A42MX36-1PQG208

Overview

The A42MX36-1PQG208 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, housed in a 208-BFQFP package. It features 54,000 system gates and 176 I/O pins. The device includes 2,438 Configurable Logic Blocks (CLBs) with a maximum combinational delay of 2.32 ns. It supports supply voltages of 3V to 3.6V and 4.75V to 5.25V. The component operates within a temperature range of 0°C to 70°C and contains 2,560 bits of embedded RAM.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs.
• Supports mixed-voltage operation for core and I/Os, including PCI-compliant interfaces.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking.

Applications

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

Procurement Notes

Verify end-of-life status carefully, as official notices indicate obsolescence dates around mid-2025. Confirm RoHS compliance and moisture sensitivity level (MSL 3) before procurement. Check for assembly site changes documented in recent PCNs. Ensure final design can accommodate the specified operating voltage ranges and thermal constraints.

Selection Notes

Select this model for designs requiring high gate density in a QFP package without BGA complexity. Compare against A42MX36 variants with different speed grades or industrial temperature ratings if environmental conditions exceed commercial limits. Verify that the 208-pin footprint matches the PCB layout requirements.

Part Context

This part belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, designed as cost-effective solutions at 5V. These devices consolidate logic from multiple programmable chips into a single chip, offering high performance and shortened development cycles compared to discrete logic implementations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider reviewing the A42MX36 family datasheet for variants with updated software support or different temperature grades, such as the -I suffix for industrial range, though specific cross-references require manufacturer validation.
