Type: BOM Change
Reason: TPS82085SIL availability.
Impact: Minor changes in electrical characteristics.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Custom system controller firmware needs to be adapted if system controller (U2) pin 20 is used inside the firmware because pin functionality changes.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Minor changes in electrical characteristics.
Type: Schematic change
Reason: Optional MP8869SGL-Z I2C monitoring.
Impact: None. Consider possibly I2C address conflicts before connecting DCDC (U4) to I2C bus.
Type: BOM change
Reason: Functionality change for capacitor C108 and BOM optimization.
Impact: None.
Type: Schematic Change
Reason: Protect manual reset pin.
Impact: None.
Type: Schematic Change
Reason: Current limitation between different voltage regions.
Impact: None.
Type: Schematic Change
Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up if necessary.
Impact: None.
Type: Schematic Change
Reason: Use new clock revision.
Impact: None.
Type: Schematic Change
Reason: Voltage supervision improvement.
Impact: None.
Type: Schematic Change
Reason: Power management improvement.
Impact: None.
Type: Schematic Change
Reason: Power management improvement.
Impact: None. Refer to change #13.
