A3P125-TQ144I

Field Programmable Gate Array Overview

The A3P125-TQ144I is a ProASIC3 Flash Field-Programmable Gate Array manufactured by Microchip Technology. It features 125,000 system gates and 36,864 bits of embedded RAM within a 144-pin Thin Quad Flat Package (TQFP). The device operates on a core supply voltage ranging from 1.425 V to 1.575 V and supports an industrial temperature range of -40°C to +85°C. It provides 97 user I/Os and achieves a maximum operating frequency of 231 MHz. The component utilizes non-volatile flash technology for instant power-up functionality.

Field Programmable Gate Array Feature Summary

• Instant-on capability via non-volatile flash memory architecture
• Support for mixed-voltage I/O standards including LVCMOS and LVTTL
• Industrial-grade thermal performance for extended temperature operation

Field Programmable Gate Array Applications

• Industrial control systems requiring reliable logic processing
• Automotive electronics operating in harsh thermal environments
• Communication interface adapters and protocol converters

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C) against the official datasheet. Confirm package integrity upon receipt as moisture sensitivity level 3 requires proper handling. Check for recent Product Change Notifications regarding assembly sites or software tool updates before finalizing procurement orders.

Field Programmable Gate Array Selection Notes

Select this model when non-volatile storage and instant power-up are required without external configuration memory. Ensure the design fits within the 125,000 gate limit and 36,864-bit RAM capacity. Verify that the TQFP package dimensions align with the PCB footprint constraints compared to BGA alternatives in the same family.

Field Programmable Gate Array Part Context

This part belongs to the ProASIC3 Flash family, which bridges the gap between ASICs and SRAM-based FPGAs. Unlike volatile counterparts, it retains configuration data without power. The TQ144 variant offers a leaded package option suitable for applications where board space allows for larger footprints but requires robust mechanical mounting.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the ProASIC3 family include A3P125-FG144I and A3P125-VQG100IY, subject to package and I/O count verification. Cross-family migration to PolarFire or IGLOO series requires schematic redesign due to architectural differences.
