Features
Functional Description
■ True dual-ported memory cells which allow simultaneous
access of the same memory location
The CY7C09569V and CY7C09579V are high-speed 3.3 V
synchronous CMOS 16 K and 32 K × 36 dual-port static RAMs.
Two ports are provided, permitting independent, simultaneous
access for reads and writes to any location in memory.
Registers on control, address, and data lines allow for minimal
set-up and hold times. In pipelined output mode, data is regis-
tered for decreased cycle time. Clock to data valid tCD2 = 5 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 = 12.5 ns after
the address is clocked into the device. Pipelined output or
flow-through mode is selected via the FT/Pipe pin.
■ Two flow-through/pipelined devices
❐ 16 K × 36 organization (CY7C09569V)
❐ 32 K × 36 organization (CY7C09579V)
■ 0.25-micron CMOS for optimum speed/power
■ Three modes
❐ Flow-through
❐ Pipelined
❐ Burst
Each port contains a burst counter on the input address
register. The internal write pulse width is independent of the
external R/W LOW duration. The internal write pulse is
self-timed to allow the shortest possible cycle times.
■ Bus-matching capabilities on right port
(×36 to ×18 or ×9)
■ Byte-select capabilities on left port
■ 100-MHz pipelined operation
A HIGH on CE for one clock cycle will power down the internal
circuitry to reduce the static power consumption. In the
pipelined mode, one cycle is required with CE LOW to
reactivate the outputs.
■ High-speed clock to data access 5/6 ns
■ 3.3 V low operating power
❐ Active = 250 mA (typical)
❐ Standby = 10 μA (typical)
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.
■ Fully synchronous interface for ease of use
■ Burst counters increment addresses internally
❐ Shorten cycle times
❐ Minimize bus noise
❐ Supported in flow-through and pipelined modes
■ Counter address read back via I/O lines
■ Single chip enable
Parts are available in 144-pin Thin Quad Plastic Flatpack
(TQFP), 144-pin Pb-free Thin Quad Plastic Flatpack (TQFP)
and 172-ball Ball Grid Array (BGA) packages.
■ Automatic power-down
■ Commercial and industrial temperature ranges
■ Compact package

Counter Operation
Bus Match Operation
The CY7C09569V/09579V Dual-Port RAM (DPRAM) contains
on-chip address counters (one for each port) for the
synchronous members of the product family. Besides the main
x36 format, the right port allows bus matching (x18 or x9,
user-selectable). An internal sub-counter provides the extra
addresses required to sequence out the 36-bit word in 18-bit
or 9-bit increments. The sub-counter counts up in the “Little
Endian” mode, and counts down if the user has chosen the
“Big Endian” mode. The address counter is required to be in
increment mode in order for the sub-counter to sequence out
the second word (in x18 mode) or the remaining three bytes
(in x9 mode).
The right port of the CY7C09569V/09579V 16K/32Kx36
dual-port SRAM can be configured in a 36-bit long-word, 18-bit
word, or 9-bit byte format for data I/O. The data lines are
divided into four lanes, each consisting of 9 bits (byte-size data
lines).

For a x36 format (the only active format on the left port), each
address counter in the CY7C09579V uses addresses (A0–14).

