Differences in pinout of TMS570LS3137 comparing Eval Schematics and Datasheet

Other Parts Discussed in Thread: TMS570LS3137

Dear Sirs, I'm a disty FAE, one of our customers is going to realize schematics for an application that will mount TMS5703137BZWT.

Customer noticed differences among the pinouts reported on datasheets and the schematics of this device.
As an example: EMIF_DATA[6] is G4 on the HDK schematic and G5 on the datasheet.
The same un-congruences for the entire bus.
Documents found at these links:
http://www.ti.com/lit/ds/symlink/tms570ls3137.pdf
http://processors.wiki.ti.com/images/5/5b/TMS570LS31_HDK_Schematics.pdf

The same as for the TMS570LS31x_CNCD_Schematic.pdf where the EMIF_DATA[0] is K16 on the board and K15 on the datasheet.

Which is the correct pin_out? That on the datasheet or that on the EVB schematics?

Best Regards

Hello Enrico,

Here is the resolution:

1. In the datasheet, G4 is a NC (no connect), and G5 has the EMIF_DATA[6] functionality. The schematic has same functionality on both G4 and G5, but G4 should be a NC.

2. Same for EMIF_DATA[0], K16 is a NC. K15 on both schematic and datasheet consistently show EMIF_DATA[0] functionality.

So the datasheet is ok but on the orcad symbol used on EVB schematics there are some replied names used for the pins.

Seems to be a little confusing isn't it?

Enrico

Enrico,

Agreed and we have made note of that. Thanks!
