SLVSD02D March 2015 – June 2019 TPS65982
A single flash can be used for two TPS65982’s in a system where the primary TPS65982 is connected to the flash and the seoncdary TPS65982 is connected to the primary through UART. UART data is used to pass the firmware from the primary TPS65982 to the secondary TPS65982 in the system. Figure 82 shows a simplified block diagram of how a primary and secondary TPS65982 are connected using a single flash. The primary TPS65982 must have its I2C_ADDR pin tied to GND with a 0Ω to denote it as the primary TPS65982.
