Products Affected

This change affects all variations of TE0703 carrier of revision: TE0703-05

Changes

#1  Changed micro SD card connector (J3)

Type: BOM change

Reason: Demand for industrial temperature range

Impact: Specified for industrial temperature range

#2 Changed push button (S1)

Type: BOM change

Reason: Demand for industrial temperature range

Impact: Specified for industrial temperature range

#3 Replaced input power protection

Type:  Optimization

Reason: Cost savings

Impact: None

#4 Added jumper (J11) to select SD level shifter voltage on FPGA side

Type: Schematic change

Reason: Modules have 1.8 V or 3.3 V bank power where SD signals are connected

Impact: Select SD level shifter voltage according to module specification

#5 Added power switch for SD level shifter supply voltages

Type: Schematic change

Reason: Ensure power sequenzing of level shifter

Impact: Power sequenzing respected under any circumstances

#6 Replaced R5 by 1 kOhm and VBUS capacitors by 4.7 µF, add 0 Ohm resistors to OTG-ID net

Type: BOM change

Reason: Ensure USB-OTG compability

Impact: Board compatible to new version with microUSB connector and OTG capability

#7 Replaced jumpers by SMD versions, moved VBAT to other position

Type: Layout change

Reason: Optimize production cost

Impact: None

#8 Routing lenght of  differential pairs B34_L17,  B34_L15, B34_L21, B34_L13, B34_L10, B34_L20 changed

Type: Layout change

Reason: Other changes and limited space on PCB

Impact: Applications with exact timing requirements on these IOs have to be checked and if necessary adjusted

Method of Identification

The model code and revision number (e.g. TE0703-05 or TE0703-06) are printed on the top side of the PCB above the SD card slot.
