Industrial and Commercial Temperature Ranges
Description
The IDT709189 is a high-speed 64K x 9 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 IDT709189 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 1.2W of power.

NOTES: 1. "H" = VIH, "L" = VIL, "X" = Don't Care. 2. CE0 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 CE0 and CE 1. 5. The address counter advances if CNTEN = VIL on the rising edge of CLK, regardless of all other signals including CE0 and CE1. 6. While an external address is being loaded (ADS = VIL), R/W = VIH is recommended to ensure data is not written arbitrarily.

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. CE X = VIL means CE0X = VIL and CE1X = VIH CE X = VIH means CE0X = VIH or CE1X = VIL CE X < 0.2V means CE0X < 0.2V and CE 1X > VCC - 0.2V CE X > VCC - 0.2V means CE0X > VCC - 0.2V or CE1X < 0.2V "X" represents "L" for left port or "R" for right port. 6.
