Davicom offers cost-effective 2-, 3- and 6-port switch controllers for industrial and IIoT applications with low current consumption. DM8603 and DM8806 are 10/100Base-TX/FX 3- and 6-port Layer-2.5 switches with MII, RMII and Reverse MII. Additional features of DM8806 are IEEE 1588 Precision Time Protocol, IEEE802.3az Energy Efficient Ethernet, Fiber mode FEF, MSTP, WOL,  cut-through and 1.8, 3.3 and 5.0V tolerant I/Os. Both can be used as TX–FX Media Converters. DM9006 is a 10/100Base-TX 2-port Layer-2 switch controller with 8- and 16-Bit Bus Interface. DM9016 adds 32-Bit Bus Interface and external MII. DM9106 is similar to DM9016 with PCI Bus instead of parallel Bus Interface. The ports are individually configurable. Cascading- and ring-architectures can be realized. The switches generate and verify the TCP/UDP and IPv4 checksum to reduce application controller load. IGMP v1, v2, snooping, Spanning Tree Protocol (STP) and RSTP, IPv6 and Port Security are being supported.
