TCP/IP embedded Ethernet controller Megahunt COMW5

TCP/IP embedded Ethernet controller Megahunt COMW5

The COMW5 chip is a Hardwired TCP/IP embedded Ethernet controller that provides easier Internet connection to embedded systems. COMW5 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY embedded. 

Megahunt‘s Hardwired TCP/IP is the market-proven technology that supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE protocols. COMW5 embeds the 32Kbyte internal memory buffer for the Ethernet packet processing. If you use COMW5, you can implement the Ethernet application just by adding the simple socket program. It’s faster and easier way rather than using any other Embedded Ethernet solution. Users can use 8 independent hardware sockets simultaneously.
SPI (Serial Peripheral Interface) is provided for easy integration with the external MCU. The COMW5’s SPI supports 80 MHz speed and new efficient SPI protocol for the high speed network communication. In order to reduce power consumption of the system, COMW5 provides WOL (Wake on LAN) and power down mode.
