The CP2200-GQ is a single-chip Ethernet Controller containing an integrated IEEE 802.3 Ethernet media access controller (MAC), 10Base-T physical layer (PHY) and 8kB non-volatile flash memory. It can add Ethernet connectivity to any microcontroller or host processor with 11 or more port I/O pins. The 8-bit parallel interface bus supports both Intel and Motorola bus formats in multiplexed and non-multiplexed mode. The data transfer rate in non-multiplexed mode can exceed 30Mbps. The on-chip flash memory may be used to store user constants, web server content, or as general purpose nonvolatile memory. The flash is factory preprogrammed with unique 48-bit MAC address stored in the last six memory locations. Having unique MAC address stored in the CP2200/1 often removes the serialization step from the product manufacturing process of most embedded systems. It has four power modes with varying levels of functionality.
Full/half duplex with auto-negotiation
Automatic polarity detection and correction
Automatic retransmission on collision
Automatic padding and CRC generation
Supports broadcast and multi-cast MAC addressing
Interrupt on received packets and Wake-on-LAN
8192byte ISP non-volatile memory
Power-on reset royalty-free TCP/IP stack with device drivers
