Device configuration
The STPMIC1 has a non-volatile memory (NVM) that enables scalability to support a wide range of applications:
•
Default output voltage, POWER_UP/POWER_DOWN sequence, protection behavior, auto turn-on
functionality, I2C slave address
•
The STPMIC1A, STPMIC1B, STPMIC1D and STPMIC1E are pre-programmed devices to support the
STM32MP1 series application processor versions
•
The STPMIC1C is not a programmed device to support custom applications
•
Straightforward NVM (re)programming via I2C to facilitate mass production directly in target applications

The start-up sequence is split into four steps (Rank0 to Rank3).
Each BUCK converter or LDO regulator can be programmed to be automatically turned ON in one of these
phases:
•
Rank= 0: rail not turned ON automatically, no output voltage appears after POWER-UP
•
Rank= 1: rail automatically turned ON after 7 ms following a Turn_ON condition
•
Rank= 2: rail automatically turned ON after further 3 ms
•
Rank= 3: rail automatically turned ON after further 3 ms
Whatever the STPMIC1 version:
•
AUTO_TURN_ON option is set
•
Boost and switches cannot be turned ON automatically
