A3P400-FG256I

Field Programmable Gate Array Overview

The A3P400-FG256I is a ProASIC3 Flash Field-Programmable Gate Array manufactured by Microchip Technology. It features 400,000 system gates and 178 I/Os within a 256-pin FBGA package. The device operates on a 1.5 V core voltage with a range of 1.425 V to 1.575 V. It supports a maximum operating frequency of 310 MHz and functions between -40°C and +85°C.

Field Programmable Gate Array Feature Summary

• Non-volatile flash-based architecture providing instant-on capability without external configuration memory.
• Supports mixed-voltage I/O standards including LVTTL, LVCMOS, and PCI/PCI-X compatibility.
• Includes six Clock Control Blocks (CCBs) with integrated Phase-Locked Loops for flexible clock management.

Field Programmable Gate Array Applications

• Industrial control systems requiring non-volatile logic and instant power-up readiness.
• Telecommunications infrastructure utilizing high-speed serial interfaces and LVDS signaling.
• Automotive electronics applications demanding robust operation across extended temperature ranges.

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade suffix in the part number against official datasheets, as variants like A3P400-1 or A3P400-2 indicate different performance characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering to ensure assembly process compatibility.

Field Programmable Gate Array Selection Notes

Select this component when a mid-range gate count FPGA with non-volatile storage is required. Ensure the design fits within the 400K gate limit and utilizes the available 178 I/Os. Verify that the 1.5V core voltage aligns with the system power budget and that the FBGA-256 footprint matches the PCB layout constraints.

Field Programmable Gate Array Part Context

This device belongs to the ProASIC3 family, which bridges the gap between ASICs and SRAM-based FPGAs. It offers lower power consumption than SRAM counterparts while maintaining reprogrammability. The family is designed for cost-sensitive applications needing high reliability and security through its flash technology.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements exist within the same ProASIC3 family, such as the A3P060 or A3P250, though logic capacity differs. For higher performance, consider the A3PE series. Verify that any substitute maintains the required 256-pin FBGA package and voltage specifications.
