TMF8701 − Detailed Description
TOF Description
System Parameters
The on-chip microprocessor is a Cortex M0 μP.
Figure 11:
ARM M0 Parameters
Standard I²C Timing for 1MHz Fast Mode Plus with lower drive.
The default TOF address is 0x41.
The address can be changed after power-up. Use the enable pin
to enable only one device at a time to provide a unique device
addresses.
