A42MX16-TQG176

Overview

The A42MX16-TQG176 is a Field Programmable Gate Array (FPGA) from the Microchip MX series, manufactured by Microchip Technology. It features 24,000 system gates and 608 Logic Elements (LEs). The device provides 140 user-programmable I/O pins and is housed in a 176-LQFP surface-mount package. It operates within a supply voltage range of 3V to 3.6V or 4.5V to 5.5V. The component supports an extended industrial operating temperature range from -40°C to +125°C.

Feature Summary

• Single-chip ASIC alternative capable of consolidating logic previously implemented in multiple PALs, CPLDs, and FPGAs.
• Supports mixed-voltage operation with PCI-compliant I/Os for flexible integration.
• Includes up to 2.5 kbits of configurable dual-port SRAM for high-performance data handling.

Applications

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

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm exact package dimensions and thermal characteristics. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the ordering part number matches the required temperature grade and pin count specifications for your design.

Selection Notes

Select this model when a dense FPGA solution with 140 I/Os is required in a TQFP form factor. Compare against other MX series variants if different I/O counts or package sizes are needed. Verify that the 24,000 gate capacity meets the logic density requirements of the target application before finalizing the component choice.

Part Context

This component belongs to the Microchip A42MX16 family, which offers high performance at 5V. The MX devices are designed to shorten system design cycles by replacing multiple discrete logic components. This specific part represents a mid-range density option within the broader Actel/Microchip FPGA portfolio.

Replacement Considerations

Check for direct substitutes within the same MX family, such as the A42MX16-TQG176A, ensuring pin compatibility and electrical parameter alignment. Verify any package changes or suffix modifications with the manufacturer to guarantee functional equivalence.
