Core advantages
The core value of STM32L496ZGT6 lies in the integration of ultra-low power consumption and high performance.At the 80MHz main frequency, the 273.55 CoreMark running score means that it can easily handle complex algorithm operations, and the operating power consumption of 91µA/MHz makes it capable of long-term battery-powered running tasks.It supports 7 major low-power modes and allows independent power supply for each peripheral to achieve refined energy consumption management.With the built-in SMPS (switch mode power supply), the operating power consumption can be further reduced to 37µA/MHz, greatly extending the battery life.
The 1MB dual bank flash memory supports simultaneous read and write operations (RWW), allowing the other bank to be erased and written while running code, facilitating on-site firmware upgrades and secure storage redundancy.The Chrom-ART hardware graphics accelerator effectively reduces the burden on the CPU. With LCD driver and capacitive touch, it performs particularly well in applications that require a graphical interface.STMicroelectronics’ STM32Cube ecosystem provides a complete HAL driver library, middleware and graphical configuration tools, significantly shortening the development cycle.
