Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The STM32L552MEY6 ultra-low power MCUs are designed for embedded applications that require high security and low power consumption. These MCUs are based on the Arm® Cortex®-M33 processor and its TrustZone® for Armv8-M in combination with ST security implementation.

These devices embed high speed memory (512KB of Flash and 256KB of SRAM), a flexible external memory controller (FSMC) for static memory (for devices with packages of 100 pins and above), an Octo-SPI Flash interface (available on all packages) and connections to two APB buses, two AHB buses and a 32-bit multi AHB bus matrix for a large number of enhanced I/Os and peripherals.
