Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., Ltd. has been consistently supplying STMicroelectronics' STM32L452REY6TR microcontroller: an ultra-low-power Cortex-M4 microcontroller with an integrated FPU and USB/DFSDM.

Product Overview  

STMicroelectronics STM32L452REY6TR — an ultra-low-power microcontroller (MCU) based on the ARM® Cortex®-M4 core, operating at up to 80MHz, with an integrated single-precision floating-point unit (FPU) and support for DSP instruction sets, suitable for high-performance embedded systems. The chip is packaged in a 64-WLCSP (3.36×3.66mm) package, featuring 512KB of flash memory and 160KB of SRAM, along with a USB full-speed device interface and a digital filter Sigma-Delta modulator (DFSDM). It is widely used in IoT, industrial control, medical devices, and smart home applications.

Key Features

1. High-performance Cortex-M4 core with ultra-low power design

80MHz ARM Cortex-M4, supporting DSP instruction set and FPU floating-point operations, suitable for complex algorithms (e.g., motor control, digital signal processing).

Ultra-low power consumption mode: operating mode as low as 100µA/MHz, standby mode only 1.7µA (with SRAM retained), shutdown mode as low as 30nA, suitable for battery-powered devices.  

Dynamic voltage regulation (DVM): optimises power consumption under different loads to extend battery life.

2. Rich peripheral interfaces  

USB 2.0 full-speed device interface (supports OTG), suitable for data communication and firmware updates.  

Digital filter Sigma-Delta modulator (DFSDM): supports external Σ-Δ ADC or PDM microphones, suitable for high-precision audio and sensor data acquisition.  

Multi-channel communication interfaces:  

CAN 2.0B (industrial control)  

I²C/SPI/UART (sensor connection)  

QSPI (external flash memory)  

SAI (audio interface)  

3. High-integration storage and security features  

512KB flash memory (supports ECC) + 160KB SRAM, meeting complex firmware requirements.  

Memory protection unit (MPU): enhances code security and prevents unauthorised access.  

AES-256 hardware encryption (supported on some models), suitable for security-critical applications.

4. Wide Voltage Range and Industrial-Grade Reliability

1.71V to 3.6V power supply, suitable for battery or low-power power supply designs.

Operating temperature: -40°C to 85°C (industrial-grade), with some models supporting high-temperature environments up to 105°C.
