Product details

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.

Frequently asked questions

What is the equivalent for STM32L072CZT6?

A functional peer is the STM32L151CBU6A, which moves to a Cortex-M3 core at the same 32 MHz and offers a similar peripheral set including USB, I²C, SPI, and UART, plus 16-channel 12-bit ADC. The STM32L151 series draws slightly more active current due to the M3 core, so the L072 remains the better choice for ultra-low-power battery applications.
