A42MX16-PQ160M

Overview

The A42MX16-PQ160M is a Field Programmable Gate Array (FPGA) belonging to the Microchip MX family. It features 608 Logic Elements and approximately 24,000 system gates. The device provides 125 user-programmable I/O pins and operates within a supply voltage range of 4.5 V to 5.5 V. It supports mixed-voltage operation for core and I/Os, including PCI-compliant levels. The component is housed in a PQFP-160 surface-mount package and is rated for an operating temperature range from -40°C to +125°C.

Feature Summary

• High-capacity single-chip ASIC alternative with up to 2.5 kbits of configurable dual-port SRAM
• Fast wide-decode circuitry supporting up to 35-bit address decoding
• Mixed-voltage operation capability allowing 5.0V or 3.3V core and I/O configurations
• Supports up to 100% resource utilization and 100% pin locking

Applications

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

Procurement Notes

Verify the specific suffix 'M' against official Microchip documentation to confirm if it denotes a military-grade qualification or specific packaging variant. Check current product status as some MX family members have reached end-of-life. Confirm moisture sensitivity level and reflow soldering profiles prior to assembly.

Selection Notes

Select this model when a high-performance 5V FPGA solution is required to replace multiple PALs, CPLDs, or FPGAs. Ensure the design utilizes the available 125 I/Os and fits within the 608 LE capacity. Verify that the PQFP-160 package dimensions meet the PCB layout requirements and that the thermal characteristics support the intended operating environment.

Part Context

This component is part of the Microchip MX FPGA family, which offers cost-effective design solutions at 5V. The family integrates logic typically implemented in multiple discrete devices, shortening system design cycles. The A42MX16 variant specifically targets applications requiring moderate gate counts with fast access times and deterministic timing.
