Description:
The IDT70V9369 is a high-speed 16K x 18 bit synchronous
Dual-Port RAM. The memory array utilizes Dual-Port memory cells
to allow simultaneous access of any address from both ports.
Registers on control, data, and address inputs provide minimal setup
and hold times. The timing latitude provided by this approach allows
systems to be designed with very short cycle times.
Pin Configuration(1,2,3)
NOTES:
1. All VDD pins must be connected to power supply.
2. All VSS pins must be connected to ground.
3. Package body is approximately 14mm x 14mm x 1.4mm.
4. This package code is used to reference the package diagram.
5. This text does not indicate orientation of the actual part-marking.
With an input data register, the IDT70V9369 has been optimized for
applications having unidirectional or bidirectional data flow in bursts. An
automatic power down feature, controlled by CE0 and CE1, permits the
on-chip circuitry of each port to enter a very low standby power mode.
Fabricated using IDT’s CMOS high-performance technology, these
devices typically operate on only 500mW of power.

NOTES:
1. "H" = VIH, "L" = V IL, "X" = Don't Care.
2. ADS, CNTEN, CNTRST = X.
3. OE is an asynchronous input signal.

NOTES:
1. LB and UB are single buffered regardless of state of FT/PIPE.
2. CE0 and CE1 are single buffered when FT/PIPE = VIL,
CE0 and CE1 are double buffered when FT/PIPE = VIH, i.e., the signals
take two cycles to deselect.

Truth Table II—Address Counter Control(1,2,6)
NOTES:
1. "H" = VIH, "L" = V IL, "X" = Don't Care.
2. CE0, LB, UB, and OE = VIL; CE1 and R/W = VIH.
3. Outputs configured in Flow-Through Output mode; if outputs are in Pipelined mode the data out will be delayed by one cycle.
4. ADS and CNTRST are independent of all other signals including CE0, CE1, UB and LB.
5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other signals including CE0, CE1, UB and LB.
6. While an external address is being loaded (ADS = VIL), R/W = VIH is recommended to ensure data is not written arbitrarily.
NOTES:
1. VIL > -1.5V for pulse width less than 10 ns.
2. VTERM must not exceed VDD +0.3V.
NOTES:
1 . Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may
cause permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated
in the operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect reliability.
2. VTERM must not exceed VDD +0.3V.
3. Ambient Temperature Under DC Bias. No AC Conditions. Chip deselect.
NOTES:
1. This is the parameter TA. This is the "instant on" case temperature.

DC Electrical Characteristics Over the Operating

NOTE:
1. At VDD < 2.0V input leakages are undefined.
NOTES:
1. At f = fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency clock cycle of 1/tCYC, using "AC TEST CONDITIONS" at input
levels of GND to 3V.
2. f = 0 means no address, clock, or control lines change. Applies only to input at CMOS level standby.
3. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
4. VDD = 3.3V, TA = 25°C for Typ, and are not production tested. IDD DC(f=0) = 90mA (Typ).
5. CEX = VIL means CE0X = VIL and CE1X = VIH
CEX = VIH means CE0X = VIH or CE1X = VIL
CEX < 0.2V means CE0X < 0.2V and CE1X > VDD - 0.2V
CEX > VDD - 0.2V means CE0X > VDD - 0.2V or CE1X < 0.2V
"X" represents "L" for left port or "R" for right port.

NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). This parameter is guaranteed by device characteriza-
tion, but is not production tested.
2. The Pipelined output parameters (tCYC2, tCD2) apply to either or both the Left and Right ports when FT/PIPE = VIH. Flow-through parameters (tCYC1, tCD1) apply
when FT/PIPE = VIL for that port.
3. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (OE), FT/PIPER, and FT/PIPEL.

NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
2. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
3. ADS = VIL, CNTEN and CNTRST = VIH.
4. The output is disabled (High-Impedance state) by CE0 = VIH, CE1 = VIL, UB = VIH, or LB = VIH following the next rising edge of the clock. Refer to Notes under
Pin Names Table.
5. 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 use only.
6. If UB or LB was HIGH, then the Upper Byte and/or Lower Byte of DATAOUT for Qn + 2 would be disabled (High-Impedance state).
7. "X' here denotes Left or Right port. The diagram is with respect to that port.

Timing Waveform of Counter Reset (Pipelined Outputs)(2)
NOTES:
1. CE0, UB, LB, and R/W = VIL; CE1 and CNTRST = VIH.
2. CE0, UB, LB = VIL; CE1 = VIH.
3. The "Internal Address" is equal to the "External Address" when ADS = VIL and equals the counter output when ADS = VIH.
4 . 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 use only.
5. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
6. No dead cycle exists during counter reset. A READ or WRITE cycle may be coincidental with the counter reset cycle. ADDR0 will be accessed. Extra cycles
are shown here simply for clarification.
7. CNTEN = VIL advances Internal Address from ‘An’ to ‘An +1’. The transition shown indicates the time required for the counter to advance.
The ‘An +1’ Address is written to during this cycle.

Depth and Width Expansion
The IDT70V9369 features dual chip enables (refer to Truth Table I)
in order to facilitate rapid and simple depth expansion with no requirements
for external logic. Figure 4 illustrates how to control the varioius chip
enables in order to expand two devices in depth.
The IDT70V9369 can also be used in applications requiring expanded
width, as indicated in Figure 4. Since the banks are allocated at the
discretion of the user, the external controller can be set up to drive the input
signals for the various devices as required to allow for 36-bit or wider
applications.

Figure 4. Depth and Width Expansion with IDT70V9369
Functional Description
The IDT70V9369 provides a true synchronous Dual-Port Static RAM
interface. Registered inputs provide minimal set-up and hold times on
address, data, and all critical control inputs. All internal registers are clocked
on the rising edge of the clock signal, however, the self-timed internal write
pulse is independent of the LOW to HIGH transition of the clock signal.
An asynchronous output enable is provided to ease asynchronous
bus interfacing. Counter enable inputs are also provided to staff the
operation of the address counters for fast interleaved memory applications.
CE0 = VIL and CE1 = VIH for one clock cycle will power down the
internal circuitry to reduce static power consumption. Multiple chip enables
allow easier banking of multiple IDT70V9369's for depth expansion
configurations. When the Pipelined output mode is enabled, two cycles are
required with CE0 = VIL and CE1 = VIH to re-activate the outputs.
