SDR AC Characteristics

Notes:

1. Only applicable as a constraint for WRR or WRAR instruction when SRWD is set to a 1.

2. Full VDD range & CL=30 pF.

3. Full VDD range & CL=15 pF.

4. Output HI-Z is defined as the point where data is no longer driven.

tCS and tDIS require additional time when the Reset feature and Quad mode are enabled (CR2V[5]=1 and CR1V[1]=1).

6. Tentative AC parameters, subject to device characterization, as DDP has increased I/O capacitance that may modify values slightly.
