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 Lattices 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 on- board 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. Demo DIP Switch Setting SW3 Mode VMON Up=1 7 6 5 4 3 2 1 0 Demo Pressed=0 Comment Default n/a 0 0 0 0 0 0 0 0 LCD self-test Trim 1.2V to <1% error SW3 = trim mode 1 1=CLT, 0=OLT 0 0 0 0 0 0 0 1 VMON1/LCD = Measured supply voltage Margin 1.2V down 7.5% SW3 = trim mode 2 1=CLT, 0=OLT 0 0 0 1 0 0 0 1 VMON1/LCD = Measured supply voltage Margin 1.2V up 7.5% SW3 = trim mode 2a 1=CLT, 0 =OLT 0 0 1 0 0 0 0 1 VMON1/LCD = Measured supply voltage 12V HS voltage 3 n/a 0 0 0 0 1 0 1 1 VMON11/LCD = Measured supply voltage Fault monitoring of slide potentiometer voltage (Vpot) 4 n/a 0 0 0 0 1 0 0 1 VMON9/LCD = Measured Vpot voltage (0V to 3.3V) 1=Display LCD = Total count of faults logged 4a 1 x x x x x x x 0=Clear All Press SW3 to reset count to zero Demo DIP Switch Setting SW3 Mode VID Default=1 7 6 5 4 3 2 1 0 Demo Pressed=0 Comment Add VID (DIP 0-3) value to 1.2V supply voltage VID (v8, v4, v2, v1) is a binary value multiplied by 10mV 5 1=Hold, 0=Update 0 1 1 1 v8 v4 v2 v1 For example: 0000b=0*10mV=0V, 0100b=4*10mV=40mV, 1000b=810mV=80mV 1100b=12*10mV=120mV VMON1/LCD=Measured supply voltage Subtract VID (DIP 0-3) value to 1.2V supply voltage 5a 1=Hold, 0=Update 0 1 1 0 v8 v4 v2 v1 VID (v8, v4, v2, v1) is a binary value multiplied by 10mV VMON1/LCD=Measured supply voltage 5b 1=Hold, 0=Update 0 1 0 x x x x x Turn off 1.2V supply VMON1=LCD Notes: 1. The mode switch (SW3) is equal to a logic one (1) when not pressed. Pressing the mode switch (SW3) enters a logic zero (0). 2. The demo DIP switches (SW5) are equal to a logic ones (1) when up. Placing the switches down makes them zeros (0). 3. CLT means closed loop trimming mode (supply setpoint is trimmed to an accurate value). OLT means open loop trim to prede- termined value (supply setpoint is a preset voltage and not trimmed). In other words, Demos 1 and 2 use either CLT or OLT trim mode depending on the condition of the mode switch (SW3). 4. Pressing the PLD reset switch (SW4) resets the LatticeMico8 controller in the MachXO (U4), not the POWR1220AT8 (U3). 5. The position of Interface Select Switches (SW2) does not affect any of the testing in the QuickSTART guide.
