AX250-1FG484

The AX250-1FG484 is a Microchip Axcelerator family antifuse FPGA based on the AX architecture. It provides a single-chip, nonvolatile programmable solution fabricated on a 0.15 µm CMOS antifuse process with seven layers of metal, delivering deterministic timing and hardware-level security for embedded designs.

Targeted at high-performance logic and I/O-centric applications, this commercial-grade device combines 250,000 equivalent gates, 4,224 logic elements, segmentable clock resources and embedded SRAM/FIFO capability to accelerate custom logic, high-speed interfaces and secure system functions.

Key Features

• Core Architecture  Antifuse-based AX architecture provides a nonvolatile single-chip solution with deterministic, user-controllable timing and FuseLock programming technology for protection against reverse engineering.
• Logic Resources  4224 logic elements (cells) and 250,000 equivalent system gates support midsize custom logic implementations and control functions.
• Embedded Memory & FIFOs  Approximately 0.055 Mbits of on-chip RAM (55,296 total bits) with embedded FIFO control logic and width-configurable read/write ports for data buffering and packet handling.
• I/O Capability  248 user I/Os with support for mixed-voltage operation and high-speed differential signaling (LVDS-capable up to 700 Mb/s as specified for the family).
• Clocking & Performance  Segmentable clock resources and on-chip PLLs support high internal performance (family-specified internal performance up to 500+ MHz and system performance above 350+ MHz).
• Power & Voltage  Core voltage specified from 1.425 V to 1.575 V to match system power budgets.
• Package & Mounting  484-ball fine-pitch BGA package (484-FPBGA, 23 × 23) for surface-mount PCB assembly with a compact footprint and high I/O density.
• Commercial Temperature Grade  Rated for 0 °C to 70 °C operation; RoHS-compliant manufacturing.

Typical Applications

• High-Speed Data Interfaces  Use the AX250-1FG484 for protocol bridging and custom PHY logic where LVDS-capable I/Os and high internal clocking support fast serial and parallel data paths.
• Custom Logic Acceleration  Implement application-specific processing, packet handling or control logic using the device’s 4,224 logic elements and embedded FIFOs to offload tasks from a host processor.
• Secure Embedded Systems  Leverage the antifuse nonvolatile architecture and FuseLock programming technology to protect IP and reduce risk of reverse engineering in secure designs.
• System Glue & Interface Integration  Ideal for consolidating multiple discrete components into a single programmable device to simplify board-level BOM and routing where mixed-voltage I/O support is required.

Unique Advantages

• Nonvolatile, One-Time Programmable Architecture: Antifuse technology provides a single-chip nonvolatile implementation that retains programmed logic without external configuration memory.
• Security by Design: FuseLock programming technology reduces exposure to reverse engineering and design theft for sensitive IP.
• High I/O Density in a Compact Package: 248 user I/Os in a 484-ball FPBGA (23 × 23) balance high connectivity with a compact footprint for space-constrained boards.
• Deterministic Timing and On-Chip Clocking: Segmentable clocks and embedded PLLs enable predictable timing and flexible frequency synthesis for demanding synchronous designs.
• Family-Level Performance: Family datasheet specifies system performance above 350 MHz and internal performance above 500 MHz, enabling designs that require high-speed internal logic and interfaces.
• RoHS-Compliant Manufacturing: Environmentally compliant production supports regulatory requirements for assembly and distribution.
