Description

The IDT709289 is a high-speed 64K x 16 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 IDT709289 has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE 0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. Fabricated using CMOS high-performance technology, these devices typically operate on only 1.2W of power.

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. V TERM must not exceed V cc + 10% for more than 25% of the cycle time or 10ns maximum, and is limited to < 20mA for the period of VTERM > Vcc + 10%. Absolute Maximum Ratings(1) NOTES: 1. These parameters are determined by device characterization, but are not production tested. 2. 3dV references the interpolated capacitance when the input and output switch from 0V to 3V or from 3V to 0V. 3. C OUT also references CI/O. Capacitance(1) (TA = +25°C, f = 1.0MHz) NOTES: 1. This is the parameter T A. This is the "instant on" case temperature. NOTES: 1. V TERM must not exceed V cc + 10%. 2.

"H" = V IH, "L" = VIL, "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 is independent of all other signals including CE 0, 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.

6.42 IDT709289L High-Speed 64K x 16 Synchronous Pipelined Dual-Port Static RAM Industrial and Commercial Temperature Ranges NOTES: 1. At f = f MAX, 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 = 25°C for Typ, and are not production tested. I CC 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.

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 = V IL, 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 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. 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.

CE0, UB, LB, and R/W = VIL; CE1 and CNTRST = VIH. 2. CE0, UB, LB = VIL; CE1 = VIH. 3.

A READ or WRITE cycle may be coincidental with the counter reset cycle. 7. CNTEN = V IL advances Internal Address from ‘An’ to ‘An +1’.
