STM32L072CZT6
Overview
The STM32L072CZT6 is an ultra-low-power 32-bit microcontroller based on the Arm Cortex-M0+ core, operating at frequencies up to 32MHz. It features 192KB of Flash memory and a crystal-less USB 2.0 interface, making it an efficient choice for battery-operated devices requiring connectivity without external clock components.
Why Choose This Part
This MCU offers a high memory-to-power ratio with 192KB Flash and 20KB RAM while maintaining extremely low standby currents. The inclusion of 6KB of true data EEPROM and a crystal-less USB controller simplifies hardware design and reduces external component count.
