CY7C09159AV
Functional Description
The CY7C09159AV is a high-speed synchronous CMOS 8 K × 9
dual-port static RAM. Two ports are provided, permitting
independent, simultaneous access for reads and writes to any
location in memory.[1] Registers on control, address, and data
lines allow for minimal setup and hold times. In pipelined output
mode, data is registered for decreased cycle time. Clock to data
valid tCD2 = 9 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 = 20 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 allow the shortest possible cycle times.
A HIGH on CE0 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 CE0 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 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.
All parts are available in 100-pin thin quad plastic flatpack
(TQFP) packages.
Note
1. When simultaneously writing to the same location, final value cannot be guaranteed.

Notes
4. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
5. ADS = VIL, CNTEN and CNTRST = VIH
6. The output is disabled (high-impedance state) by CE0=VIH or CE1 = VIL following the next rising edge of the clock.
7. 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.

8. 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 data sheet. ADDRESS(B1)
= ADDRESS(B2).
9. OE and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH.
10. The same waveforms apply for a right port write to flow-through left port read.
11. CE0 and ADS = VIL; CE1, CNTEN, and CNTRST = VIH.
12. OE = VIL for the right port, which is being read from. OE = VIH for the left port, which is being written to.
13. 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.

Notes
26. 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
27. Output state (HIGH, LOW, or High-Impedance) is determined by the previous cycle control signals.
28. CE0 = VIL; CE1 = VIH.
29. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset.

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