CO2064SEC Reference Design schematics
Micrel 10/100BaseT LAN and SPI Flash Memory Using iChip™ CO2064SEC
Introduction
This reference design demonstrates the iChip™ CO2064SEC Secure Ethernet Controlconnected to a 10/100BaseT Ethernet LAN via an RMII interface,
to a host processoran RS232 interface, and to a flash memory chip via an SPI interface.
LAN access is based on iChip CO2064SEC’s internal Ethernet MAC and an externalMicrel KSZ8041NL chip.
The design is intended to connect to a host device through a standard EIA RS232 seriaport. Connect One’s AT+i™ commands are accepted at baud rates of up to 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
