STM8AL3146UCX: 8-bit MCU for automotive and industrial control
It runs at 16 MHz, with 16 KB of Flash program memory, 2K x 8 of RAM, and 1K x 8 of EEPROM for data storage.
NRND status — what it means for procurement
That means it remains available for existing production but is not intended for new design wins.
16 MHz core speed — real-time control headroom
The 16 MHz clock rate is the maximum for this STM8A core. For a typical motor-control or sensor-fusion loop running from Flash, expect instruction execution at roughly 16 MIPS. That is sufficient for LIN-bus node controllers, DC-brush motor drivers, or simple pump/fan regulation where deterministic timing matters more than raw throughput.
Package and footprint — 32-VFQFN with exposed pad
The 30 I/O pins include multiplexed ADC and DAC channels, so verify pin allocation against your sensor and actuator count early in layout.
