DS89C21TMX Frequently Asked Questions (FAQs)

  • The maximum clock frequency for the DS89C21TMX is 33 MHz, but it can be overclocked up to 40 MHz with careful consideration of power supply and thermal management.
  • The DS89C21TMX has a built-in watchdog timer that can be enabled by setting the WDTEN bit in the WDCON register. The watchdog timer can be configured to timeout after 16, 32, 64, or 128 clock cycles.
  • The DS89C21TMX is designed to operate at 3.3V, but it can tolerate a maximum voltage of 3.6V. Using a 5V power supply is not recommended and may damage the device.
  • The UART on the DS89C21TMX can be configured using the UARTCON and UARTSTA registers. The baud rate, data bits, parity, and stop bits can be set using these registers.
  • Yes, the DS89C21TMX can be used with an external crystal oscillator. The crystal oscillator frequency can be set using the XTALFREQ bits in the SYSCON register.
