Configurable to Fxtal or Fxtal
divided by 2, 3, 7.5, 10, 15, or
30 where Fxtal is the reference
XTAL frequency. In addition,
32.768 kHz is also supported.
Programmable setting
Start-up time will vary with
XTAL type and board layout.

Notes:
1. All minimum and maximum values are guaranteed across the recommended operating conditions of supply voltage and
from –45 to +85 °C unless otherwise stated. All typical values apply at Vdd=3.3V and 25C unless otherwise stated.
2. Microcontroller clock frequency tested in production at 1 MHz, 30 MHz, 32 MHz, and 32.768 kHz. Other frequencies
tested by bench characterization.
3. XTAL Range tested in production using an external clock source (similar to using a TCXO).
