STM32L071CZT6TR

STM32L071CZT6TR is an ultra‑low‑power 32‑bit MCU from ST’s STM32L0 family. It uses an ARM Cortex‑M0+ core running up to about 32 MHz and is designed for battery‑powered and energy‑efficient devices. Key specs (typical for this part): 128 KB of flash and 16 KB of RAM (in the CZT6 variant), wide operating voltage (about 1.65–3.6 V), and multiple low‑power modes (sleep, stop, standby) for extended battery life.
Peripherals commonly included: USB Full‑Speed device interface, USART/UART, I2C, SPI, 12‑bit ADC, DAC (where available), multiple timers, RTC, and an LCD controller for simple displays. Security/utility features such as CRC, DMA, and a bootloader are supported, and the device integrates with ST development tooling (STM32CubeMX, HAL/LL libraries) for easier software development. Debug/Programming is via ST‑Link or compatible debuggers.
Typical applications: battery-powered sensors and wearables, USB peripherals, portable IoT nodes, and basic medical/fitness devices. Packaging options around CZT6 offer a 64‑pin class LQFP/LQFP‑like footprint.
