CY7C09353AV

The CY7C09349AV and CY7C09359AV are high-speed 3.3V synchronous CMOS 4K and 8K x 18 dual-port static RAMs. Two ports of CY7C09353AV are provided, permitting independent, simultaneous access for reads and writes to any location in memor2[2] Registers on control, address, and data lines allow for minimal setup and hold times. In pipelined output mode, data is registered for decreased cycle time. Clock to data valid tCD2 = 9 ns (pipelined). Flow-through mode of CY7C09353AV can also be used to bypass the pipelined output register to eliminate access latency. In flowthrough mode data will be available tCD1 = 18 ns after the address is clocked into the device. Pipelined output or flowthrough mode of CY7C09353AV is selected via the FT/Pipe pin.

Each port of CY7C09353AV  contains a burst counter on the input address register. The internal write pulse width is independent of the LOWto- HIGH transition of the clock signal. The internal write pulse is self-timed to allow the shortest possible cycle times.
