Changes
#1 Changed DCDC EN6347QI (U7) to MPM3860GQW-Z and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#2 Changed DCDC EP53A7HQI (U6) to MPM3834CGPA-Z and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Minor changes in electrical characteristics.
#3 Changed B2B connection signals.
- Connected B2B connector J11 pin 119 from signal "BUTTON" to "LED2".
- Connected B2B connector J11 pin 121 from signal "LED2" to "BUTTON".
Type: Schematic Change
Reason: Improve signal funtionality in different modes.
Impact: Customer design for module needs to be adapted by customer in cases where these signals are used.
#4 Changed USB input protection diode (U2) position.
Type: Schematic Change
Reason: Improve USB input protection.
Impact: None. Minor changes in electrical characteristics.
#5 Changed MEMS oscillator (U4) from SiT8008AI-73-XXS-12.000000E to SiT8008BI-73-XXS-12.000000E.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Clock revision changed.
#6 Changed protection diodes (D6, D7) from WE-TVS-824013 to WE-TVS-824015043.
Type: PCB Change
Reason: EOL of Component.
Impact: None. Minor changes in electrical characteristics.
#7 Changed ferrid bead (L3) from BKP0603HS121-T to MPZ1608S221A.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Minor changes in electrical characteristics.
#8 Moved CRUVI mounting holes and CRUVI connectors (J5 ... J8) 0.6 mm closer to module.
Type: PCB Change
Reason: Improve CRUVI module handling.
Impact: In cases where board is used within a system assembly changes could be needed.
#9 Moved mounting holes and connector for TEM0005 module 1.6 mm closer to the edge.
Type: PCB Change
Reason: Increase space between module and CRUVI boards.
Impact: In cases where board is used within a system assembly changes could be needed.
#10 Moved right side mounting holes 16.6 mm closer to CRUVI connectors.
Type: PCB Change
Reason: Improve CRUVI module handling via aligning mounting holes and CRUVI mounting holes.
Impact: In cases where board is used within a system assembly changes could be needed.
#11 Added pull-up resistor (R37) assembly option (default: not assembled).
Type: Schematic Change
Reason: Allow changed FTDI programming method released by AMD with Tool Version 2022.2 and newer (UG980 - Chapter: Programming FTDI Devices for Vivado Hardware Manager Support) to be used.
Impact: None.
#12 Changed resistor (R8) from 49.9 Ohm, 0.063 W, 0402 to 33 Ohm, 0.05 W, 0201.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#13 Changed resistor (R9) from 10 kOhm to 12 kOhm.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#14 Changed 100 nF capacitor (C1, C2) from 6.3 V, 0201 to 25 V, 0402.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#15 Changed capacitor (C32) from 4.7 µF, 6.3 V, 20 %, 0402 to 10 µF, 10 V, 10 %, 0805.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#16 Changed capacitor (C33) from 470 nF, 6.3 V, 20 %, 0201 to 100 nF, 25 V, 10 %, 0402.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Minor changes in electrical characteristics.
#17 Added testpoints (TP7 ... TP12).
Type: PCB Change
Reason: Improve voltage and signal monitoring.
Impact: None.
#18 Added UKCA-, RoHS- and ESD-logo.
Type: PCB Change
Reason: Improve product classification identification.
Impact: None.
