mikroETH 100
All Mikroelektronika’s development systems feature a large number of peripheral
modules expanding microcontroller’s range of application and making the
process of program testing easier. In addition to these modules, it is also
possible to use numerous additional modules linked to the development system
through the I/O port connectors. Some of these additional modules can operate
as stand-alone devices without being connected to the microcontroller.

mikroETH 100
The mikroETH 100 additional board is used to connect the microcontroller installed in some device to the Ethernet
network.
Key features:
- IEEE 802.3™ Compliant Fast Ethernet Controller;
- Integrated MAC and 10/100Base-T PHY;
- Hardware Security Acceleration Engines;
- 24-Kbyte Transmit/Receive Packet Buffer SRAM;
- Operating voltage range of 3.0V to 3.6V; etc.

How to connect the board?
The mikroETH 100 additional board is connected to the microcontroller in some device via pads CN1 and CN2.
Connection with the Ethernet network is established via the RJ45 connector. Jumpers J1-J4 are used to select PSP
mode (Parallel Slave Port interface), table 1.
