A42MX16-VQ100M

Overview

The A42MX16-VQ100M is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 24,000 system gates and 608 Logic Elements within a 100-pin VQFP package. The device supports dual voltage operation with a core supply of 3V to 3.6V and I/O supplies of 4.5V to 5.5V. It offers 83 user-programmable I/O pins and operates within an industrial temperature range of -55°C to +125°C. The component utilizes CMOS technology and is RoHS compliant.

Feature Summary

• Single-chip ASIC alternative providing high performance logic consolidation
• Mixed-voltage operation capability supporting both 3.3V and 5.0V domains
• Deterministic timing with user-controllable constraints for reliable design

Applications

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

Procurement Notes

Verify the specific suffix 'M' against the manufacturer's current datasheet DS2316 to confirm exact environmental ratings and packaging details. Ensure compatibility with existing PCB footprints for the 100-VQFP form factor. Confirm moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this model when designing systems requiring 24K system gates with mixed-voltage I/O support. The industrial temperature grade (-55°C to +125°C) suits harsh environments. Compare against the A42MX16-VQG100A if commercial grade suffices, or consider higher gate counts in the A42MX36 series for increased logic density.

Part Context

This component belongs to the Microchip 42MX FPGA family, which serves as a cost-effective solution for replacing multiple PALs, CPLDs, and FPGAs. The MX series is known for fast wide-decode circuitry and high resource utilization, allowing designers to consolidate complex logic into a single chip while shortening development cycles.

Replacement Considerations

The A42MX16-VQG100A is a verified substitute within the same package family, differing primarily in operating temperature range.
