Firma STMicroelectronics začala s výrobou novej MCU rodiny STM8L.
Ako sa dá očakávať, ide o ultra-low- power verziu a vysoko-výkonné 8-bitové jadro.

Táto rodina bude obsahovat tri hlavné produktové línie:

Vývojové nástroje
STMicroelektronics ponúka k procesorom aj


Softwérovo je na vývoj určený Free ST Visual Develop (STVD), ktorý v spojení s Cosmic C Compilerom, alebo Raisonance C compiler (oboje free do 16K kódu) predstavuje pekné vývojové IDE.
Taktiež je možné použiť Ride7 od Raisonance, ktorý s už obsiahnutým C komilérom a RBuilder-om vygeneruje zadarmo kód do veľkost 16K. Tento nástroj obsahuje aj CodeCompressor, ktorý je schopný zredukovať výsledný kód o 5-15% .
