| Title | TEI0003-02 to TEI0003-03 Hardware Revision Change |
| Subject | Hardware Revision Change |
| Issue Date | 2023-02-01 |
Products Affected
This change affects all Trenz Electronic TEI0003 boards: TEI0003-02*.
Affected Product | Replacement |
|---|---|
| TEI0003-02 | TEI0003-03-QFCR1A TEI0003-03-QFCR4A |
Changes
#1 Added option to use either SPI Flash EPCQ16SI8N / EPCQ16ASI8N (U5) or SPI Flash W25Q64JVSSIQ (U12).
Type: Schematic Change
Reason: EOL of EPCQ SPI Flash.
Impact: Different memory sizes and frequencies are available. TEI0003-03-QFCR1A used the EPCQ memory. Therefore, the size is the same. But TEI0003-03-QFCR4A used a different memory with a bigger size. The replacement TEI0003-03-QFCR1A is only usable as long as components are available. Afterwards, only TEI0003-03-QFCR4A is usable.
#2 Changed ferrid bead LI0402E300R-10 to MPZ0603S121HT000 for L1, L2, L3, and L4.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Minor changes in electrical characteristics.
#3 Changed clock DSC6011ME2A-012.0000T to DSC6011ME2B-012.0000T for U6.
Type: Schematic Change
Reason: EOL of Component
Impact: None. This clock is not assembled.
#4 Added capacitor C59 for net USB_VBUS.
Type: Schematic Change
Reason: Improve power supply.
Impact: None. Minor changes in electrical characteristics.
#5 Changed DCDC EP53A7HQI (U8) / EP53A7LQI (U10) to MPM3834CGPA-Z for U8 and U10 and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Minor changes in electrical characteristics.
#6 Added UKCA logo.
Type: PCB Change
Reason: Requiered for export to UK.
Impact: None.
#7 Added pin description on silkscreen layer.
Type: PCB Change
Reason: Improves pinout documentation.
Impact: None.
