STM32L073RZT6TR

STM32L073RZT6TR is an STM32L0 ultra‑low‑power microcontroller from STMicroelectronics. It uses an ARM Cortex‑M0+ core and runs up to 48 MHz, targeting battery-powered and energy‑efficient applications. Memory varies by package, but devices in this family typically offer up to about 128 KB Flash and around 16 KB SRAM. Peripherals include USB Full‑Speed device, LCD controller for segmented LCDs, 12‑bit ADC, 12‑bit DAC, multiple serial interfaces (USART/UART, I2C, SPI), timers and DMA, plus RTC. It supports multiple low‑power modes (Sleep/Stop/Standby) with fast wake‑up for long battery life. The RZT6TR suffix indicates a 48‑pin LQFP package in Tape & Reel industrial packaging. Development is supported by ST’s STM32CubeMX/CubeIDE with HAL/LL libraries, and programming options include SWD/JTAG or USB DFU depending on package. Ideal for wearables, sensors, and compact IoT devices. For exact memory sizes, peripherals, and operating conditions, consult the official datasheet and reference manual.
