(i) Ethernet switch chip AR8236

I. Overview

The AR8236 is a 6-port Gigabit Ethernet switch chip that has a high performance lookup table that can store 1024 MAC addresses, 16 VLAN tables, QoS It supports the IEEE802.3 standard, 8236 supports multiple configurations, and we can configure internal registers via EEPROM or Mdc/mdio interface. AR8236 Add two bytes of head at each frame, we can use this head to configure switch register, address lookup table, VLAN,MIB, etc. PORT0 Port supports mii-phy and rmii-phy two modes connected to external CPU; it contains a 1KB address lookup table, The information of the address lookup table can be accessed through the CPU interface through read and write, and each input address can be configured to be static.

8236 the system diagram is as follows:
