Impact: None. If custom CPLD design used, check for compatibility.

#13 Power supervisor U23 connected to 3.3VIN power rail (was 3.3V).

Type: Schematic Change

Reason: Avoid high-signal-state at U23 manual reset pin 3 without powered supervisor.

Impact: None.

#14 Added protection diode D5 to U23.3 (#MR input).

Type: Schematic Change

Reason: Avoid voltage high-signal-state at U23 manual reset pin 3 without powered supervisor.

Impact: None.

#15 Changed PCB layout of power supplies.

Type: PCB Change

Reason: DCDCs with new footprints needs to be used.

Impact: None.

#18  Changed PCB layout of Samtec B2B signals.

Type: PCB Change

Reason: Result of this PCN changes.

Impact: The length of the tracks has been changed. Pinout of Samtec B2B connectors is not affected. Changed trace length has to be taken into account in existing designs. The trace length for new revision are added to the 4x5 series pinout generator.  Please, check if change in trace length still matches your requirements. Adaption of carrier may be necessary.

#20 Added legal notices.

Type: DOC Change

Reason: Clarify copyright issues.

Impact: None. Schematic page number changes.

#22 Added system overview.

Type: DOC Change

Reason: Display system information.

Impact: None. Schematic page number changes.

#23 Added power diagram.

Type: DOC Change
