Hello,

My team and I are designing a product using the STM8S003F3. 

We connect to a host controller using SPI. This works great!

Now I want to enable firmware update functionality. I started to get into SWIM protocol when I began to notice perhaps SPI can handle this as well. I can't seem to find which bootloader version is used in this chip to verify. I'm thinking this is because the chip doesn't feature a bootloader?

If that's the case will SWIM still be suitable?

The SMT8S003 does not features built in bootloader:

(See the 6th page from the DocID14798)

The device is capable of flash self programming, but you will need to write your own bootloader.
