Recommend alternative products of STM8S003 and STM8S103
This year, the price of ST Brand rises and the shortage is serious. which leads to the rapid increase of cost. Some alternative models are recommended.
- Silicon Labs EFM8BB1 MCU can perfectly replace STM8S003 and STM8S103.
- China Micro Semiconductor BAT32G133GC20SA can replace STM8L051F3P6.
