STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on November 14, 2014 at 10:39On stm32f407, Erasing a 128KB flash sector takes about 1 second, but after I finished erasing 1 sector, the systick just happend for 3 times(3 milliseconds), as I config systick as 1000Hz.Does MCU disable systick ...
Posted on November 14, 2014 at 00:18Hello ST gurus! Our company is seeking to protect its IP as much as possible from code extraction before products are shipped. We understand the STM32F4xx has protective features to prevent code extraction via JTA...

Posted on November 14, 2014 at 14:53Hi I am using STM32F205 for my project (SN8000 EVK from Murata).The SN8000 EVK uses Wiced SDK but it supports all the libraryfunctions, so the basic configurations will work(It uses vector tables in the vector_ta...
Posted on October 16, 2014 at 12:25Hello all,I'm attempting to talk to two devices, a barometer (MS5611) and a magnetometer (HMC5883L), using I2C with DMA on an STM32F4. The barometer runs on a timer (10ms), while the magnetometer runs through an in...
Posted on November 14, 2014 at 14:55Hello,Will the STM32L0 series (48 pin LQFP package) ever have more than 8K of RAM? - or is it an unchangeable design limit.I'm presently using the STM32L151 series and the 32K RAM is proving very useful for audio ...
Posted on November 14, 2014 at 14:40As far as I can see the new STM32Cube has callbacks that are called from the ISRs. This means that all variables that can be changed within the callback and accessed from outside the callback has to be declared as...
