The recommended crystal oscillator frequency for the CY8C4146AZI-S445 is 24 MHz, 32 kHz, or 32.768 kHz, depending on the application requirements.
The GPIO pins can be configured for analog or digital functionality using the Pin Configuration Register (PCR) and the Analog Mux Register (AMUX). Refer to the device's TRM (Technical Reference Manual) for more information.
The maximum current that can be sourced or sunk by the GPIO pins is 4 mA, but this can be increased to 8 mA or 12 mA by using the High-Current Pad Driver (HCPD) feature.
The CY8C4146AZI-S445 has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Register (WDT_CTRL). The watchdog timer can be set to reset the device or generate an interrupt if the timer expires.
The power consumption of the CY8C4146AZI-S445 varies depending on the operating mode. In Active mode, the current consumption is around 2.5 mA/MHz. In Sleep mode, the current consumption is around 1.5 μA, and in Hibernate mode, it is around 1 μA.
