CY8C20234-12SXI datasheet by Cypress Semiconductor

CY8C20234-12SXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The CY8C20234-12SXI 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 requirement.
• How do I use the CapSense feature in this microcontroller?
  The CapSense feature can be used by configuring the CapSense blocks and using the CapSense API provided by Cypress. The CapSense blocks can be configured using the CapSense Control Register (CS_CCR) and the CapSense Interrupt Register (CS_CIR).
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins is 25 mA.
