ZLAN1043N is a powerful single-chip serial port to TCP/IP chip, which integrates 10/100M fast Ethernet MAC and PHY interfaces, UART serial ports, and software functions required for serial port to TCP/IP. Different from ordinary solutions, ZLAN1043N has three advantages: easy to use, stable and reliable, and low system cost. ZLAN1043N can be used to maximize the convenience of the design of TCP/IP and Internet interconnection products.

The convenience of ZLAN1043N is reflected in the fact that it is a real single-chip serial port to TCP/IP chip that can be used out-of-the-box, and UART to TCP/IP data transmission can be realized without any driver. After the chip is powered on, the user does not need to configure the parameters, because all the parameter configurations can be configured through the network port with ZLVircom software, and the user can configure all the internal parameters of the ZLAN1043N with one click through ZLVircom. As a TCP client, the ZLAN1043N automatically establishes a TCP connection, and as a TCP server, it automatically accepts the connection without any intervention from the user's MCU. All the user MCU needs to do is wait for the ZLAN1043N initialization to complete and then send and receive serial port (UART) data.

The stability of the ZLAN1043N is reflected in the fact that the internal TCP/IP protocol stack of the ZLAN1043N has been proven by years of commercial application practice. Internal includes: TCP, UDP, IPv4, IMP, ARP, HTTP, etc.
