XR88C681CP/28 Frequently Asked Questions (FAQ)

  • The recommended operating temperature range for XR88C681CP/28 is -40°C to +85°C, as specified in the datasheet. However, it's essential to note that the device can tolerate a wider temperature range during storage, typically from -65°C to +150°C.

  • To ensure reliable data transmission over the UART interface, it's crucial to follow proper signal termination, use a suitable baud rate, and implement flow control mechanisms such as RTS/CTS or XON/XOFF. Additionally, consider using a UART buffer or FIFO to handle data transmission and reception.

  • The maximum clock frequency supported by the XR88C681CP/28 is 24 MHz. However, the device can operate at lower frequencies, and the clock frequency can be adjusted using the clock divider or prescaler.

  • To configure the XR88C681CP/28 for low-power operation, you can use the power-down mode, which reduces the power consumption to a minimum. Additionally, you can adjust the clock frequency, disable unused peripherals, and use the idle mode to minimize power consumption.

  • The maximum current rating for the XR88C681CP/28's I/O pins is typically 4 mA per pin, with a total current limit of 100 mA for all I/O pins combined. It's essential to ensure that the current drawn from the I/O pins does not exceed these ratings to prevent damage to the device.
