Micrel/Microchip has developed switches which can expand one Ethernet port into 1+n fully independent ports, supported by the so-called Tail Tagging mode. This enhancement establishes a virtual Multiport when only one physical Ethernet port is available on the CPU - by choosing another PHY.
The embOS/IP switch board features an NXP Kinetis K66 CPU clocked at 180 MHz, with 256 KB SRAM as well as 2 MB Flash memory, the Micrel/Microchip switch PHY KSZ8794CNX with three usable Ethernet ports and an on-board version of Segger’s popular J-Link debug probe for quick and easy debug access to the Kinetis core MCU.
The embOS/IP Switch board is powered by the USB device connector (B-type connector). Current consumption drawn depends on the configuration and connected Ethernet links, but the board will only draw 140mA in idle mode.
