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 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.

- Page 3 Power Manager II Hercules Development Kit Power Manager II Hercules Demos: • Default State – With demo DIP switches set as shown (all 0’s) the LCD will cycle through its self- test sequence along with the PLD output LEDs. This is the default (shipped) turn-on condition. • Demo 1: Switching Power Supply Trim – The Power Manager II Trim-DAC output trims the 1.2V supply to better than 1% of its factory set value. This is done by the ispPAC -POWR1220AT8 ® and MachXO™ using an external closed loop trim to adjust the feedback into the regulator trim pin. The LCD displays the output voltage of the 1.2V switching regulator at VMON1 using the ADC in the POWR1220AT8. Pressing and holding down the mode (SW3) switch changes the trim mode from closed loop to open loop. In this mode, the Trim-DAC output is set to a fixed (stored) digital value which is selected by the Voltage Profile Select pins of the Power Manager II. • Demo 2: Power Supply Margin Down – With demo DIP switches set as shown, the supply is trimmed to -7.5% of its factory value (1.2V - 0.09V = 1.11V) using closed loop trim. VMON1 is chosen to measure the 1.2V DC-DC power supply and the value is read by the POWR1220AT8 ADC and displayed on the LCD. Pressing the mode switch results in the trim mode switching from closed loop to open loop trim. This means the output is set to a fixed (stored) digital value and will not be as accurate as closed loop trim.
