Key Features

• Core Capacity — 33,000 logic elements provide significant on-chip programmable logic resources for implementing complex digital functions.
• Embedded Memory — Approximately 1.36 Mbits (1,358,848 bits) of on-chip RAM to support data buffering, state storage, and small lookup tables.
• I/O Density — 295 I/O pins to support multiple parallel interfaces, external device control, and board-level system integration.
• Power Supply — Operates from a core voltage range of 1.14 V to 1.26 V for compatibility with low-voltage system domains.
• Package and Mounting — Available in a 484-FPBGA (23×23) / 484-BBGA package and designed for surface-mount assembly to save PCB area.
• Operating Range — Commercial temperature grade with an operating range of 0 °C to 85 °C.
• Environmental Compliance — RoHS compliant to meet standard environmental requirements.

Typical Applications

• Logic-dense digital prototypes — Use the 33,000 logic elements to implement and validate complex digital functions and subsystems.
• I/O-intensive interface bridging — 295 I/Os allow the FPGA to serve as a central hub for multiple parallel and serial connections.
• Memory-assisted processing — Approximately 1.36 Mbits of embedded RAM supports buffering, packet handling, and state machines within a single device.
• Compact board-level solutions — The 484-FPBGA (23×23) package and surface-mount mounting enable space-efficient PCB designs.

Unique Advantages

• High on-chip logic capacity: 33,000 logic elements reduce the need for external glue logic and simplify system partitioning.
• Substantial embedded memory: Approximately 1.36 Mbits of RAM supports local data storage and on-chip buffering to improve system responsiveness.
• Extensive I/O availability: 295 I/O pins provide flexibility for connecting sensors, peripherals, and multiple interfaces without additional chips.
• Compact BGA footprint: 484-FPBGA (23×23) packaging provides a high-pin-count solution in a board-area-efficient form factor.
• Low-voltage core operation: 1.14–1.26 V supply range aligns with modern low-voltage system designs.
• Commercial-grade and RoHS compliant: Rated for 0 °C to 85 °C operation and RoHS compliant for standard commercial product deployments.
