Product details

STM8AF6246ITCX — automotive 8-bit MCU with AEC-Q100 qualification

It operates from 3 V to 5.5 V supply and is rated for -40°C to 125°C ambient temperature, making it suitable for under-hood and harsh industrial environments.

NRND lifecycle — plan your BOM transition

This means STMicroelectronics will continue to support existing production for a limited window, but the part is on a path toward end-of-life. For new designs, a pin-compatible replacement within the STM8A family should be evaluated.

The 16 MHz core speed handles body-control tasks. The 16 KB Flash and 2 KB RAM limit firmware and buffer size.

The STM8AF6246ITCX is in a 32-lead LQFP package (7x7 mm body). The 25 I/O pins are on the perimeter.

The STM8AF6246ITCX is AEC-Q100 qualified.

Frequently asked questions

Is STM8AF6246ITCX obsolete?

The STM8AF6246ITCX is NRND (Not Recommended for New Designs), meaning it is not yet obsolete but is on a phase-out path. STMicroelectronics continues to support existing production for a limited period. For new designs, a replacement within the STM8A family should be selected.

What replacement for STM8AF6246ITCX?

A direct pin-compatible replacement within the STM8A family is the most practical option. STMicroelectronics recommends evaluating the STM8AF62xx series for a drop-in upgrade with similar or enhanced memory and peripheral options. Contact our team for specific cross-reference support.

What is the package of STM8AF6246ITCX?

The STM8AF6246ITCX is packaged in a 32-lead LQFP with a 7x7 mm body (0.8 mm pitch). The supplier device package is 32-LQFP (7x7).

Is STM8AF6246ITCX automotive qualified?

Yes, the STM8AF6246ITCX is AEC-Q100 qualified and belongs to the STM8A automotive series, making it suitable for automotive and harsh industrial environments.

What is the operating temperature of STM8AF6246ITCX?

The STM8AF6246ITCX is rated for -40°C to 125°C ambient temperature (TA), covering under-hood automotive and industrial high-temperature applications.
