CY8C24423A-24PVXI datasheet by Cypress Semiconductor

CY8C24423A-24PVXI Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The CY8C24423A-24PVXI 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 VCCD and VCCA pins?
  The VCCD pin is the power supply for the digital core, while the VCCA pin is the power supply for the analog circuits. Both pins should be connected to a 1.8V to 5.5V power source.
• How do I use the CapSense feature of this microcontroller?
  The CapSense feature can be used by configuring the CapSense blocks and sensors using the CapSense registers. The CapSense blocks can be configured to operate in self-capacitance or mutual-capacitance mode, and the sensors can be configured to operate in various modes such as proximity, touch, or slider modes.
• 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.
