New possibilities for the ultra-low power segment!

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...


Hello Everyone. I am trying to build a Universal gateway. which will be the best Microcontroller to work on considering the memory and interfaces for communication.

In this gateway we would like to keep communication of WIFI,ETHERNET, BLE,GSM module. Also data will be stored into the device. There will be a configuration tool to configure the gateway. Data can be received via RS232, RS485, ADC,BLE and then proce...
