A3P125-1FG144I

Field Programmable Gate Array Overview

The A3P125-1FG144I 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 includes 36,864 bits of embedded True Dual-Port SRAM and supports up to 97 user I/Os. It operates within a supply voltage range of 1.425V to 1.575V and functions at temperatures from -40°C to +100°C TJ. Packaged in a 144-LBGA (13x13 mm) with 1mm pitch, it utilizes non-volatile flash technology for immediate operation upon power-up.

Field Programmable Gate Array Feature Summary

• Non-volatile flash-based architecture enables Live at Power-Up (LAPU) functionality without external configuration memory.
• Supports In-System Programming (ISP) via JTAG using IEEE 1532-compliant protocols.
• Integrated security features include on-chip 128-bit Advanced Encryption Standard (AES) decryption for secure ISP.

Field Programmable Gate Array Applications

• Secure industrial control systems requiring immediate boot capability
• Military and aerospace avionics applications demanding radiation tolerance and reliability
• Embedded logic replacement in communication infrastructure equipment

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +100°C TJ) against the official datasheet. Confirm the package designation matches the 144-LBGA form factor. Check for current Product Change Notifications (PCNs) regarding assembly sites or material composition updates before finalizing procurement orders.

Field Programmable Gate Array Selection Notes

Select this component when non-volatile configuration and instant-on operation are required, eliminating the need for external PROMs. Ensure the design fits within the 36,864-bit SRAM limit and 97 I/O constraints. Verify that the 1.5V core voltage and mixed-voltage I/O capabilities align with the target system's power rails and signal levels.

Field Programmable Gate Array Part Context

This part belongs to the Microchip ProASIC3 Flash FPGA family, which bridges the gap between ASICs and standard FPGAs by offering reprogrammability with flash persistence. It serves as a drop-in replacement for complex discrete logic or mask-programmed gate arrays in high-reliability environments where data retention during power loss is critical.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible alternatives within the same package include other speed grades of the A3P125 series, such as the A3P125-FG144II, provided the timing requirements are met. Cross-family migration to IGLOO or PolarFire may require schematic and layout redesign due to architectural differences.
