Subsystem
The LCDIF provides display data for external LCD panels from simple
text-only displays to WVGA, 16/18/24 bpp color TFT panels. The LCDIF
supports all of these different interfaces by providing fully programmable
functionality and sharing register space, FIFOs, and ALU resources at the
same time. The LCDIF supports RGB (DOTCLK) modes as well as system
mode including both VSYNC and WSYNC modes.
The sixteen-channel 12-bit low-resolution ADC (LRADC) block is used for
voltage measurement. Channels 0 – 6 measure the voltage on the seven
application-dependent LRADC pins. The auxiliary channels can be used for
a variety of uses, including a resistor-divider-based wired remote control,
external temperature sensing, touch-screen, and other measurement
functions.
The on-chip one-time-programmable (OCOTP) ROM serves the functions of
hardware and software capability bits, Freescale operations and unique-ID,
the customer-programmable cryptography key, and storage of various ROM
configuration bits.
Used for general purpose input/output to external ICs. Each GPIO bank
supports 32 bits of I/O.
The i.MX28 integrates a comprehensive power supply subsystem, including
the following features:
There are eight PWM output controllers that can be used in place of GPIO
pins. Applications include HSADC driving signals and LED & backlight
brightness control. Independent output control of each phase allows 0, 1, or
high-impedance to be independently selected for the active and inactive
phases. Individual outputs can be run in lock step with guaranteed
non-overlapping portions for differential drive applications.
The pixel pipeline (PXP) is used to perform alpha blending of graphic or video
buffers with graphics data before sending to an LCD display. The PXP also
supports image rotation for hand-held devices that require both portrait and
landscape image support.
• One integrated DC-DC converter that supports Li-Ion battery.
• Four linear regulators directly power the supply rails from 5-V.
• Linear battery charger for Li-Ion cells.
• Battery voltage and brownout detection monitoring for VDDD, VDDA,
• Integrated current limiter from 5-V power source.
• Reset controller.
• System monitors for temperature and speed.
• Generates USB-Host 5-V from Li-Ion battery (using PWM).
• Support for on-the-fly transitioning between 5-V and battery power.
• VDD4P2, a nominal 4.2-V supply, is available when the i.MX28 is
• The 4.2-V regulated output also allows for programmable current limits:

connected to a 5-V source and allows the DCDC to run from a 5-V source
with a depleted battery.
– Battery Charge current + DCDC input current < the 5-V current limit
