A42MX16-3PQ100I

Overview

The A42MX16-3PQ100I is a field-programmable gate array from the Microchip MX family, housed in a PQFP-100 package. It provides 295 configurable logic blocks and approximately 2,000 system gates. The device supports mixed-voltage operation with supply ranges of 4.5 V to 5.5 V for 5V core/I/O configurations or 3.0 V to 3.6 V for 3.3V configurations. It features 83 user-programmable I/O pins and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports mixed-voltage operation for both 5.0V and 3.3V core and I/O domains
• Provides deterministic, user-controllable timing characteristics
• Enables 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 speed grade suffix against official datasheets, as variations exist within the MX family. Confirm moisture sensitivity level requirements for surface-mount assembly processes. Ensure compatibility with existing design tools and programming hardware before procurement.

Selection Notes

Select this component for applications requiring high-density logic consolidation in a single-chip solution. Compare CLB counts and I/O availability against alternative FPGA families. Verify that the PQFP-100 footprint aligns with the target PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the A42MX series, which serves as a high-capacity single-chip ASIC alternative. The MX family integrates fast wide-decode circuitry and configurable dual-port SRAM to replace multiple discrete logic components, reducing board space and development cycles.

Replacement Considerations

Direct substitutes include other variants within the A42MX16 series, such as A42MX16-PQ100I or A42MX16-TQ100I, depending on package preference. Cross-family replacements require verification of equivalent logic density and I/O pin counts.
