Changes
#1 Changed flash (U12) from S25FL127SABMFV10 to S25FL128LAGMFI013.
Type: BOM change
Reason: EOL of Component.
Impact: None, no changes in our design are necessary. JEDEC manufacturer is still the same. Modified device IDs and temperature grade from -40° C - 105 °C to -40 °C - 85 °C.
#2 Changed HyperRAM (U5) from S27KL0641DABHI02 to IS66WVH8M8DBLL-100B1LI.
Type: BOM change
Reason: EOL of Component.
Impact: None, no changes in our design are necessary. JEDEC manufacturer is still the same. Modified device IDs and temperature grade from -40° C - 105 °C to -40 °C - 85 °C.
#3 Changed DCDC EN5311QI (U2) to MPM3834CGPA-Z and adapted power circuit.
Type: Schematic Change
Reason: EOL of Component.
Impact: None. Increased output current capability. Minor changes in electrical characteristics.
#4 Changed LED (D2, D3) from 150060VS75000 to 19-213/G6C-BM1N2/DT.
Type: Schematic Change
Reason: BOM Optimization.
Impact: None.
#5 Changed LED (D4) from 150 060 RS7 500 0 to 19-213/R6C-AL1M2VY/3T.
Type: Schematic Change
Reason: BOM optimization
Impact: None.
#6 Added 19.1 kOhm pull-up resistor for signals "ICE_SPI_CS" (R16) and "ICE_CRESET" (R17).
Type: BOM change
Reason: Use external pull-up resistor.
Impact: None.
#7 Added pull-up resistor (R9) for signal "HR_CS".
Type: Schematic change
Reason: Use external pull-up resistor.
Impact: None.
#8 Changed resistor (R1, R4, R5, R21, R22) from 3.3 kOhm to 4.22 kOhm.
Type: BOM change
Reason: BOM Optimization.
Impact: None.
#9 Changed resistor (R6, R7, R20, R39) from 10 kOhm to 19.1 kOhm.
Type: BOM change
Reason: BOM Optimization.
Impact: None.
#10 Added 470 nF decoupling capacitor (C8, C9, C10) for FPGA (U1) at power rail "3V3.
Type: Schematic change
Reason: Improve power rail.
Impact: None.
#11 Changed power net name style.
Old net name (TE0887-03) | New net name (TE0887-04) |
|---|---|
| 1.2V | 1V2 |
| 3.3V | 3V3 |
| 5V | 5V0 |
Type: Schematic Change
Reason: Use updated name style convention.
Impact: None.
#12 Added test point (TP1, TP2).
Type: Schematic Change
Reason: Improve voltage measurement possibilities.
Impact: None.
