This device is housed in a TSSOP-20 (4.4x6.5mm) package and operates across a -40\u00b0C ~ +105\u00b0C. It supports a supply voltage range of 2.4V ~ 5.5V. The component meets industry standards for reliability and is suitable for demanding applications.","working_principle":"The microcontroller integrates a processor core with on-chip Flash memory, SRAM, and peripheral modules. The CPU fetches instructions from Flash, executes them using the pipelined architecture, and communicates with peripherals through the internal bus. Multiple power management modes allow flexible trade-offs between performance and consumption. On-chip oscillators eliminate the need for external clock components.","pin_description":"
