A3P400-1FG484

Field Programmable Gate Array Overview

The A3P400-1FG484 is a ProASIC3 Flash Field Programmable Gate Array manufactured by Microsemi. It features 400,000 system gates and 9,216 VersaTiles within a 484-pin Fine Pitch Ball Grid Array (FG484) package. The device operates at a maximum clock frequency of 350 MHz and supports an industrial temperature range from -40°C to +100°C. Key specifications include up to 54 kbits of embedded True Dual-Port SRAM, 1 kbit of nonvolatile FlashROM, and six Clock Conditioning Circuits with one integrated PLL. It utilizes a 130-nm flash-based CMOS process.

Field Programmable Gate Array Feature Summary

• Nonvolatile flash technology enables instant-on operation without external boot PROMs and immunity to firm errors caused by high-energy neutrons.
• Integrated security mechanisms including FlashLock and on-chip AES decryption protect intellectual property and configuration data against unauthorized access.
• Advanced I/O structure supports mixed-voltage operation across multiple banks and includes registers for Double-Data-Rate applications.

Field Programmable Gate Array Applications

• Avionics systems requiring radiation tolerance and secure configuration
• Networking and communications equipment utilizing high-speed DDR I/O standards
• Industrial control systems needing instant-on capabilities and low power consumption

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade indicated by the suffix '1', which denotes performance faster than the standard grade. Confirm that the FG484 package dimensions and pinout match the target PCB footprint. Ensure the industrial temperature rating aligns with environmental requirements. Check for RoHS compliance status associated with the 'G' packaging suffix if applicable to the specific order code variant.

Field Programmable Gate Array Selection Notes

Select this device for designs requiring high logic density with nonvolatile storage and strong security features. Consider the available 54 kbits of SRAM for buffering or state machine implementation. Evaluate the I/O bank configurations to ensure compatibility with required voltage standards. Verify that the 350 MHz performance meets timing constraints for the intended application logic.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 Flash family, representing third-generation flash FPGA technology from Microsemi. It bridges the gap between ASIC costs and FPGA flexibility, offering reprogrammability with the security and instant-on benefits of flash memory. The family supports optional ARM Cortex-M1 soft processors in higher-density variants.

Field Programmable Gate Array Replacement Considerations

The M1A3P400 series offers similar logic resources but integrates an ARM Cortex-M1 processor. For pure logic replacement, other ProASIC3 devices like the A3P600 provide higher density but may require pinout adaptation. Review the ProASIC3E datasheet for next-generation alternatives with enhanced features.
