Changes
#1 Changed DCDC EN5311QI (U2, U3) to MPM3834CGPA and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
#2 Changed ferrid bead BKP0603HS121-T (L1, L2, L4, L5) to MPZ0603S121HT000.
Type: Schematic Change
Reason: EOL of Component.
Impact: None.
#3
...
Set proximity/ambient light sensor Si1143-A11-GMR (U4) and
...
circuit components (D1, D3, D5, R6,
...
and R20) to not fitted.
Type: Schematic Change
Reason: EOL of Component.
Impact: Sensor is no longer available. Firmware reflects it but custom firmware Custom design needs to be updated by customer.
#4 Added resistors (R37, R38, R39) assembly option to prepare proximity/ambient light sensor (U4) circuit for Si115x usage.
Type: Schematic Change
Reason: EOL of Si1143-A11-GMR.
Impact: Si115x could be assembled.
#5 Changed MEMS oscillator (U8) from SiT8008AI-73-XXS-33.
...
333333E to SiT8008BI-73-XXS-33.333333E.
Type: BOM change
Reason: EOL of Component.
Impact: None. Clock revision changed.
...
#6 Added jumper (J4) and resistor (R40) to enable JTAG only boot mode and changed resistor (R11) from 19.1 kOhm to 10 kOHm.
Type: Schematic Change
Reason: QSPI programming problems with newer Vivado versions.
Impact: None. Fix QSPI programming problems with newer Vivado versions according to AR#00002 - QSPI Programming issues.
#7 Renamed signal name from "SPI-DQ0/M0" to "SPI-DQ0/M3".
Type: Schematic Change
Reason: Use AMD boot mode name convention.
Impact: None.
#8 Renamed signal name from "SPI-DQ3/M3" to "SPI-DQ3/M0".
Type: Schematic Change
Reason: Use AMD boot mode name convention.
Impact: None.
#9 Modified testpoints : Added (TP4, TP5
...
) / Changed size from 1 mm to 0.8 mm diameter (TP1, TP2, TP3, TP7
...
, TP8).
Type: PCB Change
Reason: Use standard testpoints.
Impact: None.
...
#10 Modified fiducials: Added (PM5, PM6) / Changed (PM1, PM2, PM3, PM4).
Type: PCB Change
Reason: Use standard fiducial setting.
Impact: None.
...
#11 Added CE and UKCA logo.
Type: PCB Change
Reason: Requiered Required logos.
Impact: None.
...
#12 Added legal notices, revision history, block and power diagram. Updated page count and order.
Type: Documentation Update
...
Impact: None.
