The recommended oscillator crystal frequency for the DS89C430-MNG+ is 11.0592 MHz or 12 MHz, as specified in the datasheet. However, it's essential to note that the crystal frequency can be adjusted based on the specific application requirements.
The watchdog timer on the DS89C430-MNG+ can be configured using the WDTCON register. The WDTCON register allows you to set the watchdog timer period, enable or disable the watchdog timer, and select the clock source. Refer to the datasheet for more information on the WDTCON register and its bits.
The maximum current that can be sourced or sunk by the I/O pins of the DS89C430-MNG+ is 25 mA. However, it's recommended to limit the current to 15 mA or less to ensure reliable operation and prevent overheating.
The DS89C430-MNG+ has a built-in UART module that can be configured using the UARTCON and UARTBUF registers. The UART module supports asynchronous communication and can operate in various modes, including 8-bit or 9-bit data, 1 or 2 stop bits, and odd or even parity. Refer to the datasheet for more information on the UART module and its registers.
The power consumption of the DS89C430-MNG+ in sleep mode depends on the specific sleep mode and the clock frequency. In general, the power consumption in sleep mode can be as low as 10 μA. Refer to the datasheet for more information on the power consumption in different sleep modes.
