CY8C5248AXI-047 Frequently Asked Questions (FAQs)

• What is the recommended crystal oscillator frequency for this device?
  The recommended crystal oscillator frequency for the CY8C5248AXI-047 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 device for low power consumption?
  To configure the CY8C5248AXI-047 for low power consumption, you can use the device's power management features such as the sleep mode, hibernate mode, and dynamic voltage and frequency scaling (DVFS). You can also disable unused peripherals and adjust the clock frequency to reduce power consumption.
• What is the maximum operating temperature range for this device?
  The maximum operating temperature range for the CY8C5248AXI-047 is -40°C to +85°C. However, the device can be operated at temperatures up to +105°C for short periods of time during device startup or fault conditions.
• How do I implement secure boot on this device?
  To implement secure boot on the CY8C5248AXI-047, you can use the device's secure boot feature, which allows you to authenticate the firmware image during boot-up. This feature uses a combination of cryptographic algorithms and secure key storage to ensure the authenticity and integrity of the firmware.
• What is the maximum amount of flash memory that can be used for program storage?
  The CY8C5248AXI-047 has a total of 512 KB of flash memory, of which up to 448 KB can be used for program storage. The remaining 64 KB is reserved for the device's configuration and calibration data.
