Bug Report: STM32CubeProgrammer fails to program bank 2 of smaller dual bank STM32L4 devices

2019-10-03
Anybody have a solution to this?STM32CubeProgrammer fails to re-program Bank 2 of STM32L476RC devices (256 kB FLASH), unless the device is blank (ie: after a Mass Erase). I suspect this has to do with the sector number jumping from 63 to 256 when th...

STM32 I2C Multi-master Hardware Bug

2018-03-19
Posted on March 19, 2018 at 19:39Hello,I am reporting a hardware bug with the I2C peripheral in the newer STM32 families (STM32F7, STM32H7, STM32L0, STM32L4, and STM32L4+ familes) in I2C multi-master mode (including many SMBus host applications), an...

STM32 TIM2 ARR requires 32-bit access

2015-02-05
Posted on February 05, 2015 at 21:30 Hello, I found some unexpected behaviour with the 32-bit TIM2 module on STM32F4xx devices, and many others. When accessing the TIM2->ARR (a 32-bit timer) register, 16-bit writes have the following behaviou...

STM32L Max Voltage to FT pin while unpowered

2014-07-31
Posted on August 01, 2014 at 02:45Can someone confirm if applying ~5.0V to a 5V tolerant pin on an STM32L151 while unpowered (VDD=0.0V) will damage it?The latest datasheets specify the Absolute Maximum Ratings are VDD+4.0V for FT pins, but bench tes...
