Impact: None. Minor changes in electrical characteristics.

...

#3 Added I2C connection between MP8869SGL-Z (U4) and system controller (U18) pins D11 (signal "I2C1_SCL") and C13 (signal "I2C1_SDA").

Type: Schematic Change

Reason: Improve MP8869SGL-Z handling.

Impact: System None. Custom system controller firmware needs to be adapted if system controller (U18) pin D11 is used inside the firmware because system controller (U18) pin D11 was used as power good signal (PG_VTT) for EV1320QI (U9) as detailed in change #6#7.

#7 Changed system controller (U18) pin D11 from DCDC EV1320QI (U9) signal PG_VTT to new added I2C interface signal I2C1_SCL.

Type: Schematic Change

Reason: EOL of EV1320QI.

Impact: System None. Custom system controller firmware needs to be adapted as discussed in change #2#3.

...

#8 Changed DCDC EP53A8HQI (U10, U11) to MPM3834CGPA and adapted power circuit.

Impact: None. Minor changes in electrical characteristics.

...

#9 Added transistor (T8) to MPM3834CGPA (U11) feedback circuit to optionally select different output voltages (1.8 V / 2.5 V / 3.0 V).

Type: Schematic Change

Reason: EOL of EP53A8HQI.

Impact: None. Minor changes in electrical characteristics.

...

#10 Added MPM3834CGPA (U11) power good signal "PG_VADJ" to system controller (U18) pin G10.

Type: Schematic Change

Reason: Improve power handling.

Impact: None. System Custom system controller firmware could be changed to use this signal.

...

#11 Changed system controller (U18) pin F13 from signal VADJ_VS2 to not connected.

Type: Schematic Change

Reason: EOL of EP53A8HQI.

Impact: System None. Custom system controller firmware needs to be adapted.

...

#12 Changed NC7WZ16P6X (U16) to SN74AUP2G17DCKR.

Type: Schematic Change

Reason: Not recommended for new design of component.

Impact: None. Minor changes in electrical characteristics.

...

#14 Added optional MEMS LVDS Oscillators (Y2, Y3, Y4, Y5).

Type: Schematic Change

Reason: BOM Optimization.

Impact: None. Minor changes in electrical characteristics.

...

#15 Removed voltage divider resistors for DDR3 SDRAM (U12, U13) reference voltages.

Type: Schematic Change

Reason: BOM Optimization.

Impact: None. Minor changes in electrical characteristics.

...

#16 Added resistor options for REFCLK_EMIF clock (signals "REFCLK_EMIF_P"/"REFCLK_EMIF_N") for common mode voltage setting.

Type: Schematic Change

Reason: Optionally common mode voltage setting.

Impact: None. Minor changes in electrical characteristics.

...

#17 Changed I2C bus connection for CryptoAuthentication Device (U19) from 1.8 V bus "I2C" to 3.3 V bus "I2C1".

Type: Schematic Change

Reason: Simplify power handling.

Impact: Firmwares None. Custom firmwares with CryptoAuthentication Device (U19) usage needs to be adapted.

...
