A42MX16-PQ100I

Overview

The A42MX16-PQ100I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a PQFP-100 surface-mount package. It contains 608 Logic Elements and approximately 24,000 system gates. The device supports mixed-voltage operation with a core voltage range of 3.3V to 5.5V and provides 83 user-programmable I/O pins. It operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, compatible with 3.3V and 5.0V standards.
• Features deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II technology.

Applications

• High-speed controllers
• Address decoding logic
• Peripheral bus interfaces

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C). Confirm the PQFP-100 package type matches the design footprint. Check current availability status as lead times may vary for this component series.

Selection Notes

Select this model when an ASIC alternative is needed for designs requiring up to 24,000 system gates. Ensure the application requires mixed-voltage support and fits within the 83 I/O constraint of the 100-pin package.

Part Context

This part belongs to the Microchip 40MX and 42MX FPGA families. These devices are designed to consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs into a single chip, reducing board space and development time.

Replacement Considerations

Compatible variants within the same package include A42MX16-PQ100A (commercial grade) and A42MX16-VQG100A (VQFP package). Verify temperature ratings before substitution.
