A3P125-2FG144I

Field Programmable Gate Array Overview

The A3P125-2FG144I is a ProASIC3 flash-based Field Programmable Gate Array manufactured by Microchip Technology. It features 125,000 system gates and 36,864 bits of embedded SRAM within a 144-pin FineLine BGA package. The device operates with a core voltage range of 1.425V to 1.575V and supports an industrial temperature range from -40°C to +100°C junction temperature. It provides 97 user I/Os and utilizes non-volatile flash technology for immediate configuration at power-up.

Field Programmable Gate Array Feature Summary

• Flash-based architecture enables live-at-power-up operation without external configuration memory
• Supports mixed-voltage I/O standards including LVCMOS and LVTTL across multiple banks
• Integrates true dual-port SRAM for high-speed data buffering and processing

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic boot times
• Automotive electronics operating in harsh thermal environments
• Telecommunications infrastructure interface logic

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix '2' against the official datasheet to confirm timing characteristics. Confirm the 'I' suffix indicates the industrial temperature rating. Ensure the 144-FPBGA package dimensions match the target PCB footprint requirements before ordering.

Field Programmable Gate Array Selection Notes

Select this component when non-volatile configuration and low standby power are required. Compare gate density and I/O count against the AGL series for lower power needs or the A3PE series for higher performance. Verify that the 1.5V core voltage aligns with the system power design constraints.

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 reprogrammability of an FPGA with the instant-on capability and lower cost of an ASIC. The 125K gate count places it in the mid-range capacity segment of the portfolio.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements within the same package may include other speed grades of the A3P125 series, such as the A3P125-1FG144I or A3P125-3FG144I, provided timing requirements are met. Cross-family migration to IGLOO devices requires schematic and layout redesign.
