Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'TQG176I' against official Microsemi documentation to confirm the package type, speed grade, and industrial temperature rating. Ensure that design files are compatible with the ACT 3 family toolchain. Check for current availability status as older generation FPGAs may have limited stock or end-of-life implications.

Field Programmable Gate Array Selection Notes

Select this model when a high pin count and substantial logic density are required within a TQFP form factor. Compare against the A1460B variant if higher performance speeds are needed, or consider the A1240A for military-grade temperature ranges. Evaluate the total I/O requirements against the maximum 228 pins to ensure adequate connectivity for the target application interface.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT 3 family of Flash-based FPGAs, designed to replace complex discrete logic. The ACT 3 series bridges the gap between standard PLDs and larger ASICs, offering reprogrammability with non-volatile configuration. It is part of the broader Microsemi portfolio acquired from Adaptec, focusing on cost-effective, high-performance programmable solutions.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package may include other ACT 3 devices such as the A1240A or A1440A, subject to logic resource sufficiency. Verify electrical compatibility and timing constraints before substituting. Consult Microsemi cross-reference guides for validated alternatives.
