• Manufacturer Part Number: IDT70V07
• Description: 32k X 8 3.3v Dual-port
• Manufacturer: Integrated Device Technology

Waveform of Read Cycles
NOTES:
1. Timing depends on which signal is asserted last, OE or CE.
2. Timing depends on which signal is de-asserted first, CE or OE.
3. t
4. Start of valid data depends on which timing becomes effective last t
5. SEM = V
AC Electrical Characteristics Over the
Operating Temperature and Supply Voltage
NOTES:
1. Transition is measured 0mV from Low or High impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. To access RAM, CE = V
4. The specification for t
5. 'X' in part number indicates power rating (S or L).
