A42MX16-1VQ100I

Overview

The A42MX16-1VQ100I is a field-programmable gate array (FPGA) from the Microchip MX family, designed for high-capacity logic applications. It features 24,000 system gates and 608 logic elements within a 100-pin VQFP package. The device supports mixed-voltage operation with a core voltage of 3.3V and I/O voltages ranging from 4.5V to 5.5V. It provides 83 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C. The component utilizes flash-based non-volatile technology, eliminating the need for external configuration memory.

Feature Summary

• Flash-based non-volatile architecture enabling instant-on functionality without external configuration devices
• Mixed-voltage capability supporting both 3.3V core and 5.0V I/O interfaces for legacy compatibility
• Deterministic timing characteristics with user-controllable delays and pin locking capabilities

Applications

• High-speed controller implementations replacing complex programmable logic devices
• Peripheral bus interface bridging between different voltage domains
• Address decoding and control logic in industrial automation systems

Procurement Notes

Verify the specific suffix '1VQ100I' against the official Microchip datasheet DS2316 to confirm the exact speed grade and package variant. Ensure that the industrial temperature rating (-40°C to +85°C) aligns with your environmental requirements. Check for any recent Product Change Notifications regarding assembly sites or material composition updates before finalizing procurement.

Selection Notes

Select this component when a single-chip solution is required to consolidate multiple PALs, CPLDs, or FPGAs. It is suitable for designs needing deterministic timing and mixed-voltage I/O support. Consider alternative packages such as PQFP or CQFP if pin count or thermal constraints differ. Verify that the 24K gate capacity meets the logic density requirements of the target application.

Part Context

This part belongs to the A42MX16 series within the broader Microchip MX FPGA portfolio. The series offers scalable logic densities ranging from 3,000 to 54,000 system gates. The A42MX16 specifically targets mid-range applications requiring high performance and low power consumption. It serves as a direct replacement for older discrete logic families in embedded systems.

Replacement Considerations

Direct pin-compatible alternatives within the same package include other speed grades of the A42MX16 series, such as A42MX16-2VQ100I. For higher logic density, consider the A54SX16P series, though pinouts may vary. Always verify electrical specifications and timing parameters against the original design requirements when substituting.
