CPLDs

CPLDs stand for complex programmable logic devices. They are used to implement complex combinational or sequential circuits. They 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.

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

  • 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.

How do FPGA 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.

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 portables devices such as phones tablets and smaller address decoding designs applications.
