iinChip™ W3150 Datasheet
Description
The iinChip™ W3150 is an LSI of hardware protocol stack that provides an easy, low-cost solution for high-
speed Internet connectivity for digital devices by allowing simple installation of TCP/IP stack in the hardware.
The W3150 offers system designers a quick, easy way to add Ethernet networking functionality to any
product. Implementing this LSI into a system can completely offload Internet connectivity and processing
standard protocols from the system, thereby significantly reducing the software development cost.
The W3150 contains TCP/IP Protocol Stacks such as TCP, UDP, ICMP, IPv4, ARP and PPPoE protocols, as
well as Ethernet protocols such as Data Link Control and MAC protocol. The total internal memory size is
16Kbytes, which is the buffer for transmit and receive operations.
The W3150 provides a local bus interface to various MCUs and standard MII(Media Independent Interface)
specification consisting of nibble data bus for Ethernet PHY devices.
The W3150 is a best-fitted device for embedded application with Internet-Connectivity including IP-Setop
Box, Internet-DVR, Internet phones, VoIP SOC chips, Internet MP3 players, handheld medical devices,
various industrial system monitoring and metering, and many other non-portable electronic devices such as
large consumer electronic products.
