STM32L072CBY6TR

STM32L072CBY6TR is an ultra‑low‑power MCU from STMicroelectronics’ STM32L0 family. It uses a 32‑bit ARM Cortex‑M0+ core and runs up to about 32 MHz. Memory size (Flash/RAM) and exact peripherals depend on the specific package/variant, but the L072 line generally provides a solid balance of performance and power efficiency for battery‑powered designs.
Key features (typical for the L072 family):
- USB Full‑Speed device capability
- 12‑bit ADC, and often a DAC
- LCD controller in supported packages
- RTC, multiple timers, I2C/SPI/UART peripherals
- Low‑power modes (various sleep/stop/standby) with long battery life
- Optional hardware features such as op‑amps/comparators
Packaging note: CBY6TR indicates a specific device variant in a Tape & Reel package (suffix TR) and is associated with a 48‑pin style package in the L072 subfamily.
Common use cases: wearables, sensors, portable meters, and other energy‑constrained embedded systems. Development is supported by STM32CubeMX/HAL/LL libraries and ST’s development tools. For exact memory sizes and peripherals, refer to the datasheet for the CBY6 variant.
