Hi Team,We are using STM32F103RDT6 MCU, for connecting 5V RS485 transceiver to the MCU. We used (PIN no 16,17) USART2(RX-PA3,TX-PA2)and one GPIO (PIN no 15) pins of MCU. Kindly clarify the below points1. From the datasheet,it shows all pins are 5V to...

Hi,In the STM32F103RDT6 , The datsheet showing VDDA pin needs 10nf AND 1Uf. But in AN2586 reference document, it shows 100nf and 1Uf. which one is correct?Warm regards,Monisha OM

I have one doubt ,While programming I make USART3 pin (29,30) to either push pull or into other default state. Is this USART pin is 5V tolerant on that time, because the datasheet shows "voltage higher than VDD+0.3 the internal pull-up/pull-down resi...

Hi,Thanks for response.The VIH(min)of transceiver is 2. So can I proceed with those 5V tolerant UART pins?R48 and R49 used for EMI purpose, which is DNP. If there any signal issue,we will cut the trace and mount that resistor.warm regards,Monisha om

Thank you berendi for your response.Now we are updated our circuit with Pin 29 (PB10-TX1) and Pin 30(PB11-RX1)is used, which is 5V tolerant pin. Please find the image of the circuit.In the datasheet its shows "For 5V tolerant pin, In order to sustain...

Hi, Iam using AZ1117CH-3.3V LDO for convering 5 to 3.3V.In the datasheet it shows 10nf needed for VDDA pin, is it 10nf or 100nf? Also for the 8MHz crystal, what is the use of REXT mention on the datasheet.Is it mandatory?

Hi,Thank you for your response. I have one more doubt.What is the function of tamper_RTC pin. As in my case, I am not using any RTC. so can I make that pin float or use as GPIO? Do that pin have any default function.Warm regards,Monisha OM
