A3P250-2FGG256

Field Programmable Gate Array Overview

The A3P250-2FGG256 is a Field Programmable Gate Array belonging to the ProASIC3 Flash family, manufactured by Microchip Technology. It features 3000 Logic Elements and 250,000 system gates within a 256-pin FineLine BGA package measuring 17 x 17 mm with a 1.0 mm pitch. The device operates on a core voltage range of 1.425 V to 1.575 V and supports up to 157 user I/Os. It includes 36 kbit of embedded memory and achieves a maximum operating frequency of 350 MHz across an industrial temperature range of -40°C to +85°C.

Field Programmable Gate Array Feature Summary

• Non-volatile flash-based architecture enabling live at power-up operation without external configuration memory
• Support for mixed-voltage I/O standards including LVCMOS, LVTTL, LVDS, and LVPECL across selectable banks
• Integrated Clock Conditioning Circuits (CCC) with Phase-Locked Loops for advanced clock management

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic boot times
• Telecommunications infrastructure utilizing high-speed differential signaling
• Military and aerospace avionics demanding radiation-tolerant programmable logic

Field Programmable Gate Array Procurement Notes

Verify the specific suffix '2' indicates the industrial temperature grade (-40°C to +85°C) rather than commercial variants. Confirm the FBGA-256 package dimensions match the target PCB footprint. Ensure design tools support the legacy Actel/Microchip ProASIC3 flow for bitstream generation.

Field Programmable Gate Array Selection Notes

Select this model when non-volatile configuration and low standby power are critical compared to SRAM-based FPGAs. Compare against the A3P030 or A3P1000 if gate counts differ from the required 3000 LEs. Verify that the 157 available I/O pins satisfy the interface requirements for the specific application.

Field Programmable Gate Array Part Context

This component is part of the ProASIC3 Flash family, which bridges the gap between ASICs and standard SRAM FPGAs. Originally developed by Actel before its acquisition by Microchip Technology, the series is characterized by its instant-on capability and resistance to single-event upsets, making it suitable for secure and reliable embedded applications.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible alternatives within the same family include the A3P250-VQG100I in a QFP package or other A3P250 variants with different speed grades. Cross-family migration to Microchip PolarFire or IGLOO2 requires schematic and firmware redesign due to architectural differences.
