The W5100 is a versatile, single-chip network interface chip with an integrated 10/100 Ethernet controller for high-integration, high-stability, high-performance, and low-cost embedded systems. With the W5100, you can make an Internet connection without an operating system. The W5100 is compatible with IEEE802.3 10BASE-T and 802.3u 100BASE-TX.
The W5100 integrates a fully hardware-proven, multi-year-proven TCP/IP stack, Ethernet media transport layer (MAC), and physical layer (PHY). The hardware TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP and PPPoE, which have been validated in many areas for many years. The W5100 also integrates 16KB of memory for data transfer. The W5100 does not require Ethernet control and requires simple port programming.
The W5100 provides three interfaces: a direct parallel bus, an indirect parallel bus, and an SPI bus. The interface between the W5100 and the MCU is very simple, just like accessing external memory.
The W5100 can be used in a variety of embedded applications, including:
- Home network equipment: set-top boxes, PVRs, digital media adapters
- Serial to Ethernet: Access Control, LED Display, Wireless AP, etc.
- Parallel to Ethernet: POS/Mini printer, copier
- USB to Ethernet: storage device, network printer
