LSE oscillator circuit diagram Internal clock sources Subject to general operating conditions for VDD, and TA. High speed internal RC oscillator (HSI) In the following table, data are based on characterization results and are not tested in production, unless otherwise specified. Table 34. HSI oscillator characteristics Symbol Parameter Conditions(1) 1. VDD = 3.0 V, TA = -40 to 125 °C unless otherwise specified. Min Typ Max Unit fHSI Frequency VDD = 3.0 V - 16 - MHz ACCHSI HSI oscillator user trimming accuracy Trimmed by the application for any VDD and TA conditions -1 - 1 % HSI oscillator accuracy (factory calibrated) VDD ≤ 1.8 V ≤ VDD ≤ 3.6 V, -40 °C ≤ TA ≤ 125 °C -5 - 5 TRIM HSI user trimming step(2) 2. The trimming step differs depending on the trimming code. It is usually negative on the codes which are multiples of 16 (0x00, 0x10, 0x20, 0x30...0xE0). Refer to the AN3101 “STM8L05xxx/15xxx, STM8L162xx and STM8AL31xx/3Lxx internal RC oscillator calibration” application note for more details.
