Functional Description
The FLEx36™ family includes 2-Mbit pipelined, synchronous,
true dual-port static RAMs that are high speed, low power 3.3 V
CMOS. Two ports are provided, permitting independent,
simultaneous access to any location in memory. A particular port
can write to a certain location while another port is reading that
location. The result of writing to the same location by more than
one port at the same time is undefined. Registers on control,
address, and data lines allow for minimal setup and hold time.
During a Read operation, data is registered for decreased cycle
time. Each port contains a burst counter on the input address
register. After externally loading the counter with the initial
address, the counter increments the address internally (more
details to follow). The internal Write pulse width is independent
of the duration of the R/W input 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. One
cycle with chip enables asserted is required to reactivate the
outputs.
Additional features include: readback of burst-counter internal
address value on address lines, counter-mask registers to
control the counter wrap-around, counter interrupt (CNTINT)
flags, readback of mask register value on address lines,
retransmit functionality, interrupt flags for message passing,
JTAG for boundary scan, and asynchronous Master Reset
(MRST).

Master Reset
The FLEx36 family devices undergo a complete reset by taking
its MRST input LOW. The MRST input can switch asynchro-
nously to the clocks. An MRST initializes the internal burst
counters to zero, and the counter mask registers to all ones
(completely unmasked). MRST also forces the Mailbox Interrupt
(INT) flags and the Counter Interrupt (CNTINT) flags HIGH.
MRST must be performed on the FLEx36 family devices after
power up.
Mailbox Interrupts
The upper two memory locations may be used for message
passing and permit communications between ports. Ta b l e 2
shows the interrupt operation for both ports of
CYD02S36V/36VA. The highest memory location, FFFF is the
mailbox for the right port and FFFE is the mailbox for the left port.
Table 2 shows that to set the INTR flag, a Write operation by the
left port to address FFFF asserts INTR LOW. At least one byte
must be active for a Write to generate an interrupt. A valid Read
of the FFFF location by the right port resets INTR HIGH. At least
one byte must be active in order for a Read to reset the interrupt.
When one port Writes to the other port’s mailbox, the INT of the
port that the mailbox belongs to is asserted LOW. The INT is
reset when the owner (port) of the mailbox Reads the contents
of the mailbox. The interrupt flag is set in a flow-thru mode (i.e.,
it follows the clock edge of the writing port). Also, the flag is reset
in a flow-thru mode (i.e., it follows the clock edge of the reading
port).
Each port can read the other port’s mailbox without resetting the
interrupt. And each port can write to its own mailbox without
setting the interrupt. If an application does not require message
passing, INT pins must be left open.
Address Counter and Mask Register
Operations
Each port of these devices has a programmable burst address
counter. The burst counter contains three registers: a counter
register, a mask register, and a mirror register.
The counter register contains the address used to access the
RAM array. It is changed only by the Counter Load, Increment,
Counter Reset, and by master reset (MRST) operations.
The mask register value affects the Increment and Counter
Reset operations by preventing the corresponding bits of the
counter register from changing. It also affects the counter
interrupt output (CNTINT). The mask register is changed only by
the Mask Load and Mask Reset operations, and by the MRST.
The mask register defines the counting range of the counter
register. It divides the counter register into two regions: zero or
more “0s” in the most significant bits define the masked region,
one or more “1s” in the least significant bits define the unmasked
region. Bit 0 may also be “0,” masking the least significant
counter bit and causing the counter to increment by two instead
of one.
The mirror register is used to reload the counter register on
increment operations (see “retransmit,” below). It always
contains the value last loaded into the counter register, and is
changed only by the Counter Load, and Counter Reset opera-
tions, and by the MRST.
Table 3 on page 7 summarizes the operation of these registers
and the required input control signals. The MRST control signal
is asynchronous. All the other control signals in Ta b l e 3 on page
7 (CNT/MSK, CNTRST, ADS, CNTEN) are synchronized to the
port’s CLK. All these counter and mask operations are
independent of the port’s chip enable inputs (CE0 and CE1).
Notes
9. This family of Dual-Ports does not use VCORE, and these pins are internally NC. The next generation Dual-Port family, the FLEx36-E™, uses VCORE of 1.5 V or 1.8V.
Please contact local Cypress FAE for more information.
10. CE is internal signal. CE = LOW if CE0 = LOW and CE1 = HIGH. For a single Read operation, CE only needs to be asserted once at the rising edge of the CLK and
can be deasserted after that. Data is out after the following CLK edge and is three-stated after the next CLK edge.
11. OE is “Don’t Care” for mailbox operation.
12. At least one of BE0, BE1, BE2, or BE3 must be LOW.
13. “X” = “Don’t Care,” “H” = HIGH, “L” = LOW.

