IP80C88

Microprocessors Overview

The IP80C88 is an 8-bit/16-bit microprocessor based on the 80C88 core, manufactured by Harris Corporation. It operates at a maximum clock frequency of 5 MHz with a single 5 V supply voltage. The device features a 20-bit address bus and an 8-bit external data bus, packaged in a 40-pin PDIP format. It supports an industrial operating temperature range from -40°C to +85°C.

Microprocessors Feature Summary

• CMOS technology implementation for low power consumption
• Compatible with standard 8088 instruction set architecture
• Supports through-hole mounting via dual in-line package

Microprocessors Applications

• Industrial control systems requiring 8088 compatibility
• Embedded applications utilizing CMOS microprocessors
• Legacy system maintenance and replacement

Microprocessors Procurement Notes

Verify component authenticity as the IP80C88 is listed as discontinued by major distributors such as Mouser. Confirm manufacturer origin, noting transitions between Harris, Intersil, and Renesas Electronics. Ensure the specific package variant matches design requirements before integration into legacy hardware projects.

Microprocessors Selection Notes

Select this component when maintaining systems designed around the 80C88 architecture. It serves as a direct CMOS replacement for older NMOS variants. Consider the 5 MHz speed limit and 40-pin DIP form factor against modern alternatives if new designs are feasible. Verify voltage tolerance and thermal specifications for the target environment.

Microprocessors Part Context

This part belongs to the Harris 80C88 family of microprocessors. It shares architectural similarities with other Harris parts like the IR80C88-2 but differs in clock speed and package type. The IP80C88 specifically denotes the 5 MHz version in the PDIP-40 package, distinct from higher-speed or ceramic carrier variants within the same product line.

Microprocessors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The component is marked as discontinued. Designers should evaluate functional equivalents from current manufacturers that support the 80C88 instruction set and physical pinout compatibility.
