Functional Description[1]

The CY7C1339G SRAM integrates 128K x 32 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:D], and BWE), and Global Write (GW). Asynchronous inputs include the Output Enable (OE) and the ZZ pin.
