기능 설명
The CY7C1328G 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 (CE1), depth-expansion chip enables (CE2 and CE3), burst control inputs (ADSC, ADSP, and ADV), write enables (BW[A:B], and BWE), and global write (GW). Asynchronous inputs include the output enable (OE) and the ZZ pin.
