SNAS678B May 2018 – May 2019 HDC2080
To communicate with the HDC2080, the master must first address slave devices through a slave address byte. The slave address byte consists of seven address bits and a direction bit that indicates the intent to execute a read or write operation. The HDC2080 features an address pin to allow up to 2 devices to be addressed on a single bus. Table 1 describes the pin logic levels used to connect up to two devices. ADDR should be set before any activity on the interface occurs and remain constant while the device is powered up.
