Product details

Automotive 8-bit MCU for the 150°C engine bay

The STM8AF62A6UDY: Seven 10-bit ADC channels, I²C, LIN, SPI, and UART/USART interfaces cover the typical sensor-and-actuator bus set for automotive sub-systems.

NRND — last-time-buy window is the procurement timeline

That means the part is still available for ongoing production through the independent channel, but the clock is running—no new BOM starts should land here. For an existing line using the STM8AF62A6UDY, the immediate sourcing move is to secure enough inventory for the remaining build window.

5x5 mm 32-VFQFPN — thermal pad and footprint

The 32-VFQFPN (5x5 mm) exposed-pad package is the same footprint used across the STM8A 32-pin QFN variants. No pinout detail is reproduced here; the official ST datasheet is the binding reference for signal assignments.

Supply range and on-chip peripherals

Runs on 3V to 5.5V supply, which directly suits automotive battery-rail environments without an external regulator in many cases.

Frequently asked questions

What is the product status of STM8AF62A6UDY?

It is NRND (Not Recommended for New Designs), so engineers and buyers must evaluate alternatives to avoid future obsolescence.

What is the direct replacement or equivalent for STM8AF62A6UDY?

Customers needing long-term supply must find a pin-compatible or drop-in alternative to sustain production or repairs.

Where can I buy STM8AF62A6UDY and check stock?

Sourcing buyers need current distributor availability and lead times to avoid production delays.

What is the current price of STM8AF62A6UDY?

Price influences BOM cost and sourcing decisions, especially when considering alternatives.

What is the package and pinout of STM8AF62A6UDY?

Designers must verify footprint compatibility for PCB layout and replacement compatibility.

Is STM8AF62A6UDY pin compatible with other STM8A microcontrollers?

Engineers looking for a quick drop-in replacement need to know if the pinout matches other parts in the series.
