The STM32F072VBH6: ARM Cortex-M0 32-bit MCU at 48 MHz with 128 KB Flash, 16 KB RAM, and 1.65-3.6 V supply. 100-UFBGA (7x7 mm) package with 87 I/O and connectivity including CAN, USB, I²C, SPI, UART, and HDMI-CEC.
Supply range and temperature — field-fit check
The 1.65 V minimum supply is the standout here: it lets the MCU stay alive during a battery discharge cycle or a 1.8 V logic rail brownout without a boost converter, which saves a component and a few millimetres of board space.
