• Performance  Family‑level performance characteristics include 350+ MHz system performance and 500+ MHz internal performance; high‑performance embedded FIFOs and LVDS‑capable I/Os.
• Clocking and PLLs  Segmentable clock resources and embedded PLLs (family features) with an input range of 14–200 MHz and frequency synthesis capability up to 1 GHz.
• Power and Package  Core supply 1.425–1.575 V (nominal 1.5 V), surface‑mount 256‑LBGA (256‑FPBGA 17×17) package suitable for compact board designs.
• Industrial Grade and Compliance  Specified for −40 °C to 85 °C operation and RoHS‑compliant.
• Security and Design Protection  FuseLock programming technology in the Axcelerator family provides protection against reverse engineering and design theft.

Typical Applications

• High‑speed interface bridging  Use the device to implement protocol conversion, lane alignment, and buffering between high‑speed serial or parallel interfaces leveraging embedded FIFOs and LVDS‑capable I/Os.
• Industrial control and instrumentation  Implement deterministic control logic, sensor aggregation, and real‑time processing within industrial temperature ranges.
• Packet buffering and data path processing  Embedded RAM blocks and FIFO control logic support temporary packet storage, queuing, and data flow management in communication or data acquisition systems.
• Security‑sensitive hardware designs  One‑time programmable antifuse technology and FuseLock help protect intellectual property in secure or tamper‑sensitive applications.

Unique Advantages

• Nonvolatile, one‑time programmable solution: Antifuse architecture provides single‑chip, nonvolatile configuration—eliminating the need for external configuration memory.
• Deterministic timing and controllability: AX architecture features allow user‑controllable timing for designs that require predictable behavior.
• Integrated clocking and PLLs: Embedded PLLs and segmentable clocks simplify clock management for multi‑domain and high‑frequency designs.
• Embedded FIFOs and RAM: On‑chip memory and FIFO control reduce external memory dependencies for buffering and packet handling.
• Industrial temperature range: Specified operation from −40 °C to 85 °C for reliability in industrial environments.
• Design protection with FuseLock: Built‑in programming security minimizes risk of reverse engineering or unauthorized design copying.
