SWITCHING CHARACTERISTICS
T
VL - VLR = 3.3 V, ±5%, 2.5 V, ±5%, or 1.8 V, ±5%
Input levels: Logic 0 = 0V = Low; Logic 1 = VD+ = High; CL = 15 pF.

SCLK(i)
Serial Port Timing in SEC Mode (SMODE = VLR)
SCLK(in) Pulse Width (High)
SCLK(in) Pulse Width (Low)
CS hold time (high) after RDY falling
CS hold time (high) after SCLK rising
CS low to SDO out of Hi-Z
Data hold time after SCLK rising

= -40 to +85 °C; V1+ = V2+ = +2.5 V, ±5%; V1- = V2- = -2.5 V, ±5%;
SDO
RDY
CS
15. SDO will be high impedance when CS is high. In some systems SDO may require a pull-down resistor.
