But in the long run, 1pF XCAP is less to avoid the external noise. So we are thinking to start-up the crystal after power up …
WebFeb 16, 2013 · Feb 13, 2013. #6. To add support to comments above. A low power microcontroller tends not to use a crystal because it takes so long, 10s of milliseconds, to start. Have to use an RC oscillator. Not a problem when just powered up and used, but if woken up every 10-20-50 or whatever milliseconds then just doesn't work. WebStart-up time too long. I've noticed that the in my application the start-up time, i.e. the time from power-up to the first instruction in main () is about 7 to 8 ms. This seems very long to me. I'm using a STM32F103RC and the IAR compiler. I changed system_stm32f10x.c so it configures the STM32 to run with HSI at start-up by …
WebDec 29, 2024 · In the prior art, the start-up time of the crystal resonator 105 is shortened by injection from an energy source i.e. the RC oscillator 101. An accurate reference RC oscillator 101 (with a frequency close to the crystal resonator frequency) is used to initially force the crystal resonator 105 and buildup signal amplitude.

As a consequence of this, the crystal start-up time is non-deterministic. It depends on the circuit in which the device is placed, the type and amount of decoupling and very much on the way the power comes up1. grantchester tv series 7
