Description

The STM32G0B1xB/xC/xE mainstream microcontrollers are based on high-performance Arm Cortex-M0+ 32-bit RISC core operating at up to 64

MHz frequency. Offering a high level of integration, they are suitable for a wide range of applications in consumer, industrial and appliance domains

and ready for the Internet of Things (IoT) solutions.

The devices incorporate a memory protection unit (MPU), high-speed embedded memories (144 Kbytes of SRAM and up to 512 Kbytes of flash program

memory with read protection, write protection, proprietary code protection, and securable area), DMA, an extensive range of system functions, enhanced

I/Os, and peripherals. The devices offer standard communication interfaces (three I2Cs, three SPIs / two I2S, one HDMI CEC, one full-speed USB, two FD

CANs, and six USARTs), one 12-bit ADC (2.5 MSps) with up to 19 channels, one 12-bit DAC with two channels, three fast comparators, an internal voltage

reference buffer, a low-power RTC, an advanced control PWM timer running at up to double the CPU frequency, six general-purpose 16-bit timers with one

running at up to double the CPU frequency, a 32-bit general-purpose timer, two basic timers, two low-power 16-bit timers, two watchdog timers, and a SysTick

timer. The devices provide a fully integrated USB Type-C Power Delivery controller.

The devices operate within ambient temperatures from -40 to 125°C and with supply voltages from 1.7 V to 3.6 V. Optimized dynamic consumption combined

with a comprehensive set of power-saving modes, low-power timers and low-power UART, allows the design of low-power applications.

VBAT direct battery input allows keeping RTC and backup registers powered.

The devices come in packages with 32 to 100 pins. Some packages with low pin count are available in two pinouts, standard and alternative. The devices with

the alternative pinout, marked with N suffix, offer the VDDIO2 supply and an additional UCPD port. They are the best choice for UCPD/USB applications.
