Designed for commercial-temperature applications, this device targets designs that require a balance of logic capacity, embedded RAM, and a compact surface-mount package.

Key Features

• Logic Resources  4,608 configurable logic blocks (CLBs) delivering a total of 41,472 logic elements for implementing complex digital functions and custom pipelines.
• Embedded Memory  Approximately 1.77 Mbits of on-chip RAM to support buffering, FIFOs and small data stores without external memory.
• I/O Capacity  448 user I/Os to interface with multiple peripherals, busses and parallel interfaces from a single device.
• Package and Mounting  668-ball FCBGA (27 × 27 mm) surface-mount package for compact board integration and high pin-count designs.
• Power  Core supply voltage range of 1.14 V to 1.26 V to align with regulated core-power rail designs.
• Operating Range  Commercial temperature grade rated for 0 °C to 85 °C.
• Compliance  RoHS compliant for lead-free assembly and regulatory alignment in commercial products.

Typical Applications

• Custom Digital Logic  Implement application-specific datapaths, state machines and protocol engines using the device's extensive logic and I/O resources.
• Prototyping and Development  Use the reprogrammable logic and embedded RAM for hardware validation, algorithm acceleration, and iterative design refinement.
• High‑I/O Interface Concentration  Consolidate multiple parallel and serial interfaces into a single FPGA for system integration and I/O bridging tasks.

Unique Advantages

• High Logic Density: 41,472 logic elements allow implementation of substantial digital functionality without partitioning across multiple devices.
• Significant On‑Chip Memory: Approximately 1.77 Mbits of embedded RAM reduces dependence on external memory for many control and buffering tasks.
• Large I/O Count: 448 user I/Os simplify board-level routing when interfacing with multiple subsystems or wide parallel buses.
• Compact FCBGA Package: 668-ball, 27 × 27 mm FCBGA package offers a high-pin-count solution in a compact footprint for dense PCB layouts.
• Narrow Core Voltage Range: Defined 1.14 V–1.26 V core supply window supports predictable power-supply design and regulation choices.
• RoHS Compliant: Meets lead-free assembly requirements for commercial product manufacturing.
