Product details

That means it is not recommended for new production builds, though existing designs may still be supported through the end-of-life transition.

Automotive-grade 8-bit MCU with CAN and LIN

On-chip peripherals include a CAN 2.0B controller, LIN/UART, I²C, and a 6-channel 10-bit ADC.

Memory and peripheral fit

The 24 MHz core delivers enough throughput for a CAN node running a 1 ms control loop with margin.

Supply range and power rails

That flexibility simplifies the power tree — a single 5 V battery-backed rail or a 3.3 V regulated rail both work without a level shifter on the MCU side.

Frequently asked questions

Is STM8AF5286UDX obsolete or NRND?

It is not yet fully discontinued, but the manufacturer advises against using it in new production. Existing designs should plan a migration to a current-production STM8A variant.

Does STM8AF5286UDX have CAN and LIN interfaces?

Yes, the STM8AF5286UDX includes both a CAN 2.0B controller and a LIN/UART interface, along with I²C and a second UART. This makes it well-suited for automotive body networks where CAN and LIN are the standard buses.
