STM8L151C8U6

[sguec.1]

Hello , 

Can you help me for the microntroleur reference

 1) Why don't you recommend this product for new designs ?

2) Do you have an idea of the number of years before the end of its life ?

3) NRND information available in an PCN ? 

Thank you in advance

Welcome, @sguec.1​, to the community!

1. The STM8s will be discontinued in 2032 because they can no longer be produced at break-even, which is why there is already a reference to NRND. This gives everyone enough time to switch to alternative devices (e.g. the STM32C0).
2. see 1.
3. A PCN is a Product Change Notification. Since nothing is changed in the product until it is discontinued, there is no PCN.

Does it answer your questions?

Regards

Bad news that STM8 will be discontinued because it is a powerful MCU.

It have EEPROM with 128 bytes page write capability. This is also valid for FLASH. It have better code density than ARM and needs less instructions. We can do a 16-bits comparison with just 3 bytes of code, We can inc/dec/test/clear memory directly without using a register and with a single instruction. We can clear/set/toggle a GPIO bit with just 4 bytes of code. It have RLC, RRC and DIV instructions. It have 24MB of address space!

Also ARM GCC optimization is not the best.

I believe that many people without knowing the power of this MCU, ignore it just because it is a 8-bit MCU.

it is done

I agree that STM8 is a really powerful µC. IMO it is one of the best 8-bit architectures I''ve seen so far. In particular, it is a good target for C compilers.

 

Fortunately, STM8S and STM8L are now back to "active", no longer "NRND"!
