Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. supplies [ST microcontroller] ultra-low power microcontroller STM32L431CCT6 based on high-performance ARM®Cortex®-M4 32-bit RISC core, operating frequency up to 80MHz.

Description:

The STM32L431CCT6 microcontroller is based on a new ultra-low power platform with FlexPowerControl. It increases the flexibility to achieve optimised power consumption. the STM32L4 outperforms its market counterparts in the area of ultra-low power consumption with an EEMBC ULPBench score of 150 ULPBench™-CP.

It offers up to 2Mbyte of Flash (dual banks) and up to 640Kbytes of SRAM, and can deliver 100DMIPS/273 CoreMark scores thanks to the 80MHz ST ART Accelerator™. The multi-AHB bus matrix and DMA controller optimise the overall system performance.

The STM32L431CCT6 microcontroller can be used to replace current designs using the STM32F4 for low-power functionality. It has pin-to-pin compatibility and can replace the STM32F4 without changing the board layout.
