Changes
#1 Replace EN6347QI (U1) by MPM3840GQV-Z
Type: Schematic Change
Reason: Enpirion DCDCs are discontinued.
Impact: None.
#2 Replace TPS82085SIL (U2, U3, U8, U24) by MPM3834CGPA
Type: Schematic Change
Reason: Availability for Texas Instrument DCDCs is not good.
Impact: None.
#3 Replace TPS27082LDDCR (Q1) by MP5077GG-Z
Type: Schematic Change
Reason: Part availability is not good.
Impact: None.
#7 Added power supervisor BD39040MUF (U25)
Type: Schematic Change
Reason: Improved voltage rail supervision.
Impact: None. All power rails are now monitored.
#8 Changed net name "PG_DDR_PWR" to "PG_All" and connect BD39040MUF "PG_All" - signal U25.15 to system controller U26.27 with pull-up resistor R67.
Type: Schematic Change
Reason: Power Supervisor connection.
Impact: None. If custom CPLD design used, check for compatibility.
#10 Signal MIO8 (U5.E18) connected to system controller (U26.8).
Type: Schematic Change
Reason: Enable boundary scan for MIO bank 1.
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.
#15 LIB update
Type: SCH and PCB Change
Reason: Update schematic symbols and footprints to latest version.
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
Reason: Display power supply information.
Impact: None. Schematic page number changes.
Method of Identification
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.
Production Shipment Schedule
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.
