1 Product Description

The TPMC883 is a PCI Mezzanine Card (PMC) compatible module providing a single channel Gigabit
Ethernet 10 / 100 / 1000BASE-TX interface.

For highest data rates, the TPMC883 has a 64 bit, 133/100/66 MHz PCI bus interface and is capable
of full speed bus-master DMA operations utilizing maximum PCI bandwidth.

An Intel™ 82545EM Ethernet Controller (82545GM for RoHS compliant product) is used, which
supports 10, 100 and 1000 Mbit/s transmission rates for half and full duplex operation. The TPMC883
is capable of performing an auto negotiation algorithm which allows both link-partners to find out the
best link-parameters by themselves. The TPMC883 is widely user configurable via configuration and
status register access over the PCI bus. Front panel mounted LEDs indicate various network activities.

The TPMC883-10 provides a 10/100/1000 Mbit/s network connection via a front panel RJ45
connector. The port is galvanically isolated from the Ethernet Controller.

The operating temperature range is 0°C to +70°C.

3.2 Configuration EEPROM

After power-on or PCI reset the 82545 loads the initial configuration register data from the on board
configuration EEPROM.

See the 82545 Manual for more information.

1000 Indicates 1000BaseT Speed when LED is on
LINK Indicates Link established when Led is on

ACT Indicates Activity when LED is on

Figure 4-2 : LED Status Definitions

When both Speed LEDs are off, then a 10BaseT Speed connection is established.
