A3P400-1FGG484

Field Programmable Gate Array Overview

The A3P400-1FGG484 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 (FBGA) package with a 1.0 mm pitch. The device supports a maximum operating frequency of 272 MHz and operates on a 1.5 V core voltage. It includes up to 54 kbits of embedded SRAM and 1 kbit of nonvolatile FlashROM. The industrial temperature grade (-I suffix) ensures operation between -40°C and +100°C.

Field Programmable Gate Array Feature Summary

• Nonvolatile flash-based architecture providing instant-on capability without external boot PROMs.
• Integrated security mechanisms including AES decryption and FlashLock for intellectual property protection.
• Flexible I/O structure supporting mixed-voltage standards from 1.5 V to 3.3 V.
• Embedded clock conditioning circuits with phase-locked loop capabilities.

Field Programmable Gate Array Applications

• Secure remote in-system programming for field upgrades
• Low-power single-chip solutions replacing ASICs
• Systems requiring immediate power-up execution

Field Programmable Gate Array Procurement Notes

Verify the specific speed grade '1' and industrial temperature range '-I' against project requirements. Confirm that the FBGA-484 footprint matches the PCB layout. Ensure design tools support the ProASIC3 family for configuration and programming.

Field Programmable Gate Array Selection Notes

Select this model for designs requiring 400k gates with industrial temperature tolerance. Compare gate density and I/O counts against A3P250 or A3P600 if resource constraints exist. Verify compatibility with existing JTAG programming infrastructure.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 Flash Family, which bridges the gap between standard FPGAs and ASICs. It offers reprogrammability with nonvolatile storage, distinguishing it from SRAM-based counterparts like the PolarFire series.
