AX250-1FG256

The AX250-1FG256 is a Microchip Technology Axcelerator antifuse FPGA based on the AX architecture, delivering a single-chip, nonvolatile solution for high-performance embedded logic. It combines deterministic timing, segmentable clocks, PLL-based clock synthesis and embedded SRAM/FIFO control to address designs requiring secure, ASIC-like performance and on-chip memory integration.

With 250,000 equivalent system gates, 4,224 logic elements and approximately 55 kbits of embedded RAM, this device targets applications that need high internal throughput, flexible I/O standards and a compact 256-LBGA package for surface-mount system integration.

Key Features

• Core Capacity — 250,000 equivalent system gates and 4,224 logic elements provide significant on-chip logic density for complex custom functions.
• Embedded Memory & FIFOs — Approximately 55 kbits of embedded SRAM with programmable FIFO control logic supports packet buffering and data staging on-chip.
• I/O Count & Standards — 138 user I/Os with support for high-speed differential interfaces; LVDS-capable channels rated up to 700 Mb/s as specified in the product family.
• Clocking & PLLs — Segmentable clock resources and embedded PLLs deliver flexible clocking and frequency synthesis to support system timing needs.
• Performance — Family-level system performance documented at 350+ MHz and internal performance up to 500+ MHz to support demanding logic and data-path throughput.
• Nonvolatile Antifuse Technology — Single-chip, nonvolatile programming with FuseLock™ technology to protect intellectual property and prevent reverse engineering.
• Power & Supply — Nominal 1.5 V core operation with specified supply range of 1.425 V to 1.575 V for core power.
• Package & Mounting — 256-LBGA (supplier 256-FPBGA, 17×17) in a surface-mount format for compact board-level integration.
• Commercial Temperature Grade — Rated for 0 °C to 70 °C operation; RoHS-compliant.
• Design & Test Support — Deterministic timing, boundary-scan (JTAG) and in-system diagnostic/debug capability with Microchip Silicon Explorer II as part of the Axcelerator family feature set.

Typical Applications

• High-speed data interfaces — Use the device’s LVDS-capable I/Os and embedded FIFOs for bridging and buffering between high-throughput serial or parallel links.
• Secure/Proprietary logic — Antifuse, nonvolatile programming and FuseLock™ protect designs that require secure bitstream storage and IP protection.
• ASIC replacement / Custom SOC glue logic — 250k gates and integrated memory enable migration of custom functions from ASICs to a reprogrammable FPGA architecture with ASIC-like performance.
• Deterministic real-time control — Segmentable clocks, PLL frequency synthesis and deterministic timing features support real-time logic and control applications requiring predictable timing.

Unique Advantages

• Single-chip nonvolatile solution: Antifuse technology provides permanent configuration without external flash, simplifying system boot and eliminating external configuration components.
• High internal throughput: Documented family-level internal performance up to 500+ MHz and system performance beyond 350 MHz enable dense, high-speed logic implementations.
• Protected intellectual property: FuseLock™ programming technology and antifuse programming reduce risk of reverse engineering for proprietary designs.
• Flexible on-chip memory: Embedded SRAM blocks with programmable FIFO control let you implement buffering and width-configurable memory without external RAM.
• Broad I/O capabilities: Mixed-voltage, bank-selectable I/Os and support for differential standards enable easy interfacing to a variety of system peripherals and high-speed links.
• Compact, surface-mount package: 256-LBGA (17×17) provides a small form factor for board-level space-constrained designs while supporting up to 138 user I/Os.
