For existing production, secure last-time-buy quantities through independent distribution while supply lasts. For new designs, ST's current STM8A portfolio offers pin-compatible alternatives — qualify the alternate now to avoid a sole-source gap.
Surface-mount only. The tray shipping medium is standard for this package variant.
Existing production should plan for a last-time buy or qualify a pin-compatible alternate from the STM8A family.
Yes, the STM8AF5286UCY includes CAN, I2C, LIN, and UART/USART connectivity, making it suitable for automotive body and gateway nodes.
