CY7C09169 General Description

The CY7C09159 and CY7C09169 are high speed synchronous CMOS 8K and 16K x 9 dual-port static RAMs. Two ports are provided, permitting independent, simultaneous access for reads and writes to any location in memory.^[2] 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 t _CD2 = 6.5 ns (pipe-lined). 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 t_CD1 = 15 ns after the address is clocked into the device. Pipelined output or flow-through mode is selected via the F T /Pipe pin.

Each port 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.

A HIGH on CE ₀ or LOW on CE₁ for one clock cycle will power down the internal circuitry to reduce the static power consumption. The use of multiple Chip Enables allows easier banking of multiple chips for depth expansion configurations. In the pipelined mode, one cycle is required with CE ₀ LOW and CE₁ HIGH to reactivate the outputs. Counter enable inputs are provided to stall the operation of the address input and utilize 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 deasserted. The counter can address the entire memory array and will loop 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.
