CY7C09079V/89V/99V
CY7C09179V/89V/99V
A HIGH on CE0 or LOW on CE1 for one clock cycle will power
down the internal circuitry to reduce the static power consump-
tion. 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 CE0 LOW and CE1
HIGH to reactivate the outputs.
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 in-
dependent, simultaneous access for reads and writes to any
location in memory.[4] Registers on control, address, and data
lines allow for minimal set-up and hold times. In pipelined out-
put mode, data is registered for decreased cycle time. Clock
to data valid tCD2 = 6.5 ns[1] (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
device. Pipelined output or flow-through mode is selected via
the FT/Pipe pin.
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 asserted,
the address counter will increment on each LOW-to-HIGH
transition of that port’s clock signal. This will read/write one
word from/into each successive address location until 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.
Each port contains a burst counter on the input address regis-
ter. 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.
All parts are available in 100-pin Thin Quad Plastic Flatpack
(TQFP) packages.

Notes:
16. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
17. ADS = VIL, CNTEN and CNTRST = VIH
18. The output is disabled (high-impedance state) by CE0=VIH or CE1 = VIL following the next rising edge of the clock.
19. Addresses do not have to be accessed sequentially since ADS = VIL constantly loads the address on the rising edge of the CLK. Numbers are for reference only.

Notes:
20. In this depth expansion example, B1 represents Bank #1 and B2 is Bank #2; Each Bank consists of one Cypress dual-port device from this datasheet.
ADDRESS(B1) = ADDRESS(B2)
21. OE and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH
22. The same waveforms apply for a right port write to flow-through left port read.
23. CE0 and ADS = VIL; CE1, CNTEN, and CNTRST = VIH
24. OE = VIL for the right port, which is being read from. OE = VIH for the left port, which is being written to.
.
.
.
25. It tCCS ≤ maximum specified, then data from right port READ is not valid until the maximum specified for tCWDD. If tCCS>maximum specified, then data is not
valid until tCCS + tCD1. tCWDD does not apply in this case.

28. During “No Operation”, data in memory at the selected address may be corrupted and should be re-written to ensure data integrity.

Notes:
34. “X” = “Don’t Care”, “H” = VIH, “L” = VIL.
35. ADS, CNTEN, CNTRST = “Don’t Care.”
36. OE is an asynchronous input signal.
37. When CE changes state in the pipelined mode, deselection and read happen in the following clock cycle.
38. CE0 and OE = VIL; CE1 and R/W = VIH
.
39. Data shown for flow-through mode; pipelined mode output will be delayed by one cycle.
40. Counter operation is independent of CE0 and CE1.
