A3P400-FG484I

Field Programmable Gate Array Overview

The A3P400-FG484I is a ProASIC3 Flash Field Programmable Gate Array manufactured by Microsemi. It features 400,000 system gates and 9,216 configurable logic blocks (VersaTiles). The device operates within an industrial temperature range of -40°C to +100°C junction temperature. It utilizes a Fine Pitch Ball Grid Array package with 484 pins and supports up to 194 user I/Os. Key specifications include a maximum system performance frequency of 350 MHz, 54 kbits of embedded true dual-port SRAM, and 1 kbit of nonvolatile FlashROM.

Field Programmable Gate Array Feature Summary

• Nonvolatile flash-based architecture providing instant-on capability without external boot PROMs.
• Integrated security mechanisms including AES-128 decryption and FlashLock for intellectual property protection.
• Flexible clock conditioning circuits with six CCC blocks and one integrated PLL.
• Support for mixed-voltage I/O standards ranging from 1.5 V to 3.3 V.

Field Programmable Gate Array Applications

• Secure remote in-system programming for field upgrades
• Low-power single-chip solutions replacing ASICs
• Systems requiring instant-on initialization before processor wake-up

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'FG' corresponds to the Fine Pitch Ball Grid Array package with 484 pins. Confirm that the 'I' suffix indicates the industrial temperature grade (-40°C to +100°C) as defined in the ordering information. Ensure compatibility with the 130-nm flash process requirements during integration.

Field Programmable Gate Array Selection Notes

Select this device for designs requiring 400,000 system gates with nonvolatile configuration storage. Consider the FG484 package if high pin count and fine pitch are necessary. Verify that the 194 available user I/Os meet interface requirements and that the 54 kbits of SRAM suffices for data buffering needs.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 Flash family, which offers reprogrammable flash technology. It sits between the A3P250 and A3P600 devices in terms of logic density. The family is characterized by its ability to retain programmed designs when powered off and support ARM Cortex-M1 soft processors in specific variants.
