EVISION
Final Datasheet. Updated DC and AC Electical Characteristics Tables.
Added missing 16 Mode (Intel) data bus read timing diagram.
Updated DC Electrical Characteristics to include ICC and Sleep/Power-Save current for
final production devices of 48-TQFP and 32-QFN packages.
Corrected 32-QFN package dimension descriptions. Added GND center pad pin descrip-
tion.
Corrected 32-QFN pinout on page 2 (pinout with 16/68# pin connected to GND is for
Motorola bus mode).
Added 28-QFN and 24-QFN packages. The modem pins DTR#, DSR#, RI# and CD# are
not available in the 28-QFN package. The modem pins RTS#, CTS#, DTR#, DSR#, RI#
and CD# are not available in the 24-QFN package.
