Working Principle

NUCLEO-L073RZ microcontroller evaluation board is based on ARM Cortex-M0+ core processor STM32L073RZT6 from STMicroelectronics. It is a small and low-cost evaluation board with a wide range of integrated peripherals. NUCLEO-L073RZ is provided with four communication interfaces: ST-Link/V2, USB, USART, and I2C. NUCLEO-L073RZ microcontroller board provides users with 8KiB of SRAM, 256 KiB of flash memory, and two analog-to-digital converters. The board also has an optional user LED and a user button. The board requires an external power supply for operation. It can operate with either a 5V DC adapter or USB connector.

The STM32L073RZT6 microcontroller includes Cortex-M0+ core processor with 32 KiB of flash memory. Furthermore, the microcontroller includes Up to 16 KiB of SRAM memory and four independent I/Os (two of which are exclusive for each serial communication interface). The board also includes a user LED and an optional user button.

The actual operating voltage of the microcontroller and the I/O pins depends on the voltage applied to its VDD supply. When the VDD pin is supplied with 5V, the operating voltage of 3.3V is used for most of the components, including I/O pins. NUCLEO-L073RZ uses an oscillator to source a clock signal. This oscillator can be either an external clock signal or an integrated crystal oscillator.
