The STM8AF6246UCY is an 8-bit microcontroller from the STM8A series, AEC-Q100 qualified, with a 16 MHz internal oscillator, 16 KB Flash, 2 KB RAM, and 512 bytes EEPROM.
16 MHz core, 16 KB Flash — sizing the firmware and timing budget
At 16 MHz the STM8 core executes most instructions in one or two clock cycles. The 16 KB Flash is field-reprogrammable; the 512-byte EEPROM is separate from Flash. Peripherals include I2C, LINbus, SPI, and UART/USART — the LIN interface is the typical choice for automotive body networks. The 7-channel 10-bit ADC handles analog inputs like temperature or position sensors.
NRND status — what it means for procurement
For a BOM line already qualified, the NRND flag isn't an immediate cut-off — but it does signal that a last-time-buy window or eventual EOL notice is on the horizon. For new designs, a pin-compatible alternative within the STM8A family should be evaluated. The NRND status applies to both tray and other packing options.
32-VFQFN package — layout and thermal notes
The part comes in a 32-VFQFN exposed-pad package, supplier device package 32-VFQFPN 5x5 mm. Surface-mount only.
