CY7C1460AV33 CY7C1462AV33 CY7C1464AV33 Functional Overview the internal burst counter regardless of the state of chip enables inputs or WE. WE is latched at the beginning of a burst The CY7C1460AV33/CY7C1462AV33/CY7C1464AV33 are cycle. Therefore, the type of access (Read or Write) is synchronous-pipelined Burst NoBL SRAMs designed specifi- maintained throughout the burst sequence. cally to eliminate wait states during Write/Read transitions. All synchronous inputs pass through input registers
