IDT709169/59L High-Speed 16/8K x 9 Synchronous Pipelined Dual-Port Static RAM
Preliminary Industrial and Commercial Temperature Ranges
Description
The IDT709169/59 is a high-speed 16/8K x 9 bit synchronous DualPort 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 IDT709169/59 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 925mW of power.

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. Vcc = 5V, TA = 25C for Typ, and are not production tested. ICC DC(f=0) = 150mA (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 > 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.

5653 tbl 11 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 characterization, but is not production tested. 2. The Pipelined output parameters (tCYC2, tCD2) to either the Left or 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 or CE1 = VIL following the next rising edge of the clock. Refer to Truth Table 1. 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. "X" here denotes Left or Right port. The diagram is with respect to that port.

NOTES: 1. B1 Represents Bank #1; B2 Represents Bank #2. Each Bank consists of one IDT709169/59 for this waveform, and are setup for depth expansion in this example. ADDRESS(B1) = ADDRESS(B2) in this situation. 2. OE and ADS = VIL; CE1(B1), CE1(B2), R/W, CNTEN, and CNTRST = VIH. 3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 4. CE0 and ADS = VIL; CE1, CNTEN, and CNTRST = VIH. 5. OE = VIL for the Right Port, which is being read from. OE = VIH for the Left Port, which is being written to. 6. If tCCS < maximum specified, then data from right port READ is not valid until the maximum specified for tCWDD. If tCCS > maximum specified, then data from right port READ is not valid until tCCS + tCD1. tCWDD does not apply in this case. 7. All timing is the same for both Left and Right ports. Port "A" may be either Left or Right port. Port "B" is the opposite from Port "A".

NOTES: 1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). 2. Output state (High, Low, or High-impedance) is determined by the previous cycle control signals. 3. CE0 and ADS = VIL; CE1, CNTEN, and CNTRST = VIH. "NOP" is "No Operation". 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. "NOP" is "No Operation." Data in memory at the selected address may be corrupted and should be re-written to guarantee data integrity.

NOTES: 1. CE0 and R/W = VIL; CE1 and CNTRST = VIH. 2. CE0 = 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. 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.

A .unctional Description
The IDT709169/59 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. CE0 = VIH or CE1 = VIL for one clock cycle will power down the internal circuitry to reduce static power consumption. Multiple chip enables allow easier banking of multiple IDT709169/59's for depth expansion configurations. When the Pipelined output mode is enabled, two cycles are required to get valid data on the outputs.
Depth and Width Expansion
The IDT709169/59 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 IDT709169/59 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 18-bit or wider applications.
