A42MX36-1PQG208M

Overview

The A42MX36-1PQG208M is a Field Programmable Gate Array from the Microchip A42MX family, housed in a PQFP-208 package. It contains 2438 Configurable Logic Blocks (CLBs) and offers 36,000 system gates. The device supports mixed-voltage operation at 3.3 V or 5.0 V for core and I/Os, with a maximum operating voltage of 5.5 V. It features a maximum clock frequency of 48 MHz and a CLB-maximum combinational delay of 2.32 ns. The component operates within a temperature range of -55 °C to +125 °C and includes up to 2.5 kbits of configurable dual-port SRAM.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports mixed-voltage operation with PCI-compliant I/Os for flexible interface integration.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking.
• Includes unique in-system diagnostic and verification capabilities via Silicon Explorer II.

Applications

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

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm it denotes the military temperature grade (-55°C to +125°C). Confirm RoHS compliance status as datasheets may vary by revision. Check for End-of-Life (EOL) notices or Last Time Buy dates, as older Actel/Microsemi FPGA families often face obsolescence. Ensure supply chain sources are authorized distributors to avoid counterfeit components.

Selection Notes

Select this model when high performance at 5V is required alongside wide industrial or military temperature ranges. Compare against the 'I' suffix variant if only industrial temperature (-40°C to +85°C) is needed. Verify that the 208-pin PQFP package fits the PCB footprint constraints. Consider the 36,000 gate capacity relative to design complexity to ensure sufficient logic resources without excessive cost.

Part Context

This component belongs to the A42MX series, originally developed by Actel and acquired by Microsemi, now part of Microchip Technology. The series is designed as a high-capacity, single-chip solution for applications replacing complex discrete logic. The A42MX36 specifically targets designs needing substantial logic density with fast access times and robust radiation tolerance options available in ceramic packages.

Replacement Considerations

Publicly confirmed substitute part numbers for this specific configuration are not available in the provided data. Designers should consult Microchip's official lifecycle management tools for current obsolescence status and recommended migration paths to modern FPGA families.
