Product details

Automotive 8-bit MCU with integrated EEPROM and LIN

It runs at 16 MHz and packs 8 KB of Flash program memory, 1K x 8 RAM, and 640 x 8 EEPROM on-chip — enough for small control loops, LIN node firmware, or sensor fusion tasks in under-hood or chassis-domain modules.

Peripherals and connectivity for body electronics

All 28 I/O are available in the 32-LQFP package.

NRND — plan for last-time-buy or alternate

That means ST is winding down support — new projects should target a pin-compatible successor or a different STM8A variant.

Temperature grade and package rework

The 32-LQFP package is a 0.8 mm pitch quad flat pack — rework-friendly with a hot-air station, but the fine pitch demands careful alignment.

Frequently asked questions

Is STM8AF6226TASSSX obsolete?

It is not fully discontinued, so last-time-buy planning is advisable.

What is the replacement for STM8AF6226TASSSX?

For new designs, evaluate other STM8A family members with similar pinout and memory — the STM8A series offers multiple Flash and RAM options in the same 32-LQFP package.

Is STM8AF6226TASSSX AEC-Q100 qualified?

Yes, the STM8AF6226TASSSX is part of the Automotive, AEC-Q100 series, making it qualified for automotive-grade applications.

What are the specifications of STM8AF6226TASSSX?

The STM8AF6226TASSSX is an 8-bit MCU with a 16 MHz core, 8 KB Flash, 1K x 8 RAM, 640 x 8 EEPROM, 7-channel 10-bit ADC, and interfaces including I²C, LINbus, SPI, and UART/USART.
