2.3.1 Programming Procedure

This section describes NVM programming through third-party tools. This procedure is completed automatically during import and export of Project files from Fusion Digital Power Designer.

Configure User-Programmable Parameters (one-time only)

  1. Set all of the user-accessible parameters via the standard PMBus, and Manufacturer Specific commands, using Fusion Digital Power Designer or the Technical Reference Manual for the device.
  2. Issue the STORE_DEFAULT_ALL command. This command commits these values to NVM, and updates the checksum value.
  3. Wait approximately 100 ms.
  4. Write PAGE to 00h.
  5. Read-back and Record the value of IC_DEVICE_ID and IC_DEVICE_REV commands
  6. Read-back and Record the value of the USER_DATA_00 through USER_DATA_12 commands
  7. Read-back and Record the value of the MFR_SERIAL command
  8. Read-back and Record the value of VOUT_MAX
  9. Write PAGE to 01h
  10. Read-back and Record the value of VOUT_MAX

Program and Verify NVM (repeat for each device)

  1. Apply 3.3 V to the V3P3 pin to start the device. Make sure to disable power conversion for NVM programming.
  2. Read-back and verify that IC_DEVICE_ID and IC_DEVICE_REV values match those recorded previously. This verification ensures that user-parameters being programmed correspond to the same device/revision as previously configured.
  3. Write PAGE to 00h.
  4. Write the USER_DATA_00 through USER_DATA_12 commands, with the values recorded previously.
  5. Write VOUT_MAX (Page 0) with the value recorded previously.
  6. Write PAGE to 01h
  7. Write VOUT_MAX (Page 1) with the value recorded previously.
  8. Issue STORE_DEFAULT_ALL.
  9. Wait approximately 100 ms.
  10. Read-back the MFR_SERIAL command, and compare the value to that recorded previously. If the new MFR_SERIAL matches the value recorded previously, the software has successfully programmed the NVM.
