CO2128 Ref Design Schematics
Micrel 10/100BaseT LAN and EBI Flash Memory Using iChip™ CO2128
Introduction
This reference design demonstrates the iChip™ CO2128 connected to a 10/100BaseTEthernet LAN via an RMII interface,
to a host processor via an RS232 interface, and to aflash memory chip via an EBI interface.
LAN access is based on iChip CO2128’s internal Ethernet MAC and an external MicrelKSZ8041NL chip.
The design is intended to connect to a host device through a standard EIA RS232 serialport.
Connect One’s AT+i™ commands are accepted at baud rates of up to 3Mbps.3Mbps.
Features
• Standard RS232 serial input channel
• Supports serial host interface rates of up to 3Mbps (250K, 1M, 1.5M, 3M)
• SSL3/TLS1 security implemented in hardware
• Data and Internet connection through a 10/100BaseT Ethernet controller
• Full hardware flow control
• Supports AT+i™ commands for Internet connectivity
