Functional Description

The CY7C1360C/CY7C1362C SRAM integrates 262,144 x 36 and 524,288 x 18 SRAM cells with advanced synchronous peripheral circuitry and a two-bit counter for internal burst operation. All synchronous inputs are gated by registers controlled by a positive-edge-triggered Clock Input (CLK). The synchronous inputs include all addresses, all data inputs, address-pipelining Chip Enable (CE1), depth-expansion Chip Enables (CE2and CE3), Burst Control inputs (ADSC, ADSP, andADV), Write Enables (BWX, and BWE), and Global Write (GW). Asynchronous inputs include the Output Enable (OE) and the ZZ pin.
