IDT70V3569S
High-Speed 16K x 36 Dual-Port Synchronous Pipelined Static RAM
Description:
Industrial and Commercial Temperature Ranges
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.
The 70V3569 can support an operating voltage of either 3.3V or
2.5V on one or both ports, controllable by the OPT pins. The power
supply for the core of the device (VDD) remains at 3.3V.
The IDT70V3569 is a high-speed 16K x 36 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. With an input data register, the IDT70V3569 has been
optimized for applications having unidirectional or bidirectional data flow

NOTES:
1. All VDD pins must be connected to 3.3V power supply.
2. All VDDQ pins must be connected to appropriate power supply: 3.3V if OPT pin for that port is set to VIH (3.3V), and 2.5V if OPT pin for that port is
set to VIL (0V).
3. All VSS pins must be connected to ground supply.
4. Package body is approximately 28mm x 28mm x 3.5mm.

NOTES:
1. VDD, OPTX, and VDDQX must be set to appropriate operating levels prior to
applying inputs on the I/Os and controls for that port.
2. OPTX selects the operating voltage levels for the I/Os and controls on that port.
If OPTX is set to VIH (3.3V), then that port's I/Os and controls will operate at 3.3V
levels and VDDQX must be supplied at 3.3V. If OPTX is set to VIL (0V), then that
port's I/Os and controls will operate at 2.5V levels and VDDQX must be supplied
at 2.5V. The OPT pins are independent of one another—both ports can operate
at 3.3V levels, both can operate at 2.5V levels, or either can operate at 3.3V
with the other at 2.5V.

NOTES:
1. "H" = VIH, "L" = VIL, "X" = Don't Care.
2. Read and write operations are controlled by the appropriate setting of R/W, CE0, CE1, BEn and OE.
3. Outputs are in Pipelined mode: the data out will be delayed by one cycle.
4. ADS and CNTRST are independent of all other memory control signals including CE0, CE 1 and BEn
5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other memory control signals including CE0, CE1, BEn.

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) = 120mA (Typ).
5. CEX = V IL means CE 0X = V IL and CE1X = VIH
CEX = VIH means CE0X = VIH or CE1X = VIL
CEX < 0.2V means CE0X < 0.2V and CE1X > VCC - 0.2V
CEX > VCC - 0.2V means CE0X > VCC - 0.2V or CE1X - 0.2V
"X" represents "L" for left port or "R" for right port.

1. OE is asynchronously controlled; all other inputs are synchronous to the rising clock edge.
2. ADS = VIL, CNTEN and CNTRST = VIH.
3. The output is disabled (High-Impedance state) by CE0 = VIH, CE1 = VIL, BEn = VIH following the next rising edge of the clock. Refer to
Truth Table 1.
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. If BEn was HIGH, then the appropriate Byte of DATAOUT for Qn + 2 would be disabled (High-Impedance state).

NOTES:
1. B1 Represents Device #1; B2 Represents Device #2. Each Device consists of one IDT70V3569 for this waveform,
and are setup for depth expansion in this example. ADDRESS(B1) = ADDRESS(B2) in this situation.
2. BEn, OE, and ADS = VIL; CE 1(B1), CE 1(B2), R/W, CNTEN, and CNTRST = VIH.

NOTES:
1. CE0, BEn, and ADS = VIL; CE1, CNTEN, and CNTRST = VIH.
2. OE = VIL for the Right Port, which is being read from. OE = V IH for the Left Port, which is being written to.
3. If tCO < minimum specified, then data from right port read is not valid until following right port clock cycle (ie, time from write to valid read on opposite port will
be tCO + 2 tCYC2 + tCD2 ). If tCO > minimum, then data from right port read is available on first right port clock cycle (ie, time from write to valid read on opposite
port will be tCO + tCYC + tCD2 ).

NOTES:
1. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals.
2. CE0, BEn, and ADS = V IL; CE1, CNTEN, and CNTRST = V IH. "NOP" is "No Operation".
3. 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.
4. "NOP" is "No Operation." Data in memory at the selected address may be corrupted and should be re-written to guarantee data integrity.

1. CE0, BEn, and R/W = V IL; CE1 and CNTRST = VIH.
2. CE0, BEn = 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: ADDR 0 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.

IDT70V3569S
High-Speed 16K x 36 Dual-Port Synchronous Pipelined Static RAM
Industrial and Commercial Temperature Ranges
Functional Description
Depth and Width Expansion
The IDT70V3569 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 stall
the operation of the address counters for fast interleaved
memory applications.
A HIGH on CE0 or a LOW on CE1 for one clock cycle will power down
the internal circuitry to reduce static power consumption. Multiple chip
enables allow easier banking of multiple IDT70V3569s for depth expansion configurations. Two cycles are required with CE0 LOW and CE1
HIGH to re-activate the outputs.
The IDT70V3569 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
various chip enables in order to expand two devices in depth.
The IDT70V3569 can also be used in applications requiring expanded
width, as indicated in Figure 4. Through combining the control signals, the
devices can be grouped as necessary to accommodate applications
needing 72-bits or wider.
