Abstract
An UART interface circuit is provided in the invention. The UART interface circuit is configured in an electronic device. The UART interface circuit includes a baud-rate generating circuit, a control circuit, and a receiving circuit. The baud-rate generating circuit is configured to generate a baud rate and a start-bit cycle. The control circuit obtains the wakeup stable time from the wakeup time circuit of the electronic device and obtains the start-bit cycle from the baud-rate generating circuit. The receiving circuit is configured to capture data from the start bit or the first data bit of UART data. When the electronic device is woken up by the UART data, the control circuit compares the start-bit cycle with the wakeup stable time to direct the receiving circuit to start capturing data from the start bit or the first data bit of the UART data.
