The recommended oscillator crystal frequency for the DS80C323-ECD+ is 11.0592 MHz or 12 MHz, as specified in the datasheet. However, it's essential to note that the device can operate with a wide range of crystal frequencies, but the recommended values ensure optimal performance and accuracy.
The watchdog timer on the DS80C323-ECD+ can be configured using the WDTCON register. You need to set the WDTEN bit to enable the watchdog timer and configure the WDT period using the WDTP bits. The watchdog timer can be reset using the WDTCLR bit. Refer to the datasheet for more information on the WDTCON register and its bits.
The maximum current that the DS80C323-ECD+ can source or sink on its I/O pins is 25 mA. However, it's essential to note that the total current sourced or sunk by all I/O pins should not exceed the maximum total current rating of the device, which is 100 mA.
The DS80C323-ECD+ has a built-in UART module that can be configured using the UARTCON register. You need to set the UARTEN bit to enable the UART, configure the baud rate using the UARTBRG register, and set the UART mode using the UARTMODE bits. The UART transmit and receive pins are multiplexed with other functions, so you need to configure the pin multiplexing using the PCON register.
The power consumption of the DS80C323-ECD+ varies depending on the operating mode. In active mode, the typical power consumption is around 10 mA at 5V and 25°C. In idle mode, the typical power consumption is around 2 mA at 5V and 25°C. In power-down mode, the typical power consumption is around 10 μA at 5V and 25°C. Refer to the datasheet for more information on power consumption in different operating modes.
