Overview
The EP2C50F484I7N is a member of Intel's Cyclone II FPGA family, designed for flexibility and performance in embedded systems. It integrates 50,000 logic elements, 1.1Mbits of embedded memory, and 315 user I/O pins, supporting high-speed interfaces like PCI and DDR. Its reconfigurable architecture makes it suitable for prototyping and production across industries such as telecommunications, automotive, and industrial automation. This FPGA operates at a core voltage of 1.2V and offers a balance of power efficiency and computational capability. The industrial-grade variant (I7N) ensures reliability in harsh environments, with an operating temperature range of -40°C to 100°C. Its compact 484-pin FineLine BGA package optimizes space in dense PCB layouts.
Structure and Working Principle
The EP2C50F484I7N consists of configurable logic blocks (CLBs), embedded memory blocks, and digital signal processing (DSP) units interconnected via a programmable routing matrix. Each CLB contains look-up tables (LUTs) and flip-flops, enabling custom logic implementation. The embedded memory supports single- and dual-port RAM configurations, while the DSP blocks accelerate arithmetic operations. During operation, the FPGA is programmed via a bitstream file, which defines the circuit's behavior. This reconfigurability allows for post-deployment updates, reducing time-to-market for iterative designs. The device interfaces with external components through its 315 I/O pins, which support standards like LVDS and LVCMOS.
Key Features
The EP2C50F484I7N stands out for its high logic density (50,000 elements) and low static power consumption, making it energy-efficient for continuous operation. Its 1.1Mbits of embedded memory eliminates the need for external storage in many applications, reducing system complexity. The industrial-grade temperature range ensures reliability in extreme conditions. Notably, the FPGA supports partial reconfiguration, enabling dynamic updates to specific circuit sections without disrupting overall functionality. Its 315 I/O pins provide ample connectivity for peripherals, sensors, and communication modules. The inclusion of PLLs (Phase-Locked Loops) allows precise clock management, critical for synchronous designs.
Application Areas
This FPGA is widely used in industrial automation for motor control and PLCs (Programmable Logic Controllers), leveraging its real-time processing capabilities. In telecommunications, it facilitates signal modulation and protocol handling in base stations and networking equipment. Automotive systems employ it for ADAS (Advanced Driver Assistance Systems) and infotainment due to its robustness. Additional applications include medical imaging devices, where its DSP blocks accelerate algorithms, and military/aerospace systems requiring radiation-tolerant designs. Its flexibility also makes it popular in academic research and prototyping, enabling rapid iteration of digital circuits.
Maintenance and Precautions
To ensure longevity, avoid exposing the EP2C50F484I7N to voltages exceeding 1.2V on core pins or 3.3V on I/O pins. Use ESD (electrostatic discharge) protection during handling and assembly. Thermal management is critical; adhere to the specified junction temperature limit of 125°C to prevent silicon degradation. For firmware updates, validate bitstream files in a test environment before deployment. Regularly monitor power supply stability, as voltage fluctuations can cause configuration errors. When designing PCB layouts, follow Intel's guidelines for signal integrity, especially for high-speed differential pairs like LVDS.
B2B Procurement Guide
When sourcing the EP2C50F484I7N, verify the supplier's authorization to avoid counterfeit parts. Industrial-grade variants (I7N) are recommended for harsh environments, while commercial-grade (C7N) suits benign conditions. Lead times can vary; bulk orders (100+ units) often reduce per-unit costs by approximately 15–20%. Evaluate alternatives like the EP4CE series for newer designs requiring higher performance. Request samples for testing compatibility with existing systems. Key distributors include Arrow Electronics, Avnet, and Intel Direct. Check for RoHS compliance if environmental regulations apply.
