The 1 KB EEPROM is useful for calibration constants or configuration parameters that need byte-level writes. ## Peripherals and connectivity On-chip peripherals include a brown-out detect/reset, DMA, POR, PWM, and watchdog timer. The 10-channel 12-bit ADC handles analog sensor inputs directly, reducing external component count. ## Package and footprint Housed in a 48-LQFP package (7x7 mm body), it offers 38 I/O lines. The LQFP footprint is widely supported in PCB tools and rework-friendly with a standard hot-air station. ## Lifecycle status — active and available The product status is listed as Active. This part is suitable for both prototyping and volume production without obsolescence risk in the near term.","metaTitle":"STM32L031C6T6 STMicroelectronics ARM Cortex-M0+ MCU, 32 MHz","metaDescription":"STM32L031C6T6 32-bit MCU with 32 KB Flash, 8 KB SRAM, 1 KB EEPROM, 32 MHz clock, 1.8V-3.6V supply, -40°C to 85°C, 48-LQFP.
