8051MCU, W3100A, PHY, SRAM and EEPROM, but WIZ100SR are just 8051MCU and W5100. In

-The transformer interface of WIZ100SR is different from EG-SR-7100A because of different PHY
-If existing EG-SR-7100A user changes the module to WIZ100SR without modifying the base board
circuit related to transformer interface the operation will not be normal
,
.
-there is not any difference in the firmware. If the base board circuit is correctly modified, WIZ100SR
can be applied as it is.
