CH9121 Datasheet Network And Uart Transparent Transmission

Manufacturer: Unknown Manufacturer

Overview: CH9121 Datasheet 1 Network and UART Transparent Transmission Chip CH9121 Manual Version: 2B 1. Overview 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 puter software or serial mands, which is convenient and quick. The figure below is a general application block diagram of CH9121.
