Designed for secure IP connectivity: acts as a security gap between the application and the network
Multiple hardware interfaces: USB 2.0 host and device, USART, RMII, two SPI, and two-wire
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 1.2V, while I/Os operate at 3.3V (typically 200mW)
Operates in the industrial temperature range at 48MHz
Packaged in a 64-pin LQFP form-factor (10x10x1.4mm)
RoHS-compliant
Supports LAN connectivity
Locally updateable firmware
iChip™ CO2064 is the most full-featured, lowest-cost Secure Ethernet Controller chip on the market today. The CO2064 acts as a co-processor to offload security and IP connectivity tasks from any host processor. The Secure Ethernet Controller is ideal for enabling devices to achieve secure, high-speed throughput and access to IP networks via 10/100BaseT LAN. Typically, only one man-month is needed for hardware engineering and adding IP connectivity commands to the host application.
The CO2064 firmware comes in two distinct flavors:
Flavor 'A'
10 concurrent active TCP/UDP sockets
Two listening sockets
Sending plain-text email messages
Sending and retrieving data from an FTP server
Serial-to-IP bridging in SerialNET™ mode
HTTP client
Flavor 'B'
Secure SSL3/TLS1 socket
9 non-secure TCP/UDP sockets
Network Time Client
Flavors can be quickly interchanged at will simply by sending an appropriate AT+i™ command for uploading a different flavor.
Security features include a random number generator, SHA-1/256 secure hash accelerator, AES-128/192/256 encryption accelerator, 3DES, and SSL3/TLS1.
The CO2064 uses an open software architecture that allows users to select and program the firmware flavor that provides the Internet protocols and other features required for their application.
The CO2064 loads its firmware and Internet configutation parameters either from an external SPI flash memory or accepts it from the host via one of the supported interfaces. The chip includes a 32-bit ARM7TDMI RISC processor and 256KB of SRAM.
