Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. introduces a high-performance microcontroller STM32L431VCI6 Ultra-low-power 80 Mhz Arm Cortex-M4 MCU with FPU, featuring 256-KB Flash memory.

Description

The STM32L431VCI6 is a 32-bit MCU microcontroller with ultra-low power consumption based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at up to 80 MHz. The Cortex-M4 core has a single-precision floating-point unit (FPU) that supports all Arm® single-precision data processing instructions and data types. It also implements a full set of DSP instructions and a Memory Protection Unit (MPU) for increased application security.
