Linear Burst Sequence Table (LBO=VSS)
Synchronous Write Function Truth Table(1, 2)
Asynchronous Truth Table(1)
Interleaved Burst Sequence Table (LBO=VDD)
NOTES:
1. L = VIL, H = VIH, X = Don’t Care.
2.
BW3 and BW4 are not applicable for the IDT71V35781.
3. Multiple bytes may be selected during the same cycle.
NOTES:
1. L = VIL, H = VIH, X = Don’t Care.
2. Synchronous function pins must be biased appropriately to satisfy operation requirements.
NOTE:
1. Upon completion of the Burst sequence the counter wraps around to its initial state.
