The recommended crystal oscillator frequency for the CY8C4247BZI-L479 is 32.768 kHz. This frequency is used as the clock source for the internal real-time clock (RTC) and watchdog timer.
The CY8C4247BZI-L479 has a built-in USB 2.0 interface that can be configured as a device, host, or On-The-Go (OTG) interface. To configure the USB interface, you need to use the USBFS component in the PSoC Creator IDE or the USB API in the PSoC 4 MCU datasheet.
The CY8C4247BZI-L479 has an operating temperature range of -40°C to +85°C. However, the device can be operated at a reduced frequency and voltage range at temperatures above 70°C.
The CY8C4247BZI-L479 has a built-in CapSense component that can be used to implement capacitive touch sensing interfaces. To use the CapSense component, you need to configure the sensor pins, set up the CapSense tuning parameters, and use the CapSense API to read the sensor data.
The power consumption of the CY8C4247BZI-L479 in sleep mode depends on the sleep mode configuration and the clock frequency. In the lowest power sleep mode (Hibernate mode), the device consumes around 1.5 μA at 3.3 V and 25°C.
