This change affects all variations of TE0820 SoMs of revision: TE0820-02-*
affected product | suggested upgrade |
---|---|
TE0820-02-* | TE0820-03-* |
Changes
#1 Fixed VCU connection: add additional DCDC (0.9V)
Type: Fix
Reason: Follow Xilinx product integration advice.
Impact: None
#2 LIB components update
Type: PCB change
Reason: Improve production yield.
Impact: None
#3 Change package 1K resistors (0402 -> 0201)
Type: BOM Change
Reason: Improve board layout
Impact: None
#4 Added LEDs (1x user LED, 1x LED for ERR_STATUS, 1xLED for ERR_OUT)
Type: Enhancement
Reason: Function feedback desired.
Impact: LEDs available for visual feedback.
#5 Replaced obsolete 2xSPI Flash (256MBit) -> 2xSPI Flash (512MBit)
Type: BOM change
Reason: N25Q256A11E1240E became obsolete, replacement part not available for purchase. This is only interim solution because N25Q512A11G1240E is also obsolete already. It will be changed after the replacement parts get available.
Impact: Size changed from 256 MBit to 512 MBit per chip. JEDEC ID changed from BB19h to BB20h both with manufacturer ID: 20h.
#6 Added additional DCDCs (PL_VCCINT_IO, PS_FP0V85)
Type: Improvement
Reason: Allow for higher loads.
Impact: None
#7 Changed DCDC (U5) 6A (optional 4A)
Type: Improvement
Reason:Existing DCDC not stable under high load Allow for higher loads.
Impact: None
#8 Routed POR signal to A4 pin of SPI Flash chips with not fitted resistors R80, R81
Type: Schematic change
Reason: Depending on the Flash type, this pin is used as RESET.
Impact: More Flash types are compatible with the PCB.
#9 Replaced obsolet DDR4 NT5AD256M16B2-GN by K4A8G165WB-BIRC
Type: BOM change
Reason: NT5AD256M16B2-GN became obsolete.
Impact: Size changed from 4Gbit to 8Gbit.
Method of Identification
The model code and revision number (e.g. TE0820-02 or TE0820-03) are printed on the top side of the PCB.
