A42MX16-VQ100

Overview

The A42MX16-VQ100 is a Field Programmable Gate Array (FPGA) belonging to the Microchip MX family. It features 295 Configurable Logic Blocks (CLBs) and approximately 2,000 system gates. The device supports mixed-voltage operation with core and I/O voltages of 3.3V or 5.0V, ensuring PCI-compliant compatibility. It includes up to 2.5 kbits of configurable dual-port SRAM and offers deterministic timing with user-controllable delays. The component is available in a 100-pin VQFP package and supports commercial, industrial, automotive, and military temperature ranges.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Mixed-voltage operation supporting both 5.0V and 3.3V for core and I/Os
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• Integrated in-system diagnostic and verification capability via Silicon Explorer II

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets, as variations like -A or -M may indicate different speed grades or environmental certifications. Confirm moisture sensitivity level and reflow soldering profiles prior to assembly. Ensure the selected variant matches the required operating temperature range for the target application environment.

Selection Notes

Select this model for designs requiring high-density logic consolidation in a single chip. Consider the 2.5 kbits of embedded SRAM for buffer requirements. Verify that the 100-pin VQFP package fits the board layout constraints. Check if the specific speed grade meets the maximum clock frequency requirements of the design.

Part Context

This component is part of the Microsemi (now Microchip Technology) 40MX and 42MX FPGA families. These devices are designed as cost-effective solutions for replacing complex discrete logic. The family provides high performance while shortening system design cycles through full integration of logic, memory, and I/O capabilities on a single die.

Replacement Considerations

Direct replacements within the same package include other speed grades of the A42MX16 series, such as A42MX16-1VQ100 or A42MX16-2VQ100. Cross-family migration to Actel SmartFusion or IGLOO devices requires significant schematic and code redesign due to architectural differences.
