3.3.1 Board and Connector Description

  1. First 40-pin socket. Place DUT #1 in this socket, with pin 1 in the corner marked with a yellow star symbol.
  2. 10-pin keyed connector for TI USB-to-GPIO adapter.
  3. 2-pin connector (J2) for external 3.3V power supply
  4. 3-position switch (S1). Determines whether the 3.3V power supply is sourced from external connector (J2):
    • Left position: sources 3.3-V power supply from PMBus adapter
    • Middle position: disconnected 3.3-V power
    • Right position: sources 3.3-V power supply from J2
  5. 2-position switch (test mode selector). Switches between manual power-on and power-off (using S 2), or automatic control.
    • Left position. Automatic control. PMBus CNTL pin controls 3.3-V power applied to DUT #1 and DUT #2.
    • “Right position. Manual control. Switch S2 controls 3.3-V power applied to DUT #1 and DUT #2.
    a.. b.
  6. Multiple board male connector (J1). Use J1 and J7 to mate multiple programming boards in series.
  7. 2-position switch (S2). Toggles power applied to the socketed devices, when manual power control is selected using the test mode selector switch.
    • Up position: power is applied to DUTs (only in Manual mode) .
    • Down position: Power is not applied to DUTs (only in Manual mode).
  8. Second 40-pin socket. Place DUT #2 in this socket, with pin 1 in the corner marked with a yellow star symbol.
  9. VREF2_ON. LED illuminates when DUT#2 successfully powers up ( VREF voltage increased to approximately 1.7 V)
  10. Address selection for DUT#2. Changing the jumper position according to the table printed on the silkscreen of the board changes the PMBus address that DUT#2 responds to.
  11. Multiple board female connector (J7). Use J1 and J7 to mate multiple programming boards in series.
  12. VREF1_ON. LED illuminates when DUT#2 successfully powers up ( VREF voltage increased to approximately 1.7 V)
