Ethernet EEPROM (U500)
The EEPROM connected to the Ethernet controller can be used to
store specific confguration data that are automatically loaded into the
LAN91C111 following a hardware-reset. The EEPROM can be
programmed on-board via the Ethernet controller.
Please refer to the
SMSC LAN91C111 Ethernet controller datasheet for details
.
The MAC address is pre-programmed into the EEPROM (U500) at
time of delivery (
refer to section 9.1

10/100Base-T Interface
The phyCORE-LPC2292/94 has been designed exclusively for
operation in 10/100Base-T networks. The 10/100Base-T interface with
its signals LAN_LEDA and LAN_LEDB extends to phyCORE-
connector X1. The MII interface of the LAN91C111 is not available
on the phyCORE-connector. However, these signals are routed to an
optional connector X500 that populates the debugCORE-LPC2292
variant.
Additional external circuitry is required to connect the module to an
existing 10/100Base-T network. It should be noted that the 3.3 V
version of the LAN91C111 controller is used on the
phyCORE-LPC2292/94.
Please refer to the SMSC Ethernet controller
datasheet for details on the external circuitry design
. This circuitry is
also available from PHYTEC on an Ethernet adapter module, order
code EAD-003 (
).
