Product details

16 MHz 8-bit core with automotive-grade peripherals

If you are qualifying this part for a new automotive ECU or module, the NRND flag is a hard stop — you need to evaluate a pin-compatible successor or a different STM8A variant before the design locks. For ongoing production, secure your volume requirements early; once the LTB window closes, the only channel will be independent distribution, where date-code provenance and pricing vary lot to lot.

Memory and peripheral sizing

16 KB of Flash and 2 KB of RAM. A typical LIN slave node or window-lift controller fits; a full CANopen stack with multiple PDO mappings will likely overflow.

Frequently asked questions

Is STM8AF6246TCSSSX obsolete or nearing end of life?

It is not yet fully obsolete, but STMicroelectronics has signaled that it will not support new designs with this part. Existing production runs can still source it, but a last-time-buy notice is expected. For new designs, evaluate a pin-compatible alternative within the STM8A family.
