W7100 MCU

Korea fabless semiconductor company WIZnet Inc. debuts the W7100 Internet microcontroller (iMCU) that integrates a hardwired TCP/IP core with an 8051 processor. Combined with a 64Kbyte SRAM and 32Kbyte internal buffer, the device eases high-performance Internet connections.

WIZnet's hardwired W5100 TCP/IP stack includes an Ethernet MAC and PHY for industrial and multimedia applications. Now the company is combining it with an 8051 MCU core to create a one-chip solution.

An embedded Internet implementation requires an MCU, at least three interfaces such as Ethernet, plus the memory. The W7100 integrates these in one chip, easing the implementation at less costs. Also, even without any knowledge about TCP/IP protocol, W7100 users can design various applications with the simple SOCKET programs.

The W7100 Internet MCU is fully software-compatible with industrial standard 8051. It features pipelined RISC architecture which enables execution of instructions 4-5x faster than a standard 8051. ADSL connection is achieved with PPPoE Protocol with PAP/CHAP Authentication mode support, and it is hardwired with TCP/IP protocols: TCP, UDP, ICMP, IPv4 ARP, IGMP, PPPoE and Ethernet. Plus it touts a DoCD compatible debugger.

It is priced at $ 5.20 at 100K quantities. iMCU7100EVB evaluation board is offered at a discounted price of $49. Regular price for the evaluation board is $99.
