Hello all,I am using the STM32L071KB in a project, and I have to write a 32 bit word in internal EEPROM each minute; So is it worth changing the address of this 32 bit word after 100 000 cycles, in order to increase number of Erase/Write cycles ?If t...

Hello Eleon,Thanks for the proposal; in fact this was an issue with the TAP_CFG register (a new bit has been created, MSB of this register, which must be set to 1 in order to validate all the interrupts...).Have a nice day !

Hello,it works now : there was a bit to set in the TAP-CFG register of the LSM6DS3TR-C, in order to activate all the interrupts (bit which doesn't exist in the LSM6DS3).anyway, thanks for your help !Best regardsOlivier

Hello,I have also a problem when replacing the LSM6DS3 with the LSM6DS3TR-C : the INT1 pad of the LSM6DS3TR-C is never set to '1', whatever kind of interrupt I configure.The INT1 pad is configured in push-pull.Do you have any idea about this problem?...

Hi,ST support just answered us :the EEPROM in STM32L071 is organized by words (4 bytes) and erase operation erases only selected word. Thus 100k cycles is valid per each word separately.And they confirm that we can write several millions of times th...

Hi JW,Yes, this si exactly the problem; we don't know if erasing a 32 bit word erases in fact just the 32 bit word, or a whole page (buffered in RAM and writed back to Flash).I have asked 2 days agao to ST support, but no answer yet...

Hello, I have replaced LSM6DS3 with the LSM6DS3TR-C, but the INT1 pad of the LSM6DS3TR-C is nevers set to '1', whatever kind of interrupt I send. The INT1 pad is configured in push-pull. Is there anybody faced to this problem? Thank you !

Increase EEPROM Erase/Write cycles capability for STM32L0

Re: My Board fails test due to use of LSM6DS3TR-C. Can someone help me with detailed comparison of LSM6DS3TR & LSM6DS3TR-C?
