cy7c09089v/99v cy7c09179v/99v document #: 38-06043 rev. *f page 3 of 28 functional description the cy7c09089v/99v and cy7c09179v/99v are high speed synchronous cmos 64 k/128 k 8 and 32 k/128 k 9 dual-port static rams. two ports are provided, permitting independent, simultaneous access for reads and writes to any location in memory. [4] registers on control, address, and data lines enable minimal setup and hold times. in pipelined output mode, data is registered for decreased cycle time. clock to data valid t cd2 =6.5 ns [5] (pipelined). flow-through mode can also be used to bypass the pipelined output register to eliminate access latency. in flow-through mode, data is available t cd1 = 18 ns after the address is clocked into the device. pipelined output or flow-through mode is selected via the ft /pipe pin. each port contains a burst count er 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 enable th e shortest possible cycle times. a high on ce 0 or low on ce 1 for one clock cycle powers down the internal circuitry to reduce the static power consumption. the use of multiple chip enables enables easier banking of multiple chips for depth expansion configurations. in the pipelined mode, one cycle is required with ce 0 low and ce 1 high to reactivate the outputs. counter enable inputs are provided to stall the operation of the address input and use the internal address generated by the internal counter for fast interleaved memory applications. a port?s burst counter is loaded with the port?s address strobe (ads ). when the port?s count enable (cnten ) is asserted, the address counter increments on each low-to-high transition of that port?s clock signal. this reads/writes one word from/into each successive address location until cnten is deasserted. the counter can address the entire memory array and loops back to the start. counter reset (cntrst ) is used to reset the burst counter. all parts are available in 100-pin thin quad plastic flatpack (tqfp) packages. notes 4. when writing simultaneously to the same location, the final value cannot be guaranteed. 5. see page 9 and page 10 for load conditions.
