Functional Description
The CY7C09079V/89V/99V and CY7C09179V/89V/99V are
high speed synchronous CMOS 32K, 64K, and 128K x 8/9
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
used to bypass the pipelined output register to eliminate access
latency. In flow-through mode, data is available tCD1 = 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 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 enable the shortest possible cycle times.
A HIGH on CE0 or LOW on CE1 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 CE0 LOW and CE1 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.
Pin Configurations

Notes
4. When writing simultaneously to the same location, the final value cannot be guaranteed.
5. This pin is NC for CY7C09079V.
6. This pin is NC for CY7C09079V and CY7C09089V.
7. For CY7C09079V and CY7C09089V, pin #23 connected to VCC is pin compatible with an IDT 5V x8 pipelined device; connecting pin #23 and #53 to GND is pin
compatible with an IDT 5V x16 flow-through device.
