Note the following details of the code protection feature on Microchip devices:

• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

Information contained in this publication regarding device applications and the like is provided only for your convenience and may be
superseded by updates. It is your responsibility to ensure that your application meets with your specifications. MICROCHIP MAKES NO

1.1 INTRODUCTION

The LAN9252 is a 2-port EtherCAT® slave controller with dual integrated Ethernet
PHYs that each contains a full-duplex 100BASE-TX transceiver and support 100 Mbps
(100BASE-TX) operation. 100BASE-FX is supported via an external fiber transceiver.

Each port receives an EtherCAT frame, performs frame checking and forwards it to the
next port. Time stamps of received frames are generated when they are received. The
Loop-back function of each port forwards the frames to the next logical port if there is
either no link at a port, if the port is not available, or if the loop is closed for that port.
The Loop-back function of port 0 forwards the frames to the EtherCAT Processing Unit.
The loop settings can be controlled by the EtherCAT master.

Packets are forwarded in the order specified below. Note that Port 0 is the upstream
port and must connect to an EtherCAT master, while Port 1 is the downstream port.

The EtherCAT Processing Unit (EPU) receives, analyzes, and processes the EtherCAT
data stream. The main purpose of the EtherCAT Processing unit is to enable and coor­dinate access to the internal registers and the memory space of the ESC, which can be
addressed both from the EtherCAT master and from the local application. Data
exchange between master and slave applications is comparable to a dual-ported mem­ory (process memory), enhanced by special functions for consistency checking (Sync­Manager), and data mapping (FMMU). Each FMMU performs bitwise mapping of
logical EtherCAT system addresses to physical device addresses.

The scope of this document is to describe the EVB-LAN9252-DIGIO setup, which sup­ports a Digital I/O PDI Interface and corresponding jumper configurations. The
LAN9252 is connected to an RJ45 Ethernet jack with integrated magnetics for
100BASE-TX connectivity. A simplified block diagram of the EVB-LAN9252-DIGIO is
shown in Figure 1-1.

2.1 INTRODUCTION

This section includes subsections on the following EVB-LAN9252-DIGIO details:

• Power

• Resets

• Clock

• Configuration

• Mechanicals

2.2 POWER

2.2.1 +5V Power

Power is supplied to the LAN9252 by a +3.3V on-board regulator, which is powered by
a +5V external wall adapter (Manufacturer: TRIAD MAGNETICS and P/N:
WSU050-3000). The LAN9252 includes an internal +1.2V regulator which supplies
power to the internal core logic. Assertion of the D1 Green LED indicates successful
generation of +3.3V output. The SW1 switch must be in the ON position for the +5V to
power the +3.3V regulator.

EVB-LAN9252-DIGIO

USER’S GUIDE

2.3 RESETS

2.4 CLOCK

2.3.1 Power-On Reset

A power-on reset occurs whenever power is initially applied to the LAN9252 or if the
power is removed and reapplied to the LAN9252. This event resets all circuitry within
the LAN9252. After initial power-on, the EVB-USB7206 Evaluation Kit can be reset by
pressing the reset switch SW2. The reset LED D2 will assert (Red) if when the
LAN9252 is in reset condition. For stability, a delay of approximately 180 ms is added
from the +3.3V output to reset release.

The EVB-LAN9252-DIGIO utilizes an external 25 MHz 25 ppm crystal from Cardinal
Components Inc. (P/N: CSM1Z-A5B2C5-40-25.0D18-F).
