Functional Description

The FullFlex™ Dual-Port SRAM families consist of 4-Mbit,

9-Mbit, 18-Mbit, and 36-Mbit synchronous, true dual-port static

RAMs that are high-speed, low-power 1.8V/1.5V CMOS. Two

ports are provided, allowing the array to be accessed simulta-

neously. Simultaneous access to a location triggers determin-

istic access control. For FullFlex72 these ports can operate

independently with 72-bit bus widths and each port can be

independently configured for two pipeline stages. Each port

can also be configured to operate in pipeline or flow-through

mode.

Advanced features include built-in deterministic access

control to manage address collisions during simultaneous

access to the same memory location, variable impedance

matching (VIM) to improve data transmission by matching the

output driver impedance to the line impedance, and echo

clocks to improve data transfer.

To reduce the static power consumption, chip enables can be

used to power down the internal circuitry. The number of

cycles of latency before a change in CE0 or CE1 will enable

or disable the databus matches the number of cycles of read

latency selected for the device. In order for a valid write or read

to occur, both chip enable inputs on a port must be active.

Each port contains an optional burst counter on the input

address register. After externally loading the counter with the

initial address, the counter will increment the address inter-

nally.

Additional features of this device include a mask register and

a mirror register to control counter increments and

wrap-around, counter-interrupt (CNTINT) flags to notify that

the counter will reach the maximum value on the next clock

cycle, readback of the burst-counter internal address, mask

retransmit functionality, mailbox interrupt flags for message

passing, JTAG for boundary scan, and asynchronous Master

Reset (MRST). The logic block diagram in Figure 1 displays

these features.

The FullFlex72 is offered in a 484-ball plastic BGA package.

The FullFlex36 and FullFlex18 are offered in a 256-ball fine

pitch BGA package.

Selectable I/O Standard

The FullFlex families of devices also offer the option of

choosing one of four port standards for the device. Each port

can independently select standards from single-ended HSTL

class I, single-ended LVTTL, 2.5V LVCMOS, or 1.8V

LVCMOS. The selection of the standard is determined by the

PORTSTD pins for each port. These pins should be connected

to either an LVTTL or 2.5V LVCMOS power suppy. This will

determine the input clock, address, control, data, and Echo

clock standard for each port as shown in Table 2 .

Operating mode with different IO standards combined with

Clocking

Separate clocks synchronize the operations on each port.

Each port has one clock input C. In this mode, all the transac-

tions on the address, control, and data will be on the C rising

edge. All transactions on the address, control, data input,

output, and byte enables will occur on the C rising edge.

Selectable Pipeline/Flow-Through Mode

To meet data rate and throughput requirements, the FullFlex

families offer selectable pipeline or flow-through mode. Echo

clocks are not supported in flow-through mode and the DLL

must be disabled.

Flow-Through mode is selected by the FTSEL pin. Strapping

this pin HIGH selects pipeline mode. Strapping this pin LOW

selects flow-through mode.

DLL

The FullFlex familes of devices have an on-chip DLL. Enabling

the DLL reduces the clock to data valid time allowing more

set-up time for the receiving device. For operation below

100 MHz, the DLL must be disabled. This is selectable by

strapping LowSPD low. For information on DLL lock and reset

time, please see the Master Reset section below.

Echo Clocking

As the speed of data increases, on-board delays caused by

parasitics make providing accurate clock trees extremely

difficult. To counter this problem, the FullFlex families incor-

porate Echo Clocks. Echo Clocks are enabled on a per port

basis. The dual-port receives input clocks that are used to

clock in the address and control signals for a read operation.

The dual-port retransmits the input clocks relative to the data

output. The buffered clocks are provided on the CQ1/CQ1 and

CQ0/CQ0 outputs. Each port has a pair of Echo clocks. Each

clock is associated with half the data bits. The output clock will

match the corresponding ports I/O configuration.

To enable Echo clock outputs, tie CQEN HIGH. To disable

Echo clock outputs, tie CQEN LOW.

Deterministic Access Control

Deterministic Access Control is provided for ease of design.

The circuitry detects when both ports are accessing the same

location and provides an external BUSY flag to the port on

which data may be corrupted. The collision detection logic

saves the address in conflict (Busy Address) to a readable

address will be written to the Busy Address register.

If both ports are accessing the same location at the same time

and only one port is doing a write, if tCCS is met, then the data

being written to and read from the address is valid data. For

example, if the right port is reading and the left port is writing

and the left ports clock meets tCCS, then the data being read

from the address by the right port will be the old data. In the

same case, if the right ports clock meets tCCS, then the data

being read out of the address from the right port will be the new

data. In the above case, if tCCS is violated by the either ports

clock with respect to the other port and the right port gets the

external BUSY flag, the data from the right port is corrupted.

Table 5 shows the tCCS timing that must be met to guarantee

the data.

Table 6 shows that, in the case of the left port writing and the

right port reading, when an external BUSY flag is asserted on

the right port, the data read out of the device will not be

guaranteed.

