Connectone 公司的CO2144提供高性能的IP连接解决方案,具有最大化的硬化配置灵活性,包括有主机和通信接口如USB 2.0主机和设备,高速并行总线,SPI,以及UASRT等.安全特性包括硬件随机号码发生器(支持FIPS 140-2), SHA-1/256,可配置的AES键和3DES.中间件支持蜂窝,拨号,LAN或WiFi.本文介绍了CO2144的主要特性,方框图以及CO2144参考设计框图,详细电路图和材料清单(BOM).

iChipSec™ CO2144 provides a high-performance IP connectivity solution for devices that need security, will run high-speed applications, and need to keep power consumption to a minimum.
The chip offers you maximum hardware configuration flexibility, because it includes many interfaces to the host processor and communication peripherals, including USB 2.0 host and device, high-speed parallel bus, two SPI, one two-wire, and two USART interfaces.

Security features include a true hardware random number generator (supports FIPS 140-2), SHA-1/256, configurable AES key size (128, 192 or 256 keys), and 3DES, all with Peripheral DMA Channel. The chip supports multiple Certificate Authorities and both client-side and server-side authentication.

CO2144 includes 256KB SRAM onboard and requires external flash memory from which it can boot and execute when using the external bus interface. A single firmware flavor supports cellulaer, dial-up, LAN or WiFi.

Key Features & Benefits

Designed for secure IP connectivity: acts as a firewall between the application and the network Supports SSL3/TLS1 protocol for secure sockets, HTTPS and FTPS, WEP and WPA1/2 encryption for WiFi Up to 10 simultaneous TCP or UDP sockets, two listen sockets, Web server with two Web sites, SMTP and POP3 clients, MIME attachments, FTP and Telnet clients, and SerialNET™ mode for plug-and-play functionality Supports dial-up, cellular, WiFi or LAN connectivity in one firmware flavor Locally updateable firmware – IP stack and Internet configuration parameters are stored in separate flash memory Many hardware interfaces: USB 2.0 host and device, external bus, high-speed parallel, SPI, two-wire, and USARTs Includes 10/100BaseT Ethernet MAC Includes Random Number Generator and support for SHA-1/256, AES 128/192/256, and 3DES encryption in hardware Power-efficient: the core operates at 1.2-volts, while I/Os operate at 3.3-volts (typically 190 mW) Sleep mode further reduces power consumption Routing capability between Cellular and LAN/WiFi intefaces
Operates in the industrial temperature range at 48MHz

Packaged in a 144 ball LFBGA form-factor (10 x 10 x 1.4 mm)

RoHS-compliant

Nano Socket iWiFi™ is a secure serial-to-Wireless LAN device-server module that also acts as a bridge to connect serial devices to 802.11b/g Wireless LANs. It includes the iChip™ CO2144 IP Communication Controller™ chip, Marvell 88W8686 WiFi chipset and an on-board antenna. It is packaged in a RoHS-compliant ultra-slim form factor and uses an industry standard pin-out.

Nano Socket iWiFi offers much more than many other device servers on the market. It acts as a security gap between the application and the network; supports up to 10 simultaneous TCP/UDP sockets; two listening sockets; a web server with two websites; SMTP and POP3 clients; MIME attachments; FTP and TELNET clients, and SerialNET™ mode for serial-to-IP bridging.

Nano Socket iWiFi supports the SSL3/TLS1 protocol for secure sockets, HTTPS and FTPS, WEP, WPA and WPA2 WiFi encryption.

Nano Socket iWiFi minimizes the need to redesign the host device hardware. It easily inserts into headers on the host PCB and includes an on-board antenna. Minimal or no software configuration is needed for Nano Socket iWiFi to access the Wireless LAN.

Connect One’s high-level AT+i™ API eliminates the need to add WiFi drivers, security and networking protocols and tasks to the host application. The AT+i SerialNET operating mode offers a true plug-and-play mode that eliminates any changes to the host application.

Nano Socket iWiFi firmware – the IP stack and Internet configuration parameters – are stored in an on-board flash memory. The module is power-efficient: the core operates at 1.2V, while I/Os operate at 3.3V. Power Save mode further reduces power consumption.
