10 Jun 2009 In Section 2.2, “Supply voltage sequencing” added the following note:
NOTE
All I/O VDD pins must be powered on when the device is functioning,
except when in standby mode.
In standby mode, all I/O VDD pins, except VSTBY_RTC (battery), can
be switched off.
Added Section 3.2, “Pinout—169 MAPBGA” and Section 3.3, “Pinout—256 MAPBGA” and updated Table 5 with
Added USB OTG, USB host, ADC, DAC/ADC, and RTC standby supply voltages
Added RTC standby supply voltage
Split out Power Supplies and I/O Characteristics to two separate tables
Changed maximum frequency to 100MHz and updated specs throughout the table
Changed FB2 maximum from 5 to 6
Changed minimum frequency from 50 to 100
Changed maximum DD1 from 20 to 10
