CY7C343B-35HHI

43B CY7C343B 64-Macrocell MAX® EPLD Features • • • • 64 MAX macrocells in 4 LABs 8 dedicated inputs, 24 bidirectional I/O pins Programmable interconnect array Advanced 0.65-micron CMOS technology to increase performance • Available in 44-pin HLCC, PLCC • Lowest power MAX device 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 Programmable 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 synchronous and asynchronous applications. Functional Description The CY7C343B is a high-performance, high-density erasable programmable logic device, available in 44-pin PLCC and HLCC packages.
