Key Features

• Programmable Logic  Approximately 67,000 logic elements to implement complex logic, state machines and custom datapaths.
• Embedded Memory  Approximately 4.53 Mbits of on-chip RAM for buffering, FIFOs and local data storage without immediate need for external memory.
• I/O Density  295 I/O pins to support multiple parallel interfaces, peripheral connections and board-level signal routing.
• Package  484-ball BGA package (supplier package: 484-FPBGA, 23×23 mm footprint) optimized for high-density board layouts.
• Power  Core supply range of 1.14 V to 1.26 V to match system power-rail planning and low-voltage digital domains.
• Temperature and Grade  Industrial-grade device rated for operation from −40 °C to 100 °C for deployment in demanding environments.
• Mounting and Compliance  Surface mount package and RoHS compliant for modern manufacturing and environmental requirements.

Typical Applications

• Industrial Control  Leverages the industrial temperature range, substantial logic resources and high I/O count for motor control, programmable automation and sensor interfacing.
• Communications and Networking  High I/O density and on-chip RAM enable protocol bridging, packet buffering and custom interface logic.
• Signal Processing  Embedded memory and large logic capacity support data path implementation, streaming logic and pre/post-processing tasks.

Unique Advantages

• Highly integrated logic and memory: The combination of ~67,000 logic elements and approximately 4.53 Mbits of embedded RAM reduces dependence on external components and simplifies board design.
