Changes

#1 Change DDR3 RAM (U12, U13) from IM4G16D3FABG-125I to IS43TR16256BL-125KBLI

Type: BOM change
Reason: Component is end of life.
Impact: New DDR timings may be considered in designs. DDR3 setup used in reference design is known to work still.

#2 Replaced Flash (U7) to IS25LP512M-RHLE All SoMs use S25FL256SAGBHI20 Flash (U7)

Type: BOM change
Reason: Ensure long time availability.
Impact: Jedec Manufacturer ID changed from 01h to 9Dh, the device ID from 18h to 19h. 512Mbit flash are now available. 

Type: BOM change
Reason: The planned IS25LP512M-RHLE is listed as 'Supported Flash Memory Devices for Zynq-7000 Device Configuration' in Xilinx UG908 (since version 2019.1), but there are unsolved problems with reboot after petalinux was started. Therefore this change is canceled. Only modules where other than S25FL256SAGBHI20 was used are changed to S25FL256SAGBHI20.
Impact: Jedec Manufacturer ID is 01h, the device ID 0219h. Size does not change, 256 Mbit flash are available. 

#3 Change eMMC (U15) to IS21ES08G-JCLI

Type: BOM change
Reason: Improve availability.
Impact: Most of the variants had installed 4GB. For this variants the eMMC capacity is increased to 8 GByte.

#4 Clock Revision Change (U6, U14) SiT8008AI-... to SiT8008BI-...

Type: BOM change
Reason: Switch to actual revision. Revision A devices may be discontinued.
Impact: None. 

Please Note:

Additionaly to the changes above a CPLD update for TE0720-03 is prepared. The PCN with title 'PCN-20210127 TE0720 CPLD Firmware Revision Upgrade from REV05 to REV06' will be published mid of February 2021. New variants in the column replacement (see table above) with the only exception 61Q33FAD will have the updated CPLD Firmware. Both, new and old CPLD Firmware are compatible to all mentioned revision 03 SoM variants. The CPLD Firmware will be online available. Further detailed description will be given in the upcoming PCN.
