Product details

STM8AF6288TCX — automotive 8-bit MCU with 24MHz core and AEC-Q100 grade

It runs at 24MHz from an internal oscillator, with 64KB of Flash program memory, 6K x 8 of RAM, and 2K x 8 of EEPROM for data storage.

For a BOM line already qualified, the NRND tag means you have time to secure last-time-buy quantities or identify a migration path. For new automotive designs, a pin-compatible alternative within the STM8A family should be evaluated before committing the layout.

24MHz core, 64KB Flash — sizing the firmware budget

The 24MHz clock rate is typical for an 8-bit MCU handling real-time control loops — LIN bus messaging, PWM generation for lighting or small motor drives, and sensor polling via the 10-bit ADC. The 64KB Flash provides room for a modest application stack plus bootloader; the 2K x 8 EEPROM holds calibration and configuration data across power cycles without needing external storage.

48-LQFP footprint and supply range

Frequently asked questions

What is the replacement for STM8AF6288TCX?

An official direct-replacement order code from STMicroelectronics is not listed in the available records. For new designs, evaluate other pin-compatible members of the STM8A family with the same 48-LQFP footprint. Contact your ST representative or distributor for the recommended migration path.

Can STM8AF6288TCX be used in new automotive designs?

Technically yes — the part is still available and fully qualified (AEC-Q100, -40°C to 125°C). However, because it carries NRND status, STMicroelectronics advises against using it in new designs. A future EOL notice could force a last-time-buy or a redesign, so a current-production STM8A variant is the safer choice for a new BOM.

What is the listed speed (24MHz) on this MCU?

The STM8AF6288TCX runs at 24MHz from its internal oscillator, which is the maximum core clock speed for this device. This is sufficient for typical automotive control tasks like LIN messaging, PWM generation, and ADC sampling at the 10-bit resolution.
