Type: Schematic Change
Reason: Remove floating signal situation.
Impact: Module powers-up automatically when VIN and 3.3VIN is available. Baseboard needs to handle signal "EN1" to determine power-up and power-down.
Type: Schematic Change
Reason: Remove floating signal situations and enable signal detection by CPLD.
Impact: None. Firmware reflects it but custom firmware needs to be updated by customer.
Type: Schematic Change
Reason: Remove floating signal situation.
Impact: Clock (U3) powers-up automatically when 3.3V is available. FPGA (U1) can only disable clock. FPGA-firmware-design needs to be checked by customer.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None. Increased current output capability. Minor changes in electrical characteristics.
Type: Schematic Change
Reason: Improve power rail quality.
Impact: None. Improvements in electrical characteristics.
Type: Schematic Change
Reason: Keep FPGA in reset while signal "PROG_B" is low during initial power-up.
Impact: None.
Type: Schematic Change
Reason: Improved power monitoring.
Impact: Improved power monitoring circuit by supervising additional voltage rails. If monitored voltages are out of range signal "PG_ALL" is triggered.
Type: Schematic Change
Reason: Improved ESD protection.
Impact: None. Improved ESD protection.
Type: Schematic Change
Reason: Revision ID indication.
Impact: None. Firmware reflects it but custom firmware needs to be updated by customer.
Type: PCB Change
Reason: Required for export to UK.
Impact: None.
Type: PCB change
Reason: Result of changes above.
Impact: Changed trace length have to be taken into account in existing designs. The trace length for new revision will be available in 4x5 series pinout generator. Please check if change in trace length still matches your requirements. Adaption of carrier may be necessary.
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.
Type: Documentation Update
Reason: Documentation improvement.
Impact: None.
The revision number is shown on the top side of the PCB.
From January 2024, after old stock is gone. If the new revision is not suitable for your application and still the former revision of the board is needed, please contact us.
