特性 Features

The evaluation kit consists of the NCN26010BMNEVB

bridge board and the NCN26010XMNEVB 10BASE−T1S

evaluation board.

The bridge board provides a power connector that allows

feeding the boards with a DC supply of anything between

8 V and 28 V. For full operation, when a Raspberry Pi Model

3 is connected to the board, the power supply needs to be able

to provide 10 W of continuous power.

The NCN26010XMNEVB evaluation board, carrying the

NCN26010 has two RJ45 connectors that allow attaching a

twisted single pair data cable. For ease of use, standard cat 5

Ethernet cables can be connected to the RJ45 connectors.

Note that only one pair (connected to pin 1 and 2) of the RJ45

connector is used.

The SPI connection can be done through a PMOD

connector on the NCN26010 evaluation board, allowing the

connection to MCU demo and eval boards of various

vendors. One example of such an Eval board is onsemi’s

RSL10 BDK−GEVK.

To allow monitoring the SPI traffic, the EVB features a

0.1” pitched pin header that is easily accessible. This header

could also be used to connect a logic analyzer, allowing

tracing of the SPI signals while in full operation together

with a (not supplied) Raspberry Pi or any other suitable Host

MCU or SBC.

The bridge board not only acts as a power supply for the

NCN26010 evaluation board, but also powers a Raspberry

Pi that can be connected to the 40−pin female connector,

bringing the SPI and interrupt request signals from the

NCN26010 MACPHY to the corresponding pins on the

Raspberry Pi SBC.

After trying different models of Raspberry Pi single board

computers, onsemi got best results with Raspberry Pi 3B and

3A+ models running “off the shelf” Raspberry OS with

some software tools installed.

See section “Raspberry Pi Setup and Operation” for a list

of suggested tools.

When using a Raspberry Pi model 3 with a 10/100

Ethernet interface, T1S can be bridged with this port

allowing connection to a regular PC.
