The 32 MHz Cortex-M0+ core delivers enough throughput for real-time control loops and protocol handling without burning the power budget of a faster core. The 192 KB Flash is sized for moderate firmware stacks — think sensor fusion algorithms or Modbus RTU slaves — but not for full GUI or heavy file-system workloads. ## Package and integration note Housed in a 100-UFBGA (7x7 mm) package, this is a fine-pitch BGA. The surface-mount footprint saves board area compared to an LQFP, but prototype rework is difficult. The lifecycle data carries conflicting signals: one entry flags end-of-life hot (EOL hot), while another lists the product status as Active. This is a red flag for any BOM freeze. We recommend treating this part as at-risk for obsolescence and securing a last-time-buy window if your design depends on it. The base product number is STM32L072, and ST typically offers pin-compatible density variants in the same family — a migration path to a higher-Flash sibling may be worth evaluating before committing production volumes.","metaTitle":"ST STM32L072VZI6 ARM Cortex-M0+ MCU, 32 MHz, 192 KB Flash","metaDescription":"STM32L072VZI6 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 192 KB Flash, 20 KB RAM, 3 KB EEPROM, 84 I/O, 100-UFBGA, -40 to 85°C.
