Questions answered in these manuals

What is the typical start-up time for ceramic resonators with ST10F269?

Measurements show start-up times in the 0.05ms range.

From: AN1544 Application Note for ST10F269 Microcontroller

What is the minimum transconductance of the ST10F269 oscillator inverter?

The minimum transconductance (gm) of the ST10F269 oscillator inverter is 5 mA/V.

From: AN1544 Application Note for ST10F269 Microcontroller

What causes analog input signal error?

Analog input signal error can be caused by poor matching of source internal resistance with ADC input parameters, voltage drops due to leakage current, or noise from the analog input signal.

From: STMicroelectronics AN1538 Application Note

How can high frequency errors be avoided?

The input analog signal should always be low pass filtered to ensure that high frequencies are rejected during the sampling time.
