A42MX16-TQ176A

Overview

The A42MX16-TQ176A is a Field Programmable Gate Array (FPGA) from the Microsemi MX family, designed as a high-capacity single-chip ASIC alternative. It provides approximately 24,000 system gates and 295 Configurable Logic Blocks (CLBs). The device supports mixed-voltage operation with supply ranges of 3V to 3.6V and 4.5V to 5.5V. It features up to 140 user-programmable I/O pins in a 176-LQFP package. Key performance metrics include a maximum clock frequency of 48.24 MHz and a CLB delay of 3.72 ns. It includes up to 2.5 kbits of configurable dual-port SRAM and operates within a temperature range of -40°C to 125°C.

Feature Summary

• Supports mixed-voltage operation for core and I/Os, compatible with PCI-compliant interfaces.
• Provides deterministic, user-controllable timing with up to 100% resource utilization and pin locking capabilities.
• Integrates configurable dual-port SRAM for fast access and FIFO applications.

Applications

• High-speed controllers and address decoding logic
• Peripheral bus interface implementations
• DSP and co-processor functions

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm package type and speed grade. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Check for any Product Change Notifications regarding packaging or manufacturing origin updates.

Selection Notes

Select this component when a cost-effective FPGA solution replacing multiple PALs, CPLDs, or FPGAs is required. Ensure the design fits within the 24,000 gate capacity and utilizes the available 140 I/Os. Verify that the 176-pin package dimensions meet the PCB layout constraints.

Part Context

This part belongs to the 40MX and 42MX FPGA families, which are positioned as high-performance, low-power alternatives to complex programmable logic devices. The MX series is known for consolidating logic functions into a single chip, reducing board space and development cycles compared to discrete logic solutions.

Replacement Considerations

Compatible variants within the same family include A42MX16-2TQG176 and A42MX16-TQG176A. These parts share similar gate counts and I/O configurations but may differ in speed grades or specific package tolerances. Consult the manufacturer's cross-reference guide for exact functional equivalence.
