AX250-2FGG256

The AX250-2FGG256 is an Axcelerator family antifuse FPGA implementing Microchip’s AX architecture as a single-chip, nonvolatile solution. It delivers 250,000 equivalent system gates with 4,224 logic elements, 138 user I/Os and approximately 55,296 bits of on-chip RAM (55,296 total RAM bits reported in the family profile; this device lists 55,296/55,296 as total RAM bits in the family table).

Designed for applications that demand deterministic timing, embedded FIFO capability and multi-standard I/O flexibility, the device combines on-chip SRAM/FIFO control, segmentable clocks and integrated PLLs to support high-performance data-path and control logic in a surface-mount 256-LBGA package.

Key Features

• Core & Architecture AX architecture based on antifuse technology providing a single-chip, nonvolatile FPGA implementation and deterministic, user-controllable timing.
• Logic Capacity 250,000 equivalent system gates and 4,224 logic elements (cells) for medium-density logic integration.
• Embedded Memory Total on-chip RAM bits reported as 55,296 in the Axcelerator family profile; memory blocks include variable-aspect 4,608-bit RAM blocks with embedded FIFO control logic.
• I/O Flexibility 138 user I/Os with support for mixed voltage operation (1.5V, 1.8V, 2.5V, 3.3V) and differential standards including LVDS; I/Os are bank-selectable and support programmable slew and drive strength.
• High-Speed Performance Family-level performance figures include 350+ MHz system performance and 500+ MHz internal performance; I/Os capable of 700 Mb/s LVDS signaling.
• Clocking & PLL Segmentable clock resources and embedded PLLs with frequency synthesis capabilities to support a wide range of system clocking needs.
• Security & Programming FuseLock™ programming technology for design protection, plus boundary-scan (JTAG) support for testing and in-system diagnostics.
• Package & Mounting Surface-mount 256-LBGA (supplier package: 256-FPBGA, 17×17) for compact board-level integration.
• Power & Operating Range Core supply range 1.425 V to 1.575 V (nominal 1.5 V) and commercial operating temperature 0 °C to 70 °C.
• Compliance RoHS-compliant.

Typical Applications

• High-speed data buffering and interface bridging — Embedded SRAM and FIFO control logic with LVDS-capable I/Os enable on-chip buffering and protocol bridging for high-bandwidth links.
• Deterministic control and timing — Segmentable clocks and user-controllable timing make the device suitable for systems that require predictable, repeatable timing.
• Protocol conversion and glue logic — Mixed-voltage, bank-selectable I/Os and programmable drive/slew settings simplify interfacing between different I/O standards on a single board.
• Compact system integration — The 256-LBGA surface-mount package allows medium-density logic and memory to be integrated into space-constrained designs.

Unique Advantages

• Single-chip nonvolatile solution: Eliminates the need for external configuration memory and simplifies power-up behavior for production systems.
• Embedded FIFO and SRAM control: Reduces BOM by providing configurable on-chip buffering and memory management for streaming or packetized data.
• Flexible, multi-standard I/Os: Bank-selectable I/Os and support for single-ended and differential standards enable easy interfacing to legacy and modern peripherals.
• Deterministic performance: User-controllable timing and segmentable clock resources provide predictable timing behavior for real-time and synchronous systems.
• Compact package with surface-mount mounting: 256-LBGA (256-FPBGA, 17×17) offers a balance of pin count and board area for medium-density FPGA integration.

Why Choose AX250-2FGG256?

The AX250-2FGG256 positions itself as a medium-density Axcelerator FPGA that combines nonvolatile antifuse programming, substantial logic capacity and embedded memory/FIFO control in a compact 256-LBGA package.
