STM32G0B1RBT6 Microcontroller
The STM32G0B1RBT6 is a 32-bit ARM Cortex-M0+ microcontroller from STMicroelectronics, designed for cost-sensitive, high-efficiency embedded applications. Operating at up to 64 MHz, it integrates a single-cycle multiplier and a hardware divider, enabling rapid arithmetic operations. The Cortex-M0+ core features a 2-stage pipeline, low power consumption (9 µA in Stop mode), and a Nested Vectored Interrupt Controller (NVIC) for deterministic interrupt handling. With 128 KB of flash memory and 36 KB of SRAM, it supports In-System Programming (ISP) via USART/I²C and In-Application Programming (IAP), facilitating firmware updates. Its voltage range (1.7 V–3.6 V) and extended temperature range (-40°C to +125°C) make it suitable for industrial and automotive applications.
The STM32G0B1RBT6 offers a rich set of peripherals, including two I²C interfaces, three USARTs, one SPI port, and one CAN FD interface, enabling flexible communication with sensors, displays, and automotive networks. It features a 12-bit ADC with 16 channels, a 16-bit timer with PWM outputs, and a low-power timer (LPTIM) for energy-efficient scheduling. The device includes 34 general-purpose I/O pins (configurable via GPIO matrix) and supports hardware CRC calculation for data integrity. Additional features like a watchdog timer (WDT), brown-out reset (BOR), and unique device ID enhance system reliability. The integrated CAN FD controller supports high-speed automotive communication (up to 5 Mbps).
