What is programmable logic device?

1 Answer

Answer :

Programmable Logic Devices (PLD)


•PLD chips can be erased electrically and program to implement different logic function.

•Designing with PLD chips is faster which reduce time to bring the product in market.

•To reprogram PLD we do not have to redesign circuit board.

•Simple Programmable Logic Devices (SPLD), Complex Programmable Logic Devices (CPLD) and Field Programmable Gate Array (FPGA) are the types of Programmable Logic Devices (PLD).

•SPLD includes Read Only Memory (ROM), Programmable Logic Array (PLA), Programmable Array Logic (PAL) and Generic Array Logic (GAL).

•FPGA and CLPD are the types of advanced PLDs.