Counter enable (CNTEN) 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 when the port’s
address strobe (ADS) and CNTEN signals are LOW. When the
port’s CNTEN is asserted and the ADS is deasserted, the
address counter increments on each LOW to HIGH transition of
that port’s clock signal. This Read’s or Write’s 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
unmasked portion of the burst counter to 0s. A counter-mask
register is used to control the counter wrap.
Counter Reset Operation
All unmasked bits of the counter and mirror registers are reset to
“0.” All masked bits remain unchanged. A Mask Reset followed
by a Counter Reset resets the counter and mirror registers to
0000, as does master reset (MRST).
Counter Load Operation
The address counter and mirror registers are both loaded with
the address value presented at the address lines.

Counter Increment Operation
Once the address counter register is initially loaded with an
external address, the counter can internally increment the
address value, potentially addressing the entire memory array.
Only the unmasked bits of the counter register are incremented.
The corresponding bit in the mask register must be a “1” for a
counter bit to change. The counter register is incremented by 1
if the least significant bit is unmasked, and by 2 if it is masked. If
all unmasked bits are “1,” the next increment wraps the counter
back to the initially loaded value. If an Increment results in all the
unmasked bits of the counter being “1s,” a counter interrupt flag
(CNTINT) is asserted. The next Increment returns the counter
register to its initial value, which was stored in the mirror register.
The counter address can instead be forced to loop to 0000 by
externally connecting CNTINT to CNTRST.[16] An increment that
results in one or more of the unmasked bits of the counter being
“0” de-asserts the counter interrupt flag. The example in
Figure 3 on page 10 shows the counter mask register loaded with
a mask value of 003Fh unmasking the first 6 bits with bit “0” as
the LSB and bit “16” as the MSB. The maximum value the mask
register can be loaded with is FFFFh. Setting the mask register
to this value allows the counter to access the entire memory
space. The address counter is then loaded with an initial value
of 8h. The base address bits (in this case, the 6th address
through the 16th address) are loaded with an address value but
do not increment once the counter is configured for increment
operation. The counter address starts at address 8h. The
counter increments its internal address value till it reaches the
mask register value of 3Fh. The counter wraps around the
memory block to location 8h at the next count. CNTINT is issued
when the counter reaches its maximum value.
Counter Hold Operation
The value of all three registers can be constantly maintained
unchanged for an unlimited number of clock cycles. Such
operation is useful in applications where wait states are needed,
or when address is available a few cycles ahead of data in a
shared bus interface.
Counter Interrupt
The counter interrupt (CNTINT) is asserted LOW when an
increment operation results in the unmasked portion of the
counter register being all “1s.” It is deasserted HIGH when an
Increment operation results in any other value. It is also
de-asserted by Counter Reset, Counter Load, Mask Reset and
Mask Load operations, and by MRST.
Counter Readback Operation
The internal value of the counter register can be read out on the
address lines. Readback is pipelined; the address is valid tCA2
after the next rising edge of the port’s clock. If address readback
occurs while the port is enabled (CE0 LOW and CE1 HIGH), the
data lines (DQs) are three-stated. Figure 2 on page 9 shows a
block diagram of the operation.
Retransmit
Retransmit is a feature that allows the Read of a block of memory
more than once without the need to reload the initial address.
This eliminates the need for external logic to store and route
data. It also reduces the complexity of the system design and
saves board space. An internal “mirror register” is used to store
the initially loaded address counter value. When the counter
unmasked portion reaches its maximum value set by the mask
register, it wraps back to the initial value stored in this “mirror
register.” If the counter is continuously configured in increment
mode, it increments again to its maximum value and wraps back
to the value initially stored into the “mirror register.” Thus, the
repeated access of the same data is allowed without the need
for any external logic.
Mask Reset Operation
The mask register is reset to all “1s,” which unmasks every bit of
the counter. Master reset (MRST) also resets the mask register
to all “1s.”
Mask Load Operation
The mask register is loaded with the address value presented at
the address lines. Not all values permit correct increment opera-
tions. Permitted values are of the form 2n – 1 or 2n – 2. From the
most significant bit to the least significant bit, permitted values
have zero or more “0s,” one or more “1s,” or one “0.” Thus FFFF,
03FE, and 0001 are permitted values, but F0FF, 03FC, and 0000
are not.
Mask Readback Operation
The internal value of the mask register can be read out on the
address lines. Readback is pipelined; the address is valid tCM2
after the next rising edge of the port’s clock. If mask readback
occurs while the port is enabled (CE0 LOW and CE1 HIGH), the
data lines (DQs) are three-stated. Figure 2 on page 9 shows a
block diagram of the operation.
Counting by Two
When the least significant bit of the mask register is “0,” the
counter increments by two. This may be used to connect the x36
devices as a 72-bit single port SRAM in which the counter of one
port counts even addresses and the counter of the other port
counts odd addresses. This even-odd address scheme stores
one half of the 72-bit data in even memory locations, and the
other half in odd memory locations.
Note
16. CNTINT and CNTRST specs are guaranteed by design to operate properly at speed grade operating frequency when tied together.

