Overview
The EP2C5T144C7 is a mid-range FPGA from Intel's Cyclone II family, designed for cost-sensitive applications requiring moderate logic density. It is fabricated using 90nm CMOS technology and offers a balance of performance, power efficiency, and reprogrammability. With 5,136 logic elements (LEs) and 119 Kbits of embedded memory, it suits prototyping, motor control, and signal processing tasks. The 144-pin Thin Quad Flat Pack (TQFP) package ensures compatibility with standard PCB designs while minimizing footprint.
Structure and Working Principle
The FPGA consists of configurable logic blocks (LABs), embedded memory blocks (M4K), and phase-locked loops (PLLs) for clock management. Each LAB contains 16 logic elements, which can implement combinational or sequential logic. Users program the device via Hardware Description Languages (HDL) like VHDL or Verilog, defining interconnections between logic elements. Upon power-up, the configuration is loaded from an external flash memory, enabling dynamic reconfiguration for design iterations.
Key Features
The EP2C5T144C7 supports up to 113 user I/O pins with LVCMOS, LVTTL, and other I/O standards, offering flexibility for interfacing with peripheral devices. Its embedded PLLs allow clock multiplication/division for precise timing control. Notably, it consumes as low as 12 mA in standby mode, making it suitable for battery-powered systems. The device operates across industrial temperature ranges (-40°C to 100°C), ensuring reliability in harsh environments.
Application Areas
Common applications include industrial automation (PLC, HMI), telecommunications (protocol bridging), and consumer electronics (display controllers). Its reprogrammability accelerates development cycles for IoT edge devices. In automotive systems, it serves as a glue logic for sensor interfacing. Medical equipment manufacturers use it for customizable control logic in portable diagnostic tools, leveraging its low EMI characteristics.
Maintenance and Precautions
Avoid exposing the FPGA to electrostatic discharge (ESD) during handling; use grounded workstations and anti-static packaging. Ensure stable power supply within 3.0V–3.6V for the core voltage (VCCINT) to prevent latch-up. For long-term storage, maintain humidity below 60% and temperature below 40°C. Periodically update firmware to address potential security vulnerabilities in deployed systems.
B2B Procurement Guide
When procuring EP2C5T144C7 FPGAs, verify the supplier's authorization status with Intel to avoid counterfeit components. Request production date codes to ensure fresh stock, as prolonged shelf life may affect solderability. Consider purchasing evaluation kits (e.g., Cyclone II Starter Kit) for prototyping. For high-volume orders (1,000+ units), negotiate pricing tiers and lead times—typically 6–8 weeks for non-stock quantities. Always confirm RoHS compliance for environmental regulations.
