CY7C1360A-150AJC

256K ×36 / 512K ×18同步流水线突发SRAM 256K x 36/512K x 18 Synchronous Pipelined Burst SRAM

Functional Description

The Cypress Synchronous Burst SRAM family employs high-speed, low-power CMOS designs using advanced triple-layer polysilicon, double-layer metal technology. Each memory cell consists of four transistors and two high-valued resistors. The CY7C1360A and CY7C1362A SRAMs integrate 262,144 ×36 and 524,288×18 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 CE, depth-expansion Chip Enables CE2and CE3, burst control inputs ADSC, ADSP, and ADV, Write Enables BWa, BWb, BWc, BWd, and BWE, and global Write GW. However, the CE3chip enable input is only available for the TA package version.
