Changes
#1 Changed LPDDR4 (U6) from IS43LQ32256A-062BLI to IS43LQ32256B-062BLI.
Type: BOM Change
Reason: Component not recommended for new designs.
Impact: None, die revision changed. Trenz reference design reflects the changes.
#2 Changed signal trace lengths.
Type: PCB Change
Reason: Updated PolarFire SoC internal trace length and improved LPDDR4 length matching.
Impact: Improved LPDDR4 behaviour. Changed trace length have to be taken into account in existing designs. The trace length for new revision will be available in TEM0007 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
#3 Changed flash (U3) from MT25QU512ABB8E12-0SIT to MX25U51245GXDI00.
Type: BOM Change
Reason: EOL of Component.
Impact: None, no changes in our reference design expected to be necessary.
#4 Changed DCDC (U18) from MIC33153YHJ-TR to MPM3834CGPA and adapted power circuit.
Type: Schematic Change
Reason: Increase output current capability.
Impact: None. Increased output current capability from 1.2 A to 3 A. Minor changes in electrical characteristics.
#5 Changed inductor (L8) from SRP0320-R47K to XGL4030-471MEC.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Minor changes in electrical characteristics.
#6 Added capacitors (C83, C85, C94).
Type: Schematic Change
Reason: Improve power supply rail.
Impact: Improved power supply rail.
#7 Changed all 220 nF, 0201, 6.3 V capacitors from X5R to X6S.
Type: BOM Change
Reason: Improve temperature range.
Impact: None, capacitors have slightly larger capacitance variation.
#8 Changed all 4.7 µF, 0402, 6.3 V capacitors from X5R to X6S.
Type: BOM Change
Reason: Improve temperature range.
Impact: None, capacitors have slightly larger capacitance variation.
#9 Changed all 10 µF, 0603, 16 V capacitors from X5R to X6S.
Type: BOM Change
Reason: Improve temperature range.
Impact: None, capacitors have slightly larger capacitance variation.
#10 Changed all 22 µF, 0603, 10 V capacitors from X5R to X6S.
Type: BOM Change
Reason: Improve temperature range.
Impact: None, capacitors have slightly larger capacitance variation.
#11 Added test points (TP16 ... TP32).
Type: Schematic Change
Reason: Improve measuring process.
Impact: None. Improved measuring process.
#12 Moved test points (TP3, TP6, TP8, TP9, TP11, ... , TP15) on bottom layer.
Type: PCB Change
Reason: Result from other changes above.
Impact: Test points have different location on board.
#13 Added RoHS and WEEE logo.
Type: PCB Change
Reason: Improve product classification identification.
Impact: None.
Method of Identification
The revision number is shown on the top side of the PCB.
