A42MX24-2PQ208

Overview

The A42MX24-2PQ208 is a Field Programmable Gate Array (FPGA) from the Microchip MX family, designed as a single-chip ASIC alternative. It features 36,000 system gates and 912 Logic Elements within a 208-pin PQFP package. The device supports mixed-voltage operation with a core voltage of 5V and I/O voltages ranging from 3.3V to 5.5V. It operates within a commercial temperature range of 0°C to +70°C. Key specifications include up to 2.5 kbits of configurable dual-port SRAM and support for IEEE 1149.1 JTAG boundary scan testing.

Feature Summary

• Provides high-capacity logic density suitable for replacing multiple PALs, CPLDs, or FPGAs in a single chip.
• Supports deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.
• Enables mixed-voltage operation allowing flexible integration of 3.3V and 5.0V I/O standards.

Applications

• High-speed controllers and address decoding systems
• Peripheral bus interfaces and DSP co-processor functions
• Automotive applications requiring robust programmable logic

Procurement Notes

Verify component authenticity through authorized Microchip distributors due to potential counterfeit risks. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Check for recent Product Change Notifications regarding assembly site updates or software tool compatibility changes that may affect production readiness.

Selection Notes

Select this model when 36,000 system gates and 176 I/O pins are required in a PQFP-208 form factor. Ensure design requirements align with the 5V core voltage specification. Consider the -2 speed grade if specific timing constraints necessitate verification against the datasheet performance tables for clock-to-out delays.

Part Context

This component belongs to the Microsemi/Microchip 40MX and 42MX FPGA families, which were acquired by Microchip Technology. These devices are positioned as cost-effective solutions for consolidating complex logic designs. The A42MX24 variant specifically offers a balance between gate count and pin availability for mid-range embedded applications.

Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the discontinued status of the MX family. Designers should evaluate newer Microchip PolarFire or Igloo2 FPGA families for modern alternatives, noting significant architectural differences and potential PCB redesign requirements.
