The IP210S is a very cost effective and highly integrated SoC(System-on-Chip).The embedded Ethernet transceiver, 64k bytes OTP, 32K bytes SRAM, 8-channel 8-bit ADC, 10/100Mbps Ethernet MAC/PHY, offload engine and 8051 support IP210S can be applied for variety applications such as Serial-to-Ethernet convertor, network sensor, remote control/monitoring, automatic test equipment and consumer electronics. The IP210S can support program running with embedded 64KB OTP ROM or external Flash memory for more flexible application. Since device drivers, network protocol stack and Ethernet offload engine are embedded inside the SoC, this design provides a neat and cost-effective solution. In addition to TP cable connection, the IP210S also provides the fiber cable connection to meet the requirement of long distance communication.
