CH9121 Ethernet to 2-CH UART Transparent Transmission IC - LQFP-64

CH9121 Ethernet to 2-CH UART Transparent Transmission IC -  LQFP-64

Datasheet

CH9121 is a chip realizing transparent transmission between network and UART. It integrates TCP/IP protocol stack, which can realize bidirectional transparent transmission between network data packets and serial data. It has 4 working modes: TCP CLIENT, TCP SERVER, UDP CLIENT and UDP SERVER. The serial baud rate can be up to 921600bps. It can be easily configured by upper computer software or serial commands, which is convenient and quick.

CH9121 is a chip for transparent transmission between network and UART, and realizes bidirectional transparent transmission of serial data and network data. It supports 4 working modes (TCP CLEINT/SERVER, UDP CLIENT/SERVER), and the serial baud rate supported ranges from 300bps to 921600bps. Before use, the network parameters and UART parameters of the chip shall be configured by upper computer software NetModuleConfig.exe or serial commands. After the configuration is completed, CH9121 will save the configuration parameters to the internal storage space. And after the chip is reset, CH9121 will work according to the saved configuration value.
