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.","metaTitle":"ST STM8AL3146UCX 8-bit MCU, 16 MHz, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AL3146UCX 8-bit MCU, 16 MHz core, 16 KB Flash, 2K x 8 RAM, AEC-Q100, -40°C to 125°C.
