CY8C20636A-24LTXI datasheet by Cypress Semiconductor

CY8C20636A-24LTXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The CY8C20636A-24LTXI can operate from -40°C to +85°C.
• How do I configure the clock source for the microcontroller?
  The clock source can be configured using the Clock Control Register (CLK_CR). The internal main oscillator (IMO) is the default clock source, but it can be changed to an external clock source or the internal low-speed oscillator (ILO) using the CLK_CR register.
• What is the purpose of the VDDIO pin?
  The VDDIO pin is the power supply pin for the I/O buffers. It should be connected to a 1.8V to 5.5V power source, depending on the I/O voltage requirements.
• How do I use the CapSense feature on this microcontroller?
  The CapSense feature can be used by configuring the CapSense blocks and using the CapSense API provided in the PSoC Creator software. The CapSense blocks can be configured to detect changes in capacitance on the designated pins.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The GPIO pins can source or sink up to 25 mA of current. However, the total current sourced or sunk by all GPIO pins should not exceed 150 mA.
