(1) For smaller coin cell batteries, with high worst-case end-of-life equivalent source resistance, a 22-µF VDDS input capacitor (see
Figure 7-1) must be used to ensure compliance with this slew rate.
(2) Applications using RCOSC_LF as sleep timer must also consider the drift in frequency caused by a change in temperature (see
Section 5.11).
(3) TA = â40°C to +105°C, VDDS = 1.8 V to 3.8 V, unless otherwise noted.
5.22 Switching Characteristics
Measured on the TI CC2640Q1EM-7ID reference design with Tc = 25°C, VDDS = 3.0 V, unless otherwise noted.
