CPLD stands for complex programmable logic devices. They are used to implement complex combinational or sequential circuits and are made up of logic array blocks, programmable interconnects, and I/O blocks. RS Components offer a range of high-quality semiconductor devices from leading brands including Microchip, Xilinx, Lattice Semiconductor and Altera.

What is in a CPLD?

  • Logic Array Blocks - Logic array blocks consist of macrocells, inward / non-inward metrics, and support for flip flops ICs that allow you to implement sequential circuits.
  • Programmable Interconnects - Programmable interconnects are used to disperse signals for one logic array block to another.
  • I/O Blocks - I/O blocks are pins that can be programmed as an input pin, output pin or both.

Features and Benefits of CPLDs

  • Non-volatile configuration memory.
  • CPLD can function immediately on start-up as there is no ROM required.
  • A large number of gates available, typically thousands to tens of thousands.
  • On-chip non-volatile memory.
  • Low-power requirements.
  • Easy to use.

Where would you find a CPLD?

  • High performance, critical applications.
  • Digital designs to perform the function of a boot loader.
  • Loading configuration data of a field-programmable gate array from non-volatile memory.
  • Small design applications like dress decoding.
  • Cost-sensitive, battery-operated portable devices.

Applications of CPLD

CPLDs are ideal for high performance, control applications and digital designs to perform boot loader functions. We offer cost-effective CPLDs for portable devices such as phones, tablets, and smaller address decoding designs applications.

How do FPGAs differ from CPLDs?

FPGA stands for Field Programmable Gate Array. FPGAs are small semiconductor devices known as integrated circuits or ICs for short. FPGAs are built from one basic logic cell, duplicated hundreds of time. FPGAs are found in radar systems, military hardware, medical devices and telecommunications.
