Mingjiada Supplies the STM32L496VGY6PTR—Specializing in STMicroelectronics’ STM32L4 Series MCUs, Providing One-Stop Procurement Services for Ultra-Low-Power, High-Performance Embedded Solutions

I. Product Overview: Flagship Ultra-Low-Power MCU

Leveraging nearly three decades of experience in electronic component distribution and a global supply chain network, Shenzhen Mingjiada Electronics Co., Ltd. specializes in supplying the ST (STMicroelectronics) STM32L496VGY6PTR microcontroller. This device is a key member of the STM32L4 series’ ultra-low-power product line. Based on a high-performance Arm® Cortex®-M4 32-bit RISC core operating at up to 80 MHz, it integrates a single-precision FPU (floating-point unit) and a complete DSP instruction set, achieving an excellent balance between ultra-low power consumption and computational performance.

The STM32L496VGY6PTR is housed in a 100-pin WLCSP package (4.62 x 4.14 mm) and features 1 MB of Flash and 320 KB of SRAM. It supports a wide range of peripherals, including USB OTG, LCD drivers, DFSDM (digital filter sigma-delta modulator), and other rich peripherals. It is specifically designed for applications such as industrial control, smart IoT, medical devices, and wearables that demand both low power consumption and high performance.
