...
(ED: Table with affected products should be final!)
Changes
#1 Changed DCDC MUN3CAD03-SE (U13, U15, U16, U19, U20, U23, U24, U29, U30, U31, U33 (variant dependent)) 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, U9, U12) from NT5AD256M16D4-HR (512 MByte) to K4A8G165WC-BITDTCV (1 GByte).
Type: Schematic Change
Reason: EOL of Component.
...
Reason: Improve voltage rail behaviour.
Impact: None.
#7 Added diode D2 between U41 pin 3 net MR and voltage rail 3.3VIN
...
.
Type: Schematic Change
Reason: Protect manual reset input signal.
Impact: None.
...
Reason: VTT layout and decoupling improvement.
Impact: Reliable Improved VTT voltage rail reliabililty.
#10 Added DCDC (U4) VCC supply option via resistors R132 (Default: not fitted) for voltage rail PL_DCIN and R133 (Default: fitted) for voltage rail 3.3VIN.
Type: Schematic Change
Reason: Efficiency improvement for DCDCEnable higher DCDC input voltage usage.
Impact: None. Dependent on used voltage at PL_DCIN the efficiency could be affectedOption for increased input voltage usage with available backward capability.
#11 Change current limit to approximately 14.5 A for DCDC MPQ8633BGLE-Z (U4) via changing resistor R92 from 4.22 kOhm to 9.09 kOhm.
...
Reason: Fixed wrong resistor value.
Impact: None.
#12 Added option to use remote senses for DCDCs U30 via resistor R134, U29 via resistor R135 and U31 via resistor R136. These options are not used in default variants.
Type: Schematic Change
Reason: Remote sense option.
Impact: None.
#12a Added option to use remote senses for DCDCs U30 via resistor R134, U29 via resistor R135 and U31 via resistor R136. These options are not used in default variants.
Type: Schematic Change
Reason: Remote sense option.
Impact: None.
#12b Added option to use remote senses for DCDCs U30 via resistor R134, U29 via resistor R135 and U31 via resistor R136. These options are not used in default variants.
Type: Schematic Change
Reason: Remote sense option.
