EP3C55U484C7N

The EP3C55U484C7N is a Cyclone III field-programmable gate array (FPGA) in a 484-FBGA package designed for high-volume, low-power, cost-sensitive applications. Built on the Cyclone III device family architecture, it combines a high logic count and on-chip memory with robust I/O capacity and low static power characteristics.

This device is suited to commercial applications that require substantial programmable logic, significant embedded memory, and broad interfacing options while operating within a 0 °C to 85 °C commercial temperature range and a 1.15 V to 1.25 V core supply window.

Key Features

• Logic Capacity — 55,856 logic elements provide a large programmable fabric for customized digital logic, signal processing, and control functions.
• Embedded Memory — Approximately 2.4 Mbits of on-chip RAM for buffering, FIFOs, and local data storage to reduce external memory requirements.
• I/O and Packaging — 327 user I/Os in a 484-FBGA (484-UBGA, 19×19) footprint; surface-mount package suitable for dense PCB layouts.
• Low-Power Architecture — Cyclone III family optimizations and TSMC low-power process enable low static power consumption (family reference to less than ¼ watt static power), helping extend battery life and reduce cooling needs.
• Clock Management — Four phase-locked loops (PLLs) per device give flexible clock synthesis and management for internal logic and external interfaces.
• Voltage and Thermal Range — Core supply 1.15 V to 1.25 V and operating temperature 0 °C to 85 °C (commercial grade) to match typical commercial system environments.
• Design Ecosystem — Cyclone III family includes support for embedded processing and a library of pre-built IP cores and design tools (family-level capability) to accelerate development.
• Compliance — RoHS compliant for broad regulatory compatibility in commercial product assemblies.

Typical Applications

• Portable and Handheld Devices — Low static power and the Cyclone III low-power design help extend battery life while providing significant programmable logic for device control and signal handling.
• Communications and Networking — High logic density, on-chip RAM, and multiple PLLs enable protocol processing, packet buffering, and clock domain management.
• Consumer Electronics — Large I/O count and flexible packaging support display interfaces, sensor aggregation, and user-interface control in compact commercial products.
• Embedded Control and Processing — On-chip memory and family-level support for embedded processors and IP cores make this device suitable for control, data acquisition, and system orchestration tasks.

Unique Advantages

• High Integration: 55,856 logic elements and approximately 2.4 Mbits of embedded memory reduce the need for external logic and memory components, simplifying BOM and board layout.
• Large I/O Count: 327 I/Os in a compact 484-FBGA package provide flexible interfacing for multi-signal systems and high-density connectors.
• Power-Efficient Operation: Family-level low-power process and silicon optimizations support low static power consumption, helping lower system power budgets.
• Robust Clocking: Four PLLs per device enable complex clocking schemes, frequency synthesis, and jitter management without additional external components.
• Commercial Temperature Suitability: Qualified for 0 °C to 85 °C operation, aligning with typical commercial product requirements.
• Design Acceleration: Cyclone III family support for pre-built IP and development tools helps shorten development cycles and enable reuse across projects.
