(1) This variant has already ISSI DDR3 assembled, therefore the article number is not changed. See also section Method of Identification.
Changes
#1 Change DDR3 RAM (U3, U5) 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
...
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.
...
Clock Revision Change (U33) SiT8008AI-73-XXS-52.000000E to SiT8008BI-73-XXS-52.000000E
Type: BOM change
Reason: Switch to actual revision. Revision A devices may be discontinued.
Impact: None.
#3 Change Ferrite Beads (L1 .. L7, L11 .. L13) BKP0603HS121-T to MPZ0603S121HT000
Type: BOM change
Reason: Part is NRND and EOL announced.
Impact: None. DC resistance decreased from 150mOhm to 130mOhm, rated current increased from 0.85A to 1A.
#4 Set S/N to not fitted
Type: BOM change
Reason: Part is end of life.
Impact: Track it pad no more available. Pin 20 of CPLD was connected via S/N to GND and is now floating. However pin is not used in delivery CPLD Firmware, so no further impact.
