The Jacinto7 EVMs are development and evaluation systems that enable developers to write software and develop hardware around the Jacinto7 family of processors. The main elements of the system are available on the EVM system itself. This gives developers the basic resources needed for most general-purpose type projects that encompass the Jacinto7 processor.
Beyond the basic resources provided, additional functionality can be added via expansion cards.
This Technical User’s Guide describes the hardware architecture of the Jacinto7 EVM – Quad Port Ethernet Expansion board (QP-ENET), which is interfaced with J7 EVM boards through Serial Ethernet Expansion Connector.
Key features of QP-ENET:
The orderable part number is provided in the table below:

There is elevated heat on the processor/heatsink: use caution, particularly at elevated ambient temperatures. Although the processor/heatsink is not a burn hazard, caution should be used when handling the EVM due to increased heat in the area of the heatsink.
Components installed on the product are sensitive to Electrostatic Discharge (ESD). TI recommends that this product be used in an ESD controlled environment. This may include a temperature and/or humidity controlled environment to limit the build-up of ESD. TI also recommends using ESD protection such as wrist straps and ESD mats when interfacing with the product.
The product is used in the basic electromagnetic environment as in laboratory condition and the applied standard will be as per EN IEC 61326-1:2021.
QP-ENET Expansion boards shall be interfaced with Jacinto7 J784S4XG01EVM in bottom mating configurations. The images below show the J7AHP EVM board connectors J51 and J52, which mate with the QP-ENET board as an example, with expansion connectors J3 on the QP-ENET mated to the SGMII Expansion connectors on the J7AHP EVM. It is valid to support/install on only one QP-ENET board, and in either location.
This assembly procedure example is given for mating the QP-ENET board with the J784S4XG01EVM board.
This section explains the Hardware Architecture of QP-ENET Expansion Board in detail.
