Product details

16 MHz 8-bit core for automotive body control

The STMicroelectronics STM8AF6246UAY is an 8-bit microcontroller from the STM8A series, built around the STM8A core running at 16 MHz. The 25 available I/O lines and integrated peripherals (brown-out detect, POR, PWM, WDT) reduce external glue logic.

Connectivity and analog interface

The 7-channel 10-bit ADC lets the MCU read analog sensors (potentiometers, thermistors) without an external converter.

Supply range and operating temperature

Supply voltage spans 3 V to 5.5 V.

Lifecycle status: NRND

Frequently asked questions

Where can I buy STM8AF6246UAY and get a price?

The STM8AF6246UAY is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ through this listing.

What is the closest pin-compatible alternative to STM8AF6246UAY?

No official successor or pin-compatible alternative is listed in the lifecycle record. For a new design, consult the STM8A automotive-series product selector for a current part with similar Flash size and peripheral set.

What is STM8AF6246UAY's listed speed?

The core runs at 16 MHz, which sets the instruction cycle time for the 8-bit STM8A pipeline — adequate for LIN messaging and local control loops, not for high-speed DSP.

What series is STM8AF6246UAY part of?

It belongs to the STM8A series, STMicroelectronics' automotive-grade 8-bit microcontroller family.
