64 MHz Cortex-M0+ — enough for most real-time loops without a cache
The STM32G0B1CET6N is an STMicroelectronics 32-bit MCU built around an ARM Cortex-M0+ core clocked at 64 MHz.
Peripherals that save board space
This part integrates a 15-channel 12-bit SAR ADC and two 12-bit DACs, so analog sensor inputs and control outputs don't need external converters. The 42 GPIOs in the 48-LQFP package give enough pins for a keypad, a small display, and a few external peripherals without needing a port expander.
For a BOM line going into a new design, this removes the sourcing uncertainty that comes with NRND or obsolete parts. If you are planning a multi-year production run, this MCU is a safe choice for the firmware and PCB investment.
48-LQFP — hand-solderable with care
It is reworkable with a hot-air station and a fine-tip iron if you have steady hands and a good flux.
