A42MX16-2VQ100I

Overview

The A42MX16-2VQ100I is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin VQFP package. It provides 24,000 system gates and 608 logic elements with 83 user-programmable I/O pins. The device operates at a minimum supply voltage of 4.5 V and a maximum of 5.5 V, supporting mixed-voltage core and I/O configurations. It functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Single-chip ASIC alternative integrating high-capacity programmable logic
• Mixed-voltage operation capability for 5.0V or 3.3V core and I/Os
• Supports up to 100% resource utilization and pin locking
• Includes unique in-system diagnostic and verification capabilities

Applications

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

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the package type matches the 100-pin VQFP specification. Ensure compliance with RoHS directives and check for any export control classifications such as ECCN 3A991D before procurement.

Selection Notes

Select this component when a cost-effective single-chip solution replaces multiple PALs, CPLDs, or FPGAs. It is suitable for designs requiring deterministic timing and mixed-voltage compatibility. Consider the 24K gate capacity and 83 I/O count against project requirements.

Part Context

This part belongs to the A42MX16 series within the broader 40MX and 42MX FPGA families. These devices are designed to consolidate logic functions while shortening development cycles. The series offers high performance with features like fast wide-decode circuitry and configurable dual-port SRAM options.

Replacement Considerations

Check for direct substitutes within the same MX family, such as the A42MX16-VQG100I, noting that package variations may exist. Verify if older revisions or different suffixes offer equivalent electrical characteristics and thermal ratings.
