CH9434 chip equivalent, 4-uart chip.
* Operating voltage: 3.3V
* Support communication baud rate setting, with the baud rate range of 1200-4000000bps.
*UART has an independent FIFO buffer in each.
* MCU/DSP/embedded system.
* Industrial automation RS-485 communication.
* Serial server, card with multi se.
Power ground The internal power supply of the chip needs to be externally connected to
a decoupling capacitor if short-circuited with other VDD. The capacitance value is recommended not to be less than 0.1uF. Internal power supply of the chip, short-.
