CY7C09389V-7AC

Product Summary

The CY7C09389V-7AC is a 3.3V 16K/32K/64K x 16/18 Synchronous Dual-Port Static RAM. Two ports are provided; permitting independent, simultaneous access for reads and writes to any location in memory. Registers on control, address, and data lines allow for minimal set-up and hold times. In pipelined output mode, data is registered for decreased cycle time. Clock to data valid tCD2 = 6.5 ns (pipelined). Flow-through mode can also be used to bypass the pipelined output register to eliminate access latency. In flow-through mode data will be available tCD1 = 18 ns after the address is clocked into the CY7C09389V-7AC. Pipelined output or flow-through mode is selected via the FT/Pipe pin. Each port of the CY7C09389V-7AC contains a burst counter on the input address register. The internal write pulse width is independent of the LOW to HIGH transition of the clock signal. The internal write pulse is self-timed to allow the shortest possible cycle times.
