The 32 MHz Cortex-M0+ core delivers enough throughput for real-time control of brushless DC motors, sensor readout at several kHz, or Modbus RTU polling on the UART. The 128 KB Flash is the mid-density option in the STM32L0 value line — enough for a bootloader plus application code, but not overkill for a simple I/O expander. The 20K x 8 SRAM handles moderate data buffers; if your application needs larger packet queues, step up to the 48K x 8 variant in the same package. The integrated 6K x 8 EEPROM eliminates an external serial EEPROM for calibration constants or configuration parameters, saving board space and one I²C/SPI bus. The 1.65 V minimum supply means this MCU can stay alive on a battery down to near-depletion, critical for battery-powered edge nodes. The 25 I/O lines in the 32-pin package are adequate for a keypad matrix, a few LEDs, and a serial debug header. On-chip peripherals include a 10-channel 12-bit ADC, PWM timers, a watchdog timer, DMA, and brown-out/reset detection.","metaTitle":"ST STM32L071KBU6TR ARM Cortex-M0+ MCU, 32MHz, 128KB Flash","metaDescription":"STM32L071KBU6TR 32-bit MCU, ARM Cortex-M0+ at 32MHz, 128KB Flash, 20K x 8 RAM, 6K x 8 EEPROM, 1.65V-3.6V, -40°C to 85°C, 32-UFQFPN.
