SmartFusion2 DMPM Kit
Quickstart Guide
Overview
Microsemi's SmartFusion
SmartFusion DMPM kit by utilizing SmartFusion2 FPGA's ability to manage up to 64 channels of both analog and
digital point-of-loads. The SF2-DMPM Daughter Board provides a bench top demonstration and development platform
for Microsemi's SmartFusion2 MPM reference design, which incorporates eight digital regulators (controlled and
monitored through the PMBus) in addition to eight Microsemi analog regulators, which are monitored through an
external ADC. It includes a PMBus header for I
module. The SF2-DMPM-KIT connects to the SF2-DEV-KIT through the FMC header.

  • Page 3: Installation

    Run the installer and follow the installation wizard instructions. By default, the MPM installs into the C:\Microsemi\SF2_MPM_RefDesign_v6.1 folder and this is the recommended location for it. In particular, avoid installing it in a folder that is very deeply nested or has a very long path name. Otherwise, some tools may encounter problems accessing files with names longer than 259 characters*.
  • Page 4 SmartFusion2 Development Kit Setup The following jumper settings are required on the SmartFusion2 Dev-Kit to route the signals required for the DMPM board to the FMC connector. Due to the number of jumpers needed, we have provided pictures of the jumpers as well as the list of pins.

  • Page 6 Using the MPM Figure 5 • SF2-DMPM-DB l C Jumpers JP23 should have pins 1 and 2 jumpered and J24 should be jumpered to provide 3.3 V and 2.5 V supplies to the SF2- DMPM-DB board from the FMC connector. J22 should have 7 x 3 jumpers installed as shown in Figure 5 above, to link the eight DPOLs to PMBUS1.

  • Page 8 Using the MPM The MPM Reference Design Demo Without the MPM GUI Once the MPM reference design has been programmed to the target hardware, the demo can be viewed even without the MPM GUI by using SW3 on the Dev-Kit to initiate power-up and power-down sequences and observing the current state of the MPM on the Dev-Kit LEDs.
  • Page 9 Table 4 • MPM Status Description Status Description Stopped Power-off sequencing is successful and the MPM is idle. None of the following are active: channel threshold monitoring, output flag generation, and open or closed trimming. The channel voltages can be read in any state.
  • Page 10 Using the MPM If you press SW3 to initiate power-up sequencing, the MPM state changes to Starting and you can see the various regulator enabled LEDs on the SF2-DMPM-DB turning on in sequence. If the status does not change to Started and the power-on sequence restarts, you can adjust the voltage of the individual APOL channels via the associated potentiometers to complete the sequencing.
  • Page 11 Use the included standard USB A/B cable to connect the USB-ISS to your PC. Install the drivers that are bundled with the MPM GUI in the C:\Microsemi\SF2_MPM_RefDesign_v6.1\Devantech_USB-ISS_drivers folder. After installing the drivers, and plugging the USB-ISS module into a spare USB port, find which COM port it has been assigned to.
