STM32G071R8T6 Description

The high-performance Arm? Cortex?-M0+ 32-bit RISC processor of the STM32G071R8T6 mainstream microcontrollers operates at up to 64 MHz frequency. They are appropriate for a wide range of applications in the consumer, industrial, and appliance domains and are prepared for the Internet of Things (IoT) solutions because of their high level of integration.

The devices include a memory protection unit (MPU), high-speed embedded memories, DMA, a wide range of system functions, improved I/Os, and peripherals (up to 128 Kbytes of Flash program memory with reading protection, write protection, proprietary code protection, and securable area, and 36 Kbytes of SRAM). The devices feature four USARTs, two I2Cs, two SPIs/one I2S, one HDMI CEC, one 12-bit ADC (2.5 MSPs) with up to 19 channels, two fast comparators, an internal voltage reference buffer, a low-power RTC, an advanced control PWM timer, five general-purpose 16-bit timers, one of which operates at up to twice the CPU frequency, a 32-bit general-purpose timer, two ba. A completely integrated USB Type-C Power Delivery controller is offered by the STM32G071x8/xB devices.

The gadgets function in temperatures between -40 and 125 °C. With supply voltages ranging from 1.7 V to 3.6 V, they can function. Low-power applications can be created thanks to optimized dynamic consumption, a wide range of power-saving settings, low-power timers, and low-power UART.

RTC and backup registers can be kept powered by VBAT direct battery input.

Packages for the devices range in size from 28 to 64 pins.
