CY8C3445LTI-078 - Infineon

CY8C3445LTI-078 Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for this microcontroller?
  The recommended crystal oscillator frequency for the CY8C3445LTI-078 is 32.768 kHz. This frequency is used as the clock source for the internal real-time clock (RTC) and watchdog timer.
• How do I configure the GPIO pins as analog or digital inputs?
  The GPIO pins on the CY8C3445LTI-078 can be configured as analog or digital inputs using the Pin Configuration Register (PCR). The PCR register is used to set the pin mode, drive mode, and input buffer mode for each GPIO pin.
• 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 on the CY8C3445LTI-078 is 25 mA. However, the total current sourced or sunk by all GPIO pins should not exceed 150 mA to ensure reliable operation.
• How do I implement a low-power mode on this microcontroller?
  The CY8C3445LTI-078 has several low-power modes, including Sleep, Hibernate, and Stop modes. These modes can be entered by setting the appropriate bits in the Power Mode Register (PMR). The microcontroller can also be woken up from these modes using various interrupts, such as timer interrupts or GPIO interrupts.
• What is the maximum operating temperature range for this microcontroller?
  The maximum operating temperature range for the CY8C3445LTI-078 is -40°C to +85°C. However, the microcontroller can be operated at temperatures up to 105°C for short periods of time, such as during device startup or shutdown.
