CY8C24794-24LTXIT datasheet by Cypress Semiconductor

CY8C24794-24LTXIT Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for this microcontroller?
  The CY8C24794-24LTXIT 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 VREF pin?
  The VREF pin is used as a reference voltage for the analog-to-digital converter (ADC). It should be connected to a stable voltage source, typically VCC or an external reference voltage.
• How do I use the CapSense feature on this microcontroller?
  The CapSense feature is enabled by configuring the CapSense registers (CSR) and using the CapSense API provided by Cypress. The API provides functions for initializing, scanning, and processing CapSense data.
• 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. However, it's recommended to limit the current to 10 mA or less to ensure reliable operation.
