CY37256VP160-100AC

5V ， 3.3V ， ISRTM高性能的CPLD 5V, 3.3V, ISRTM High-Performance CPLDs

General Description

The Ultra37000™ family of CMOSCPLDs provides a range of high-density programmable logic solutions with unparalleled system performance. The Ultra37000 family is designed to bring the flexibility, ease of use, and performance of the 22V10 to high-density CPLDs. The architecture is based on a number of logic blocks that are connected by a Programmable Interconnect Matrix PIM.
