32-bit ARM Cortex-M33 microcontroller

11.6 FRO (32 KHz)

[1]

Typical ratings are not guaranteed. The values listed are at room temperature (25

C), nominal supply

voltages.

11.7 RTC oscillator

See Section 13.3 for connecting the RTC oscillator to an external clock source.

[1]

Parameters are valid over operating temperature range unless otherwise specified.

11.8 I2C-bus

[1]

Guaranteed by design. Not tested in production.

[2]

Parameters are valid over operating temperature range unless otherwise specified. See the I2C-bus specification UM10204 for details.

[3]

tHD;DAT is the data hold time that is measured from the falling edge of SCL; applies to data in transmission and the acknowledge.
