CY8C5488FNI-LP212T - Infineon

CY8C5488FNI-LP212T Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for this microcontroller?
  The recommended crystal oscillator frequency for the CY8C5488FNI-LP212T 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 CY8C5488FNI-LP212T 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 CY8C5488FNI-LP212T is 25 mA. However, it's recommended to limit the current to 10 mA or less to ensure reliable operation and prevent overheating.
• How do I implement a low-power mode or sleep mode on this microcontroller?
  The CY8C5488FNI-LP212T 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) and configuring the clock sources and peripherals accordingly.
• What is the maximum operating temperature range for this microcontroller?
  The CY8C5488FNI-LP212T has an operating temperature range of -40°C to +85°C. However, the device can be operated at temperatures up to +105°C for short periods of time, such as during device startup or fault conditions.
