... Control of a semaphore indicates that a shared resource is in use. An automatic power-down feature is controlled independently on each port by a chip select (CE) pin. The CY7C024/0241 and CY7C025/0251 are available in 84-pin PLCCs (CY7C024 and CY7C025 only) and 100-pin Thin Quad Plastic Flatpack (TQFP). • 3901 North First Street • ...

... Two semaphore (SEM) control pins are used for allocating shared resources. With the M/S pin, the CY7C024/0241 and CY7C025/0251 can function as a master (BUSY pins are outputs slave (BUSY pins are inputs). The CY7C024/0241 and CY7C025/0251 have an automatic power-down feature controlled by CE ...
