Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. (Supply, Recycle) ST Microcontroller STM32L452REY6TR Ultra Low Power Arm® Cortex®-M4 32-bit MCU + FPU, 100DMIPS, up to 512KB Flash, 160KB SRAM, Analog, Audio, Peripherals.

STM32L452REY6TR Product Overview:

The STM32L452xx devices are ultra-low power microcontrollers based on the high-performance Arm® Cortex®-M4 32-bit RISC core, operating at up to 80 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU) and 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 enhanced application security.

The STM32L452xx device embeds high-speed memory (up to 512K bytes of Flash, 160K bytes of SRAM), a quad SPI Flash interface (available on all packages) and a large number of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.

The STM32L452xx devices embed multiple protection mechanisms for embedded Flash and SRAM: read protection, write protection, proprietary code read protection and a firewall.
