STMicroelectronics, Inc. Microcontrollers STM32L073RZT6U

The STM32L073RZT6U is an ultra-low-power 32-bit microcontroller based on the Arm Cortex-M0+ core, featuring a maximum clock speed of 32 MHz. It includes up to 192 KB of Flash memory, 20 KB of SRAM, and 6 KB of EEPROM. The device operates within a voltage range of 1.65 V to 3.6 V and supports a wide temperature range from -40 ¬8C to 125 ¬8C. This microcontroller is equipped with a rich set of peripherals, including a 12-bit ADC capable of sampling at 1.14 Msps across up to 16 channels, dual 12-bit DACs, and multiple communication interfaces such as USB 2.0, USART, SPI, and I2C. It also supports up to 24 capacitive sensing channels for touch applications and features a 7-channel DMA controller. The STM32L073RZT6U is designed for low power consumption, with a standby current of just 0.29 ¬µA and a wakeup time of 5 ¬µs from Flash memory. It includes various timers, a real-time clock, and advanced power management features, making it suitable for battery-operated devices and applications requiring energy efficiency. The device is available in multiple package options, including LQFP and WLCSP formats.
