8405201XA

Overview

The Intersil 8405201XA is a CMOS 16-bit microprocessor based on the 80C86 architecture. It operates at a clock speed of 5 MHz and supports a 5V I/O voltage level. The component is housed in a 40-pin CERDIP package, also designated as CQCC44. It features an operating temperature range from -55°C to 125°C (TC). The device includes internal reset sequencing triggered by low-going transitions, sampling RDY signals near the end of machine states.

Feature Summary

• CMOS 16-bit microprocessor core
• Internal reset sequence generation
• RDY signal sampling capability

Applications

• Industrial control systems
• Military grade embedded applications
• High-temperature electronic environments

Procurement Notes

Verify the specific package variant, as sources list both CERDIP and CQCC44 designations for this part number. Confirm RoHS compliance status with the supplier, as some listings indicate non-compliance while others suggest availability. Ensure the operating temperature range meets the -55°C to 125°C requirement for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a 16-bit processing capability is required within a wide industrial or military temperature range. The 5 MHz speed suits legacy or specific timing-critical applications rather than high-performance computing. Consider the 40-pin ceramic DIP form factor for board space and thermal management requirements compatible with through-hole mounting.

Part Context

This microprocessor belongs to the 80C86 family produced by Intersil, now part of Renesas. It serves as a robust solution for demanding environments due to its CMOS construction and extended temperature rating. The device provides standard 16-bit processing functions with specific interface characteristics defined by the 80C86 architecture.

Replacement Considerations

Check for direct pin-compatible substitutes within the 80C86 family that may offer updated manufacturing processes. Verify if newer CMOS variants maintain the same 5V logic levels and package dimensions to ensure mechanical interchangeability without redesigning the host circuit board.
