CH395L Description

Short technical summary and product information.

The WCH CH395L is an Ethernet protocol stack management chip designed for seamless Ethernet communication within MCU systems. It integrates both the 10/100M Ethernet Media Access Control (MAC) and Physical Layer (PHY), ensuring full compatibility with the IEEE802.3 protocol. This chip simplifies network integration by providing a built-in Ethernet stack firmware that supports essential protocols such as IP, DHCP, ARP, ICMP, IGMP, UDP, and TCP.

Connectivity is flexible, with support for three distinct communication interfaces: an 8-bit passive parallel port, an SPI interface capable of up to 30MHz, and a UART interface supporting speeds up to 3Mbps. This allows controllers like DSPs, MCUs, and MPUs to interface with the CH395L for Ethernet communication. The chip also includes 8 independent socket pairs for simultaneous data transmission and reception, a 24KB RAM buffer for Ethernet data, and a 4KB EEPROM.

The CH395L is available in LQFP128 and LQFP64M lead-free packages, compatible with RoHS standards. It supports automatic MDI/MDIX line conversion and various address filtering modes, enhancing its utility in diverse networking applications.
