The recommended crystal oscillator frequency for the CY8C4147AZI-S453 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 register to the desired voltage level (1.8V, 1.9V, or 2.0V) and enable the voltage regulator in the PMIC (Power Management IC) module.
The maximum current that can be sourced or sunk by the GPIO pins of the CY8C4147AZI-S453 is 4 mA per pin, with a total current limit of 100 mA for all GPIO pins combined.
To implement a watchdog timer in the CY8C4147AZI-S453, configure the WDT (Watchdog Timer) module by setting the WDT period and enabling the watchdog timer. The watchdog timer can be reset using the WDT reset register or by executing a specific instruction sequence.
The maximum operating temperature range for the CY8C4147AZI-S453 is -40°C to +85°C, with a storage temperature range of -40°C to +125°C.
