| 1 | +# STM32G431-Nucleo BSP Introduction |
| 2 | + |
| 3 | +[中文](README_zh.md) |
| 4 | + |
| 5 | +## MCU: STM32G431RB @170MHz, 128KB FLASH, 32KB RAM |
| 6 | + |
| 7 | +The STM32G431x6/x8/xB devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 170 MHz. |
| 8 | + |
| 9 | +The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security. |
| 10 | +These devices embed high-speed memories (128 Kbytes of Flash memory, and 32 Kbytes of SRAM), an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix. |
| 11 | +The devices also embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, securable memory area and proprietary code readout protection. |
| 12 | +The devices embed peripherals allowing mathematical/arithmetic function acceleration (CORDIC for trigonometric functions and FMAC unit for filter functions). |
| 13 | +They offer two fast 12-bit ADCs (5 Msps), four comparators, three operational amplifiers, four DAC channels (2 external and 2 internal), an internal voltage reference buffer, a low-power RTC, one general-purpose 32-bit timers, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer. |
| 14 | +They also feature standard and advanced communication interfaces such as: |
| 15 | +\- Three I2Cs |
| 16 | +\- Three SPIs multiplexed with two half duplex I2Ss |
| 17 | +\- Three USARTs, one UART and one low-power UART. |
| 18 | +\- One FDCAN |
| 19 | +\- One SAI |
| 20 | +\- USB device |
| 21 | +\- UCPD |
| 22 | +The devices operate in the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges from a 1.71 to 3.6 V power supply. A comprehensive set of power-saving modes allows the design of low-power applications. |
| 23 | +Some independent power supplies are supported including an analog independent supply input for ADC, DAC, OPAMPs and comparators. A VBAT input allows backup of the RTC and the registers. |
| 24 | +The STM32G431x6/x8/xB family offers 9 packages from 32-pin to 100-pin. |
