SLVSCO4D July 2015 – February 2019 TPS65917-Q1
The TPS65917-Q1 device has two, exclusive selectable (from factory settings) interfaces; 2 high-speed I2C interfaces (I2C1_SCL_SCK or I2C1_SDA_SDI and I2C2_SCL_SCE or I2C2_SDA_SDO) or 1 SPI (I2C1_SCL_SCK, I2C1_SDA_SDI, I2C2_SDA_SDO, or I2C2_SCL_SCE). Both are used to fully control and configure the device and have access to all the registers. When the I2C configuration is selected (either I2C1_SCL_SCK or I2C1_SDA_SDI) a general purpose control (GPC) interface is dedicated to configure the device and the I2C2_SCL_SCE or I2C2_SDA_SDO interface, dynamic voltage scaling (DVS) is dedicated to dynamically change the output voltage of the SMPS converters. The DVS I2C interface has access only to the voltage scaling registers of the SMPS converters (R/W mode).
