The recommended crystal oscillator frequency for the CY8C3245LTI-129 is 32.768 kHz. This frequency is used as the clock source for the device's real-time clock (RTC) and watchdog timer (WDT).
To configure the CY8C3245LTI-129's analog blocks for capacitive sensing, you need to use the CapSense component in PSoC Creator or ModusToolbox. This component provides a graphical interface for configuring the analog blocks, including the capacitive sensing pins, sensing modes, and filter settings.
The maximum current that can be sourced or sunk by the CY8C3245LTI-129's GPIO pins is 25 mA. However, it's recommended to limit the current to 10 mA or less to ensure reliable operation and to prevent overheating.
To implement a bootloader in the CY8C3245LTI-129, you can use the Bootloader component in PSoC Creator or ModusToolbox. This component provides a pre-built bootloader that can be customized to suit your specific requirements. You can also use the device's built-in bootloader, which can be accessed by pulling the BOOT pin low during reset.
The CY8C3245LTI-129's power consumption in sleep mode depends on the specific sleep mode and the device's configuration. In the lowest power sleep mode (Hibernate mode), the device's power consumption is typically around 1-2 μA. In other sleep modes, the power consumption can be higher, up to several hundred μA.
