address register. After externally loading the counter with the
initial address the counter will self-increment the address inter-
nally (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 will power
down the internal circuitry to reduce the static power
consumption. One cycle is required with chip enables asserted
to reactivate the outputs.
The CY7C0430BV and CY7C0430CV (64K × 18 device)
supports burst contains for simple array partitioning. 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
Functional Description
The Quadport Datapath Switching Element (DSE) family offers
four ports that may be clocked at independent frequencies
from one another. Each port can read or write up to 133 MHz[1]
,
giving the device up to 10 Gb/s of data throughput. The device
is 1-Mb (64K × 18) in density. Simultaneous reads are allowed
for accesses to the same address location; however, simulta-
neous reading and writing to the same address is not allowed.
Any port can write to a certain location while other ports are
reading that location simultaneously, if the timing spec for port
to port delay (tCCS) is met. The result of writing to the same
location by more than one port at the same time is undefined.
Data is registered for decreased cycle time. Clock to data valid
t
CD2 = 4.2 ns. Each port contains a burst counter on the input

counter is loaded with an external address when the port’s
Counter Load pin (CNTLD) is asserted LOW. When the port’s
Counter Increment pin (CNTINC) is asserted, the address
counter will increment on each subsequent LOW-to- HIGH
transition of that port’s clock signal. This will read/write one
word from/into each successive address location until
CNTINC is deasserted. The counter can address the entire
switch array and will loop back to the start. Counter Reset
(CNTRST) is used to reset the burst counter. A counter-mask
register is used to control the counter wrap. The counter and
mask register operations are described in more details in the
following sections.
The counter or mask register values can be read back on the
bidirectional address lines by activating MKRD or CNTRD,
respectively.
The new features included for the QuadPort DSE family
include: readback of burst-counter internal address value on
address lines, counter-mask registers to control the counter
wrap-around, readback of mask register value on address
lines, interrupt flags for message passing, BIST, JTAG for
boundary scan, and asynchronous Master Reset.

Description
CNTRDP1
CNTRDP2
CNTRDP3
CNTRDP4
Counter Readback Input. When asserted LOW, the
internal address value of the counter will be read back on
the address lines. During CNTRD operation, both CNTLD
and CNTINC must be HIGH. Counter readback operation
has higher priority over mask register readback operation.
Counter readback operation is independent of port chip
enables. If address readback operation occurs with chip
enables active (CE0 = LOW, CE1 = HIGH), the data lines
(I/Os) will be three-stated. The readback timing will be
valid after one no-operation cycle plus tCD2 from the rising
edge of the next cycle.
MKRDP1
MKRDP2
MKRDP3
MKRDP4
Mask Register Readback Input. When asserted LOW,
the value of the mask register will be readback on address
lines. During mask register readback operation, all
counter and MKLD inputs must be HIGH (see Counter
and Mask Register Operations truth table). Mask register
readback operation is independent of port chip enables.
If address readback operation occurs with chip enables
active (CE0 = LOW, CE1 = HIGH), the data lines (I/Os) will
be three-stated. The readback will be valid after one
no-operation cycle plus tCD2 from the rising edge of the
next cycle.

INTP4
Counter Interrupt Flag Output. Flag is asserted LOW
for one clock cycle when the counter wraps around to
location zero.
Interrupt Flag Output. Interrupt permits communications
between all four ports. The upper four memory locations
can be used for message passing. Example of operation:
INTP4 is asserted LOW when another port writes to the
mailbox location of Port 4. Flag is cleared when Port 4
reads the contents of its mailbox. The same operation is
applicable to ports 1, 2, and 3.
TMS
JTAG Test Mode Select Input. It controls the advance of
JTAG TAP state machine. State machine transitions occur
on the rising edge of TCK.
TCK

JTAG Test Clock Input. This can be CLK of any port or
an external clock connected to the JTAG TAP.
JTAG Test Data Input. This is the only data input. TDI
inputs will shift data serially in to the selected register.

