Device configuration table

The STPMIC25 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, and an I²C slave address.

•

The STPMIC25A and STPMIC25B are preprogrammed devices to support the STM32MP2 series

application processor versions.

•

Straightforward NVM reprogramming via I²C to facilitate mass production directly in target applications.

•

Possibility to lock NVM content to prevent further reprogramming by writing LOCK_NVM bit.

All output voltages with Rank = 0 are, by default, programmed with 0 Dec, (refer to Table 19 and Table 20.

The startup sequence is split into four steps (Rank0 to Rank5).

Each BUCK converter or LDO regulator can be programmed to be automatically turned ON in one of these

phases. Each rank phase is separated by a delay (1.5 ms, 3 ms, 4.5 ms, or 6 ms) programmed in the NVM:

•

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 a further 1.5 ms (by default)

•

Rank = 3: rail automatically turned ON after a further 1.5 ms (by default)

•

Rank = 4: rail automatically turned ON after a further 1.5 ms (by default)

•

Rank = 5: rail automatically turned ON after a further 1.5 ms (by default)

Whatever the STPMIC25 version, the AUTO_TURN_ON option is set.
