Changes
#1 Changed DDR3L SDRAM (U12) from
...
IM4G08D3FABG-125 to IS43TR85120BL-125KBLI.
...
Type: BOM change
Reason: Old DDR was not specified for industrial temperature range.
Impact:
...
New timings may be considered for existing designs.
#2 Changed DCDC EN6347QI (U1) to MPM3860GQW-Z and adapted power circuit.
Type: Schematic Change
Reason: BOM OptimizationEOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#3 Changed
...
DCDC EN5311QI (U10, U11) to MPM3834CGPA and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#4 Changed load switch from TPS27082LDDCR (Q1) to MP5077GG-Z and adapted circuit.
Type: Schematic Change
Reason: Use new clock revisionBOM Optimization.
Impact: None.
...
Increased current output capability. Minor changes in electrical characteristics.
#5 Changed power supervisor TPS3805H33DCKR (U23) to STM6710LWB6F and adapted circuits.
Type: Schematic Change
Reason: Improved power monitoring.
Impact: Improved power monitoring circuit by supervising additional voltage rails. If monitored voltages are out of range signal "PG_ALL" is triggered.
...
#6 Improved voltage rail VTT decoupling via adding capacitors C135...
...
C138.
Type: Schematic Change
Reason: EOL of ComponentVTT decoupling improvement.
Impact: NoneImproved VTT voltage rail reliabililty.
...
#7 Changed
...
clock (
...
U9) from SiT8008AI-73-XXS-25.000000E to SiT8008BI-73-XXS-25.000000E.
Type: Schematic Change
Reason: EOL of ComponentUse new clock revision.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
...
#8 Changed ferrid bead BKP0603HS121-T (L1...L6) to MPZ0603S121HT000.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
...
#9 Added diode D4 between signal nets "INIT" and "PROG_B".
Type: Schematic Change
Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up.
Impact: None.
...
#10 Added pull-up resistor R50 for signal net "PROG_B".
Type: Schematic Change
Reason: Remove floating signal situations and enable signal measurement.
Impact: None. Firmware reflects it but custom firmware needs to be updated by customer.
...
#11 Added testpoints TP1...
...
TP28.
Type: Schematic Change
Reason: Improve voltage measuring possibilities.
Impact: None.
...
#12 Changed size from 0805 to 0603 for capacitor C44.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
...

Type: Schematic Change
Reason: Use standard fiducials.
Impact: None.
#14 Added UKCA logo.
Type: PCB Change
Reason: Required for export to UK.
Impact: None.
...
#15 Updated components from library.
Type: Schematic Change
Reason: Use latest component data.
Impact: None.
