A42MX24-3PQG208I

Overview

The A42MX24-3PQG208I is a Field Programmable Gate Array (FPGA) from the Microchip A42MX24 series. It features 912 Logic Elements and supports up to 176 user-programmable I/O pins within a 208-pin PQFP package. The device operates at a nominal voltage of 5V, with a supply range of 4.75V to 5.25V. It is rated for an industrial temperature range of -40°C to +85°C. This component serves as a high-capacity single-chip ASIC alternative, integrating fast wide-decode circuitry and supporting mixed-voltage operation for core and I/Os.

Feature Summary

• Provides a single-chip solution capable of consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs.
• Supports mixed-voltage operation allowing independent selection of 5.0V or 3.3V for core and I/Os.
• Enables deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.

Applications

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

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the package type matches the required PCB footprint. Check current lifecycle status as MX family components may have discontinuation notices. Ensure ESD handling protocols are followed during assembly.

Selection Notes

Select this model when 912 LEs and 176 I/Os are required in a PQFP-208 form factor. Compare against A42MX16 for lower capacity needs or A42MX36 for higher density. Verify that the 5V core voltage aligns with system power rails. Consider the -3 speed grade performance requirements relative to design timing constraints.

Part Context

This part belongs to the Microchip A42MX family, which offers cost-effective 5V FPGA solutions. The family ranges from 3,000 to 54,000 system gates. The A42MX24 variant specifically targets applications requiring moderate logic density with high I/O counts, bridging the gap between smaller CPLDs and larger FPGAs.

Replacement Considerations

Direct substitutes include other variants within the A42MX24 series with different packages or temperature grades, such as A42MX24-PQ208A. For higher capacity, consider the A42MX36 series. Verify pin compatibility before substituting.
