Reference esign Micrel 0/00aseT LN and SPI Flash Memory Using ihip O0SE Revision History Version ate escription.0 November 00 Original release Introduction This reference design demonstrates the ihip O0SE Secure Ethernet ontroller connected to a 0/00aseT Ethernet LN via an RMII interface, to a host processor via an RS interface, and to a flash memory chip via an SPI interface. LN access is based on ihip O0SE s internal Ethernet M and an external Micrel KSZ0NL chip. The design is intended to connect to a host device through a standard EI RS serial port. onnect One s Ti commands are accepted at baud rates of up to Mbps. Features Standard RS serial input channel Supports serial host interface rates of up to Mbps (0K, M,.M, M) SSL/TLS security implemented in hardware ata and Internet connection through a 0/00aseT Ethernet controller Full hardware flow control Supports Ti commands for Internet connectivity Reference esign This reference design outlines the connections required to link an ihip O0SE Secure Ethernet ontroller with a 0/00aseT Ethernet LN and an external flash memory chip, based on the block diagram, below. The host is connected to ihip O0SE via an RS serial input channel. The external 0/00aseT Ethernet PHY is connected via an RMII interface. The external flash memory (MP0-VMPG from STMicroelectronics) is connected via an SPI interface. onnect One Ltd. opyright November 00-0-0
