Functional Description
The CY7C343B is a high-performance, high-density erasable
programmable logic device, available in 44-pin PLCC and
HLCC packages.
The CY7C343B contains 64 highly flexible macrocells and 128
expander product terms. These resources are divided into four
Logic Array Blocks (LABs) connected through the Programma-
ble Inter-connect Array (PIA). There are 8 input pins, one that
doubles as a clock pin when needed. The CY7C343B also has
28 I/O pins, each connected to a macrocell (6 for LABs A and
C, and 8 for LABs B and D). The remaining 36 macrocells are
used for embedded logic.
The CY7C343B is excellent for a wide range of both synchro-
nous and asynchronous applications.
