Cyclone III Device Family Architecture
Cyclone III device family includes a customer-defined feature set that is optimized for
portable applications and offers a wide range of density, memory, embedded
multiplier, and I/O options. Cyclone III device family supports numerous external
memory interfaces and I/O protocols that are common in high-volume applications.
The Quartus II software features and parameterizable IP cores make it easier for you
to use the Cyclone III device family interfaces and protocols.
The following sections provide an overview of the Cyclone III device family features.
Logic Elements and Logic Array Blocks
The logic array block (LAB) consists of 16 logic elements and a LAB-wide control
block. An LE is the smallest unit of logic in the Cyclone III device family architecture.
Each LE has four inputs, a four-input look-up table (LUT), a register, and output logic.
The four-input LUT is a function generator that can implement any function with four
variables.

For more information about LEs and LABs, refer to the Logic Elements and Logic Array
Blocks in the Cyclone III Device Family chapter.
