With 84 general-purpose I/Os and a 12-bit ADC (16 channels) plus a 12-bit DAC (2 channels), it covers sensor aggregation, human-machine interface, and low-power data logging roles. The 100-UFBGA package (7x7 mm body) is the smallest footprint for this I/O count, but it demands fine-pitch assembly and X-ray inspection; if your board shop isn't set up for 0.5 mm pitch BGA, the LQFP-100 variant (STM32L072VBT6) is a drop-in alternative on the same die. The base product number STM32L072 covers a family of Flash and RAM density options in the same package footprint, so if the 128 KB / 20 KB configuration is tight, a pin-compatible upgrade path exists within the series.","metaTitle":"STM32L072VBI6 ARM Cortex-M0+ MCU, 32 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32L072VBI6 32-bit MCU: ARM Cortex-M0+ at 32 MHz, 128 KB Flash, 20 KB RAM, 6 KB EEPROM, USB, 84 I/O, -40 to 85°C.
