DATASHEET 80C88 FN2949 Rev.5.00 CMOS 8-/16-Bit Microprocessor Sep 28, 2017 The Intersil 80C88 high performance 8-/16-bit CMOS CPU is Features manufactured using a self-aligned silicon gate CMOS process Compatible with NMOS 8088 (Scaled SAJI IV). Two modes of operation, Minimum for small systems and Maximum for larger applications such as Direct software compatibility with 80C86, 8086, 8088 multiprocessing, allow user configuration to achieve the 8-bit data bus interface 16-bit internal architecture highest performance level. Completely static CMOS design Full TTL compatibility (with the exception of CLOCK) and - DC 5MHz (80C88) industry-standard operation allow use of existing NMOS 8088 - DC 8MHz (80C88-2) hardware and Intersil CMOS peripherals. Low power operation Complete software compatibility with the 80C86, 8086, and - ICCSB . 500A maximum 8088 microprocessors allows use of existing software in new designs. - ICCOP . 10mA/MHz maximum 1 MB of direct memory addressing capability Related Literature 24 operand addressing modes For a full list of related documents, visit our website Bit, byte, word, and block move operations - 80C88 product page 8-bit and 16-bit signed/unsigned arithmetic Bus-hold circuitry eliminates pull-up resistors Wide operating temperature ranges - C80C88 .0C to +70C - M80C88 .-55C to +125C Pb-free available (RoHS compliant) Ordering Information TEMPERATURE PART NUMBER PART PART NUMBER PART RANGE (5MHz) MARKING (8MHz) MARKING (C) PACKAGE PKG.
