package.

The 68010 (1982) included minor improvements to support virtual memory and virtualization.

The data ALU is 16 bits wide.

Initial speed grades were 4, 6 and 8 MHz. Faster versions and CMOS implementations were available later, as were second-source versions.

The original 4 MHz Motorola 68000 CPU was added to the Tek parts inventory in March 1980 as P/N 156-1445-00, at a unit cost of $150 (~$560 in 2023 dollars).
