title: STMicroelectronics STM32 Factory-programmed data bindings

description: |
  This represents STM32 Factory-programmed read only non-volatile area: locked
  flash, OTP, read-only HW regs... This contains various information such as:
  analog calibration data for temperature sensor (e.g. TS_CAL1, TS_CAL2),
  internal vref (VREFIN_CAL), unique device ID...

          This property explicits a factory programmed area that both secure
          and non-secure worlds can access. It is needed when, by default, the
          related area can only be reached by the secure world.
