Description

The W5100S is a Hardwired TCP/IP embedded Ethernet Controller that enables easier Internet Connection for embedded Systems using SPI (Serial Peripheral Interface) and Parallel Bus.
W5100S suits users in need of stable Internet Connectivity Best, using a single chip to implement TCP/IP Stack, 10/100 Ethernet MAC, and PHY. The implemented Hardwired TCP/IP stack supports TCP, UDP, IPv4, ICMP, ARP, IGMP, and PPPoE which has been proven through various Applications over many years.?W5100S uses a 16 Kbytes Internal Buffer as its Data Communication Memory.
By using W5100S, users can implement the Ethernet Application they need by using a simple socket Program instead of handling a complex Ethernet Controller. It is possible to use 4 independent hardware sockets simultaneously.

Features:

48QFN lead-free package (7x7mm, 0.5mm pitch)
Host Interface: SPI (up to 70MHz, mode 0, 3) and Parallel System Bus with 2 Address signals and 8 Bits Data
Unattackable hardware engine for preventing network attacks such as flooding, spoofing, injection
4 Independent hardware sockets simultaneously
supports various Internet Protocols: TCP, UDP, WOL over UDP, ICMP, IGMPv1/v2, IPv4, ARP, PPPoE
Internal 16 Kbytes memory for TCP/IP packet processing
socket-less commands possible: ARP request and ping requests
10BaseT / 100Base TX Auto Negotiable Ethernet PHY Embedded
Auto-MDIX in auto-negotiation mode (Half/Full Duplex, 10/100 MBit/s speed)
IP fragmentation not supported, ARP-cache table will not be stored permanently
3.3V operating voltage with 5V I/O signal tolerance
LED outputs (full/half duplex, link, 10/100 speed, active)
Reduced heat dissipation (W5500: 40?? / other chips : 60-70??)
