Electrical Specifications
Two-wire Serial Bus Timing
The two-wire serial bus operation requires certain minimum master clock cycles
between transitions. These are specified in the following diagrams in master clock
cycles.
Figure 18: Serial Host Interface Start Condition Timing
Figure 19: Serial Host Interface Stop Condition Timing
Note: All timing are in units of master clock cycle.
Figure 20: Serial Host Interface Data Timing for Write
Note: SDATA is driven by an off-chip transmitter.
Figure 21: Serial Host Interface Data Timing for Read
Note: SDATA is pulled LOW by the sensor, or allowed to be pulled HIGH by a pull-up resistor off-
chip.
