• Power and Core Supply  Core voltage supply range of 1.15 V to 1.25 V to match platform power requirements.
• Clock Management  Cyclone III family devices provide four phase-locked loops (PLLs) per device for clock synthesis and management.
• Package & Mounting  484-FBGA (supplier package: 484-UBGA, 19×19) in a surface-mount format for compact PCB integration.
• Operating Range & Grade  Commercial grade operation from 0 °C to 85 °C to suit mainstream electronics and embedded systems.
• Standards & Integration  Cyclone III family architecture supports a wide range of I/O standards and system integration features (family-level capabilities).
• Environmental  RoHS compliant.

Typical Applications

• Consumer and Portable Electronics  Implement custom peripheral logic, interface bridging, and system glue in products where low power and density around 39,600 logic elements are required.
• Communications Equipment  Handle protocol adaptation, packet buffering, and I/O aggregation using the device’s high I/O count and embedded memory.
• Industrial Control  Provide flexible control logic and real-time interfacing for equipment operating within commercial temperature limits.
• Video and Imaging  Support preprocessing and timing control tasks leveraging the device’s logic capacity and clock management features.

Unique Advantages

• High Integration: Consolidate multiple discrete functions into a single FPGA with ~39,600 logic elements and on-chip memory to reduce BOM and board complexity.
• Flexible I/O Availability: 331 user I/Os enable broad peripheral and bus connectivity without external multiplexing.
• Compact BGA Footprint: 484-FBGA packaging offers a small PCB footprint for space-constrained designs while maintaining routing density.
• Low-Voltage Core: A narrow core supply range (1.15–1.25 V) helps integration with modern low-voltage power architectures.
• Family-Level Low Power: Cyclone III family attributes emphasize low static power and system-level power efficiency for battery- or heat-constrained applications.
• Commercial Temperature Support: Rated 0 °C to 85 °C for mainstream electronic and embedded applications.
