13. Electrical Characteristics: General (Continued)
All parameters refer to GND and are valid for T_amb = 25°C, V_{VS3V_AVCC} = V_VS5V = 3V, and V_VS5V = 5V. Typical values are given at
f_RF = 315 MHz unless otherwise specified. Details about current consumption, timing, and digital pin properties can be found in the
specific sections of the “Electrical Characteristics”.
