Abstract: A design scheme for low power supply voltage multi-channel UART is proposed to meet the need of multi-point communication,low power consumption,high speed and low error rate in the complex control occasions.Each channel is independently controlled,and the FIFO configured at the transmitter and receiver can temporarily store data during high-speed data transmission to avoid data loss.The circuit utilizes top-down design method and uses Cadence tool for synthesis and simulation.The test results show that the circuit meets the design requirements,and the simulation waveforms verify the integrity of data transceiver.
