The recommended crystal oscillator frequency for the CY8C4147AZS-S475 is 24 MHz, 32 kHz, or 32.768 kHz, depending on the application requirements.
To configure the internal voltage regulator for optimal power consumption, set the VREG bit in the SYSMOD register to 1, and adjust the VREG_CTRL register to select the desired voltage regulator mode (e.g., low-power mode or high-performance mode).
The maximum current that can be sourced or sunk by the GPIO pins of the CY8C4147AZS-S475 is 25 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
To implement a watchdog timer in the CY8C4147AZS-S475, configure the WDT_CTRL register to enable the watchdog timer, set the watchdog timer period using the WDT_PERIOD register, and reset the watchdog timer periodically using the WDT_RESET register.
The maximum operating temperature range for the CY8C4147AZS-S475 is -40°C to +85°C, with a maximum junction temperature of 150°C.
