Posted on December 30, 2017 at 16:23I started designing a product with a STM32L432KCU6. Looking at the datasheet I noticed that the HSI16 clock seems to be very accurate. From Figure 14, p 95, it seems that the clock is pretty much within 16MHz +/- ...

Posted on April 09, 2016 at 22:47I'm designing a product that uses the STM32F446. The reference manual states that Vcap is increased to 4.7uF (from 2.2uF for the F405) on page 15 and later on page 72 (power supply scheme) it lists 2 x 2.2uF caps on ...

Posted on January 06, 2016 at 13:35I'm looking at the STM32F446xx datasheet and on page 78 it specifies a minimum ''VDD rise time rate'' of 20uS/V, whereas the maximum is infinity. I assume this means using a slower supply with a longer rise time, e...

Posted on September 18, 2015 at 23:30I have been working on porting code for a STM32F405 based board to a newer board that uses the STM32F446. I have been having troubles getting USB to work. See [DEAD LINK /public/STe2ecommunities/mcu/Lists/cortex_...

Posted on September 14, 2015 at 18:40I'm working on a new board that uses the STM32F446 running at 180MHz. The board uses an external 16MHz oszillator and I would like to use ''PLLSAIP'' for the 48MHz USB clock. The clock configuration from STM32Cub...
