CD80C88

Microprocessors Overview

The CD80C88 is an 8-bit microprocessor manufactured by Harris Corporation, utilizing CMOS technology. It operates with a maximum clock frequency of 5 MHz and features a 20-bit address bus width alongside an 8-bit external data bus. The device is housed in a 40-pin Ceramic Dual In-Line Package (CDIP-40). It supports a supply voltage range from 4.75V to 5.25V and functions within an operating temperature range of -55°C to +125°C.

Microprocessors Feature Summary

• CMOS implementation using self-aligned silicon gate process for high performance
• Compatible with standard 8088 architecture interfaces
• Ceramic dual in-line packaging for robust environmental stability

Microprocessors Applications

• Industrial control systems requiring high thermal stability
• Military and aerospace embedded computing applications
• High-reliability data acquisition hardware

Microprocessors Procurement Notes

Verify the ceramic package variant against plastic DIP alternatives when sourcing replacements. Confirm RoHS compliance status as original Harris production may predate modern regulations. Ensure the specific suffix indicates the correct temperature grade for your operational environment before finalizing procurement orders.

Microprocessors Selection Notes

Select this component when industrial or military temperature ranges are mandatory. The ceramic package offers superior hermeticity compared to plastic variants. Consider the 5 MHz speed limit when designing timing-critical buses. Verify pin compatibility with existing PCB footprints designed for standard DIP-40 layouts.

Microprocessors Part Context

This part belongs to the Harris 80C88 family of microprocessors. It serves as the CMOS version of the classic Intel 8088 architecture. The CD prefix specifically denotes the ceramic dual in-line package construction. This distinguishes it from plastic DIP or surface mount equivalents in the same product line.
