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.

GUIDE

Chapter 1. Overview
1.1 INTRODUCTION
The EVB-LAN9252-SPI board is intended to be a generic interface to many third party
processors used in EtherCAT Slave applications. The EVB-LAN9252-SPI is designed
to be a simple interface to the SPI port, with test points for power and ground. The eval-
uation board uses standard RJ45 connectors to connect to the EtherCAT system and
can be used to begin software development of the EtherCAT Slave code before the
final hardware is completed.

Chapter 2. EVB-LAN9252-SPI
2.1 EVB-LAN9252-SPI BOARD DESIGN
This section is an overview of the EVB-LAN9252-SPI board design and interface. The
board is intended to provide an interface to the SPI port of a microcontroller develop-
ment platform.

FIGURE 2-1: EVB-LAN9252-SPI TOP VIEW

2.1.1 SPI Headers

The four signals used for SPI communication with LAN9252 are exposed via headers
(J4-J7). These can direct the signals to the connector J3 as HBI or SPI, or be used to
fly-wire SPI between boards.
• J4 is connected to pin 19 of LAN9252. Connect a jumper between pins 1 and 2 to
route the signal to the D9 pin of J3. Jumper pins 2 and 3 to connect the signal to
pin SCK of J3. Alternatively, remove the jumper and wire the SPI Clock directly to
pin 2 of this header.
• J5 is connected to pin 50 of the LAN9252. Connect a jumper between pins 1 and
2 to route the signal to the D5 pin of J3. Jumper pins 2 and 3 to connect the signal
to pin SCS# of J3. Alternatively, remove the jumper and wire the SPI Chip Select
directly to pin 2 of this header.
• J6 is connected to pin 13 of the LAN9252. Connect a jumper between pins 1 and
2 to route the signal to the D1 pin of J3. Jumper pins 2 and 3 to connect the signal
to pin S0 of J3. Alternatively, remove the jumper and wire the SPI Slave Data Out
(SPI Master In) directly to pin 2 of this header.
• J7 is connected to pin 17 of the LAN9252. Connect a jumper between pins 1 and
2 to route the signal to the D0 pin of J3. Jumper pins 2 and 3 to connect the signal
to pin SI of J3. Alternatively, remove the jumper and wire the SPI Slave Data In
(SPI Master Out) directly to pin 2 of this header.

2.1.2 Power
When connected to a compatible development system through J3, the power test
points are to be used to confirm a proper voltage is present on the board. When wiring
the board to an external development board, the power test points are used to connect
an external power supply to the board.
• TP2 is tied to the 3.3V supply for the LAN9252 and the EEPROM for configura-
tion.
• TP3 is tied to the GND plane of the board. Additional GND access can be found
on J8 and J9.

2.1.3 Digital Interface Connector

EVB-LAN9252-SPI also has a mass interface connector on the bottom of the board.
This interface is used to connect many of the LAN9252 signals to third party develop-
ment platforms. These pins enable evaluation of HBI and SPI abstraction using
LAN9252. LAN9252 must also be configured with the correct ESI (EtherCAT Slave
Information) via EEPROM for these signals to be active.

FIGURE 2-2: EVB-LAN9252-SPI BOTTOM VIEW

2.2 INTERFACING WITH A THIRD PARTY PROCESSOR VIA SPI

The EVB-LAN9252-SPI can be connected to any microprocessor development plat-
form with exposed SPI pins. Once the pins have been connected properly, software
development can begin. The process can be broken down into three steps:

2.2.1 Connect pins

1. Connect the SPI pins to J4-J7.
2. Connect to Power Test Points to a bench supply, or 3.3V supply on the processor
board. Connect GND to TP3 and 3.3V to TP2.

DS50002604A-page 14  2017 Microchip Technology Inc.

 EVB-LAN9252-SPI

2.2.2 Configure Slave Software

There are four ways to program the processor to act as an EtherCAT Slave Device. The
different methods have different degrees of development needed to get to a solution
ready for the next stage in the process.
• When using an existing EtherCAT Slave solution, refer to the LAN9252 Migration
guide for details on how to replace the existing ET1100 interface libraries with the
LAN9252 equivalent. All other code can remain the same.
• When using a processor with a LAN9252 SDK, the Slave Source Code (SSC) tool
from Beckhoff can be used to automatically generate EtherCAT Slave code. In the
SDK are template files that are used to speed the process along. Refer to the
LAN9252 product page for the latest SDKs in the software library section.
• The EVB-LAN9252_HBIPLUS_SDK_V1.3 is an example of an SDK that has tem-
plate libraries to help with development.
• When using a processor that only has LAN9252 drivers, the Slave Source Code
tool can still be used. There will not be template files for faster development, and
the developer will need to manually add the LAN9252 driver files into the SSC and
develop the processor specific interface code to the necessary peripherals used.
- The LAN9252_C2000_Drivers_V1.0 is an example of the drivers provided
for the LAN9252.
• When using a processor without any drivers, the developer will need to develop
both the LAN9252 SPI interface libraries as well as the processor specific inter-
face code to the peripherals used.

2.2.3 Configure System from EtherCAT Master

Once the Slave Source Code has been developed and programmed onto the proces-
sor, the LAN9252 can be connected to an EtherCAT Master. Use the ESI files and
EEPROM configuration settings to properly set up the LAN9252 for the desired digital
communication. Debug and test the Slave code in the full EtherCAT development envi-
ronment.