the mailbox for Port 1, FFFE is the mailbox for Port 2, FFFD is
the mailbox for Port 3, and FFFC is the mailbox for Port 4.
Table 3 shows that in order to set Port 1 INTP1 flag, a write by
any other port to address FFFF will assert INTP1 LOW. A read
of FFFF location by Port 1 will reset INTP1 HIGH. When one
port writes to the other port’s mailbox, the Interrupt flag (INT)
of the port that the mailbox belongs to is asserted LOW. The
Interrupt is reset when the owner (port) of the mailbox reads
the contents of the mailbox. The interrupt flag is set in a
flow-through mode (i.e., it follows the clock edge of the writing
port). Also, the flag is reset in a flow-through mode (i.e., it
follows the clock edge of the reading port).
Master Reset
The QuadPort DSE device undergoes a complete reset by
taking its Master Reset (MRST) input LOW. The Master Reset
input can switch asynchronously to the clocks. A Master Reset
initializes the internal burst counters to zero, and the counter
mask registers to all ones (completely unmasked). A Master
Reset also forces the Mailbox Interrupt (INT) flags and the
Counter Interrupt (CNTINT) flags HIGH, resets the BIST
controller, and takes all registered control signals to a
deselected read state.[50] A Master Reset must be performed
on the QuadPort DSE device after power-up.
Each port can read the other port’s mailbox without resetting
the interrupt. If an application does not require message
passing, INT pins should be treated as no-connect and should
be left floating. When two ports or more write to the same
mailbox at the same time INT will be asserted but the contents
of the mailbox are not guaranteed to be valid.
Interrupts
The upper four memory locations may be used for message
passing and permit communications between ports. Table 3
shows the interrupt operation for all ports. For the 1-Mb
QuadPort DSE device, the highest memory location FFFF is

Figure 1 provides a block diagram of the readback operation.
Table 2 lists control signals required for counter operations.
The signals are listed based on their priority. For example,
Master Reset takes precedence over Counter Reset, and
Counter Load has lower priority than Mask Register Load
(described below). All counter operations are independent of
Chip Enables (CE0 and CE1). When the address readback
operation is performed the data I/Os are three-stated (if CEs
are active) and one-clock cycle (no-operation cycle) latency is
experienced. The address will be read at time tCA2 from the
rising edge of the clock following the no-operation cycle. The
read back address can be either of the burst counter or the
mask register based on the levels of Counter Read signal
(CNTRD) and Mask Register Read signal (MKRD). Both
signals are synchronized to the port's clock as shown in
Table 2. Counter read has a higher priority than mask read.
Address Counter Control Operations
Counter enable inputs are provided to stall the operation of the
address input and utilize the internal address generated by the
internal counter for the fast interleaved memory applications.
A port’s burst counter is loaded with the port’s Counter Load
pin (CNTLD). When the port’s Counter Increment (CNTINC) 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
CNTINC is deasserted. Depending on the mask register state,
the counter can address the entire memory array and will loop
back to start. Counter Reset (CNTRST) is used to reset the
Burst Counter (the Mask Register value is unaffected). When
using the counter in readback mode, the internal address
value of the counter will be read back on the address lines
when Counter Readback Signal (CNTRD) is asserted.

