Description
Initial release.
Editorial updates and improvements throughout the document.
In Figure 4 (416 TEPBGA pinout), corrected pin P25 to VSS.
In Section 3, System design information, added Figure 6 (Power-up sequencing) and
Figure 7 (Power-down sequencing).
In Table 10 (Recommended operating conditions (3.3 V)), changed maximum Tj from
150 ^oC to 140 ^oC.
In Table 11 (Recommended operating conditions (5.0 V)), changed maximum Tj from
150 ^oC to 140 ^oC.
In Table 16 (Voltage regulator electrical characteristics):
— Changed maximum Tj from 150 ^oC to 140 ^oC.
— Changed V_DD12 post-trimming minimum value from 1.270 V to 1.26 V and
maximum value from 1.280 V to 1.29 V.
— Removed footnote: “All values in this table are PRELIMINARY.”
In Section 4.7.1, Voltage regulator electrical characteristics. added Table 17
(Low-power voltage regulator electrical characteristics) and Table 18 (Ultra
low-power voltage regulator electrical characteristics).
In Table 19 (Low voltage monitor electrical characteristics), updated the following
values:
— V_LVDHV3H maximum from 2.8 V to 2.9 V
— V_LVDHV3L minimum from 2.7 V to 2.5 V
— V_LVDHV5H maximum from 4.37 V to 4.4 V
— V_LVDHV5L minimum from 4.2 V to 3.9 V
In Table 20 (DC electrical characteristics):
— Updated I_DDRUN typical values for Dual Display Drive from 235 to 275 mA; for
Single Display Drive from 306 to 240 mA.
— Updated typical I_DDHALT current at 25 ^oC from 12.67 mA to 17.5 mA.
— Updated typical I_DDHALT current at 105 ^oC from 33.1 mA to 35 mA.
— Updated maximum I_DDHALT current at 25 ^oC from 18.26 mA to 21.5 mA.
— Updated maximum I_DDHALT current at 105 ^oC from 36.41 mA to 43.5 mA.
— In I_DDHALT specification, changed T_B = 105 ^oC to T_A = 105 ^oC.
In Table 40 (Fast internal oscillator electrical characteristics), removed RCMTRIM
specification.
In Table 41 (Slow internal RC oscillator electrical characteristics), removed
RCMTRIM specification.
In Table 44 (ADC electrical characteristics), added offset error value of 0.5 typical, and
gain error value of 0.6 typical. Removed minimum and maximum values for both
specifications.
In Section 4.18.5, DRAM interface:
— Added Table 58 (LPDDR, DDR, and DDR2 (DDR2-250) SDRAM timing
specifications).
— Removed Table 56 (AC Specs for SDR mode (V_{DDE_DR} = 3.3 V)), Table 57 (AC
Specs for DDR2 mode (V_{DDE_DR} = 1.8 V)), Table 58 (AC Specs for DDR1 mode
(V_{DDE_DR} = 2.5 V)), and Table 59 (AC Specs for LPMDDR mode (V_{DDE_DR} = 1.8
V)).
