Instructions for Use:

1. Power Supply Requirements:

   • Ensure the operating voltage (VDD) is within the specified range of 1.71V to 3.6V.
   • Connect the power supply lines to the appropriate VDD and GND pins.

2. Clock Configuration:

   • Configure the internal or external clock sources as per your application requirements.
   • Adjust the PLL settings if needed to achieve desired CPU frequency up to 80 MHz.

3. Low Power Mode Management:

   • Implement sleep, stop, or standby modes in your firmware to optimize power consumption based on operational needs.

4. Peripheral Initialization:

   • Initialize communication interfaces like I2C, SPI, USART, etc., according to the data rates and protocols required by connected devices.
   • Set up analog peripherals such as ADCs and DACs for signal processing tasks.

5. GPIO Configuration:

   • Configure GPIO pins as inputs, outputs, or alternate functions as necessary for interfacing with other components.

6. Security Features:

   • Utilize the AES hardware accelerator for secure data encryption and decryption operations.

7. Programming and Debugging:

   • Use an ST-LINK programmer/debugger to load code onto the microcontroller and debug applications.
   • Refer to the STM32CubeMX tool for initial configuration and HAL library setup.

8. Consult Datasheet and Reference Manual:

   • For detailed pin configurations, electrical characteristics, and programming specifics, always refer to the official STM32L432KBU6TR datasheet and reference manual provided by STMicroelectronics.
