A3P125-TQG144I

Field Programmable Gate Array Overview

The A3P125-TQG144I is a ProASIC3 Flash Field-Programmable Gate Array manufactured by Microchip Technology. It features 125,000 system gates and 3,072 Configurable Logic Blocks (CLBs). The device operates with a supply voltage range of 1.425V to 1.575V and supports up to 100 user I/Os. It utilizes a 144-pin Thin Quad Flat Package (TQFP) with dimensions of 20x20 mm. The industrial temperature grade variant supports operation from -40°C to +85°C. Key specifications include a maximum operating frequency of 231 MHz and 36,864 bits of embedded SRAM.

Field Programmable Gate Array Feature Summary

• Non-volatile flash-based architecture enabling live-at-power-up functionality without external configuration memory.
• Supports in-system programming via JTAG for design updates and security management.
• Integrated true dual-port SRAM blocks for high-speed data buffering and processing.

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic logic execution.
• Automotive electronics interfaces and sensor signal conditioning.
• Communication protocol conversion and interface bridging.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C) against the commercial grade variant. Confirm package integrity as the TQFP form factor requires careful handling during surface-mount assembly. Check current availability status as legacy FPGA families may have limited stock or end-of-life notifications.

Field Programmable Gate Array Selection Notes

Select this component when non-volatile configuration and low standby power are required compared to SRAM-based FPGAs. Ensure the 144-pin TQFP footprint fits the PCB layout constraints. Verify that the 231 MHz performance meets the timing requirements of the target application logic.

Field Programmable Gate Array Part Context

This part belongs to the Microchip ProASIC3 family, which bridges the gap between ASICs and standard FPGAs. It offers the flexibility of programmable logic with the persistence of flash technology. The A3P125 model represents the mid-range capacity within this series, suitable for moderate complexity designs.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements within the same package are limited due to specific speed grades. Consider the A3P125-FGG144I for BGA packaging upgrades if board space allows. Verify functional compatibility with newer Microchip PolarFire or IGLOO2 families for long-term supply assurance.
