IDT70V35/34S/L (IDT70V25/24S/L)
High-Speed 3.3V 8/4K x 18 (8/4K x 16) Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
Timing Waveform of Semaphore Read after Write Timing, Either Side(1)
Timing Waveform of Semaphore Write Contention(1,3,4)
NOTES:
1. DOR = DOL = VIL,
CER = CEL = VIH, or both UB & LB = VIH.
2. All timing is the same for left and right port. Port “A” may be either left or right port. Port “B” is the opposite from port “A”.
3. This parameter is measured from R/
W"A" or SEM"A" going HIGH to R/W"B" or SEM"B" going HIGH.
4. If tSPS is not satisfied, there is no guarantee which side will obtain the semaphore flag.
NOTES:
1.
CE = VIH or UB & LB = VIH for the duration of the above timing (both write and read cycle).
2. “DATAOUT VALID” represents all I/O's (I/O0-I/O17 for IDT70V35/34) and (I/O0-I/O15 for IDT70V25/24) equal to the semaphore value.
