The maximum clock frequency of the STM32NM50N is 72 MHz.
The STM32NM50N has 128 KB of flash memory.
No, the STM32NM50N is a 3.3V device and should not be operated at 5V.
No, the STM32NM50N does not have a built-in USB interface. However, it can be implemented using the device's GPIO pins and a USB transceiver.
The power consumption of the STM32NM50N depends on the operating mode and frequency. In low-power mode, the current consumption is around 2.5 mA/MHz, and in sleep mode, it is around 2.5 μA.
