Low-power Cortex-M0+ MCU with integrated USB and analog
It packs 192 KB of Flash program memory, 20 KB of SRAM, and a dedicated 6 KB EEPROM block for data storage without external EEPROM. The device integrates a 12-bit ADC with 10 channels and two 12-bit DACs, plus USB 2.0, I²C, SPI, and multiple UART/USART interfaces.
Memory and peripheral headroom for sensor-node designs
The 192 KB Flash and 20 KB SRAM provide enough code and data space for moderate-complexity firmware, such as sensor fusion algorithms or USB CDC/ HID stacks. The 6 KB EEPROM, rated for high endurance, allows storing calibration constants, device configuration, or logging data without wearing the Flash.
ROHS3 compliant. For production planning, the active status means no last-time-buy pressure and continued manufacturer support through the STM32L0 roadmap.
