There are differences between datasheet "dlpz004a.pdf" and Logic's Schematic regarding Table9-1 terminal interconnection.
Which is correct?
RSVD_G5 (A18) LED drive NC
RSVD_G6 (A19) LED drive NC
RSVD_S0 (AA24) Pull-up & Pull-down NC
RSVD_S1 (AG14) Pull-up & Pull-down Connect to DGND
RSVD_S2 (AG15) Pull-up & Pull-down Connect to DGND
RSVD_S3 (AH14) Pull-up & Pull-down Connect to DGND
RSVD_S4 (AH26) Pull-up & Pull-down NC
RSVD_S18 (U23) Pull-up & Pull-down NC
RSVD_S19 (U24) Pull-up & Pull-down NC
RSVD_S20 (Y27) Pull-up & Pull-down Connect to DGND
RSVD_S21 (Y28) Pull-up & Pull-down Connect to DGND
RSVD_X11 (AH15) NC Connect to DGND
RSVD_X12 (U8) Pull-down NC
RSVD_X13 (U7) Pull-up NC
RSVD_X14 (AB17) Pull-down NC
RSVD_X15 (AA17) Pull-up NC
For these pins you can stick to the datasheet for all of this.
The pins don't have any associated functinality inside the chip. So follow the recommendation as in the data sheet. If it NC - leave it floating and where ever it DGND then connect to ground.
As per Sanjeev's advice please follow the datasheet for these signals.
However I would like to also clear up a little confusion about the schematic for the following signals. The latest schematic shows:
RSVD_S0 (AA24) Pull-down only
RSVD_S1 (AG14) Pull-up only (Pull-down is shown as DNI - Do Not Install)
RSVD_S2 (AG15) Pull-up only (Pull-down is shown as DNI - Do Not Install)
RSVD_S3 (AH14) Pull-up only (Pull-down is shown as DNI - Do Not Install)
RSVD_S4 (AH26) Pull-up only
RSVD_S18 (U23) Pull-up only
RSVD_S19 (U24) Pull-up only
RSVD_S20 (Y27) Pull-up only
RSVD_S21 (Y28) Pull-up only (Pull-down is shown as DNI - Do Not Install)
I hope this helps.
Thank you for your answer.
There are contradiction between datasheet and your answer.
For example, in dataseet RSVD_S0 is NC, but your answer is Pull-down only.
I am confused.
Following to datasheet is correct?
I think you should you refer to schematic.
because the pins you mention are "RESERVED FOR FUTURE USE" or " Unused input only" in datasheet, but those pins have been used actually in schematic,
so should refer to schematic.
Hi Long and Keisuke,
As i said earlier altough the pins shown being used in the Schemaitc they it is not performing any functionality inside the chip. Suggestion is to follow the Datasheet guidelines.
Let me know if you there any questions regarding this.
