CH395 是以太网协议栈管理芯片，用于单片机系统进行以太网通讯。

CH395 芯片自带10/100M 以太网介质传输层（MAC）和物理层(PHY)，完全兼容IEEE802.3

10/100M 协议，内置了PPPOE、IP、DHCP、ARP、ICMP、IGMP、UDP、TCP 等以太网协议栈固件。

单片机系统可以方便的通过CH395 芯片进行网络通讯。

CH395 支持三种通讯接口：8 位并口、SPI 接口或者异步串口，单片机/DSP/MCU/MPU 等控制

器可以通过上述任何一种通讯接口控制CH395 芯片进行以太网通讯。-CH395 is the Ethernet protocol stack management chip for single-chip system for Ethernet communications. CH395 chip comes 10/100M Ethernet media transport layer (MAC) and physical layer (PHY), fully compatible with IEEE802.3 10/100M protocol, built-in PPPOE, IP, DHCP, ARP, ICMP, IGMP, UDP, TCP, etc. Ethernet protocol stack firmware. SCM system can easily through the CH395 chip for network communication. CH395 supports three communication interfaces: 8 parallel port, SPI interface or an asynchronous serial port, MCU/DSP/MCU/MPU and other controllers can be any of the above control CH395 chip communication interface for Ethernet communications.
