A42MX16-PQG100A

Overview

The A42MX16-PQG100A is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a PQFP-100 package. It features 608 Logic Elements and approximately 24,000 system gates. The device supports mixed-voltage operation with supply voltages ranging from 4.5V to 5.5V. It includes 83 user-programmable I/O pins and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Single-chip ASIC alternative integrating high-capacity logic resources
• Supports mixed-voltage core and I/O operation for PCI-compliant interfaces
• Enables deterministic timing through user-controllable delay paths
• Facilitates design consolidation by replacing multiple PALs, CPLDs, or FPGAs

Applications

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

Procurement Notes

Verify the manufacturer designation on the component marking, as the product lineage originated from Microsemi before acquisition by Microchip Technology. Confirm that the specific ordering suffix corresponds to the required temperature grade and package variant. Ensure compatibility with the intended voltage levels and pin configurations prior to integration into the final assembly process.

Selection Notes

Select this model when a single-chip solution is required to replace legacy programmable logic devices such as PALs or CPLDs. The device is suitable for applications demanding mixed-voltage I/O capabilities and deterministic timing control. Consider the 100-pin QFP package constraints and the specific gate count requirements relative to the target logic complexity.

Part Context

This component belongs to the 40MX and 42MX FPGA families, which are designed as cost-effective, high-performance alternatives to standard ASICs. These devices consolidate logic functions typically distributed across multiple chips, thereby reducing board space and development cycles while maintaining high system performance standards.
