Changes
#1 Changed DDR4 SDRAM (U2, U3, U9, U12) from NT5AD256M16D4-HR (512 MByte) to IS43QR16512A-075VBLI (1 GByte).
Type: Schematic Change
Reason: EOL of Component.
Impact: With increased memory size also static and dynamic (usage dependent) power consumption is increased. If relevant for your application, please compare IDD current values of corresponding memory datasheets. Memory design settings needs to be reviewed/updated in customer design. Reference designs for variants with new memory are available. Refer to ZynqMP DDR4 Memory Setup for additional information.
#2 Changed DDR4 SDRAM (U2, U3, U9, U12) from K4A8G165WC-BITDTCT to IS43QR16512A-075VBLI.
Type: BOM change
Reason: EOL of Component.
Impact: New DDR timings may be considered in designs. DDR4 setup used in reference design is known to work still according to ZynqMP DDR4 Memory Setup.
#3 Changed DCDC (U13, U15, U16, U19, U20, U23, U24, U29, U30, U31) from MUN3CAD03-SE to TPS82085SIL and adapted voltage divider resistors.
Type: BOM Change
Reason: TPS82085SIL availability.
Impact: Minor changes in electrical characteristics.
Method of Identification
Locate DDR4 SDRAM (U2, U3, U9, U12) on top side of TE0803-04 PCB:
