Product Summary

The M80C85AH is a complete 8-bit CMOS microprocessor. It is designed with higher processing speed (max.5 MHz) and lower power consumption compared with it and power down mode is provided, thereby offering a high level of system integration. The M80C85AH uses a multiplexed address/data bus. The address is split between the 8-bit address bus and the 8-bit data bus. The on-chip address latch : of a MSM81C55-5 memory product allows a direct interface with the M80C85AH.
