Overview CH9434 is a SPI to 4-UART transfer chip, which provides four full duplex nine-line UARTs, and is used to extend UART for MCU/embedded system.

CH9434 includes four UARTs compatible with 16C550 and supports up to 4Mbps baud rate communication.

Key Features

  • 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 direction, sending 1536 bytes and receiving 2048 bytes.
  • Four fully independent UARTs, compatible with 16C550 and enhanced.
  • Support 5/6/7/8 data bits and 1/2 stop bits.
  • UARTs support odd, even, no parity, blank 0, mark 1 and other verification methods.
  • Support the commonly used MODEM communication signals.
