ATF2500C-20PU - Complex Programmable Logic Device

ATF2500C-20PU  - Complex Programmable Logic Device

Before, PLDs were invented, read-only memory (ROM) chips were used to create arbitrary combinational logic functions of a number of inputs.
A programmable logic device or PLD is an electronic component used to build reconfigurable digital circuits. Unlike a logic gate, which has a fixed function, a PLD has an undefined function at the time of manufacture. Before the PLD can be used in a circuit it must be programmed, that is, reconfigured.
