W7100A

Ethernet ControllersThe 7100A device is an Ethernet controller SoC featuring an "un-attackable" hardware network engine for preventing network attacks such as flooding, spoofing and injection. The W5200 device does not have the on-chip microcontroller and needs to be connected to an external host via an SPI serial bus.**iMCU W7100A Ethernet Controller SoC** 8051-core SoC with hardwired TCP/IP protocol stack, MAC and PHY Hardwired TCP/IP Protocols: TCP, UDP, ICMP, IPv4 ARP, IGMP, PPPoE Support for ADSL connection (PPPoE Protocol with PAP/CHAP Authentication mode support) 10BaseT/100BaseTX Ethernet PHY Embedded Support for Auto-Negotiation (Full/Half Duplex) Support for Auto-MDIX Code memory: 2KB Boot ROM, 64KB Flash EPROM Data Memory: 256B Flash EPROM, 64KB RAM Memory Lock Function Up to 4 x 8-bit GPIO Ports (3.3V logic level, 5V tolerant, with Pull-Up/Pull-Down) Full-duplex UART Programmable Watchdog Timer DoCD & trade compatible debugger Power-Down mode P
