Sensor And Detector Interfaces FAQ

How is the device address programmed?

The device supports both runtime programmable addressing via daisy chain and pre-programmed nonvolatile memory storage using the Read/Write NVM command.

What is the function of the H_CAP pin?

The H_CAP pin connects to an external holding capacitor that stores energy during bus idle periods to supply current to the device and external sensors during signaling.

Can the I/O pins be used for analog input?

Yes, all four I/O pins can be configured by the central MCU as analog-to-digital inputs, logic inputs, or logic outputs.
