The KSZ8851-16MLL comes with a 48-pin, lead-free LQFP (7mm x 7mm) package and provides an ideal solution for applications requiring high-performance from single-port Ethernet Controller with 8-bit or 16-bit generic processor interface. The KSZ8851-16MLL offers the most costeffective solution for adding high-throughput Ethernet connectivity to traditional embedded systems. This evaluation board is designed as a stand alone without microcontroller or M16C on board. By default the KSZ8851-16MLL-Eval board comes with an operation of 16-bit bus mode, Little Endian mode and disabled EEPROM for KSZ8851-16MLL device. Customer may wire the board for his desired interface. The purpose is to provide a simple tool that can be used to evaluate the KSZ8851-16MLL device by connecting via headers to customer provided Microcontroller or NonPCI hardware platform. Micrel provides a basic software driver based on the 8 or 16-bit bus solution and different operating system platforms to evaluate the KSZ8851-16MLL functionality and performance. The software includes a configuration utility to allow quick and easy device setup, initialization and transmit/receive packet. All KSZ8851-16MLL configuration pins and host interface signals are accessible either by jumpers, test points or headers. 2.0 • • • • • • • • • • • • 3.0 Board Features One KSZ8851-16MLL 48-pin Single-Port Ethernet Controller with shared data bus for host interface Single +5V/GND power input from headers RJ-45 Jack for Fast Ethernet cable interface HP Auto-MDIX for automatic detection and correction for straight-through and crossover cables Two on board LDO voltage regulators, one for VDD_IO and the other for VDD_A3.3 One AT93C46 for external EEPROM interface Two LED indicators for port status and activity One LED indicator for 3.3V output ready One LED indicator for Power Management Event (PME) output status Jumpers to configure strapping pins and VDD_IO voltage option Headers to wire the host interface from external hardware platform Manual reset button for quick reboot after re-configuration of strapping pins Evaluation Kit Contents The KSZ8851-16MLL Evaluation Kit includes the following hardware: • KSZ8851-16MLL Evaluation Board The KSZ8851-16MLL Data Sheet and Hardware Design Package with the following collaterals that can be downloaded from Micrel’s website at http://www.micrel.com • KSZ8851-16MLL Eval Board Schematic (PDF and OrCAD DSN file) • KSZ8851-16MLL Eval Board Gerber File (PDF version included) • KSZ8851-16MLL Eval Board User’s Guide (this document and included BOM) • KSZ8851-16MLL IBIS Model Micrel, Inc.

Header JP1 – Host Interface Connection for Control and Power 4.2 Jumper Setting & Definition The KSZ8851-16MLL-Eval does not require any jumper for normal operation except the VDD_IO option. During power-up, the KSZ8851-16MLL is configured using the chip’s internal pull-up and pull-down resistors with its default strapping pin values which will set this device in operation of 16-bit bus mode, little endian and without EEPROM. Jumpers are provided to override the default settings, allowing for quick configuration and re-configuration of the board. To override the default settings, simply select and close the desired jumper setting(s) and toggle the on-board manual reset button (S1) for the new setting(s) to take effect. The KSZ8851-16MLL-Eval jumper settings are defined in Table 3 below.

August 6, 2010 8/11 Rev. 1.1 KSZ8851-16MLL-Eval Evaluation Board User’s Guide Power Supply and Test Point Definition The KSZ8851-16MLL-Eval is supplied from external +5.0V DC power through a jumper (pin 1 and 3 at JP1), this +5.0V DC input is converted to both +3.3V with a Micrel LDO voltage regulator (U3, MIC5209BM) for VDD_A3.3 analog power and VDD (option for 3.3V, 2.5V or 1.8V) with a Micrel LDO voltage regulator (U5, MIC5209BM) for VDD_IO digital power. The KSZ8851-16MLL contains an internal +1.8V LDO, to provide its core, analog and PLL voltages. The KSZ8851-16MLL-Eval has four test points. They are defined in the following Table 4. Test Point Definition TP1 Power supply measurement for VDD_IO TP2 Power supply measurement for VDD_A3.3 TP3 1.8V digital core voltage output measurement from KSZ8851-16MLL internal LDO TP4 External power supply 5.0V_IN measurement Table 4. KSZ8851-16MLL-Eval Test Point Definition 4.3 RJ-45 Connector and Transformer The RJ-45 Jack (J1) connects to standard CAT-5 Ethernet cable to interface with 10BaseT/100Base-TX Ethernet devices. The LAN interface on the KSZ8851-16MLL is connected to a transformer (T1) with 50 ohm termination resistors for both TX+/- and RX+/- differential pairs. The line side of the transformer is connected to the RJ-45 connectors (J1). J1 also supports Auto-MDIX and Auto-Negotiation / Forced Modes. 4.4 EEPROM and LED Indicators It is optional in the KSZ8851-16MLL to use an external EEPROM. The EED_IO (JP2) must be pulled high (ON) to use external EEPROM. An external serial EEPROM with a standard microwire bus interface is used for non-volatile storage of information such as the host MAC address. The KSZ8851-16MLL can detect if the EEPROM is either a 1KB (93C46) or 4KB (93C66) EEPROM device. The EEPROM must be organized as 16-bit mode. The KSZ8851-16MLL EEPROM format is given in Table 5.
