Product details

The STMicroelectronics STM32G0B1CCU6 is a 32-bit ARM Cortex-M0+ MCU from the STM32G0 series, clocked at 64 MHz with 256 KB Flash and 144 KB RAM. It packs 42 I/O and a connectivity set that includes CANbus, USB, I²C, SPI, and multiple UART/USART lines — enough for a compact industrial controller or an IoT edge node that needs to talk to a fieldbus and a host at the same time. The 48-UFQFN package with exposed pad keeps the footprint tight while giving the die a decent thermal path to the board.
