• Clocking & PLLs: Segmentable clock resources and embedded PLLs with a 14–200 MHz input range and frequency synthesis capabilities up to 1 GHz enable flexible clocking and high-frequency operation.
• Power & Supply: Core supply specified at 1.425 V to 1.575 V (nominal 1.5 V core) for low-power core operation.
• Package & Mounting: Surface-mount 484-ball fine-pitch BGA (484-FPBGA, 23 × 23) package suitable for compact board-level integration.
• Reliability & Security: Single-chip, nonvolatile antifuse solution with FuseLock programming technology to protect against reverse engineering, plus JTAG boundary-scan testing (IEEE 1149.1) for testability.
• Industrial Temperature Grade: Rated for operation from −40 °C to +85 °C and RoHS compliant for environmental compatibility.

Typical Applications

• High-speed data interfaces: LVDS-capable I/Os and embedded FIFOs enable robust handling of serial and parallel high-throughput links and protocol bridging.
• Secure embedded systems: Antifuse nonvolatile programming and FuseLock technology help protect sensitive logic and IP in security-conscious applications.
• Communications and networking: Integrated PLLs, segmentable clocks and abundant I/O support system timing and interface requirements for networking equipment and telecom modules.
• Custom logic and system integration: Large logic element count and on-chip RAM make the device suitable for replacing or prototyping ASIC functionality in embedded designs.

Unique Advantages

• Nonvolatile single-chip solution: Antifuse programming provides persistent configuration without external configuration memory, simplifying system boot and security.
• High-performance timing: Documented internal and system frequency capabilities plus embedded PLLs enable high-speed designs with deterministic timing.
• Flexible I/O and mixed-voltage support: Bank-selectable I/Os and multiple supported I/O standards reduce the need for level-shifting and expand interface options.
• Embedded FIFOs and configurable RAM: On-chip RAM blocks with programmable FIFO control streamline data buffering and width conversions without external memory.
• Design security features: FuseLock programming technology and a nonvolatile antifuse process help protect intellectual property against reverse engineering.
• Industrial temperature operation: Rated for −40 °C to +85 °C, suitable for industrial-grade deployments requiring wider operating temperature ranges.
