A42MX24-PQG208

Overview

The A42MX24-PQG208 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, housed in a 208-pin PQFP package. It provides 912 Logic Elements and supports up to 176 user-programmable I/O pins. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a nominal operating voltage of 5 V. It is rated for an industrial temperature range of -40°C to +85°C. The architecture includes fast wide-decode circuitry and deterministic timing characteristics suitable for high-performance logic applications.

Feature Summary

• Supports mixed-voltage operation for both core and I/Os, enabling compatibility with 3.3V and 5.0V systems.
• Features deterministic, user-controllable timing to ensure predictable signal propagation delays.
• Includes unique in-system diagnostic capability utilizing Silicon Explorer II technology.

Applications

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

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified agents. Confirm that the specific part number matches the required package type and temperature grade. Check for recent Product Change Notifications regarding manufacturing site updates or assembly changes. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate that the source documentation aligns with the official datasheet specifications.

Selection Notes

Select this model when a 5V-only supply is available and a 208-pin surface-mount package is required. Compare against other MX family members if lower gate counts or different I/O densities suffice. Consider alternative packages such as BGA or QFN if board space constraints differ. Verify that the 912 LE capacity meets the design complexity without excessive resource utilization. Ensure the operating temperature range aligns with the final system environment requirements.

Part Context

This component belongs to the Microchip Actel MX FPGA family, which serves as a single-chip ASIC alternative. The series is designed to consolidate logic previously implemented in multiple PALs, CPLDs, and FPGAs. It offers a cost-effective solution for designs requiring high performance and shortened development cycles. The family supports various package options to accommodate different pin count and form factor needs.

Replacement Considerations

Direct replacements within the same package include other variants from the A42MX24 series, such as the A42MX24-PQ208A, provided the temperature grade and suffix specifications match. Cross-family migration to newer Microchip FPGA architectures requires significant redesign. Verify pinout compatibility before substituting with similar devices from other manufacturers.
