AX250-2FGG256I

The AX250-2FGG256I is an Axcelerator family FPGA from Microchip Technology, offering a nonvolatile, antifuse-based programmable logic solution with approximately 250,000 equivalent system gates. It combines high-performance logic, embedded memory and flexible I/O to support systems that require deterministic timing, embedded FIFO buffering and multi-standard interface capability.

With 4,224 logic elements, about 55.3 kbits of embedded RAM, 138 user I/Os and on-chip PLL resources, this device targets applications needing high internal throughput, secure programming and industrial temperature operation.

Key Features

• Core Capacity — Approximately 250,000 equivalent system gates realized across 4,224 logic elements for mid-density programmable logic.
• Embedded Memory & FIFOs — Total on-chip RAM of 55,296 bits with embedded FIFO control logic and variable-aspect RAM blocks for flexible buffering and data-path width configurations.
• I/O Flexibility — 138 user I/Os with support for mixed-voltage operation (1.5V, 1.8V, 2.5V and 3.3V) and high-speed differential capability (LVDS, 700 Mb/s capable).
• High-Speed Timing — Device family-level performance includes 350+ MHz system performance and 500+ MHz internal performance; on-chip PLLs provide frequency synthesis and clock management (14–200 MHz input range, synthesis up to 1 GHz).
• Secure, One-Time Programmable Technology — Antifuse-based, single-chip nonvolatile solution with FuseLock programming technology to protect against reverse engineering and unauthorized readback.
• Deterministic Design & Debug — Deterministic, user-controllable timing, boundary-scan testing (IEEE 1149.1/JTAG) and in-system diagnostic/debug capability via Microchip Silicon Explorer II.
• Power & Package — Core voltage supply range of 1.425 V to 1.575 V, surface-mount 256-LBGA package (supplier package 256-FPBGA, 17×17 mm footprint), and RoHS-compliant construction.
• Industrial Temperature — Rated for operation from −40 °C to +85 °C for industrial application environments.

Typical Applications

• High-speed serial interfaces — LVDS-capable I/Os and on-chip PLLs enable implementation of differential serial links and protocol bridging where multi-gigabit-equivalent timing synthesis is required.
• Embedded buffering and packet processing — Built-in FIFO control logic and 55,296 bits of embedded RAM simplify packet buffering, width conversion and real-time data staging.
• Custom logic and ASIC replacement — Mid-density logic (≈250k gates) and flexible I/O standards support migration of custom glue logic and application-specific functions into a single nonvolatile device.
• Industrial control and communications — Industrial temperature rating, mixed-voltage I/O and deterministic timing make the device suitable for control, protocol conversion and communications front-ends in industrial systems.

Unique Advantages

• Single-chip nonvolatile solution: Antifuse architecture provides one-time programmable, nonvolatile implementation—no external configuration memory required.
• Secure programmability: FuseLock protection reduces risk of reverse engineering and IP exposure for deployed designs.
• Flexible I/O standards: Bank-selectable, multi-voltage I/Os and supported differential standards enable broad interface compatibility without external level shifters.
• On-chip timing synthesis: Embedded PLLs and segmentable clock resources deliver frequency synthesis and deterministic, user-controllable timing for high-performance systems.
• Integrated debugging and test: In-system diagnostics with Silicon Explorer II and IEEE 1149.1 boundary-scan support simplify development and manufacturing test flows.
• Industrial-grade thermal range and RoHS compliance: Rated −40 °C to +85 °C and RoHS-compliant for deployment in industrial environments.
