CY7C1327G-166AXC

The CY7C1327G SRAM integrates 256 K × 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 , depth-expansion chip enables, burst control inputs (ADSC, ADSP, and ADV), write enables, and global write (GW). Asynchronous inputs include the output enable (OE) and the ZZ pin.