For the right port (allowing for the bus-matching feature), a
maximum of two address bits (out of a 2-bit sub-counter) are
added.
BM SIZE
1. ADSL/R (pin #23/86) is a port’s address strobe, allowing the
loading of that port's burst counters if the corresponding
CNTENL/R pin is active as well.
The Bus Match Select (BM) pin works with Bus Size Select
(SIZE) and Big Endian Select (BE) to select the bus width
(long-word, word, or byte) and data sequencing arrangement
for the right port of the dual-port device. A logic “0” applied to
both the Bus Match Select (BM) pin and to the Bus Size Select
(SIZE) pin will select long-word (36-bit) operation. A logic “1”
level applied to the Bus Match Select (BM) pin will enable
whether byte or word bus width operation on the right port I/Os
depending on the logic level applied to the SIZE pin. The level
of Bus Match Select (BM) must be static throughout normal
device operation.
2. CNTENL/R (pin #25/84) is a port’s count enable, provided
to stall the operation of the address input and utilize the
internal address generated by the internal counter for fast
interleaved memory applications; when asserted, the
address counter will increment on each positive transition
of that port's clock signal.
3. CNTRSTL/R (pin #24/85) is a port's burst counter reset.
A new read-back (Hold+Read Mode) feature has been added,
which is different between the left and right port due to the bus
matching feature provided only for the right port. In read-back
mode the internal address of the counter will be read from the
data I/Os as shown in Figure 1.
The Bus Size Select (SIZE) pin selects either a byte or word
data arrangement on the right port when the Bus Match Select
(BM) pin is HIGH. A logic “1” on the SIZE pin when the BM pin
is HIGH selects a byte bus (9-bit) data arrangement. A logic
“0” on the SIZE pin when the BM pin is HIGH selects a word
bus (18-bit) data arrangement. The level of the Bus Size Select
(SIZE) must also be static throughout normal device operation.
Figure 1. Counter Operation Diagram
The Big Endian Select (BE) pin is a multiple-function pin during
word or byte bus selection (BM = 1). BE is used in Big Endian
Select mode to determine the order by which bytes (or words)
of data are transferred through the right data port. A logic “0”
on the BE pin will select Little Endian data sequencing
arrangement and a logic “1” on the BE pin will select a Big
Endian data sequencing arrangement. Under these circum-
stances, the level on the BE pin should be static throughout
dual-port operation.

Long-Word (36-bit) Operation
ADS
______________
Bus Match Select (BM) and Bus Size Select (SIZE) set to a
logic “0” will enable standard cycle long-word (36-bit)
operation. In this mode, the right port’s I/O operates essentially
in an identical fashion to the left port of the dual-port SRAM.
However no Byte Select control is available. All 36 bits of the
long-word are shifted into and out of the right port’s I/O buffer
stages. All read and write timing parameters may be identical
with respect to the two data ports. When the right port is
configured for a long-word size, Big- Endian Select (BE) pin
has no application and their inputs are “Don’t Care”[82] for the
external user.

Note
82. Even though a logic level applied to a “Don’t Care” input will not change the logical operation of the dual-port, inputs that are temporarily a “Don’t Care” (along
with unused inputs) must not be allowed to float. They must be forced either HIGH or LOW.

Word (18-bit) Operation
Byte (9-bit) Operation
Word (18-bit) bus sizing operation is enabled when Bus Match
Select (BM) is set to a logic “1” and the Bus Size Select (SIZE)
pin is set to a logic “0.” In this mode, 18 bits of data are ported
through I/O0R–17R. The level applied to the Big Endian (BE) pin
determines the right port data I/O sequencing order (Big Endian
or Little Endian).
Byte (9-bit) bus sizing operation is enabled when Bus Match
Select (BM) is set to a logic “1” and the Bus Size Select (SIZE)
pin is set to a logic “1.” In this mode, 9 bits of data are ported
through I/O0R–8R
.
Big Endian and Little Endian data sequencing is available for
dual-port operation. The level applied to the Big Endian pin (BE)
under these circumstances will determine the right port data I/O
sequencing order (Big or Little Endian). A logic LOW applied to
the BE pin during byte (9-bit) bus size operation will select Little
Endian operation. In this case, the least significant data byte is
read from the right port first or written to the right port first. A logic
“1” on the BE pin during byte (9-bit) bus size operation will select
Big Endian operation resulting in the most significant data word
to be transferred through the right port first. Internally, the data
will be stored in the appropriate 36-bit LSB or MSB I/O memory
location. Device operation requires a minimum of four clock
cycles to read or write during byte (9-bit) bus size operation. An
internal sub-counter automatically increments the right port
multiplexer control when Little or Big Endian operation is in
effect. When transferring data in byte (9-bit) bus match format,
the unused I/O pins (I/O9RQ–35R) are three-stated.
During word (18-bit) bus size operation, a logic LOW applied to
the BE pin will select Little Endian operation. In this case, the
least significant data word is read from the right port first or
written to the right port first. A logic “1” on the BE pin during word
(18-bit) bus size operation will select Big Endian operation
resulting in the most significant data word being transferred
through the right port first. Internally, the data will be stored in the
appropriate 36-bit LSB or MSB I/O memory location. Device
operation requires a minimum of two clock cycles to read or write
during word (18-bit) bus size operation. An internal sub-counter
automatically increments the right port multiplexer control when
Little or Big Endian operation is in effect.
