General Description
programmable Internet Protocol (IP) Communication
Controller chip that acts as a coprocessor to offload
security and IP network connectivity tasks from any
host processor. The IP Controller™ is ideal for
enabling devices to achieve secure, high-speed

to the host application, while the SerialNET™ serial-
to-IP bridging mode eliminates the need for any
change to the host application. AT+i commands are
intercepted by iChip, which puts the host device into
Internet mode. AT commands pass transparently from
the host processor to the communication peripheral
without any intervention by iChip.
