Description
A0L–A15L
A0R–A15R
Address Inputs (A0–A14 for 32K, A0–A13 for 16K devices).
ADSL
ADSR
Address Strobe Input. Used as an address qualifier. This signal must be asserted LOW to access
the part using an externally supplied address. Asserting this signal LOW also loads the burst counter
with the address present on the address pins.
CE0L, CE1L
CE0R,CE1R
Chip Enable Input. To select either the left or right port, both CE0 AND CE1 must be asserted to their
active states (CE0 VIL and CE1 VIH).
CLKL
CLKR
Clock Signal. This input can be free running or strobed. Maximum clock input rate is fMAX.
CNTENL
CNTENR
Counter Enable Input. Asserting this signal LOW increments the burst address counter of its
respective port on each rising edge of CLK. CNTEN is disabled if ADS or CNTRST are asserted LOW.
CNTRSTL
CNTRSTR
Counter Reset Input. Asserting this signal LOW resets the burst address counter of its respective
port to zero. CNTRST is not disabled by asserting ADS or CNTEN.
I/O0L–I/O17L
I/O0R–I/O17R Data Bus Input/Output (I/O0–I/O15 for × 16 devices).
LBL
LBR
Lower Byte Select Input. Asserting this signal LOW enables read and write operations to the lower
byte. (I/O0–I/O8 for × 18, I/O0–I/O7 for × 16) of the memory array. For read operations both the LB and
OE signals must be asserted to drive output data on the lower byte of the data pins.
UBL
UBR
Upper Byte Select Input. Same function as LB, but to the upper byte (I/O8/9L–I/O15/17L).
OEL
OER
Output Enable Input. This signal must be asserted LOW to enable the I/O data pins during read
operations.
R/WL
R/WR
Read/Write Enable Input. This signal is asserted LOW to write to the dual port memory array. For
read operations, assert this pin HIGH.
FT/PIPEL
FT/PIPER
Flow Through/Pipelined Select Input. For flow through mode operation, assert this pin LOW. For
pipelined mode operation, assert this pin HIGH.
GND
Ground Input.
NC
No Connect.
VCC
Power Input.

CY7C09369V/89V
Functional Overview
The CY7C09269V/79V/89V and CY7C09369V/89V are high
speed 3.3 V synchronous CMOS 16K, 32K, and 64K × 16 and
16K and 64K × 18 dual-port static RAMs. Two ports are provided,
permitting independent, simultaneous access for reads and
writes to any location in memory [11]. 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 and clock to data valid tCD2 = 7.5 ns [12] (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 tCD1 = 18 ns after the address is clocked into the
device. Pipelined output or flow through mode is selected
through 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 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 or into
each successive address location, until CNTEN is deasserted.
The counter can address the entire memory array and 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.
Notes
11. When writing simultaneously to the same location, the final value cannot be guaranteed.

Notes
21. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
22. ADS = VIL, CNTEN and CNTRST = VIH.
23. The output is disabled (high impedance state) by CE0=VIH or CE1 = VIL following the next rising edge of the clock.
24. 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
25. 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).
26. UB, LB, OE and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH.
27. The same waveforms apply for a right port write to flow through left port read.
28. CE0, UB, LB, and ADS = VIL; CE1, CNTEN, and CNTRST = VIH.
29. OE = VIL for the Right Port, which is being read from. OE = VIH for the Left Port, which is being written to.
30. 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
51. “X” = “Don’t Care”, “H” = VIH, “L” = VIL.
52. ADS, CNTEN, CNTRST = “Don’t Care”.
53. OE is an asynchronous input signal.
54. When CE changes state in the pipelined mode, deselection and read happen in the following clock cycle.
55. ADS = VIL, CNTEN and CNTRST = VIH.
56. CE0 and OE = VIL; CE1 and R/W = VIH.
57. Data shown for flow through mode; pipelined mode output is delayed by one cycle.
58. Counter operation is independent of CE0 and CE1.
