Shenzhen Meiyuxin Technology Co., Ltd. [Specialized in ST products] sells STM32G474VET6 ARM microcontroller - MCU Mainstream Arm Cortex-M4 MCU 170 MHz 512 Kbytes Quality assurance! ! !

Product Description:

The STM32G474VET6 devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at frequencies up to 170 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU) that supports all Arm single-precision data processing instructions and all data types. It also implements a full set of DSP (Digital Signal Processing) instructions and a Memory Protection Unit (MPU) for enhanced application security.

STM32G474VET6 These devices embed high-speed memory (up to 512 KB Flash, and 128 KB SRAM), a Flexible External Memory Controller (FSMC) for static memory (for devices with packages of 100 pins and more ), a Quad-SPI flash interface, and a wide range of enhanced I/O and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.

The STM32G474VET6 device also embeds several protection mechanisms for embedded flash and SRAM: read protection, write protection, secure memory area and proprietary code read protection. These devices embed peripherals that allow acceleration of math/arithmetic functions (CORDIC for trigonometric functions and FMAC unit for filter functions). They provide five fast 12-bit ADCs (4 Msps), seven comparators, six operational amplifiers, seven DAC channels (3 external and 4 internal), an internal voltage reference buffer, a low power RTC, two general-purpose 32-bit timers, three 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and one 16-bit low-power timer, and high resolution with 184 ps resolution rate timer.

STM32G474VET6 They also have standard and advanced communication interfaces such as:

- Four I2C

- Four SPIs multiplexed with two half-duplex I2S

- Three USARTs, two UARTs and one low-power UART.

- Three FDCANs

- one SAI

- USB device

STM32G474VET6 The device operates from a 1.71 to 3.6 V supply over the -40 to +85 °C (+105 °C junction) and -40 to +125 °C (+130 °C junction) temperature ranges. A comprehensive set of power saving modes allows the design of low power applications. Several independent supplies are supported, including inputs for analog independent supplies ADCs, DACs, operational amplifiers, and comparators. VBAT input allows backup of RTC and registers. The STM32G474xB/xC/xE series is available in 9 packages ranging from 48-pin to 128-pin.
