A3P400-1FG144I

Field Programmable Gate Array Overview

The A3P400-1FG144I is a ProASIC3 FPGA from Microchip Technology, featuring 400,000 system gates and 97 I/Os. It operates on a 1.5 V supply voltage (range 1.425 V to 1.575 V) within an industrial temperature range of -40°C to +85°C. The device utilizes an FBGA-144 package for surface mount installation. It supports maximum operating frequencies up to 272 MHz and includes humidity sensitivity classification. This non-RoHS compliant component is designed for programmable logic applications requiring reliable flash-based configuration.

Field Programmable Gate Array Feature Summary

• Flash-based non-volatile architecture enabling instant-on functionality without external configuration memory.
• Integrated ARM Cortex-M1 processor core for embedded control tasks alongside programmable logic.
• Supports multiple voltage domains including 1.5 V core and 3.3 V I/O interfaces.

Field Programmable Gate Array Applications

• Industrial automation control systems
• Telecommunications interface modules
• Automotive electronics subsystems

Field Programmable Gate Array Procurement Notes

Verify RoHS compliance status as the component is listed as non-compliant in available documentation. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprint designs for the FBGA-144 package. Check for any export control restrictions or specific ordering suffixes that may affect availability.

Field Programmable Gate Array Selection Notes

Select this model when a balance of moderate logic density and embedded processing is required. Compare against the A3P400-2 variant if higher speed grades are necessary. Consider the M1A3P400 series if enhanced low-power features are prioritized over raw performance. Verify thermal management needs for the FBGA-144 package in enclosed environments.

Field Programmable Gate Array Part Context

This part belongs to the Microchip ProASIC3 family, which bridges the gap between ASICs and standard FPGAs. The family offers radiation tolerance options and high reliability for aerospace and defense markets. The A3P400 specifically targets mid-range complexity designs requiring deterministic timing and low power consumption.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible alternatives within the same package include the A3P400-2FG144I for higher speed grades. The M1A3P400-FG144I offers similar I/O counts but with different power characteristics. Cross-family migration to Actel or SmartFusion devices requires schematic and layout redesign.