Figure 2. Programmable Counter-Mask Register Operation[51]
The burst counter has a mask register that controls when and
where the counter wraps. An interrupt flag (CNTINT) is
asserted for one clock cycle when the unmasked portion of the
counter address wraps around from all ones (CNTINC must be
asserted) to all zeros. The example in Figure 2 shows the
counter mask register loaded with a mask value of 003F
unmasking the first 6 bits with bit “0” as the LSB and bit “15”
as the MSB. The maximum value the mask register can be
loaded with is FFFF. 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 XXX8.
The “blocked” addresses (in this case, the 6th address through
the 15th address) are loaded with an address but do not
increment once loaded. The counter address will start at
address XXX8. With CNTINC asserted LOW, the counter will
increment its internal address value till it reaches the mask
register value of 3F and wraps around the memory block to
location XXX0. Therefore, the counter uses the mask-register
to define wrap-around point. The mask register of every port
is loaded when MKLD (mask register load) for that port is
LOW. When MKRD is LOW, the value of the mask register can
be read out on address lines in a manner similar to counter
read back operation (see Table 2 for required conditions).
When the burst counter is loaded with an address higher than
the mask register value, the higher addresses will form the
masked portion of the counter address and are called blocked
addresses. The blocked addresses will not be changed or
affected by the counter increment operation. The only
exception is mask register bit 0. It can be masked to allow the
address counter to increment by two. If the mask register bit 0
is loaded with a logic value of “0,” then address counter bit 0
is masked and can not be changed during counter increment
operation. If the loaded value for address counter bit 0 is “0,”
the counter will increment by two and the address values are
even. If the loaded value for address counter bit 0 is “1,” the
counter will increment by two and the address values are odd.
This operations allows the user to achieve a 36-bit interface
using any two ports, where 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 36-bit word in even memory locations, and the other half
in odd memory locations. CNTINT will be asserted when the
unmasked portion of the counter wraps to all zeros. Loading
mask register bit 0 with “1” allows the counter to increment the
address value sequentially.
Table 2 groups the operations of the mask register with the
operations of the address counter. Address counter and mask
register signals are all synchronized to the port's clock CLK.
Master reset (MRST) is the only asynchronous signal listed on
Table 2. Signals are listed based on their priority going from
left column to right column with MRST being the highest. A
LOW on MRST will reset both counter register to all zeros and
mask register to all ones. On the other hand, a LOW on
CNTRST will only clear the address counter register to zeros
and the mask register will remain intact.
There are four operations for the counter and mask register:
1. Load operation: When CNTLD or MKLD is LOW, the ad-
dress counter or the mask register is loaded with the ad-
dress value presented at the address lines. This value rang-
es from 0 to FFFF (64K). The mask register load operation
has a higher priority over the address counter load opera-
tion.
2. Increment: Once the address counter is loaded with an
external address, the counter can internally increment the
address value by asserting CNTINC LOW. The counter can
Note:

