A42MX36-3PQ208

Overview

The A42MX36-3PQ208 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 208-pin PQFP package. It features 1184 Configurable Logic Blocks (CLBs) and approximately 54,000 system gates. The device supports mixed-voltage operation with supply ranges of 3V to 3.6V for the core and 4.75V to 5.25V for I/Os. It includes up to 2.5 kbits of configurable dual-port SRAM and offers up to 202 user-programmable I/O pins. The maximum operating frequency is rated at 48 MHz, with a typical CLB combinational delay of 3.8 ns.

Feature Summary

• Single-chip ASIC alternative providing high performance logic consolidation
• Mixed-voltage operation capability supporting both 3.3V and 5.0V domains
• Integrated configurable dual-port SRAM for data storage and buffering
• Deterministic timing with user-controllable resource utilization

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Military and aerospace applications requiring HiRel certification

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential obsolescence risks within the MX family. Confirm specific speed grade suffixes and package variations against current datasheets before procurement. Check for recent Product Change Notifications regarding assembly sites or material compliance updates.

Selection Notes

Select this model when 54,000 system gates and 202 I/Os are required in a PQFP form factor. Ensure design requirements align with the 48 MHz maximum frequency and 3.8 ns CLB delay specifications. Consider mixed-voltage I/O needs if interfacing with both 3.3V and 5.0V peripherals.

Part Context

This part belongs to the Actel/Microchip 42MX FPGA family, known for non-volatile flash-based technology. It serves as a drop-in replacement for complex PALs, CPLDs, and older SRAM FPGAs. The MX series emphasizes low power consumption and instant-on capabilities compared to traditional volatile FPGA architectures.

Replacement Considerations

Direct pin-to-pin replacements may include other speed grades within the A42MX36 series, such as A42MX36-1PQ208 or A42MX36-2PQ208, depending on timing requirements. Verify electrical compatibility and package dimensions for any cross-reference.