The value in the busy address register can be read back to the

address lines. The required input control signals for this

function are shown in Table 9. The value in the busy address

amount of latency as a data read operation. After an initial

address match, the address under contention is saved in the

busy address register. All following address matches cause

the BUSY flag to be generated, however, none of the

addresses are saved into the busy address register. Once a

busy readback is performed, the address of the first match

which happens at least two clocks cycles after the busy

readback, is saved into the busy address register.

Variable Impedance Matching (VIM)

Each port contains a Variable Impedance Matching circuit to

set the impedance of the I/O driver to match the impedance of

the on-board traces. The impedance is set for all outputs

except JTAG and is done on a per port basis. To take

advantage of the VIM feature, connect a calibrating resistor

(RQ) that is five times the value of the intended line impedance

from the ZQ pin to VSS. The output impedance is then

adjusted to account for drifts in supply voltage and temper-

ature every 1024 clock cycles. If a port’s clock is suspended,

the VIM circuit will retain its last setting until the clock is

restarted where it will then resume periodic adjustment. In the

case of a significant change in device temperature or supply

voltage, the recalibration period is multiples of 1024 clock

cycles. A Master Reset will initialize the VIM circuitry. Ta ble 7

shows the VIM parameters and Table 8 describes the VIM

operation modes.

In order to disable VIM, the ZQ pin must be connected to

VDDIO of the relative supply for the I/Os before a Master

Reset.

Address Counter and Mask Register Operations[1]

Each port of the FullFlex family contains a programmable burst

address counter. The burst counter contains four registers: a

counter register, a mask register, a mirror register, and a busy

address register.

The counter register contains the address used to access the

RAM array. It is changed only by the master reset (MRST),

Counter Reset, Counter Load, Retransmit, and Counter

Increment operations.

The mask register value affects the Counter 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 only

changed by Mask Reset, Mask Load, and MRST. The Mask

Load operation loads the value of the address bus into the

mask register. The mask register defines the counting range

of the counter register. It divides the counter register into two

or three consecutive regions. Zero or more “0s” define the

masked region and one or more “1s” define the unmasked

portion of the counter register. The counter register may only

be divided into up to three regions. The region containing the

least significant bits must be no more than two bits. Bits one

and zero may be “10” respectively, masking the least signif-

icant counter bit and causing the counter to increment by two

instead of one. If bits one and zero are “00”, the two least

significant bits are masked and the counter will increment by

four instead of one. For example, in the case of a 256Kx72

configuration, a mask register value of 003FC divides the

mask register into three regions. With bit 0 being the least

significant bit and bit 17 being the most significant bit, the two

least significant bits are masked, the next eight bits are

unmasked, and the remaining bits are masked.

The mirror register is used to reload the counter register on

retransmit operations (see “retransmit” below) and wrap

functions (see “counter increment” below). The last value

loaded into the counter register is stored in the mirror register.

The mirror register is only changed by master reset (MRST),

Counter Reset, and Counter Load.

Table 9 summarizes the operations of these registers and the

required input control signals. All signals except MRST are

synchronized to the ports clock.

Counter Load Operation[1]

The address counter and mirror registers are both loaded with

the address value presented on the address lines. This value

ranges from 0 to 1FFFFF.

Mask Load Operation[1]

The mask register is loaded with the address value presented

on the address bus. This value ranges from 0 to 1FFFFF

though not all values permit correct increment operations.

Permitted values are in the form of 2n–1, 2n–2, or 2n–4. The

counter register can only be segmented in up to three regions.

From the most significant bit to the least significant bit,

permitted values have zero or more “0s”, one or more “1s”, and

the least significant two bits can be “11”, “10”, or “00”. Thus

1FFFFE, 07FFFF, and 003FFC are permitted values but

02FFFF, 003FFA, and 07FFE4 are not.

Counter Readback Operation

The internal value of the counter register can be read out on

the address lines. The address will be valid tCA after the

selected number of latency cycles configured by FTSEL. The

data bus (DQ) is tri-stated on the cycle that the address is

presented on the address lines. Figure 3 shows a block

diagram of the operation.

Mask Readback Operation

The internal value of the mask register can be read out on the

address lines. The address will be valid tCA after the selected

number of latency cycles configured by FTSEL. The data bus

(DQ) is tri-stated on the cycle that the address is presented on

the address lines. Figure 3 shows a block diagram of the

operation.

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 will reset the counter and mirror

registers to 00000.

Mask Reset Operation

The mask register is reset to all “1s”, which unmasks every bit

of the burst counter.

Increment Operation[1]

Once the address counter is initially loaded with an external

address, the counter can internally increment the address

value and address the entire memory array. Only the

unmasked bits of the counter register are incremented. In

order for a counter bit to change, the corresponding bit in the

mask register must be “1”. If the two least significant bits of the

mask register are “11”, the burst counter will increment by one.

