DM9010Ep product brief ethernet controller with general processor interface june 2008 rev.1.0 the dm9010 is a fully integrated and cost -effective single chip fast ethernet mac controller with a general processor inte rface, a 10/100m phy and 16k byte sram. it is designed with low power and high pe rformance process that support 3.3v with 5v tolerance. the dm9010 also provides a mii interface to connect hpna device or other transceivers that support m ii interface. the dm9010 supports 8-bit, 16-bit and 32-bit up interfaces to internal memory accesses for different processors. the phy of the dm9010 can interface to the utp3, 4, 5 in 10base-t and utp5 in 100base-tx. it is fully compliant with the ieee 802.3u spec. its auto-negotiation function will automatically configure the dm9010 to take the maximum advantag e of its abilities. the dm9010 also supports ieee 802.3x full- dupl ex flow control. this programming of the dm9010 is very simple, so user can port the software drivers to any system easily. block diagram led tx+/- rx+/- autonegotiation rx machine tx machine mac mii - / phyceiver processer interface - eeprom interface 100 basetx transceiver external mii interface memory management internal sram & control status registers 100 base - tx pcs 10 base t tx rx auto mdix & mii management control mii register
