Note the following details of the code protection feature on Microchip devices: · Microchip products meet the specification contained in their particular Microchip Data Sheet.
· Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions.
· There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
· Microchip is willing to work with the customer who is concerned about the integrity of their code.
· Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as "unbreakable."
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.

EVB-KSZ9893 EVALUATION BOARD
USER'S GUIDE
Chapter 1. Overview
1.1 INTRODUCTION
The EVB-KSZ9893 evaluation board is a plug-in card that interfaces directly with a mating Microchip host processor or controller board, such as the SAMA5D3 Ethernet Development System (EDS) board. It features the KSZ9893, a highly integrated networking device that incorporates a layer-2+ managed Gigabit Ethernet switch, two 10BASE-T/100BASE-TX/ 1000BASE-T physical layer transceivers (PHYs) and associated MAC units, and one MAC port configured as the RGMII interface. The board's two PHY ports are connected to RJ45 Ethernet jacks with integrated magnetics, and the RGMII MAC interface is brought out to a high-speed multi-pin (HS) connector.
Together, the EVB-KSZ9893 and the SAMA5D3-EDS provide a highly-flexible platform for evaluation of basic PHY/Switch features via static Control-Status Registers (CSRs) and development of firmware for advanced MAC/Switch features that require interaction with upper network layers (for example, IEEE1588 PTP, AVB, and RSTP/MSTP).
The scope of this document is meant to describe the EVB-KSZ9893 setup and its user interface features. A simplified block diagram of the board is shown in Figure 1-1.

EVB-KSZ9893 EVALUATION BOARD
USER'S GUIDE
Chapter 2. Getting Started
2.1 INTRODUCTION
The EVB-KSZ9893 evaluation board is designed as a plug-in card to interface directly with a mating Microchip host processor or controller board, such as the SAMA5D3-EDS Board, that supplies full power and provides full register access and configuration via In-Band Management Access (IBA), SPI, or I2C bus management.
2.2 POWER SOURCE
The EVB-KSZ9893 is completely bus-powered from its mating Microchip host processor or controller board. Input power is delivered via the high-speed multi-pin (HS) connector. Refer to Figure 2-3 and board schematics in Appendix B. "Schematics" for details.
2.2.1 Power Probe Points
The power probe points along with the ground test points are shown in Figure 2-2.
2.2.2 Current Access Rework/Probe Points
The EVB-KSZ9893 design is not intended to perform current measurements on the device. If needed, the current access points to measure the current consumptions of the KSZ9893 power rails are across the following series ferrite beads to the board powers. · DVDDL: FB2 · AVDDL: FB3 · VDDIO: FB6 · AVDDH: FB4 for 3.3V (default populate) and FB1 for 2.5V (default not populate)
Note: Populate either FB4 only or FB1 only. If 2.5V AVDDH is desired, FB4 should be "Do Not Populate (DNP)" and FB1 should be populated.
Remove the above ferrite beads and place the current probes in series across the power probe points (Section 2.2.1 "Power Probe Points") that are joined by the ferrite beads. See also Appendix B. "Schematics". Board LED components are connected to the VDDIO power rail, and thus the measured current is higher than the amount consumed by only the KSZ9893 device.
2.3 CLOCK
The EVB-KSZ9893 utilizes a 25 MHz crystal to generate the input reference clock for the KSZ9893 device. Refer to Figure 2-1 and the board schematics in Appendix B. "Schematics" for details.

2.4 RESET
2.4.1 Power-On Reset
The discrete RC/Diode (R12, C8, and D3) circuit provides power-on reset to the KSZ9893 device.
2.4.2 Manual Reset
The SW1 reset button can be pressed and released to provide manual reset to the KSZ9893 device after power-up. Refer to Figure 2-1 and the board schematics in Appendix B. "Schematics" for details.
2.5 BOARD FEATURES AND CONFIGURATION
The following sub-sections describe the board features and configuration settings.

2.6 USING THE EVB-KSZ9893
The EVB-KSZ9893 directly plugs into a mating Microchip host controller or processor board, such as the SAMA5D3-EDS Board, that delivers full power and provides full register access and configuration via IBA, SPI, or I2C bus management.
Together, the EVB-KSZ9893 and the SAMA5D3-EDS enable 10/100/1000-Mbps Ethernet traffic switching across all three data ports of the KSZ9893 device, with RGMII MAC Port 3 connecting to the SAMA5D3 processor and PHY Port 1 and Port 2 connecting via copper Ethernet cable (CAT-5 UTP or better) to external Ethernet devices. All KSZ9893 registers are accessible via IBA, SPI, or I2C bus management from the SAMA5D3-EDS Board, enabling full evaluation and firmware development for all KSZ9893 MAC/Switch features and interaction with upper network layers.
Refer to the SAMA5D3-EDS Board documentation on its usage.
Figure 2-4 shows the EVB-KSZ9893 connected to the SAMA5D3-EDS Board.
