STM32F103CBT6 Erase Chip using ST-Link Utility

2023-11-09
Hi, I designed PCB including STM32F103CBT6 and I have attached schematic here as a reference. I am using SWD with an adapter from (Olimex LTD / ARM-JTAG-20-10) then connect through ST-LINK/VE debugger. After checking all voltage rails on the board, I...

STM32F103CBT6 Driving PWM for Synchronous DC/DC Buck Converter

2023-10-25
Hi,I am quite new to STM32 MCU family and have a quick question. I attached schematic for the reference. Is STM32F103CBT6 capable of driving complementary 50 kHz of PWM signals(HI and LO) with configurable duty cycle for the gate driver IC? Yes, I am...

STM32 Power supply ripple voltage

2023-10-20
Hi, What is acceptable ripple voltage on power supply pins on stm32? I am using DC/DC converter and have 100mVpkp at the output (+3.3V). I tied VDD and VDDA pin to one power supply as I am not planning to utilize an internal ADC. I am just planning t...

STM32F103CBT6 power consumption

2023-10-18
Hello, I recently designed STM32F103CBT6 based PCB for motor controller and I wanted to ask about power consumption at the default state of STM32F103CBT6. What is expected current consumption for just STM32F103CBT6 when I power up the board when not ...
