9.1.5.3
The SC1200/SC1201 processor’s current is highly depen-
dent on two functional characteristics, DCLK (DOT clock)
and SDRAM frequency. Table 9-5 shows how these factors
are controlled when measuring the typical average and
absolute maximum processor current parameters.
Note 1. See Table 9-3 on page 366 for nominal and maximum voltages.
Note 2. A DCLK frequency of 50 MHz is derived by setting the display mode to 800x600x8 bpp at 75 Hz, using a display
Note 3. A DCLK frequency of 135 MHz is derived by setting the display mode to 1280x1024x8 bpp at 75 Hz, using a display

Table 9-6 and Table 9-7 show the DC current measure-
ments
SC1200/SC1201 processor supports TV, CRT, and TFT
displays, but it is expected that generally only one display
interface
SC1200/SC1201 processor is different with different dis-
plays. The CRT and TV DACs require current, while the
TFT interface even though it has no DAC to power, also
draws current while it is active. The CRT and TV DACs and
the TFT interface are presented as separate line items.
The chosen display type I/O current should be added to the
Typical, Absolute Maximum, and Active Idle I/O currents to
get total current.