If the two least significant bits are “10”, the burst counter will

increment by two, and if they are “00”, the burst counter will

increment by four. If all unmasked counter bits are incre-

mented to “1” and WRP is deasserted, the next increment will

wrap the counter back to the initially loaded value. The cycle

before an increment will result in the unmasked counter bits

being “1s”, a counter interrupt flag (CNTINT) is asserted if the

counter is continuously incrementing. The next increment will

cause the counter to reach its maximum value and the second

increment will return the counter register to its initial value

which was stored in the mirror register when WRP is

deasserted. When WRP is asserted, the second increment

after CNTINT is asserted will load the unmasked counter bits

with “0”. The example shown in Figure 4 shows an example of

the CYDD36S18V18 device with the mask register loaded with

a mask value of 00007F unmasking the seven least significant

bits. 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 000005 assuming WRP is

deasserted. The masked bits, the seventh address through the

twenty-first address, do not increment in an increment

operation. The counter address will start at address 000005

and will increment its internal address value until it reaches the

mask register value of 00007F. The counter wraps around the

memory block to location 000005 at the next count. CNTINT

is issued when the counter reaches the maximum –1 count.

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.

Retransmit

Retransmit allows repeated access to the same block of

memory without the need to reload the initial address. An

internal mirror register stores the address counter value last

loaded. When the burst counter reaches its maximum value

set by the mask register, it wraps back to the initial value stored

in the mirror register as long as WRP is deasserted. The

unmasked counter bits will be loaded with “0” If WRP is

asserted. If the counter is configured to continuously be in

increment mode, it increments once again to the maximum

value and wraps back to the value initially stored in the mirror

low, the counter will continue to wrap back to the value in the

mirror register independent of the state of WRP.

Counter Interrupt

The counter interrupt (CNTINT) is asserted LOW one clock

cycle before an increment operation that results in the

unmasked portion of the counter register being all “1s”. It is

deasserted by counter reset, counter load, mask reset, mask

load, and MRST.

Counting by Two

When the two least significant bits of the mask register are

“10,” the counter increments by two.

Counting by Four

When the two least significant bits of the mask register are

“00”, the counter increments by four.

Mailbox Interrupts

The upper two memory locations can be used for message

passing and permit communications between ports. Tabl e 10

shows the interrupt operation for both ports. The highest

memory location is the mailbox for the right port and the

maximum address – 1 is the mailbox for the left port.

When one port Writes to the other port’s mailbox, the INT flag

of the port that the mailbox belongs to is asserted LOW. The

INT flag remains asserted until the mailbox location is read by

the other port. When a port reads its mailbox, the INT flag is

deasserted high after one cycle of latency with respect to the

input clock of the port to which the mailbox belongs and is

independent of OE.

Table 10 shows that in order to set the INTR flag, a Write

operation by the left port to address 1FFFFF will assert INTR

LOW. A valid Read of the 1FFFFF location by the right port will

reset INTR HIGH after one cycle of latency with respect to the

right port’s clock. At least one byte enable has to be activated

to set or reset the mailbox interrupt.

Master Reset

The FullFlex family of Dual-Ports undergo a complete reset by

asserting MRST. The MRST can be asserted asynchronously

to the clocks and must remain asserted for at least tRS. Once

asserted MRST deasserts READY, initializes the internal burst

counters, internal mirror registers, and internal Busy

Addresses to zero, and initializes the internal mask register to

all “1s”. All mailbox interrupts (INT), Busy Address Outputs

(BUSY), and burst counter interrupts (CNTINT) are

deasserted upon master reset. Releasing MRST also signifies

that the power supplies and all port clocks are stable. This

begins calibration of the DLL and VIM circuits. READY will be

asserted within 1024 clock cycles. READY is a wired OR

capable output with a strong pull-up and weak pull-down. Up

to four outputs may be connected together. For faster

pull-down of the signal, connect a 250 Ohm resistor to VSS. If

the DLL and VIM circuits are disabled for a port, the port will

be operational within five clock cycles. However, the READY

will be asserted within 160 clock cycles.

IEEE 1149.1 Serial Boundary Scan (JTAG)

The FullFlex families incorporate an IEEE 1149.1 serial

boundary scan test access port (TAP). The TAP operates

using JEDEC-standard 3.3V or 2.5V I/O logic levels depending

on the VTTL power supply. It is composed of four input

connections and one output connection required by the test

logic defined by the standard.

Notes:

20. 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 C and

can be deasserted after that. Data will be out after the following C edge and will be tri-stated after the next C edge.

21. OE is “Don’t Care” for mailbox operation.

22. At least one of BE0, BE1, BE2, BE3, BE4, BE5, BE6, or BE7 must be LOW.

READ-to-WRITE for Pipelined Mode (OE = VIL)[37,38,39]

Notes:

37. When OE = VIL, the last read operation is allowed to complete before the DQ bus is tri-stated and the user is allowed to drive write data.

38. Two dummy writes should be issued to accomplish bus turnaround. The 3rd instruction is the first valid write.

39. Chip enable or all byte enables should be held inactive during the two dummy writes to avoid data corruption.
