Fully Hardwired TCP/IP – W3150A+
(TCP/IP Core + MAC)

W3150A+ TCP/IP Product Information PDF

The W3150A+ 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 W3150A+ offers a quick and easy way to add Ethernet networking functionality to any products. Implementing this LSI into a system can completely provide Internet connectivity and process standard protocols by significantly reducing the software development cost as well development time which is most important in today time-to market. The W3150A+ contains TCP/IP Protocol Stacks such as TCP, UDP, ICMP, IPv4, ARP and PPPoE protocols, as well as Ethernet protocols such as MAC protocol. The total internal memory size is 16Kbytes, which is used as the buffer for data transmission and receipt. The W3150A+ provides three different interfaces like direct, indirect bus interfaces and SPI(Serial Peripheral Interface) to connect with MCUs and standard MII(Media Independent Interface) composed of nibble data bus to connect with Ethernet PHY devices.
The W3150A+ is a best-fitted device for embedded application including IP-Settop Box, Internet-DVR, Internet phones, VoIP SOC chips, Internet MP3 players, handheld medical devices, various industrial system for monitoring and metering, and any other non-portable electronic devices such as large consumer electronic products.
