1.1 INTRODUCTION
The LAN9252 is an 2/3 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, or 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, analyses 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 application is comparable to a dual-ported memory (process memory), enhanced by special functions e.g. for consistency checking
(SyncManager) and data mapping (FMMU). Each FMMU performs the task of bitwise
mapping of logical EtherCAT system addresses to physical addresses of the device.
The scope of this document is to describe the EVB set-up for LAN9252 which supports
3-port mode and its jumper configurations. The LAN9252 is connected to an RJ45
Ethernet jack with integrated magnetics for 100BASE-T connectivity. A simplified block
diagram of the LAN9252 can be seen Figure 1-1.

Chapter 2. Board Details
DC 5V is applied through (J1) DC Socket, powered by a +5V external wall adapter.
Switch (SW1) needs to be ON position for the 5V to reach the 3.3V regulator. Glowing
of Green LED (D1) indicates successful generation of 3.3V o/p. This Power is supplied
to the LAN9252 and it has internal 1.2 V regulator which supplies power to the internal
core logic.
2.2.1 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 LAN9252 can be reset by pressing the reset
switch (SW2). The reset LED D2 will assert (red) when the LAN9252 is in reset condition.
For stability, a delay of approximately 180ms is added from the +3.3V o/p to reset
release.
2.3 CLOCK
2.2.2 Reset Out
The LAN9252 reset pin can be configured as an output to reset the SoC. The RST# pin
becomes an open-drain output and is asserted for the minimum required time of 80ms
LAN9252 requires an external 25Mhz crystal or clock.
By default, Short 1-2 of J14 header to connect the 25 MHz crystal Y1 to the internal
oscillator of the LAN9252.
