6.16 32kHz RC Oscillator (LFOSC)

Measured on a Texas Instruments reference design with Tc = 25°C, VDDS = 3.6V, unless otherwise noted.
MIN TYP MAX UNIT
Calibrated frequency 32.768 (1) kHz
(1) When using LFOSC as source for the low frequency system clock (LFCLK), the accuracy of the LFCLK derived Real Time Clock (RTC) can be improved by measuring LFOSC relative to HFXT and compensating for the RTC tick speed.
