A42MX16-PQ160A

Overview

The A42MX16-PQ160A is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a PQFP-160 package. It features 608 Logic Elements and approximately 24,000 system gates. The device supports mixed-voltage operation with core and I/O voltages of 5.0V or 3.3V, including PCI-compliant I/Os. It offers up to 125 user-programmable I/O pins and includes configurable dual-port SRAM. The maximum clock frequency is specified at 48.24 MHz for this specific speed grade, with a CLB delay of 3.72 ns.

Feature Summary

• Single-chip ASIC alternative integrating logic previously requiring multiple PALs, CPLDs, or FPGAs
• Mixed-voltage operation capability supporting both 5.0V and 3.3V core and I/O configurations
• Deterministic, user-controllable timing with up to 100% resource utilization and pin locking
• 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 exact suffix against official Microchip documentation to confirm temperature range and speed grade. Confirm current production status as some variants may be discontinued. Check for RoHS compliance and moisture sensitivity level requirements during storage and handling.

Selection Notes

Select based on required I/O count and voltage levels. Ensure the PQFP-160 package fits the PCB footprint. Compare gate counts and SRAM needs against other MX family members like A42MX16-VQG100A if space constraints differ.

Part Context

Part of the 40MX and 42MX FPGA families designed for high-capacity applications. These devices serve as cost-effective solutions for consolidating complex logic designs into single chips, offering performance comparable to higher-cost ASICs while maintaining programmability.

Replacement Considerations

Check for direct substitutes within the A42MX16 series with different packages such as VQG100 or CQ172. Verify compatibility with existing design tools and programming cables.
