32 kHz RC Oscillator (RCOSC_LF)

Measured on a Texas Instruments reference design with Tc = 25 °C, VDDS = 3.0 V, unless otherwise noted.
MIN TYP MAX UNIT
Frequency 32.8 kHz
Calibrated RTC variation(1) Calibrated periodically against XOSC_HF(2) ±600(3) ppm
Temperature coefficient 50 ppm/°C
When using RCOSC_LF as source for the low frequency system clock (SCLK_LF), the accuracy of the SCLK_LF-derived Real Time Clock (RTC) can be improved by measuring RCOSC_LF relative to XOSC_HF and compensating for the RTC tick speed. This functionality is available through the TI-provided Power driver.
TI driver software calibrates the RTC every time XOSC_HF is enabled.
Some device's variation can exceed 1000 ppm. Further calibration will not improve variation.
