It integrates 3 KB of on-chip EEPROM for parameter storage, avoiding an external serial EEPROM.
On-chip peripherals include a 10-channel 12-bit ADC, brown-out detect, POR, PWM, WDT, and DMA — enough for closed-loop control and data logging without external glue logic.
ST lists the STM32L071K8U3 as Active (current production) with ROHS3 compliance.
