Key Features

• Core Architecture  Approximately 20,000 logic elements and 2,464 logic blocks for implementing medium-to-large FPGA designs.
• Embedded Memory  Approximately 0.396 Mbits of on-chip RAM (EBR and distributed memory) to support data buffering and local storage.
• High I/O Count  Up to 340 I/O pins to accommodate broad connectivity requirements in a single device.
• Non-Volatile, Instant-On Operation  Built-in non-volatile configuration removes the need for external configuration memory and allows the device to power up in microseconds.
• In-Field Reconfiguration (TransFR™)  Supports in-system reconfiguration while the system operates, enabling logic updates without removing the device from the board.
• Low-Power Sleep Mode  Sleep mode delivers substantial static current reduction for power-sensitive applications.
• Flexible I/O Buffering  Programmable I/O supports a wide range of standards, enabling interfacing with multiple signaling families and system voltage levels.
• Dedicated DDR Memory Support  Implements interfaces up to DDR333 for system memory connectivity.
• Clocking  Up to four analog PLLs for clock multiply, divide and phase shifting.
• Package & Mounting  484-ball BBGA surface-mount package (supplier package: 484-FPBGA, 23 × 23 mm) for compact board integration.
• Power & Temperature  Operates across a supply range of 1.71 V to 3.465 V and a commercial operating temperature range of 0 °C to 85 °C.
• Compliance  RoHS compliant.

Typical Applications

• Embedded Systems  Implement custom processing, control logic and peripheral interfaces using the device’s reconfigurable logic and on-chip memory.
• Interface Bridging & Protocol Conversion  Leverage 340 I/Os and programmable I/O standards to bridge disparate interfaces and perform protocol translation on a single device.
• Memory Interface Controllers  Use the dedicated DDR memory support and on-chip RAM for implementing memory controllers and high-speed buffering.
• Field Upgradeable Systems  Take advantage of in-field TransFR reconfiguration to deploy updates and feature changes without board-level replacements.

Unique Advantages

• Instant-on, non-volatile configuration: Eliminates external configuration memory and enables fast power-up behavior for systems that require immediate availability.
• In-field reconfiguration capability: TransFR™ allows logic updates while the system remains in operation, reducing maintenance downtime and enabling agile feature updates.
• High integration density: 20,000 logic elements and substantial on-chip RAM reduce external component count and simplify board-level design.
• Flexible I/O and clocking: Extensive I/O support and up to four PLLs enable diverse interface implementations and precise clock management within the same device.
• Commercial-grade robustness: Qualified for 0 °C to 85 °C operation and a wide supply voltage window (1.71 V–3.465 V) to suit a range of commercial designs.
• RoHS compliant: Meets environmental compliance requirements for modern electronic assemblies.