CY7C0430CV
address the entire memory array (depend on the value of
the mask register) and loop back to location 0. The
increment operation is second in priority to load operation.
3. Readback: the internal value of either the burst counter or
themask register can be readout on the addresslines when
CNTRD or MKRD is LOW. Counter readback has higher
priority over mask register readback. A no-operation delay
cycle is experienced when readback operation is
Test Data-In (TDI)
The TDI pin is used to serially input information into the
registers and can be connected to the input of any of the
registers. The register between TDI and TDO is chosen by the
instruction that is loaded into the TAP instruction register. For
information on loading the instruction register, see the TAP
Controller State Diagram. TDI is internally pulled up and can
be unconnected if the TAP is unused in an application. TDI is
connected to the most significant bit (MSB) on any register.
performed. The address will be valid after tCA2 (for counter
readback) or tCM2 (for mask readback) from the following
port's clock rising edge. Address readback operation is
independent of the port's chip enables (CE0 and CE1). If
address readback occurs while the port is enabled (chip
enables active), the data lines (I/Os) will be three-stated.
4. Hold operation: In order to hold the value of the address
counter at certain address, all signals in Table 2 have to be
HIGH. This operation has the least priority. This operation
is useful in many applications where wait states are needed
or when address is available few cycles ahead of data.
Test Data Out (TDO)
The TDO output pin is used to serially clock data-out from the
registers. The output is active depending upon the current
state of the TAP state machine (see TAP Controller State
Diagram (FSM)). The output changes on the falling edge of
TCK. TDO is connected to the least significant bit (LSB) of any
register.
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 QuadPort DSE device and may be performed while the
device is operating. At power-up, the TAP is reset internally to
ensure that TDO comes up in a High-Z state.
The counter and mask register operations are totally
independent of port chip enables.
IEEE 1149.1 Serial Boundary Scan (JTAG) and
Memory Built-In-Self-Test (MBIST)
TAP Registers
The CY7C0430BV and CY7C0430CV incorporate a serial
boundary scan test access port (TAP). This port is fully
compatible with IEEE Standard 1149.1-2001[52]. The TAP
operates using JEDEC standard 3.3V I/O logic levels. It is
composed of three input connections and one output
connection required by the test logic defined by the standard.
Memory BIST circuitry will also be controlled through the TAP
interface. All MBIST instructions are compliant to the JTAG
standard. An external clock (CLKBIST) is provided to allow the
user to run BIST at speeds up to 50 MHz. CLKBIST is multi-
plexed internally with the ports clocks during BIST operation.
Registers are connected between the TDI and TDO pins and
allow data to be scanned into and out of the QuadPort DSE
device test circuitry. Only one register can be selected at a
time through the instruction registers. Data is serially loaded
into the TDI pin on the rising edge of TCK. Data is output on
the TDO pin on the falling edge of TCK.
Instruction Register
Four-bit instructions can be serially loaded into the instruction
register. This register is loaded when it is placed between the
TDI and TDO pins as shown in the following JTAG/BIST
Controller diagram. Upon power-up, the instruction register is
loaded with the IDCODE instruction. It is also loaded with the
IDCODE instruction if the controller is placed in a reset state
as described in the previous section.
When the TAP controller is in the CaptureIR state, the two least
significant bits are loaded with a binary “01” pattern to allow for
fault isolation of the board level serial test path.
Disabling the JTAG Feature
It is possible to operate the QuadPort DSE device without
using the JTAG feature. To disable the TAP controller, TCK
must be tied LOW (VSS) to prevent clocking of the device. TDI
and TMS are internally pulled up and may be unconnected.
They may alternately be connected to VDD through a pull-up
resistor. TDO should be left unconnected. CLKBIST must be
tied LOW to disable the MBIST. Upon power-up, the device will
come up in a reset state which will not interfere with the
operation of the device.
Bypass Register
To save time when serially shifting data through registers, it is
sometimes advantageous to skip certain devices. The bypass
register is a single-bit register that can be placed between TDI
and TDO pins. This allows data to be shifted through the
QuadPort DSE device with minimal delay. The bypass register
is set LOW (VSS) when the BYPASS instruction is executed.
Test Access Port (TAP)–Test Clock (TCK)
The test clock is used only with the TAP controller. All inputs
are captured on the rising edge of TCK. All outputs are driven
from the falling edge of TCK.
Test Mode Select
Boundary Scan Register
The TMS input is used to give commands to the TAP controller
and is sampled on the rising edge of TCK. It is allowable to
leave this pin unconnected if the TAP is not used. The pin is
pulled up internally, resulting in a logic HIGH level.
The boundary scan register is connected to all the input and
output pins on the QuadPort DSE device. The boundary scan
register is loaded with the contents of the QuadPort DSE
device Input and Output ring when the TAP controller is in the
Capture-DR state and is then placed between the TDI and
TDO pins when the controller is moved to the Shift-DR state.
Note:
52. Master Reset will reset the JTAG controller.
Document #: 38-06027 Rev. *B
Page 26 of 37
CY7C0430BV
CY7C0430CV
The EXTEST, and SAMPLE/PRELOAD instructions can be
used to capture the contents of the Input and Output ring.
