• Clock Management  Family-level clock features include up to four PLLs per device with five outputs per PLL, enabling flexible clock synthesis and distribution.
• Low-Power Family Characteristics  Cyclone III family devices are characterized for low static power consumption (family reference of less than ¼ watt static power), suitable for power-constrained designs.
• Supply Voltage  Core supply operating range: 1.15 V to 1.25 V, enabling compatibility with low-voltage system domains.
• Package & Mounting  484-FBGA package (supplier device package: 484-UBGA, 19×19) in a surface-mount form factor for compact PCB integration.
• Industrial Temperature  Rated for operation from −40 °C to 100 °C to meet demanding environmental requirements.
• I/O Standards & Signal Integrity (Family)  Cyclone III devices support a wide range of I/O standards (LVTTL, LVCMOS, SSTL, HSTL, PCI, LVDS, and others) and offer adjustable slew rates and on-chip termination calibration for robust interfaces.
• Security & Reliability (Family)  Series-level design security features and dedicated circuitry for configuration monitoring and SEU detection are included in the Cyclone III family.
• RoHS Compliant  Device meets RoHS requirements for reduced hazardous substances.

Typical Applications

• Industrial Control  Use the EP3C55U484I7 for PLC interfaces, motor control logic, and sensor aggregation where high I/O count and industrial temperature range are required.
• Embedded Processing & Offload  Leverage on-chip memory and logic capacity to implement custom accelerators, protocol offload, or embedded-processing functions alongside soft-core processors supported by the Cyclone III family.
• Communications & Connectivity  Implement protocol bridging, interface serialization/deserialization, and multi-protocol I/O with abundant user I/Os and flexible clocking resources.
• High-Volume, Low-Power Systems  Deploy in volume-sensitive products where low static power and cost-efficient FPGA integration reduce BOM and thermal management needs.

Unique Advantages

• Substantial Logic Capacity:  55,856 logic elements enable complex state machines, DSP pipelines, and glue logic without partitioning across multiple devices.
• Compact, High-Pin Package:  484-FBGA (19×19) provides a dense I/O footprint in a compact surface-mount form factor for space-constrained PCBs.
• Industrial Reliability:  −40 °C to 100 °C operating range and RoHS compliance make the device suitable for harsh environments and long-term production use.
• Integrated Clocking:  Multiple PLLs with cascaded and reconfigurable outputs simplify clock domain creation and jitter management for complex interfaces.
• Family-Level Power Efficiency:  Cyclone III family optimizations and low-power process characteristics support lower static power budgets for battery-powered or thermally constrained systems.
• Flexible I/O Signal Support:  Support for a broad set of I/O standards and on-chip termination calibration improves signal integrity across mixed-voltage systems.
