Answer :

Complex Programmable Logic Devices

(CPLD)

•CPLDs are the collection of SPLD structures which are interconnected via multiplexer or switch matrix.

•CPLD consists of number of logic blocks or functional blocks.

•And each block contain PLA or PAL.

•Using CPLDs more complex design can be implemented.

•Propagation delay is about 8 ns.

•CPLD have large number of gates and can include complicated feedback path.

•CPLD are ideal for critical control application because it offers predictable timing characteristics.

•CPLD are use in cost sensitive application and it have low power usage.
