Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Product Introduction:

The STM32G474VCH3 is a 170 MHz mainstream ARM Cortex-M4 MCU with DSP and FPU featuring 256 KB of Flash memory, math accelerator, high-resolution timers, and high analog level integration.

The Cortex-M4 kernel comes with a single-precision floating-point unit (FPU) that supports all Arm single-precision data processing instructions and all data types. The kernel also has a complete set of DSP (digital signal processing) instructions and a memory protection unit (MPU) for enhanced application security.
