A42MX36-2PQ208

Overview

The A42MX36-2PQ208 is a high-performance Field Programmable Gate Array (FPGA) from the MX family, manufactured by Microchip Technology. It features 54,000 system gates and 2,438 Configurable Logic Blocks (CLBs). The device supports up to 2.5 kbits of configurable dual-port SRAM and offers up to 176 user-programmable I/O pins. It operates within a supply voltage range of 3V to 3.6V or 4.75V to 5.25V. The component is housed in a 208-BFQFP package with dimensions of 28x28 mm and is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Provides single-chip ASIC alternative capabilities with high gate density and deterministic timing.
• Supports mixed-voltage operation allowing flexible integration of 5.0V and 3.3V core and I/O standards.
• Includes unique in-system diagnostic and verification capability through Silicon Explorer II technology.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Consolidation of logic previously implemented in multiple PALs, CPLDs, and FPGAs

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm temperature grade and package variations. Note that certain variants within the A42MX36 series may have reached end-of-life status; check current product availability and lifecycle notices before finalizing procurement plans.

Selection Notes

Select this model when requiring approximately 54,000 system gates with a 208-pin QFP footprint. Ensure the design utilizes the specified 3V or 5V supply rails compatible with the -2 speed grade. Confirm pin-locking requirements are met given the 176 available I/Os.

Part Context

This component belongs to the Microsemi/Microchip MX FPGA family, designed as a cost-effective solution for replacing complex discrete logic. The A42MX36 variant specifically targets applications needing moderate capacity with high performance, bridging the gap between smaller CPLDs and larger FPGAs.

Replacement Considerations

Direct replacements include other A42MX36 variants such as A42MX36-2PQG208 or A42MX36-1PQG208B, provided the speed grade and package type match. Verify if industrial or military temperature grades are required instead of the commercial grade offered here.
