CY8C27443-24PVXIT datasheet by Cypress Semiconductor

CY8C27443-24PVXIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The CY8C27443-24PVXIT 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 circuitry. 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 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.
