Dramatically reduce time and cost to built STM8AF and STM8AL-based
systems certied to ISO 26262 Functional Safety standard
Functionnal Safety Package
for STM8A 8-bit Automotive MCUs
STM8A-SafeASIL
WHY CHOOSE
STM8A-SafeASIL ?
• Design your safety-criti cal
system using a cost sensitive
STM8A microcontroller, with the
help of documentation supporting
their use in applications that
need to fulll functional safety
requirements as dened by
automotive safety integrity level
ASIL B of ISO 26262
• Develop your own self-test
library with the free-of-charge
safety manuals and the detailed
specication

ISO 26262 provides a standard about functional safety management
for automotive applications and includes an Automotive Safety
Integrity Level (ASIL) classication representative to automotive
application safety risk management requirement. Compliance to the
ISO 26262 standard has become a must in automotive applications.
ST offers STM8A-SafeASIL, a exible design support package
that stream lines certication of safety-critical systems featuring
STM8AF and STM8AL microcontrollers.
