Automotive 8-bit MCU for body-control and sensor nodes
This combination targets dedicated control loops in body electronics, sensor fusion, and actuator management where extended temperature range and automotive qualification are mandatory.
NRND status — plan your BOM transition
This means STMicroelectronics will continue to manufacture the part for existing production programs but advises against starting new designs with this order code. For a BOM line already qualified, the NRND flag signals that a last-time-buy window may open — the exact timing depends on ST's PCN schedule.
Memory and peripheral budget
With 16 KB of Flash and 2 KB of RAM, this part fits firmware footprints for dedicated control loops — LIN slave nodes, window-lift controllers, or seat-position modules — but will be tight for a full CANopen stack or over-the-air update staging. The 512-byte EEPROM block is useful for calibration constants and fault-log storage without external memory. The 10-channel 10-bit ADC covers analog sensor inputs like temperature, position, or current sense, while the LIN and UART interfaces handle the typical automotive serial bus requirements.
Housed in a 48-LQFP package, the STM8AF6248TDX is a surface-mount device. The 38 I/O lines are accessible on the perimeter, making PCB routing straightforward for a two-layer board.
