Summary
Initial Release
Updated AC and DC specifications. Changed AC Test Conditions and Load
Circuit.
Added unlimited endurance bullet. Changed Data Retention table.
Changed operating Vdd voltage range to 3.0 – 3.65V. Reduced Idd supply
current limits.
Updated to Production status. Added note to Output Data Valid spec.
Changed operating Vdd voltage range to 2.7 – 3.65V with separate AC timing
specs defined below 3.0V operation. Reduced input leakage spec.
Added “green” package. Updated package mechanical drawing.
Added DFN packaging option. Added DFN mechanical drawing. New rev.
number to comply with updated scheme.
Improved Data Retention spec to 45 years. Removed “preliminary” from DFN
package drawing. Added note about powering down with /CS active (pg 3).
Added ESD and package MSL ratings.
Changed DFN name to TDFN. Added TDFN pcb footprint. Corrected TDFN
package heading from 0.65mm to 0.95mm.
Removed –S package option. It is not recommended for new designs, use –G
instead. Changed/improved I
Changed TDFN Package Marking Scheme.
Removed sentence referencing Table 4 from Write Operation paragraph (p. 7).
Added tape and reel ordering information. Added note that SOIC device is
Grade 3 AEC-Q100 qualified. Added last time buy notice on –S
ordering numbers.
Not recommended for new designs. Alternative: FM25CL64B.
