80C88

CMOS 8-/16-Bit Microprocessor

DATASHEET

The Intersil 80C88 high performance 8-/16-bit CMOS CPU is

manufactured using a self-aligned silicon gate CMOS process

(Scaled SAJI IV). Two modes of operation, Minimum for small

systems and Maximum for larger applications such as

multiprocessing, allow user configuration to achieve the

highest performance level.

Full TTL compatibility (with the exception of CLOCK) and

industry-standard operation allow use of existing NMOS 8088

hardware and Intersil CMOS peripherals.

Complete software compatibility with the 80C86, 8086, and

8088 microprocessors allows use of existing software in new

designs.
