DATA SHEET REVISION SUMMARY
REVISION
040104
DESCRIPTION
1) Removed “Preliminary” status.
2) Soldering temperature parameter now references JEDEC specification.
3) Added note to absolute maximums clarifying voltages referenced to ground and storage temperature.
4) Updated I_CC, I_IDLE, I_STOP, I_SPBG, I_IL, and I_TL to incorporate errata conditions.
5) Added note clarifying DC electrical test conditions.
6) Added note clarifying V_OH3 specification applies to first clock cycle following the transition.
7) Updated AC and MOVX electrical characteristics with final characterization values.
8) Added t_AVLL2 specification and corrected MOVX timing diagrams to show t_AVLL2 instead of t_AVLL.
9) Updated I_BAT to incorporate errata conditions.