IEEE 1149.1 Serial Boundary Scan (JTAG)[18]
The FLEx36 family devices incorporate an IEEE 1149.1 serial
boundary scan test access port (TAP). The TAP controller
functions in a manner that does not conflict with the operation of
other devices using 1149.1-compliant TAPs. The TAP operates
using JEDEC-standard 3.3V IO logic levels. It is composed of
three input connections and one output connection required by
the test logic defined by the standard.
Performing a TAP Reset
A reset is performed by forcing TMS HIGH (VDD) for five rising
edges of TCK. This reset does not affect the operation of the
devices, and may be performed while the device is operating. An
MRST must be performed on the devices after power up.
Performing a Pause/Restart
When a SHIFT-DR PAUSE-DR SHIFT-DR is performed the scan
chain outputs the next bit in the chain twice. For example, if the
value expected from the chain is 1010101, the device outputs a

erroneous failure for the devices in a scan test. Therefore the

Figure 6. Read Cycle[27, 28, 29, 30, 31]
Notes
27. CE is internal signal. CE = LOW if CE0 = LOW and CE1 = HIGH. For a single Read operation, CE only needs to be asserted once at the rising edge of the CLK andcan
be deasserted after that. Data is out after the following CLK edge and is three-stated after the next CLK edge.
28. OE is asynchronously controlled; all other inputs (excluding MRST and JTAG) are synchronous to the rising clock edge.
29. ADS = CNTEN = LOW, and MRST = CNTRST = CNT/MSK = HIGH.
30. The output is disabled (high-impedance state) by CE = VIH following the next rising edge of the clock.
31. Addresses do not have to be accessed sequentially since ADS = CNTEN = VIL with CNT/MSK = VIH constantly loads the address on the rising edge of the CLK.
Numbers are for reference only.

Notes
32. In this depth-expansion example, B1 represents Bank #1 and B2 is Bank #2; each bank consists of one Cypress FLEx36 device from this data sheet. ADDRESS(B1)

33. ADS = CNTEN= BE0 – BE3 = OE = LOW; MRST = CNTRST = CNT/MSK = HIGH.
34. Addresses do not have to be accessed sequentially since ADS = CNTEN = VIL with CNT/MSK = VIH constantly loads the address on the rising edge of the CLK.
Numbers are for reference only.
35. Output state (HIGH, LOW, or high-impedance) is determined by the previous cycle control signals.
36. During “No Operation,” data in memory at the selected address may be corrupted and must be rewritten to ensure data integrity.
37. CE0 = OE = BE0 – BE3 = LOW; CE1 = R/W = CNTRST = MRST = HIGH.
38. CE0 = BE0 – BE3 = R/W = LOW; CE1 = CNTRST = MRST = CNT/MSK = HIGH. When R/W first switches low, since OE = LOW, the Write operation cannot be completed
(labelled as no operation). One clock cycle is required to three-state the IO for the Write operation on the next rising edge of CLK.