The user must be aware that the TAP controller clock can only
operate at a frequency up to 10 MHz, while the QuadPort DSE
device clock operates more than an order of magnitude faster.
Because there is a large difference in the clock frequencies, it
is possible that during the Capture-DR state, an input or output
will undergo a transition. The TAP may then try to capture a
signal while in transition (metastable state). This will not harm
the device, but there is no guarantee as to the value that will
be captured. Repeatable results may not be possible.
To guarantee that the boundary scan register will capture the
correct value of a signal, the QuadPort DSE device signal
must be stabilized long enough to meet the TAP controller’s
capture set-up plus hold times. Once the data is captured, it is
possible to shift out the data by putting the TAP into the
Shift-DR state. This places the boundary scan register
between the TDI and TDO pins. If the TAP controller goes into
the Update-DR state, the sampled data will be updated.
Identification (ID) Register
The ID register is loaded with a vendor-specific, 32-bit code
during the Capture-DR state when the IDCODE command is
loaded in the instruction register. The IDCODE is hardwired
into the QuadPort DSE device and can be shifted out when the
TAP controller is in the Shift-DR state. The ID register has a
vendor code and other information described in the Identifi-
cation Register Definitions table.
TAP Instruction Set
Sixteen different instructions are possible with the 4-bit
instruction register. All combinations are listed in Table 6,
Instruction Codes. Seven of these instructions (codes) are
listed as RESERVED and should not be used. The other nine
instructions are described in detail below.
The TAP controller used in this QuadPort DSE device is fully
compatible[52] with the 1149.1 convention. The TAP controller
can be used to load address, data or control signals into the
QuadPort DSE device and can preload the Input or output
buffers. The QuadPort DSE device implements all of the
1149.1 instructions except INTEST. Table 6 lists all instruc-
tions.
BYPASS
When the BYPASS instruction is loaded in the instruction
register and the TAP is placed in a Shift-DR state, the bypass
register is placed between the TDI and TDO pins. The
advantage of the BYPASS instruction is that it shortens the
boundary scan path when multiple devices are connected
together on a board.
Instructions are loaded into the TAP controller during the
Shift-IR state when the instruction register is placed between
TDI and TDO. During this state, instructions are shifted
through the instruction register through the TDI and TDO pins.
To execute the instruction once it is shifted in, the TAP
controller needs to be moved into the Update-IR state.
CLAMP
The optional CLAMP instruction allows the state of the signals
driven from QuadPort DSE device pins to be determined from
the boundary-scan register while the BYPASS register is
selected as the serial path between TDI and TDO. CLAMP
controls boundary cells to 1 or 0.
EXTEST
CYBIST
EXTEST is a mandatory 1149.1 instruction which is to be
executed whenever the instruction register is loaded with all 0s.
EXTEST allows circuitry external to the QuadPort DSE device
package to be tested. Boundary-scan register cells at output pins
are used to apply test stimuli, while those at input pins capture
test results.
CYBIST instruction provides the user with a means of running
a user-accessible self-test function within the QuadPort DSE
device as a result of a single instruction. This permits all
components on a board that offer the CYBIST instruction to
execute their self-tests concurrently, providing a quick check
for the board. The QuadPort DSE device MBIST provides two
modes of operation once the TAP controller is loaded with the
CYBIST instruction:
IDCODE
The IDCODE instruction causes a vendor-specific, 32-bit code
to be loaded into the identification register. It also places the
identification register between the TDI and TDO pins and
allows the IDCODE to be shifted out of the device when the
TAP controller enters the Shift-DR state. The IDCODE
instruction is loaded into the instruction register upon
power-up or whenever the TAP controller is given a test logic
reset state.
Non-Debug Mode (Go-NoGo)
The non-debug mode is a go-nogo test used simply to run
BIST and obtain pass-fail information after the test is run. In
addition to that, the total number of failures encountered can
be obtained. This information is used to aid the debug mode
(explained next) of operation. The pass-fail information and
failure count is scanned out using the JTAG interface. An
MBIST Result Register (MRR) will be used to store the
pass-fail results. The MRR is a 25-bit register that will be
connected between TDI and TDO during the internal scan
(INT_SCAN) operation. The MRR will contain the total number
of fail read cycles of the entire MBIST sequence. MRR[0] (bit
0) is the Pass/Fail bit. A “1” indicates some type of failure
occurred, and a “0” indicates entire memory pass.
High-Z
The High-Z instruction causes the bypass register to be
connected between the TDI and TDO pins when the TAP
controller is in a Shift-DR state. It also places all QuadPort
DSE device outputs into a High-Z state.
SAMPLE/PRELOAD
In order to run BIST in non-debug mode, the two-bit MBIST
Control Register (MCR) is loaded with the default value “00”,
and the TAP controller’s finite state machine (FSM), which is
synchronous to TCK, transitions to Run Test/Idle state. The
entire MBIST test will be performed with a deterministic
SAMPLE/PRELOAD is a 1149.1 mandatory instruction. When
the SAMPLE/PRELOAD instructions loaded into the
instruction register and the TAP controller in the Capture-DR
state, a snapshot of data on the inputs and output pins is
captured in the boundary scan register.

