SWITCHING CHARACTERISTICS - CONTROL PORT - SPI™ FORMAT

(For CQZ, TA = -10 to +70° C; For DQZ, TA = -40 to +85° C; VA = 5 V, VD =VLS= 3.3 V; VLC = 1.8 V to 5.25 V;

Inputs: Logic 0 = DGND, Logic 1 = VLC, CL =30 pF)

Notes:

20. Data must be held for sufficient time to bridge the transition time of CCLK.

21. For fsck <1 MHz.
