Programmable Array Logic Circuits

Programmable Array Logic Circuits (PALCs) are crucial semiconductors typically used in programmable logic devices (PLDs). They comprise a programmable AND array and a fixed OR array. PALs only have a programmable AND array, which makes them easy to use. However, they are not flexible compared to PLDs, as they are limited to the number of AND gates.

What is a Programmable Logic Array Used for?

A programmable logic array is a programmable logic component that enables the execution of combinational logic circuits having a fixed OR array and a programmable AND array. This structural approach allows the design of the particular logic function by configuring the links in the AND array while the OR array remains static. PALs are basically used in many digital systems to make custom logic circuits effectively, as they comprise a minute programmable read-only memory PROM and an extra output logic employed to establish a required logic function with fewer components. 

Core Components of Programmable Logic Arrays

Programmable Logic Arrays involve several vital components, such as:

• Programmable AND Array: Consists of multiple AND gates programmed by the designer.
• Fixed OR Array: A set of fixed OR gates to combine the outputs with programmable AND gates.
• Inputs and Outputs: Have a variety of inputs feeding into the AND array and several well-defined outputs that represent the results of logical operations.
• Programming Mechanism: PALs can be programmed using Hardware description language HDL or via specific programming tools, defining how the inputs are linked to the AND gates.
