Key Features

• Logic Capacity — Provides 48,000 logic elements supported by 6,000 CLBs to implement custom digital functions and parallel processing pipelines.
• Embedded Memory — Approximately 0.396 Mbits of on-chip RAM (396,288 bits) for buffering, FIFOs, and small-data storage without external memory.
• I/O Density — 339 user I/Os to interface with sensors, peripherals, transceivers, and board-level peripherals.
• Package & Mounting — Supplied in a 484-ball BBGA package (supplier package: 484-FPBGA, 23 × 23) for high-density board integration; surface-mount mounting type.
• Power — Core supply operating range of 1.14 V to 1.26 V for defined power domain planning.
• Industrial Temperature Range — Rated for operation from −40°C to 100°C, supporting deployment in industrial and harsh-temperature environments.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Industrial Control Systems — Use the FPGA to implement custom motor control, PLC logic, and real-time signal processing functions that benefit from the device’s 48,000 logic elements and extended temperature rating.
• Embedded Networking & Interfaces — Leverage 339 I/Os to bridge and implement protocol conversion, multi‑lane interfaces, and glue logic between heterogeneous sub-systems.
• Data Acquisition & Signal Conditioning — Deploy on-chip memory and dense logic resources for aggregation, buffering, and pre-processing of sensor data in industrial measurement applications.

Unique Advantages

• Large Logic Footprint: 48,000 logic elements enable complex custom hardware acceleration and parallel processing without immediate need for larger devices.
• High I/O Count: 339 I/Os simplify board-level routing and reduce the need for external multiplexing or expanders.
• Embedded RAM Availability: Approximately 0.396 Mbits of on-chip RAM provides space for buffering and local data storage, reducing external memory dependency for many applications.
• Industrial Temperature Support: −40°C to 100°C rating supports deployment in industrial environments where extended temperature operation is required.
• Compact, High-Density Packaging: 484-BBGA (23 × 23 FPBGA supplier package) balances pin count and board-area efficiency for space-constrained designs.
• Regulatory Compliance: RoHS compliance supports use in products targeting restricted-substance requirements.
