The recommended operating temperature range for CY25814SXIT is -40°C to +85°C, as specified in the datasheet. However, it's essential to note that the device can tolerate a wider temperature range during storage, which is -55°C to +125°C.
To configure the CY25814SXIT for USB 2.0 high-speed operation, you need to set the HS_EN pin high and ensure that the VBUS pin is connected to a valid USB 2.0 voltage source. Additionally, you should use a 24 MHz crystal oscillator as the clock source and configure the device for high-speed mode using the appropriate register settings.
The maximum cable length supported by CY25814SXIT for USB 2.0 high-speed operation is 3 meters, as specified in the USB 2.0 specification. However, it's essential to note that the actual cable length may vary depending on the cable quality, noise environment, and other factors.
To handle suspend and resume operations in CY25814SXIT, you need to monitor the SUSPEND pin and take appropriate actions when the device enters suspend mode. During suspend, the device reduces power consumption, and you should ensure that the system is properly configured to handle the suspend and resume events. You can use the device's built-in suspend and resume detection capabilities to simplify the process.
The power consumption of CY25814SXIT varies depending on the operating mode. In normal operation, the device consumes around 150 mA. In suspend mode, the power consumption reduces to around 50 μA. You can find more detailed power consumption information in the datasheet and application notes.
