Notes
Non-classified release.
Updated Section 4, “Voltage, Temperature, and Timing Specifications,” for the
C-0 stepping.
• Corrected EEMODE signal description.
• Updated signal names to match design guide and reference schematics.
• Added lead free information.
• Added information about migrating from a 2-layer 0.36 mm wide-trace
substrate to a 2-layer 0.32 mm wide-trace substrate. Refer to the section
on Package and Pinout Information.
• Added statement that no changes to existing soldering processes are
needed for the 2-layer 0.32 mm wide-trace substrate change in the
section describing “Package Information”.
• Corrected pinout discrepancies between sections “Signal Descriptions”
and “Package and Pinout Information”.
• Added new maximum values for DC supply voltages on 1.2 V and 1.8 V
pins. See Table 2, Recommended Operating Conditions and Table 6, DC
Characteristics.
• Updated Visual Pin Assignment diagram for pinouts F9, F10, E14, F14,
and H14.
• Removed all references to CLK_RUN# signal.
• Corrected the FLSH_SO/LAN_DISABLE signal definition. If Flash
functionality is not used then an external pull-down resistor is required.
• Added pin C8 description to Table 29 and Table 31.
• Corrected 25 MHz Clock Input Requirements in Table 13.
• Corrected the FLSH_SO/LAN_DISABLE signal definition. If Flash
functionality is not used then an external pull-up resistor is required.
• Updated Table 13 “25 MHz Clock Input Requirements”.
• Updated Table 40 descriptions for pins A10, B10, and C9.
• Updated pinout descriptions from Tables 25 - 42 to match Figure 13.
• Removed note “b” from Table 2 and note “a” from Tables 3 and 4. Moved
the note following Table 5 before Table 3 “3.3V Supply Voltage Ramp”.
