CY8C21634-24LTXI datasheet by Cypress Semiconductor

CY8C21634-24LTXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The CY8C21634-24LTXI can operate from -40°C to +85°C, making it suitable for industrial and automotive applications.
• How do I configure the clock source for the microcontroller?
  The clock source can be configured using the Clock Divider (CLKDIV) register. You can choose from internal oscillator, external crystal oscillator, or external clock source. Refer to the Cypress documentation for specific register settings.
• What is the maximum current consumption of this microcontroller?
  The maximum current consumption of the CY8C21634-24LTXI is approximately 25mA at 24MHz, but this can vary depending on the operating frequency, voltage, and peripheral usage.
• Can I use the microcontroller's internal flash memory for data storage?
  Yes, the CY8C21634-24LTXI has 16KB of internal flash memory that can be used for data storage, in addition to the 4KB of SRAM. However, the flash memory is not suitable for frequent write operations, and you should use the EEPROM or external memory for such applications.
• How do I implement low-power modes on this microcontroller?
  The CY8C21634-24LTXI has several low-power modes, including Sleep, Hibernate, and Stop modes. You can configure these modes using the Power Mode (PM) register and the Sleep Timer (ST) register. Refer to the Cypress documentation for specific register settings and power-saving techniques.
