A42MX16-3PQG100I

Overview

The A42MX16-3PQG100I is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 24,000 system gates and 83 user-programmable I/O pins housed in a 100-PQFP package. The device operates on a single 5V supply voltage with a maximum operating frequency of 135 MHz. It supports commercial temperature ranges and includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.

Feature Summary

• Single-chip ASIC alternative providing high performance logic consolidation
• Supports mixed-voltage operation with PCI-compliant I/Os
• Features deterministic, user-controllable timing and pin locking
• Includes unique in-system diagnostic capability via Silicon Explorer II

Applications

• High-speed controllers
• Address decoding circuits
• Peripheral bus interfaces
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix '3PQG100I' against official Microchip documentation to confirm the exact speed grade and package variant. Ensure compatibility with existing PCB footprints for the PQFP-100 form factor. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process before ordering.

Selection Notes

Select this component when a cost-effective 5V FPGA solution is required to replace multiple PALs or CPLDs. Consider the 24,000 gate capacity and 83 I/O count for moderate complexity designs. Verify that the 135 MHz performance meets your timing constraints and that the PQFP package fits your board space limitations.

Part Context

This part belongs to the A42MX16 family within the broader MX FPGA portfolio. It shares architectural similarities with other devices in the 40MX and 42MX families, offering similar feature sets but varying in gate counts and I/O configurations. It serves as a direct upgrade path for legacy programmable logic designs requiring higher density.

Replacement Considerations

Direct substitutes include other variants within the A42MX16 family such as A42MX16-VQG100A or A42MX16-2VQG100I, provided the package type and speed grade are compatible. Cross-referencing with the A40MX series may be necessary if lower gate counts suffice.
