The NuMicro M2L31 microcontroller series is a remarkable innovation in the world of embedded systems, offering a perfect balance between performance and power efficiency. Designed with a focus on low power consumption, these microcontrollers boast a maximum clock frequency of 72MHz, making them ideal for a wide range of applications.
Featuring an Arm Cortex-M23 core, the M2L31 series comes in various configurations, offering between 64 to 512kbytes of non-volatile ReRAM and 40 to 168kbytes of SRAM. This series stands out with its support for two CAN FD and two USB Type-C PD 3.0 ports, providing ample connectivity options for diverse projects.
Targeted towards applications such as battery management, industrial automation, and consumer peripheral devices, the M2L31 series is equipped with three distinct low-power modes: normal shutdown, standby shutdown, and deep shutdown. This versatility allows developers to optimize power consumption based on specific requirements.
One of the standout features of the M2L31 microcontroller is its impressive power efficiency. In normal mode, the typical operating current is 60microamps/MHz, which significantly drops to a mere 500nanoamps in deep shutdown mode. This level of efficiency is made possible by the innovative ReRAM technology, developed in collaboration with TSMC, which eliminates the need for the time-consuming 'erase-before-write' process associated with traditional flash memory.
Moreover, the M2L31 series offers extensive support for a wide range of I/O and peripherals, including UART, I2C, SPI/I2S, and multiple USB options. Additionally, it provides compatibility with up to 16 channels of capacitive touch, enhancing the versatility and usability of the microcontroller in various applications.
