A3P1000-FG256T

Field Programmable Gate Array Overview

The A3P1000-FG256T is a Flash-based Field Programmable Gate Array from the Microchip ProASIC3 family. It features 1,000,000 system gates and 24,576 Configurable Logic Blocks (CLBs). The device supports up to 300 user I/Os and includes up to 144 Kbits of True Dual-Port SRAM. It operates with a core voltage range of 1.425 V to 1.575 V and supports mixed-voltage I/O standards including 1.5 V, 1.8 V, 2.5 V, and 3.3 V. The component is housed in a 256-pin FineLine BGA package.

Field Programmable Gate Array Feature Summary

• Non-volatile Flash technology enabling instant-on functionality without external configuration memory.
• Support for high-speed DDR interfaces and LVDS-capable I/Os for advanced signal integrity.
• Integrated Triple Core Controller (CCC) blocks with phase-locked loops for clock management.
• Mixed-voltage I/O bank selection allowing operation across multiple voltage domains.

Field Programmable Gate Array Applications

• High-density digital logic prototyping and emulation.
• Industrial control systems requiring non-volatile configuration.
• Telecommunications infrastructure utilizing LVDS signaling.
• Test and measurement equipment needing rapid reconfiguration.

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'T' against official Microchip documentation to confirm tape-and-reel packaging status, as standard listings may indicate tray packaging. Ensure the operating temperature grade matches the design requirements, as industrial variants typically extend to -40°C. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical production runs may vary in environmental certification.

Field Programmable Gate Array Selection Notes

Select this model when a high gate count FPGA with embedded Flash configuration is required. Compare against the M1A3P1000 variant if an integrated ARM Cortex-M1 processor is needed for hybrid applications. Evaluate the A3P1000L series if lower power consumption is critical, noting differences in supply voltage ranges. Ensure the 256-pin FBGA footprint fits the target PCB layout constraints.

Field Programmable Gate Array Part Context

This component belongs to the ProASIC3 Flash FPGA family, which bridges the gap between ASICs and traditional SRAM-based FPGAs. It offers the density of larger FPGAs with the simplicity of Flash-based programming. The A3P1000 represents the high-end capacity within the standard ProASIC3 lineup, providing extensive I/O options and significant on-chip memory resources for complex designs.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the A3P1000 series such as A3P1000-1FGG256 or A3P1000-2FGG256M, depending on speed grade requirements. For upgraded performance with similar form factors, consider the ProASIC3L family, though voltage specifications differ.
