A1460A-1TQG176I

Field Programmable Gate Array Overview

The A1460A-1TQG176I is a Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 848 logic cells and operates at a maximum clock frequency of 116.8 MHz. The device utilizes CMOS technology and is supplied in a 176-pin Thin Quad Flatpack (TQFP) package, specifically designated as TQG176. It supports 168 input/output terminals and functions within an industrial temperature range of -40 °C to 85 °C. The nominal supply voltage is 5 V. This component is classified as a programmable logic device suitable for embedded applications requiring moderate logic density.

Field Programmable Gate Array Feature Summary

• Configurable logic architecture with 848 cells for custom digital circuit implementation
• Industrial-grade thermal stability supporting operation from -40 °C to 85 °C
• High-density I/O configuration with 168 accessible terminals in a compact 176-pin package

Field Programmable Gate Array Applications

• Embedded control systems in industrial automation equipment
• Signal processing interfaces for communication infrastructure
• Prototyping and development of custom digital logic circuits

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix '1' corresponds to the required 116.8 MHz performance limit for your design timing constraints. Confirm that the 5 V supply voltage aligns with your system power rails, as this device does not support lower voltage levels natively. Ensure the TQFP176 footprint matches your PCB layout specifications before ordering.

Field Programmable Gate Array Selection Notes

Select this model when 848 logic cells are sufficient for the target application, balancing cost against higher-capacity FPGAs. Consider the 5 V operating voltage requirement compared to modern low-voltage alternatives. The 176-pin TQFP package offers a surface-mount solution suitable for standard assembly processes, provided the pin count meets the interface requirements of the host system.

Field Programmable Gate Array Part Context

This part belongs to the A1460B/A1460A series of Flash-based FPGAs from Microsemi. These devices are designed for applications requiring non-volatile configuration and high reliability. The A1460A variant typically represents a specific speed or feature subset within the broader family, sharing architectural similarities with the A1460B but potentially differing in timing characteristics or available resources.

Field Programmable Gate Array Replacement Considerations

Direct replacements may include other parts within the Microsemi A1460 family, such as the A1460B series, if speed grades are compatible. Cross-vendor equivalents require careful evaluation of logic cell counts, I/O compatibility, and voltage levels. Verify that any substitute maintains the same package outline dimensions for mechanical fit.
