CY7C1354C CY7C1356C Document #: 38-05538 Rev . *G Page 7 of 28 Functional Overview The CY7C1354C and C Y7C1356C are synchronous-pipeli ned Burst NoBL SRAMs designed specifically to eliminate wait states during Write/Read transi tions. All synchronous input s pass through input registers co ntrolled by the rising ed ge of the clock.
