57 / 82 page ![]() SPC560D30x, SPC560D40x Electrical characteristics Doc ID 16315 Rev 5 57/82 4.16 Slow internal RC oscillator (128 kHz) electrical characteristics The device provides a 128 kHz slow internal RC oscillator (SIRC). This can be used as the reference clock for the RTC module. Table 40. Slow internal RC oscillator (128 kHz) electrical characteristics Symbol C Parameter Conditions(1) Value(2) Unit Min Typ Max fSIRC CC P Slow internal RC oscillator low frequency TA = 25 °C, trimmed — 128 — kHz SR — — 100 — 150 ISIRC (3) CC C Slow internal RC oscillator low frequency current TA = 25 °C, trimmed — — 5 µA tSIRCSU CC P Slow internal RC oscillator start-up time TA = 25 °C, VDD = 5.0 V ± 10% — 8 12 µs ΔSIRCPRE CC C Slow internal RC oscillator precision after software trimming of fSIRC TA = 25 °C −2— 2 % ΔSIRCTRIM CC C Slow internal RC oscillator trimming step —— 2.7 — ΔSIRCVAR CC P Slow internal RC oscillator variation in temperature and supply with respect to fSIRC at TA = 55 °C in high frequency configuration High frequency configuration −10 — 10 % 1. VDD = 3.3 V ± 10% / 5.0 V ± 10%, TA = −40 to 125 °C, unless otherwise specified. 2. All values need to be confirmed during device validation. 3. This does not include consumption linked to clock tree toggling and peripherals consumption when RC oscillator is ON. |
