A42MX09-VQ100I

Overview

The A42MX09-VQ100I is a Field Programmable Gate Array (FPGA) from the MX series, manufactured by Microchip Technology. It features 336 Logic Elements and approximately 14,000 system gates. The device supports mixed-voltage operation with core supply voltages of 3V to 3.6V and I/O supply voltages of 4.75V to 5.25V. It is housed in a VQFP-100 package with 83 user-programmable I/O pins. The component operates within a commercial temperature range of -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Single-chip ASIC alternative offering high performance for logic consolidation
• Mixed-voltage operation capability supporting both 5.0V and 3.3V I/Os
• Deterministic, user-controllable timing with up to 100% pin locking

Applications

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

Procurement Notes

Verify the specific suffix 'VQ100I' against official Microchip documentation to confirm the VQFP-100 package and industrial temperature grade. Cross-reference the part number with current datasheets as legacy Actel/Microsemi products may have discontinuation notices or PCNs affecting availability and assembly sites.

Selection Notes

Select this model when a compact 100-pin solution is required for mid-density logic applications. Ensure design requirements align with the 3.3V/5V mixed-voltage I/O capabilities. Verify that the 336 LE capacity meets the design complexity before considering higher-gate variants like the A42MX16 or A42MX24.

Part Context

This component belongs to the 40MX and 42MX FPGA families originally developed by Actel and acquired by Microsemi, now Microchip Technology. These devices are designed to replace multiple PALs, CPLDs, and FPGAs in a single chip, providing a cost-effective solution for systems requiring moderate logic density and fast wide-decode circuitry.

Replacement Considerations
