Freescale Semiconductor
LCDIF
LCD Interface Multimedia
peripherals
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.
LRADC
Low resolution
ADC module
Connectivity
peripherals
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.
OCOTP
Controller
On-chip OTP
controller
Security
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.
PINCTRL
Pin control
and GPIO
System control
peripherals
Used for general purpose input/output to external ICs. Each GPIO bank
supports 32 bits of I/O.
PMU
Power
management
Unit (DC-DC)
Power
management
system
The i.MX28 integrates a comprehensive power supply subsystem, including
the following features:
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,
VDDIO, VDD4P2 and 5-V supplies.
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
connected to a 5-V source and allows the DCDC to run from a 5-V source
with a depleted battery.
The 4.2-V regulated output also allows for programmable current limits:
– Battery Charge current + DCDC input current < the 5-V current limit
– DCDC input current (which ultimately provides current to the on-chip
and off-chip loads) as the priority and battery charge current is
automatically reduced if the 5-V current limit is reached
PWM(8)
Pulse width
modulation
Connectivity
peripherals
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.
PXP
Pixel Pipeline Multimedia
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.
