• 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

1.1 INTRODUCTION
The LAN9252 is a 2-port EtherCAT® slave controller with dual integrated Ethernet
PHYs which each contain a full-duplex 100BASE-TX transceiver and support 100Mbps
(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 following order:
Port 0 -> EtherCAT® Processing Unit -> Port 1 -> Port 2.
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-DIG-IO setup, which supports a Digital I/O 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-DIG-IO is shown in
Figure 1-1.
