A42MX24-PQ208M

Overview

The A42MX24-PQ208M is a high-capacity Field Programmable Gate Array (FPGA) belonging to the Microchip MX family. It provides 912 Logic Elements and supports up to 176 user-programmable I/O pins within a PQFP-208 package. The device operates at a nominal voltage of 5 V, with a supply range from 4.5 V to 5.5 V. It features an industrial temperature rating spanning from -40°C to +125°C. This component serves as a single-chip ASIC alternative, integrating fast wide-decode circuitry and supporting deterministic timing for complex logic applications.

Feature Summary

• Single-chip ASIC alternative consolidating multiple PALS, CPLDs, and FPGAs
• Deterministic, user-controllable timing with up to 100% resource utilization
• Mixed-voltage operation capability with PCI-compliant I/Os
• 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 'M' against official Microchip documentation, as standard listings often utilize suffixes like 'A' or 'I'. Confirm current lifecycle status, as many MX family parts are obsolete. Ensure compatibility with existing PCB footprints for the PQFP-208 package before procurement.

Selection Notes

Select this model for designs requiring 5V core voltage and robust industrial temperature performance. Compare logic density requirements against other MX variants to ensure optimal cost-performance balance. Verify that the 176 I/O count meets interface needs without excessive pin locking constraints.

Part Context

This part belongs to the 40MX and 42MX FPGA families, which offer system gates ranging from 3,000 to 54,000. These devices are designed to replace discrete logic solutions in automotive, industrial, and aerospace applications, providing high reliability and mixed-voltage operation capabilities.

Replacement Considerations

Check for direct substitutes within the same MX family, such as the A42MX24-PQ208A or A42MX24-2PQG208, ensuring package and speed grade compatibility. Verify if newer Microchip FPGA families offer functional equivalents with improved availability.
