iMCU W7100A is the one-chip solution which integrates an 8051 compatible microcontroller,
The TCP/IP core is a market-proven hardwired TCP/IP stack with an integrated Ethernet
Pipelined architecture which enables execution of instructions 4~5 times faster than a
10BaseT/100BaseTX Ethernet PHY embedded
Power down mode supported for saving power consumption
Hardwired TCP/IP Protocols: TCP, UDP, ICMP, IPv4 ARP, IGMP, PPPoE, Ethernet
Auto Negotiation (Full-duplex and half duplex), Auto MDI/MDIX
ADSL connection with PPPoE Protocol with PAP/CHAP Authentication mode support
8 independent sockets which are running simultaneously
32Kbytes Data buffer for the Network
Network status LED outputs (TX, RX, Full/Half duplex, Collision, Link, and Speed)
Not supports IP fragmentation
2 Data Pointers (DPTRs) for fast memory blocks processing
