A1240A-TQG176C

Field Programmable Gate Array Overview

The A1240A-TQG176C is a Field Programmable Gate Array (FPGA) from the Microsemi ACT 2 family, utilizing antifuse technology. It features 1232 Configurable Logic Blocks (CLBs) and an equivalent capacity of 8000 gates. The device operates at a maximum clock frequency of 75 MHz with a typical CLB combinatorial delay of 4.3 ns. It supports a supply voltage range of 4.5 V to 5.5 V, rated at 5 V nominal. The component is housed in a 176-pin Thin Quad Flat Package (TQFP) with a grid array terminal configuration.

Field Programmable Gate Array Feature Summary

• ACT 2 antifuse architecture providing non-volatile configuration without SRAM overhead
• High-density logic integration replacing up to 200 TTL packages
• Integrated design library containing over 500 macro functions for rapid development

Field Programmable Gate Array Applications

• Military and aerospace systems requiring high-reliability programmable logic
• Industrial control applications needing robust signal processing
• Communication infrastructure equipment demanding stable gate arrays

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'TQG176C' against official Microsemi documentation to confirm package type and temperature grade. Confirm current lifecycle status as ACT 2 devices may be End-of-Life or Life-Buy candidates. Ensure compatibility with existing PCB footprints for 176-pin TQFP assemblies before procurement.

Field Programmable Gate Array Selection Notes

Select this model when antifuse reliability is preferred over volatile SRAM FPGAs. Compare against the A1240A-VQ176B if a ceramic CPGA package is required instead of plastic TQFP. Consider the A1240XL series if higher performance speeds exceeding 75 MHz are necessary for the application.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT 2 FPGA family, known for its radiation tolerance and security due to antifuse technology. The A1240A variant represents a mid-range density option within this series, balancing logic capacity with power consumption for specialized embedded applications.
