EP1C20F400C6

Overview

The EP1C20F400C6 is a member of Intel's (formerly Altera) Cyclone FPGA family, designed for cost-sensitive, high-volume applications. This FPGA offers a balance between performance and power efficiency, making it suitable for various digital design projects. With 20,000 logic elements (LEs) and 400-pin FineLine BGA packaging, this device provides substantial programmable logic resources while maintaining a compact footprint. The 'C6' speed grade indicates moderate performance characteristics suitable for many industrial and commercial applications.

Structure and Working Principle

深圳市金凯电子科技有限公司

The EP1C20F400C6 consists of an array of configurable logic blocks (CLBs), embedded memory blocks, phase-locked loops (PLLs), and programmable I/O elements. These components are interconnected through a flexible routing architecture that can be programmed to implement custom digital circuits. When powered on, the device loads its configuration from an external memory (typically flash) to define the logic functions and interconnections. The FPGA then operates as a custom hardware implementation of the designed digital logic, offering hardware-level performance for the specified application.

Proper handling of the EP1C20F400C6 requires ESD (electrostatic discharge) precautions at all times. Use grounded workstations and wrist straps when handling the device to prevent damage from static electricity. Ensure power supply voltages remain within specified limits (typically 1.425V to 1.575V for core voltage). Thermal management is important in high-performance applications - monitor operating temperatures and provide adequate cooling if necessary.

B2B Procurement Guide

When procuring EP1C20F400C6 FPGAs in bulk, verify the supplier's authorization with Intel/Altera to ensure genuine components. Consider lead times, as FPGA availability can vary significantly in the semiconductor market. Evaluate whether you need commercial (0°C to 85°C) or industrial (-40°C to 100°C) temperature grade devices based on your application environment. For long-term projects, assess the device's lifecycle status to avoid obsolete components.
