A42MX16-VQ100I

Overview

The A42MX16-VQ100I is a Flash-based Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 100-pin VQFP package. It provides 608 Logic Elements and supports up to 83 user-programmable I/O pins. The device operates with a minimum supply voltage of 4.5V and a maximum of 5.5V, suitable for mixed-voltage applications. It functions within a commercial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum clock frequency of 48.24 MHz and a configurable dual-port SRAM capacity of up to 2.5 kbits.

Feature Summary

• Flash-based non-volatile architecture enabling instant power-up operation without external configuration memory.
• Supports mixed-voltage core and I/O operations, including PCI-compliant interfaces.
• Features deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.
• Includes unique in-system diagnostic and verification capability via Silicon Explorer II.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interface implementations
• DSP and co-processor function consolidation

Procurement Notes

Verify the specific suffix 'VQ100I' against official Microchip documentation, as standard listings often utilize 'VQG100I' or 'VQFP100' designations. Confirm moisture sensitivity level and assembly site changes through recent Product Change Notifications (PCNs). Ensure compatibility with required operating voltage ranges before procurement.

Selection Notes

Select this component for designs requiring immediate power-up functionality without boot ROMs. Compare against CPLD alternatives for higher density needs. Verify that the 100-pin VQFP footprint fits the PCB layout constraints. Check if the 48.24 MHz performance meets system timing requirements compared to faster variants in the MX family.

Part Context

This part belongs to the A42MX16 series within the broader MX FPGA family. It serves as a single-chip ASIC alternative, consolidating logic previously implemented in multiple PALs, CPLDs, or FPGAs. The series offers high capacity ranging from 3,000 to 54,000 system gates across various packages.

Replacement Considerations

Direct substitutes include A42MX16-2VQG100I and A42MX16-VQG100A. Verify package compatibility and temperature grade differences when selecting these alternatives.
