A42MX16-2VQG100

Overview

The A42MX16-2VQG100 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin VQFP package. It provides 608 Logic Elements and approximately 24,000 system gates. The device supports mixed-voltage operation with supply voltage ranges of 3.3V (3.0V to 3.6V) and 5.0V (4.75V to 5.25V). It features 83 user-programmable I/O pins and operates within a commercial temperature range of 0°C to +70°C. The component exhibits Moisture Sensitivity Level 3.

Feature Summary

• Single-chip ASIC alternative consolidating logic from multiple PLAs, CPLDs, and FPGAs
• Mixed-voltage operation supporting both 5.0V and 3.3V core and I/O configurations
• 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 the specific suffix against official datasheets to confirm voltage and temperature ratings. Confirm RoHS compliance status for current production lots. Check manufacturer notifications regarding end-of-life or discontinuance, as older FPGA families may have limited availability or transitioned manufacturing sites.

Selection Notes

Select this model for designs requiring deterministic timing and high pin-locking capabilities. Ensure the application fits within the 608 LE capacity and 83 I/O limit. Verify that the required operating environment aligns with the commercial temperature grade (-40°C to +85°C is available in other variants, but this specific part is rated 0°C to +70°C).

Part Context

This component belongs to the A42MX16 series, which offers up to 24,000 system gates. The '2' suffix typically denotes a speed grade, while 'VQG100' specifies the 100-pin Very Thin Quad Flat Package. It serves as a drop-in replacement for complex discrete logic or smaller programmable devices in industrial and commercial applications.

Replacement Considerations

Direct functional substitutes include other parts within the A42MX16 family, such as the A42MX16-VQG100A, provided the temperature and speed grades match the design requirements. Cross-family migration to newer Actel or Microsemi FPGA architectures requires significant schematic and software re-verification.
