INDUSTRY COMPONENT

Configurable Logic Block (CLB)

A programmable digital logic component used in processing arrays for flexible control and data processing in industrial systems.

Component Specifications

Definition
A Configurable Logic Block (CLB) is a fundamental building block in Field-Programmable Gate Arrays (FPGAs) and other programmable logic devices, consisting of Look-Up Tables (LUTs), flip-flops, and multiplexers that can be configured to implement custom digital logic functions, enabling real-time processing, signal routing, and control operations in industrial automation and electronic systems.
Working Principle
Operates by storing configuration data in SRAM cells that define the behavior of LUTs and interconnect switches; LUTs implement combinational logic functions by mapping input combinations to output values, while flip-flops provide sequential logic capabilities for timing and state management, allowing dynamic reconfiguration to adapt to different processing tasks.
Materials
Semiconductor materials (silicon substrate), copper interconnects, dielectric layers, with packaging in ceramic or plastic (e.g., BGA, QFP).
Technical Parameters
  • LUT Size 4-6 inputs typical
  • Power Consumption 0.1-1 W per block
  • Flip-Flops per CLB 1-2
  • Process Technology 7-28 nm nodes
  • Operating Frequency Up to 500 MHz
  • Configuration Memory SRAM-based
Standards
ISO 26262, IEC 61508, IEEE 1149.1
