(2) The frequency drift is included and measured from the trimmed frequency at VREG25 = 2.5 V, TA = 25°C. (3) The startup time is defined as the time it takes for the oscillator output frequency to be ±3% of the typical oscillator frequency. 6.16 High-Frequency Oscillator 2.4 V < VREG25 < 2.6 V; typical values at TA = 25°C and VREG25 = 2.5 V (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT fOSC Operating frequency 8.389 MHz fEIO Frequency error(1) (2) TA = 0°C to 60°C –2.0% 0.38% 2.0% TA = –20°C to 70°C –3.0% 0.38% 3.0% TA = –40°C to 85°C -4.5% 0.38% 4.5% tSXO Start-up time(3) TA = –40°C to 85°C 2.5 5 ms (1) The frequency drift is included and measured from the trimmed frequency at VREG25 = 2.5 V, TA = 25°C. (2) The frequency error is measured from 32.768 kHz. (3) The startup time is defined as the time it takes for the oscillator output frequency to be ±3% of the typical oscillator frequency. 6.17 Low-Frequency Oscillator 2.4 V < VREG25 < 2.6 V; typical values at TA = 25°C and VREG25 = 2.5 V (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT f(LOSC) Operating frequency 32.768 kHz f(LEIO) Frequency error(1) (2) TA = 0°C to 60°C –1.5% 0.25% 1.5% TA = –20°C to 70°C –2.5% 0.25% 2.5% TA = –40°C to 85°C -4.0% 0.25% 4.0% t(LSXO) Start-up time(3) TA = –40°C to 85°C 500 μs |