data is from LSB to MSB. MDR[25:10] represent the failing
address (MSB to LSB). The state of the BIST controller is
scanned out using MDR[9:4]. Bit 2 is the Test Done bit. A “0”
in bit 2 means test not complete. The user has to monitor this
bit at every packet to determine if more failure packets need to
be scanned out at the end of the BIST operations. If the value
is “0” then BIST must be repeated to capture the next failing
packet. If it is “1,” it means that the last failing packets have
been scanned out. A trailer similar to the header represents
the end of a packet.

CYC[CLKBIST]
--------------------------------------------

CYC[TCK]
tCYC is total number of TCK cycles required to run MBIST.
SPC is the Synchronization Padding Cycles (4–6 cycles).
m is a constant represents the number of read and write opera-
tions required to run MBIST algorithms (31195136).
Once the entire MBIST sequence is completed, supplying
extra TCK or CLKBIST cycles will have no effect on the MBIST
controller state or the pass-fail status.
MCR_SCAN
This instruction will connect the Memory BIST Control
Register (MCR) between TDI and TDO. The default value
(upon master reset) is “00.” Shift_DR state will allow modifying
the MCR to extend the MBIST functionality.
Debug Mode
With the CYBIST instruction loaded and the MCR loaded with
the value of “01,” and the FSM transitions to RUN_TEST/IDLE
state, the MBIST goes into CYBIST-debug mode. The debug
mode will be used to provide complete failure analysis infor-
mation at the board level. It is recommended that the user runs
the non-debug mode first and then the debug mode in order to
save test time and to set an upper bound on the number of
scan outs that will be needed. The failure data will be scanned
out automatically once a failure occurs using the JTAG TAP
interface. The failure data will be represented by a 100-bit
packet given below. The 100-bit Memory Debug Register
(MDR) will be connected between TDI and TDO, and will be
shifted out on TDO, which is synchronized to TCK.
MBIST Control States
Thirty-five states are listed in Table 7. Four data algorithms are
used in debug mode: moving inversion (MIA), march_2 (M2A),
checkerboard (CBA), and unique address algorithm (UAA).
Only Port 1 can write MIA, M2A, and CBA data to the memory.
All four ports can read any algorithm data from the QuadPort
DSE device memory. Ports 2, 3, and 4 will only write UAA data.
Boundary Scan Cells (BSC)
Table 9 lists all QuadPort DSE family I/Os with their associated
BSC. Note that the cells have even numbers. Every I/O has
two boundary scan cells. Bidirectional signals (address lines,
datalines) require two cells so that one (the odd cell) is used
to control a three-state buffer. Input only and output only
signals have an extra dummy cell (odd cells) that are used to
ease device layout.
Figure 3 is a representation of the 100-bit MDR packet. The
packet follows a two-bit header that has a logic “1” value, and
represents two TCK cycles. MDR[97:26] represent the BIST
comparator values of all four ports (each port has 18 data
lines). A value of “1” indicates a bit failure. The scanned out
