8088 Datasheet PDF – 8-Bit HMOS Microprocessor – INTEL

Part Number: 8088

Function: 8-bit HMOS microprocessor, 5 MHz

Package: 40-Pin CERDIP Type

Manufacturer: Intel





The Intel 8088 is a high performance microprocessor implemented in N-channel, depletion load, silicon gate technology (HMOS-II), and packaged in a 40-pin CERDIP package. The processor has attributes of both 8-and 16-bit microprocessors. It is directly compatible with 8086 software and 8080/8085 hardware and peripherals. Processor initialization or start up is accomplished with activation (HIGH) of the RESET pin. The 8088 RESET is required to be HIGH for greater than four clock cycles.
