Active lifecycle and automotive qualification
The STM8AF6266UCY: This is a standard-production part, not a last-time-buy or NRND item — no supply discontinuity to plan around. It is qualified to AEC-Q100, the automotive stress-test qualification standard. That covers the full suite of reliability tests — HTOL, ESD, latch-up, temperature cycling — required for Tier-1 automotive ECUs and chassis-domain modules.
Core architecture and memory sizing
The EEPROM is separate from the Flash — useful for calibration constants or fault logs that need byte-level erase without wearing the program sector. The 32 KB Flash is typical for body-control and sensor-fusion tasks: enough for a LIN stack plus application code, but not sized for over-the-air image staging (that would want external serial Flash).
Supply voltage and peripheral set
Supply range is 3V to 5.5V, which covers a 12V battery system through a 5V regulator and also runs directly from a 3.3V rail. The on-chip peripherals include I²C, LINbus, SPI, and UART/USART — the LIN controller is the key one for automotive sub-bus communication.
Supplied in a VFQFN with exposed pad, surface-mount.
