A3P400-2FG484

Field Programmable Gate Array Overview

The A3P400-2FG484 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 with a 1.0 mm pitch. The device operates at a maximum frequency of 350 MHz and supports up to 194 user I/Os across four banks. It includes 54 kbits of embedded SRAM and 1 kbit of nonvolatile FlashROM. The -2 speed grade indicates performance 25% faster than the standard grade, while the 'I' suffix denotes an industrial temperature range of -40°C to +100°C.

Field Programmable Gate Array Feature Summary

• Nonvolatile flash-based architecture providing instant-on capability without external boot PROMs.
• Integrated security features including FlashLock and AES decryption for IP protection.
• Flexible clock conditioning circuits with one integrated PLL for precise phase shifting and jitter reduction.
• Support for mixed-voltage I/O standards including LVDS and DDR capabilities.

Field Programmable Gate Array Applications

• Secure remote field updates over public networks
• Avionics and computing systems requiring low power consumption
• Networking and communications equipment
• Consumer electronics needing instant-on functionality

Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffixes against the manufacturer's official datasheet to confirm package type, speed grade, and temperature range. Ensure compatibility with existing board layouts as FG256 and FG484 packages are footprint-compatible. Confirm RoHS compliance status if required for your manufacturing process.

Field Programmable Gate Array Selection Notes

Select this device when high-density logic is needed with nonvolatile configuration storage. Consider the -2 speed grade for applications requiring higher clock frequencies than the standard grade provides. Verify that the 194 available I/Os meet interface requirements and check if the embedded memory sizes are sufficient for your design needs.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 Flash family, which bridges the gap between ASICs and SRAM-based FPGAs. It offers reprogrammability with the security and instant-on benefits of flash technology. The A3P400 represents a mid-range density option within the family, suitable for complex logic designs without the cost of higher-density parts.

Field Programmable Gate Array Replacement Considerations

Check for pin-compatible alternatives within the same package size. Higher density devices like the A3P600 or A3P1000 may be compatible if resources allow. Lower density options like the A3P250 might fit if logic requirements are reduced. Always verify electrical characteristics and timing constraints before substitution.

Field Programmable Gate Array FAQ

Does the A3P400 support ARM Cortex-M1 processors?

No, the standard A3P400 does not support ARM Cortex-M1. Devices with ARM support have part numbers starting with M1A3P.

What is the difference between the -1 and -2 speed grades?

The -2 speed grade offers performance that is 25% faster than the standard (-1) grade, allowing for higher maximum operating frequencies.

Can the FlashROM be programmed from the internal logic array?

No, the FlashROM can only be programmed via the JTAG programming interface and cannot be accessed or written by the internal FPGA logic.
