AX250-FG256I

The AX250-FG256I is a Microchip Axcelerator antifuse FPGA based on the AX architecture, offering a single‑chip, nonvolatile programmable logic solution. This industrial‑grade device provides 250,000 equivalent system gates and is built for designs that require secure, high‑performance programmable logic with integrated memory, PLLs and flexible I/O.

Designed on a 0.15 μm CMOS antifuse process with seven metal layers, the device supports deterministic timing and in‑system diagnostic capabilities while operating over an industrial temperature range and a 1.425–1.575 V core supply.

Key Features

• Logic Capacity — 250,000 equivalent system gates and 4,224 logic elements (cells) to implement complex logic and control functions.
• Embedded Memory & FIFOs — 55,296 bits of embedded RAM (approximately 0.055 Mbits) with embedded FIFO control logic for buffering and data staging inside the FPGA.
• I/O Resources — 138 user I/Os with multi‑standard I/O capability (mixed voltages supported at the family level) and LVDS‑capable interfaces up to 700 Mb/s.
• Performance — Family‑level performance metrics include 350+ MHz system performance and 500+ MHz internal performance; the family also provides high‑performance embedded FIFOs and PLL frequency synthesis.
• Programmability & Security — Antifuse, single‑chip nonvolatile programming and FuseLock programming technology to protect against reverse engineering and design theft.
• Clocking & Timing — Segmentable clock resources and on‑chip PLLs with frequency synthesis capability; deterministic, user‑controllable timing for predictable system behavior.
• Package & Mounting — 256‑LBGA package (supplier package: 256‑FPBGA, 17 × 17) for surface‑mount assembly; compact footprint compatible packaging.
• Industrial Grade & Environmental — Rated for operation from −40 °C to 85 °C and RoHS compliant.
• Power — Core supply range of 1.425 V to 1.575 V (nominal 1.5 V core voltage referenced at the family level) for low‑voltage operation.

Typical Applications

• High‑performance embedded systems — Use the device to accelerate compute‑intensive control or data‑path functions with dense logic and embedded memory.
• Secure, nonvolatile programmable logic — Antifuse programming and FuseLock protect IP in applications where design security and one‑time programmable configurations are required.
• I/O‑intensive interfaces — Leverage 138 I/Os and LVDS‑capable channels to implement mixed‑voltage interface bridging, serial links and high‑speed connectivity.
• Industrial control and instrumentation — Industrial temperature rating and deterministic timing make the device suitable for control, data acquisition and deterministic signal processing tasks.

Unique Advantages

• Nonvolatile, secure configuration: Antifuse technology and FuseLock programming provide a one‑time programmable, tamper‑resistant configuration for IP protection.
• Embedded RAM and FIFO support: On‑chip memory with configurable FIFO control simplifies buffer management and reduces external memory dependencies.
• Deterministic timing and clock flexibility: Segmentable clocks and on‑chip PLLs enable predictable timing and flexible clocking topologies for tightly constrained designs.
• Compact surface‑mount packaging: 256‑LBGA (256‑FPBGA supplier package) delivers a compact footprint for space‑constrained boards while maintaining ample I/O.
• Industrial operating range: −40 °C to 85 °C operation ensures suitability for a wide range of industrial environments.
• Vendor diagnostic support: In‑system diagnostic and debug capability is provided at the family level for streamlined bring‑up and validation.
