Resolved! Can someone identify this IC?

I would have thought the text on it would prove to be meaningful but apparently according to every search I have tried it is not. Thanks for your help.

Temperature of the internal temperature sensor

Using STM32F0308C on a custom board. When I read the temperature sensor I am getting 1765 and the TS_CAL value is 1778.Supply voltage is 3.3V, VREF_INT is 1524 and I am reading 1525 on the internal reference. So I assume I must apply a 1524/1525 corr...

I am using STM32F030c8t6 in my device which is battery operated. I want to monitor a standard 3.7V Lipo battery voltage so I used a voltage divider at the battery and divider output is set to 3.3V which goes to ADC pin of Controller.

1. Is it ok to set 3.3V as a divider output which goes to ADC pin?2. The external voltage at VDDA pin (We have given the same VDD as VDDA) show some fluctuations while ADC monitoring so can you suggest the best possible way to monitor battery voltage...

Mismatch datasheet reset value and reality

Dear community,I am using the STM32F103C8T6 32 bit ARM Cortex M3 microcontroller.In Section 9.2.1 in the reference manual (GPIOx Control Register Low) it says that the reset value is 0x4444 4444 (which means all pins are floating inputs).However, whe...

Timers frequency divided by 2

Hello everybody!I try to configure TIM2 to interrupt in the range of 100Hz ... 1kHz. Strangely, the actual frequency I set is divided by 2: if I configure the timer to run at 1000Hz, it will run at 500HzTIM2 configuration:void System::InitTimers() ...

Minimum ADC Sample Times

Looking at the datasheet for STM32F20xxx ADC; if I run the ADC at 30MHz and use the minimum sample time of 3 (100ns), the input sample capacitor will not be fully charged even with zero source resistance. The input spec is 6K and 4pF, if you take th...

Timer Configuration causes Flash Error

I've got a real strange error, and I really don't understand it. I'm using a STM32F407VET6 Microcontroller. I also use CubeMX to generate the configurations. But especially with the Timers, it's not possible to set every setting I need with Cube, so ...
