STM32 MCUs Products

What is the maximum Flash clock freqency of STM32H743?

Is it possible to drive the controller with 480 MHz and therefor the flash with 240 MHz?How many waitstates have to be set at 240 MHz?

STM32L5xx OctoSPI Read/Write to Xilinx FPGA Configuration Using SelectMAP

Hi. I want to use the OctoSPI to configure Xilinx FPGAs (e.g., Kintex-7) in the SelectMAP mode. Therefore I need 8 data bits, a chip select (CSn), a RD/nWR signal and a CLK to the FPGA. I know the OctoSPI is usually used for reading and writing to Q...

SPI communication between Slave and Master

This is my first post on this QnA section and i hope i would be getting help from the community. What i want to implement is a simple communication between 2 STM32 (both are F1 series in this case) using a SPI. Both the MCU are configured using CubeM...

Better learning resources for Bluenrg-2?

Hey, folks.How are you people learning how to use the capabilities of your MCUs? In particular, I am trying to program a Bluenrg-2 board for a temperature control application. I would like to get better information on using the Multi-Function Timer...

STM32F3 - how does exactly SYSCFG_CFGR1.ENCODER_MODE work?

SYSCFG_CFGR1.ENCODER_MODE is a two-bit bitfield, which - besides a "no remap" apparently allows a remap, documented as TIMx IC1 and TIMx IC2 are connected to TIM15 IC1 and TIM15 IC2 where TIMx is TIM2, TIM3 and TIM4 for the various setting of bitfiel...

AES-CBC(128 bit) Encryption for STM32H750VB IC

I am using STM32h750VB for a Project. I need to use AES -CBC Mode of Encryption.I have downloaded the cube-cryptolib and when I searched for the crypto code of my IC, I found that the AES CBC code is available for STM32H743ZI-Nucleo..Can i use the sa...

What's the bXCAN RXD recessive signal on STM32L476?

I'm reading RM0351 for STM32L476, "To be synchronized the hardware has to monitor a sequence of 11 consecutive recessive bits on the CAN RX signal." Is RX recessive bit a digital high or low signal? I couldn't find the info on the datasheet which onl...

My data are being send in loop despite the datas are ACK.
