70 / 103 page  Electrical parameters STM8L052C6 70/103 DocID023331 Rev 2 LSE crystal/ceramic resonator oscillator The LSE clock can be supplied with a 32.768 kHz crystal/ceramic resonator oscillator. All the information given in this paragraph is based on characterization results with specified typical external components. In the application, the resonator and the load capacitors have to be placed as close as possible to the oscillator pins in order to minimize output distortion and startup stabilization time. Refer to the crystal resonator manufacturer for more details (frequency, package, accuracy...). Figure 13. LSE oscillator circuit diagram Table 29. LSE oscillator characteristics Symbol Parameter Conditions Min Typ Max Unit fLSE Low speed external oscillator frequency - - 32.768 - kHz RF Feedback resistor V = 200 mV - 1.2 - M C(1) Recommended load capacitance (2) -- 8 - pF IDD(LSE) LSE oscillator power consumption -- - 1.4(3) µA VDD = 1.8 V - 450 - nA VDD = 3 V - 600 - VDD = 3.6 V - 750 - gm Oscillator transconductance - 3(3) -µA/V tSU(LSE) (4) Startup time VDD is stabilized - 1 - s 1. C=CL1=CL2 is approximately equivalent to 2 x crystal CLOAD. 2. The oscillator selection can be optimized in terms of supply current using a high quality resonator with a small Rm value. Refer to crystal manufacturer for more details. 3. Data guaranteed by Design. Not tested in production. 4. tSU(LSE) is the startup time measured from the moment it is enabled (by software) to a stabilized 32.768 kHz oscillation. This value is measured for a standard crystal resonator and it can vary significantly with the crystal manufacturer.
