A3P400-FG144I

Field Programmable Gate Array Overview

The A3P400-FG144I is a ProASIC3 field-programmable gate array manufactured by Microchip Technology. It features 5,000 logic elements and supports up to 97 I/Os within a 144-pin FBGA package. The device operates at a maximum frequency of 310 MHz with a supply voltage range of 1.425 V to 1.575 V. It functions within an industrial temperature range of 0°C to +70°C. This non-volatile FPGA utilizes flash-based technology for instant-on capability.

Field Programmable Gate Array Feature Summary

• Supports multiple low-power modes to optimize energy consumption
• Includes built-in debug capabilities via the ICE-100 interface

Field Programmable Gate Array Applications

• Industrial automation control systems
• Consumer electronics hardware interfaces
• Automotive body control modules
• Telecommunications signal processing

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (0°C to +70°C) against the official datasheet. Confirm RoHS compliance status as some variants may differ. Check for export control classifications such as ECCN 3A991D. Ensure the 144-pin FBGA footprint matches the target PCB design constraints.

Field Programmable Gate Array Selection Notes

Select this component when instant-on functionality is required without external boot memory. Compare logic density against the A3P125 or A3P250 if resource usage is lower. Verify that the 310 MHz speed grade meets timing requirements. Consider the M1A3P400 variant if an integrated ARM Cortex-M1 core is necessary for complex control logic.

Field Programmable Gate Array Part Context

This part belongs to the Microchip ProASIC3 family, which bridges the gap between discrete logic and complex FPGAs. The series is characterized by its flash-based non-volatility and low power consumption. It serves as a drop-in replacement for complex PALs and GALs in legacy designs requiring higher integration.

Field Programmable Gate Array Replacement Considerations

The M1A3P400-FG144 offers similar logic density but includes an integrated ARM Cortex-M1 processor. The A3P400-2FG144 provides a higher speed grade of 310 MHz but lacks the industrial temperature rating. Verify pin compatibility before substituting.
