Notes:

1. All minimum and maximum values are guaranteed across the recommended operating conditions of supply voltage and

from –40 to +85 °C unless otherwise stated. All typical values apply at VDD = 3.3 V and 25 °C unless otherwise stated.

2. Microcontroller clock frequency tested in production at 1 MHz, 30 MHz, 32 MHz, and 32.768 kHz. Other frequencies

tested in bench characterization.

3. XTAL Range tested in production using an external clock source (similar to using a TCXO).
