TIMING DIAGRAM: SPI WRITE DATA TRANSFER Figure 12

DS1722

*SCLK can be either polarity, timing shown for CPOL = 1.

NOTES:

1. All voltages are referenced to ground.

2. Logic 0 voltages are specified at a sink current of 3 mA.

3. Logic 1 voltages are specified at a source current of 1 mA.

4. ICC specified with SCLK=VDDD and CE=GND. Typical ICC1 is 0.25 µA and ICC is 0.3 mA at 25°C

and VDDD = 2.65V.

5. Measured at VIH =0.7 VDDD or VIL=0.2 VDDD and 10 ms maximum rise and fall time.

6. Measured with 50 pF load

7. Measured at VOH =0.7 VDDD or VOL =0.2 VDDD. Measured from the 50% point of SCLK to the VOH

minimum of SDO.
