6.3.4.2 Serial Interface

The OPT3001-Q1 device operates as a target device on both the I2C bus and SMBus. Connections to the bus are made using the SCL clock input line and the SDA open-drain I/O line. The OPT3001-Q1 device supports the transmission protocol for standard mode (up to 100kHz), fast mode (up to 400kHz), and high-speed mode (up to 2.6MHz). All data bytes are transmitted most-significant bits first.

The SDA and SCL pins feature integrated spike-suppression filters and Schmitt triggers to minimize the effects of input spikes and bus noise. See the Section 8.1.1 section for further details of the I2C bus noise immunity.
