8085AH/-1/-2
The 8085AH is a complete 8-bit parallel Central Processing Unit (CPU) implemented in N-channel, depletion load,
silicon gate technology (HMOS). Its instruction set is 100% software compatible with the 8080A microprocessor,
and it is designed to improve the present 8080A’s performance by higher system speed. Its high level of system
integration allows a minimum system of three IC’s [8085AH (CPU), 8156H (RAM/IO) and 8755A (EPROM/IO)]
while maintaining total system expandability. The 8085AH-2 and 8085AH-1 are faster versions of the 8085AH.
The 8085AH incorporates all of the features that the 8224 (clock generator) and 8228 (system controller)
provided for the 8080A, thereby offering a higher level of system integration.
The 8085AH uses a multiplexed data bus. The address is split between the 8-bit address bus and the 8-bit data
bus. The on-chip address latches of 8155H/8156H/8755A memory products allow a direct interface with the
8085AH.
