Power Manager II Hercules Development Kit This document provides a brief introduction and instructions to install and run the Power Manager II Hercules Standard and Advanced Development Kits on Windows 7/Vista/XP. More documentation can be downloaded from www.latticesemi.com/herculesdevkit. Check Kit Contents The Power Manager II Hercules Development Kit contains the following items: • Power Manager II Hercules Evaluation Board pre-loaded with Hercules support demos • USB connector cable • 12V DC wall adapter power supply • QuickSTART Guide Static electricity can shorten the lifespan of electronic components. Please handle the kit components carefully. Powering the Evaluation Board Running the pre-loaded demonstration does not require connecting the provided USB cable to a PC. The USB cable is required to modify the pre-loaded demo, interface to advanced demos, or load pre-configured designs. Do not plug the USB cable into the PC until after loading Lattice’s USB drivers (included with ispVM).  The default operating system drivers are not compatible with Lattice programming tools.

In the following steps, the evaluation board will be powered and made ready to run the pre-loaded demonstrations. Verify the jumpers J5 (VMON7) and J6 (VMON8) select the “12V_OR” option and not the “cPCI_HS” option. 1. Connect the AC adapter from a wall outlet to the power socket. After a connection is made to the 12V wall adapter plug, the green PWR_3.3V interface LED (D14) will light up indicating the onboard 3.3V regulator (U1) is operational. The Power Manager II will next illuminate three supply status LEDs: 12V_HS, 1.2V_SEQ, and PWR_GOOD (D1, D2, and D7). The TDO (D12) and data (D8 through D11) LEDs may also light up. Run the Demonstrations This step describes the functionality of the pre-configured Power Manager II Hercules demos: voltage supply trimming, supply margining, voltage monitoring, fault monitoring and logging. Operation of the pre-loaded demos is accomplished by setting the demo DIP switches and pressing the mode switch (SW3). The following tables summarize the demo and switch settings pertaining to each of the pre-loaded demos.
