The recommended crystal oscillator frequency for the CY8C4248BZI-L469 is 32.768 kHz. This frequency is used as the clock source for the internal real-time clock (RTC) and watchdog timer.
The CY8C4248BZI-L469 has a USB 2.0 Full-Speed interface that can be configured using the USBFS component in the PSoC Creator IDE. The USB interface can be configured as a device, host, or OTG (on-the-go) device. Refer to the PSoC Creator documentation and the CY8C4248BZI-L469 datasheet for more information.
The CY8C4248BZI-L469 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 (e.g., during device startup or shutdown).
The CY8C4248BZI-L469 has a secure boot feature that can be implemented using the PSoC Creator IDE. Secure boot ensures that only authorized firmware can be executed on the device. Refer to the PSoC Creator documentation and the CY8C4248BZI-L469 datasheet for more information on implementing secure boot.
The maximum current consumption of the CY8C4248BZI-L469 depends on the operating mode and the peripherals used. In active mode, the maximum current consumption is approximately 25 mA at 3.3V. In sleep mode, the current consumption is typically in the range of 1-5 μA.
