The recommended crystal oscillator frequency for the CY8C4247AZI-L485 is 32.768 kHz. This frequency is used as the clock source for the internal real-time clock (RTC) and watchdog timer.
The CY8C4247AZI-L485 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. The configuration is done through the USBFS component's API and requires setting up the USB clock, enabling the USB interface, and configuring the endpoint buffers.
The CY8C4247AZI-L485 has an operating temperature range of -40°C to +85°C. However, the device can be operated at a reduced temperature range of -20°C to +70°C for industrial applications, and -40°C to +125°C for automotive applications.
The CY8C4247AZI-L485 has a secure boot feature that ensures the authenticity and integrity of the firmware. To implement secure boot, you need to use the PSoC Creator IDE to generate a secure boot image, which includes a digital signature and a cryptographic hash of the firmware. The secure boot image is then stored in the microcontroller's flash memory.
The maximum current consumption of the CY8C4247AZI-L485 depends on the operating mode and the peripherals used. In active mode, the maximum current consumption is around 25 mA at 3.3 V. In sleep mode, the current consumption is around 1.5 mA, and in deep sleep mode, it is around 10 μA.
