Functional Description
The CY7C343 is a high-performance, high-density erasable
programmable logic device, available in 44-pin PLCC and
HLCC packages.
The CY7C343 contains 64 highly flexible macrocells and 128
expander product terms. These resources are divided into four
Logic Array Blocks (LABs) connected through the Program-
mable Inter-connect Array (PIA). There are eight input pins,
one that doubles as a clock pin when needed. The CY7C343
also has 28 I/O pins, each connected to a macrocell (six for
LABs A and C, and eight for LABs B and D). The remaining 36
macrocells are used for embedded logic.
The CY7C343 is excellent for a wide range of both
synchronous and asynchronous applications.
