A42MX09-2PQG160I

Overview

The A42MX09-2PQG160I is a high-capacity Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 336 Configurable Logic Blocks (CLBs), equivalent to 14,000 system gates, and provides up to 104 user-programmable I/O pins. The device supports mixed-voltage operation with core voltages of 3V to 3.6V and I/O voltages of 4.75V to 5.25V. It is housed in a 160-pin Plastic Quad Flat Package (PQFP) with dimensions of 28x28 mm. The component operates within a commercial temperature range of 0°C to 70°C and includes up to 2.5 kbits of configurable dual-port SRAM for embedded memory applications.

Feature Summary

• Supports mixed-voltage operation allowing independent selection of 5.0V or 3.3V for core and I/O supplies, ensuring PCI compliance.

Applications

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

Procurement Notes

Verify the specific suffix '2' against official datasheets to confirm performance grade and voltage specifications, as variations exist within the MX family. Confirm RoHS compliance status, as some variants may differ. Check for End-of-Life notifications or Product Change Notices regarding assembly sites and software updates before finalizing procurement plans.

Selection Notes

Select this model when a cost-effective single-chip solution is required to replace multiple PALs, CPLDs, or FPGAs. Ensure the design utilizes the deterministic timing and 100% pin locking capabilities available in the MX architecture. Verify that the 160-PQFP package fits the board layout constraints and that the commercial temperature range meets the operational environment requirements.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, which are known for high performance and ease of integration. These devices consolidate logic typically implemented in multiple discrete components, shortening development cycles. The A42MX09 variant specifically targets applications requiring moderate gate counts with significant I/O flexibility and embedded memory resources.

Replacement Considerations

Direct substitutes include other variants within the A42MX09 series such as A42MX09-1PQG160I or A42MX09-FPQG160I, depending on the required speed grade and temperature rating. Cross-family migration to newer Microchip PolarFire or IGLOO2 devices may be necessary for long-term supply assurance, though pinouts and functionality will differ significantly.
