• Manufacturer Part Number: IDT70V9289L12PF
• Description: HIGH-SPEED 3.3V 64K x18/x16 SYNCHRONOUS PIPELINED DUAL-PORT STATIC RAM
• Manufacturer: IDT [Integrated Device Technology]

Timing Waveform of a Bank Select Pipelined Read
Timing Waveform with Port-to-Port Flow-Through Read
NOTES:
1. B1 Represents Bank #1; B2 Represents Bank #2. Each Bank consists of one IDT70V9389 or IDT70V9289 for this waveform, and are setup for depth expansion
2. UB, LB, OE, and ADS = V
3. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
4. CE
5. OE = V
6. If t
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".
