iChip™ CO2064, CO2128 and CO2144 are full-featured programmable IP Communication Controller™ chips that act as coprocessors to offload security and IP connectivity tasks from any host processor. They are ideal for enabling devices to achieve secure, high-speed throughput and access to IP networks via 10/100BaseT LAN or 802.11b/g wireless LAN, and cellular or dial-up modems. Typically only one man-month is needed for hardware engineering and adding IP connectivity commands to the host application.

While the CO2128/CO2144 include a complete set of features, the CO2064 uses an open software architecture that enables users to select and program different firmware flavors, each providing a unique subset of Internet protocols and features.

The CO2128/CO2144 firmware supports up to 10 simultaneous active TCP/UDP sockets and two listening sockets; HTTP, SMTP, MIME, POP3, FTP and TELNET clients; a web server with two websites: one for configuring the CO2128/CO2144 and one for the application; and serial-to-IP bridging.

The CO2064 comes in two firmware flavors:

Flavor A offers 10 active TCP/UDP sockets and two listening sockets; sending ASCII e-mails; sending and retrieving data from an FTP server, and serial-to-IP bridging in SerialNet™mode.

Flavor B supports one secure TCP/UDP socket plus 9 non-secure sockets.

Security features in the CO2064 include the hardware implementation of a random number generator, SHA-1 secure hash accelerator, AES-128/256 encryption accelerator, 3DES, SSL3/TLS1, RSA, RC-4 and MD-5. The CO2128 includes, in addition to the above, WEP, WPA, and WPA2 encryption for WiFi.

CO2064 loads its firmware and Internet configuration parameters either from an external SPI flash memory, or accepts it from the host via one of the supported interfaces. Firmware can be updated locally via RS232.

CO2128/CO2144 load their firmware from an external EBI flash memory. Firmware can be remotely updated via sockets, FTP or HTTP.

All three iChips include a 32-bit ARM7TDMI RISC processor and 256KB of embedded high-speed SRAM. Basic peripherals for all models include USB v. 2.0 full-speed host and device port; 10/100BaseT Ethernet MAC with MII/RMII, USART and SPI interfaces.

Both CO2064 and CO2128/CO2144 feature Sleep mode for energy savings. The iChips come in a 64-pin (CO2064), 128-pin (CO2128) or 144-pin (CO2144) LQFP RoHS-compliant package.
