Reason: Enpirion DCDCs are discontinued.
Impact: None.
Type: Schematic Change
Reason: Supply chain optimization.
Impact: None.
Type: Schematic Change
Reason: Supply chain optimization.
Impact: None.
Type: Schematic Change
Reason: Improved voltage rail supervision.
Impact: None. More power rails are now monitored.
Type: Schematic Change
Reason: Avoid voltage high-signal-state at U23 manual reset pin 3 without powered supervisor.
Impact: None.
Type: Schematic Change
Reason: Avoid high-signal-state at U23 manual reset pin 3 without powered supervisor.
Impact: None.
Type: Schematic Change
Reason: Set reset threshold for U26 to 0.905 V.
Impact: None. Improved reset behaviour.
Type: Schematic Change
Reason: Power supervisor connection.
Impact: None. If custom CPLD design used, check for compatibility.
Type: Schematic Change
Reason: Enable boundary scan for MIO bank 1.
Impact: None. If custom CPLD design used, check for compatibility.
Type: Schematic Change
Reason: Monitor or set POR-signal.
Impact: None. If custom CPLD design used, check for compatibility.
Type: Schematic Change
Reason: Revision indicator via pins.
Impact: None.
Type: Schematic Change
Reason: Xilinx recommendation.
Impact: None.
Type: Schematic Change
Reason: Ferrite beads are discontinued.
Impact: None.
Type: Schematic Change
Reason: Decoupling improvement for "1V" voltage rail.
Impact: None.
Type: Schematic Change
Reason: Xilinx decoupling recommendation.
Impact: None. Designator changed.
Type: Schematic Change
Reason: Decoupling improvement for "1V" voltage rail.
Impact: None.
Type: Schematic Change
Reason: Decoupling improvement for VCCPLL.
Impact: None.
Type: Schematic Change
Reason: Decoupling improvement for VCCAUX and VCCPAUX.
Impact: None.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
Type: Schematic Change
Reason: Decoupling improvement for VCCPLL.
Impact: None.
Type: Schematic Change
Reason: Decoupling improvement for VCCBRAM.
Impact: None.
Type: Schematic Change
Reason: Decoupling improvement for VDDQSNS and VDD.
Impact: None.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Physical dimension changed.
Type: SCH and PCB Change
Reason: Improve production yield.
Impact: None.
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.
Type: DOC Change
Reason: Documentation optimization.
Impact: None. B2B information, legal notices, revision history, system overview, and power diagram are inserted or changed. Schematic page number changes.
The model code and revision number of the module "TE0715-04" and "TE0715-05" are printed on the top side of the PCB for revision 04 and 05.
The new revision 05 will be shipped from November 2022. If the new revision is not suitable for your application and still the former revision of the board is needed, please contact us.
