Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Description:

The STM32U545VEI6 is an advanced energy efficient microcontroller based on Arm® Cortex-M33 to meet the most demanding power/performance requirements for smart applications, including wearables, HMI, personal medical devices, home automation and industrial sensors.

The STM32U5 series microcontrollers integrate up to 4 MB of Flash memory (dual sectors) and 3 MB of SRAM on chip, with advanced graphics processing capabilities that take performance to the next level.

The STM32U5 series offers greater integration and storage capacity to maximize performance. The series is the first 32-bit ultra-low-power MCU to integrate up to 4 MB of Flash memory.

Low power consumption:

Energy benchmark:

535 ULPMark-CP

149 ULPMark-PP

133000 SecureMark-TLS

LPBAM (Low Power Background Autonomous Mode) is an innovative autonomous power mode that reduces power consumption by enabling direct memory access (LPDMA Low Power Direct Memory Access) and ensuring peripherals remain operational while most devices are in stop mode.

Embedded SMPS (Switched Mode Power Supply) Buck Converter (optional)

Key performance indicators include:

In off mode, the value is 110nA

In standby mode, the value is 300nA

Stop mode 3 1.7µA, 16Kb SRAM

6.6µA, 786Kb SRAM in Stop mode 2

As low as 19µA/MHz in active mode
