DS89C450-ENL+ Frequently Asked Questions (FAQs)

  • The recommended oscillator crystal frequency is 12 MHz, but the device can operate with crystals in the range of 10 MHz to 20 MHz.
  • The watchdog timer can be configured using the WDTCON register. Set the WDTEN bit to enable the watchdog timer, and set the WDTPS bits to select the timeout period (1.5 ms to 2048 ms).
  • The maximum current that can be sourced or sunk by the I/O pins is 25 mA. However, the total current sourced or sunk by all I/O pins should not exceed 100 mA.
  • The internal flash memory can be accessed using the Flash Memory Interface (FMI) module. The FMI provides a simple interface to read, write, and erase the flash memory. Refer to the datasheet for detailed instructions.
  • The POR pin is used to reset the device during power-up. When the power supply voltage rises above the POR threshold (typically 2.5 V), the device is reset. The POR pin can also be used as a manual reset input.
