EP3C55U484C6

The EP3C55U484C6 is a Cyclone® III family FPGA optimized for low-power, high-functionality designs. Built on the Cyclone III architecture, it targets high-volume, cost-sensitive commercial applications that require substantial programmable logic, a large on-chip memory footprint, and a high I/O count.

This device combines 55,856 logic elements with approximately 2.4 Mbits of embedded memory and 327 I/O pins in a compact 484‑FBGA package, delivering a flexible, low-voltage programmable platform for embedded processing, interface bridging, and system integration tasks.

Key Features

• Core and Logic Density — 55,856 logic elements provide ample programmable logic capacity for complex custom functions and system integration.
• Embedded Memory — Total on-chip RAM of 2,396,160 bits (approximately 2.4 Mbits) for buffering, FIFOs, and lookup tables.
• I/O and Package — 327 I/O pins in a 484‑FBGA package (supplier package: 484‑UBGA, 19×19); surface-mount mounting for compact PCB integration.
• Low-Voltage Operation — Specified supply range of 1.15 V to 1.25 V to support low-power system designs.
• Commercial Temperature Grade — Rated for 0 °C to 85 °C operation for standard commercial applications.
• Clock Management — Family-level clocking resources include four phase-locked loops (PLLs) with multiple outputs and dynamic reconfiguration capability for flexible clock synthesis and distribution.
• Low-Power Family Architecture — Cyclone III family emphasizes low power through TSMC low-power process technology and silicon/software optimizations, helping to extend battery life and reduce system cooling requirements.
• System Reliability and Diagnostics — Family features include error-detection circuitry to monitor configuration memory integrity and detect single-event upsets (SEUs).
• Embedded Processing and IP — Supports the Cyclone III family’s ecosystem, including the Nios® II embedded processor and a broad collection of pre-built, verified IP cores.
• RoHS Compliant — Device is RoHS compliant.

Typical Applications

• High-volume, cost-sensitive consumer products — Use the device where low power and low cost are priorities while retaining significant programmable logic and memory resources.
• Portable and battery-powered systems — Low-voltage architecture and family-level low-power optimizations help extend battery life in handheld and portable designs.
• Embedded processing and custom peripherals — Integrate Nios® II soft processors and pre-built IP to implement application-specific control, protocol handling, or preprocessing functions.
• Interface and I/O-heavy systems — High I/O count and flexible I/O standards on the Cyclone III family make the device suitable for designs requiring extensive external interfacing.

Unique Advantages

• Significant logic capacity: 55,856 logic elements enable dense custom logic and feature integration on a single device, reducing BOM complexity.
• Substantial on-chip memory: Approximately 2.4 Mbits of embedded RAM supports buffering, packet processing, and local data storage without external memory.
• High I/O in a compact footprint: 327 I/Os in a 484‑FBGA (484‑UBGA, 19×19) package delivers broad connectivity while conserving PCB area.
• Low-voltage, power-aware operation: 1.15–1.25 V supply range and Cyclone III low-power design features help minimize system power consumption.
• Flexible clocking and reconfiguration: Multiple PLLs with dynamic reconfiguration provide robust clock management for diverse subsystems and interfaces.
• Established ecosystem: Access to Nios® II soft-core support and a wide selection of pre-verified IP cores accelerates development and reduces time-to-market.
