7 SUPPLY, RESET AND CLOCK MANAGEMENT
The device includes a range of utility features for
securing the application in critical situations (for
example in case of a power brown-out), and re-
ducing the number of external components.

7.1 INTERNAL RC OSCILLATOR ADJUSTMENT
The ST7 contains an internal RC oscillator with an
accuracy of 1% for a given device, temperature
and voltage. It must be calibrated to obtain the fre-
quency required in the application. This is done by
software writing a calibration value in the RCCR
(RC Control Register).
Whenever the microcontroller is reset, the RCCR
returns to its default value (FFh), i.e. each time the
device is reset, the calibration value must be load-
ed in the RCCR. Predefined calibration values are
stored in EEPROM for 3.0 and 5V V
ages at 25°C, as shown in the following table.

Caution: If the voltage or temperature conditions
change in the application, the frequency may need
to be recalibrated.

on how to calibrate the RC frequency using an ex-
