Introduction

AI Translation

CH395 is an Ethernet protocol stack management chip designed for MCU systems to implement Ethernet communication. The chip integrates a 10/100M Ethernet MAC layer and PHY transceiver, fully compliant with IEEE802.3, and features built-in network protocol stack firmware including IP, ARP, ICMP, UDP, and TCP. MCU systems can conveniently perform network communication via CH395. The chip supports three communication interfaces: 8-bit parallel interface, SPI, and asynchronous serial port, allowing MCUs, DSPs, or MPUs to control CH395 for Ethernet communication through any of these interfaces.
