Changes
#1 Changed DCDC (U4, U9, U12, U13, U15, U20, U24, U26, U27) from MUN3CAD03-SE to TPS82085SIL and adapted voltage divider resistors.
Type: BOM Change
Reason: TPS82085SIL availability.
Impact: Minor changes in electrical characteristics.
#2 Changed DDR4 SDRAM (U2, U3) from K4A8G165WB-BIRC to K4A8G165WC-BITDTCV.
Type: BOM change
Reason: BOM Optimization.
Impact: New DDR timings may be considered in designs. DDR4 setup used in reference design is known to work still.
Method of Identification
Locate DDR4 SDRAM (U2) on top side of TE0820-05 PCB:
| old | new |
|---|---|
