Overview
The MD80C88-2/B is a microprocessor belonging to the Intel 8088 family, manufactured by Intersil. It features an 8-bit external data bus and a 16-bit internal architecture, operating at a maximum clock frequency of 8 MHz with a 5V supply voltage. The device supports direct addressing of up to 1 Mbyte of memory and offers software compatibility with the 8086 CPU. It is housed in a 40-pin PDIP package and operates within an industrial temperature range of -40°C to +85°C.
Feature Summary
- Combines 8-bit external interface with 16-bit internal processing capabilities
- Provides direct software compatibility with 8086 applications
- Supports direct addressing of 1 Mbyte memory space
Applications
- Industrial control systems requiring 8-bit I/O compatibility
- Legacy computing hardware upgrades
- Embedded systems utilizing 8086-compatible instruction sets
Procurement Notes
Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific suffix matches the required package and temperature grade. Check for obsolescence status as this component may be discontinued. Ensure environmental compliance requirements align with project specifications before procurement.
Selection Notes
Select this processor when designing systems that require 8086 software compatibility but need an 8-bit external data bus to reduce system cost. Consider the 40-pin DIP package for through-hole mounting needs. Evaluate thermal management requirements for the specified industrial temperature range during system design.
Part Context
This component is part of the broader 8088 microprocessor lineage originally developed by Intel. Intersil produced variants under license, maintaining architectural consistency with the original specification. The MD80C88-2/B represents a commercial/industrial grade version within this family, sharing functional characteristics with other 8088 derivatives while differing in packaging and operational limits.
Replacement Considerations
Compatible substitutes include the P8088-2 from Intel and the IP80C88-2 from Renesas/Intersil. Verify pinout compatibility and electrical specifications before substitution. Ensure the replacement part meets the same temperature and voltage requirements.
