Lighting Reference Design kit adds wireless control and streamlines
development
Freescale Semiconductor is updating its
Lighting Reference Design discussed in
FTM1001, delivering increased functionality
and ease of use by adding ZigBeeR-based
wireless control of three (RGB) or four (RGBW
or RGBA) LEDs to the existing DALI and
DMX512-A/RDM LED protocols, and also by
using the modular Tower System development
platform.
Also updated is the colour-balance software
that currently controls the colour balance
between the three or four LED colour clusters
within the lighting system. The software will
be updated to allow colour-temperature
selection, such as from warm white to cool
white.
The Windows-based PC GUI that allowed the
user to select a colour and luminosity per LED,
via either the sRGB or CIE 1931 colour spaces,
Freescale
Semiconductor
will be integrated into the Freescale Tower
development tool using eGUI, Freescale’s
royalty-free embedded graphics software. This
will remove the need for a separate PC and will
create a self-contained lighting-control system
for LED-based lights.
The embedded hardware will include an
LED-controller board built to run within
the Freescale Tower System. The controller
board features a Freescale Kinetis ARM®
Cortex™-M4 MCU (MK60N512VMD), and will
connect to a separate DALI/DMX512-A/ZigBee
communications board via the Tower System
elevator boards. This arrangement will be able
to control multiple driver boards for single or
multiple LED clusters.
The Kinetis MCU will also drive a touchscreen-
LCD daughter card attached to the side of
the Tower system. The Kinetis MCU will run
the Freescale MQX™ RTOS (available free-of-
charge) using one execution thread to run the
eGUI driving the LCD panel and other threads
to handle wired or wireless communications
with the LED-based lights in the system.

with the longest battery lifetime through our
intelligent power management for mobile
applications. It allows our customers to create
unique looking devices while minimizing
design effort through the AS1119’s flexibility.
The AS1119 also saves space & cost by
reducing external component count,
reducing connector pin count and the
number of PCB layers.
Only 18 lines are required to drive all
144 LEDs. This is accomplished with
austriamicrosystems’ multiplexing technique
called cross-plexing. This allows reducing the
line count on the PCB as well as fewer pins on
the connectors, saving space & costs.
The AS1119 is available in a 36-pin WL-
CSP 3x3 mm package and operates over a
temperature range of -40 to +85 °C over a
wide 2.7 to 5.5 V power supply range.
AS1119 drives 144 LEDs, creating colorful and smooth animations
while extending battery life, features best dimming control and on-
chip charge pump
The AS1119 is the most advanced and
smallest LED dot-matrix driver (channels vs.
PCB space) available. The AS1119 drives 144
LEDs but requires only 9 mm² PCB space,
reduces external component count, reduces
connector pin count and requires fewer PCB
layers. Benefits for end users include up to
80% longer battery lifetime, more colorful
effects and smoother running animations.
The AS1119 is targeted for dot matrix displays
in mobile phones, personal electronics and
toys.
The AS1119 leads the industry by driving
the most LEDs, each with an 8-bit dimming
control and no external resistor required.
Additionally, an 8-bit analog current
control allows fine tuning of each matrix
to compensate for different brightness of
different colors, or to adjust the white balance
on RGB LEDs. The AS1119 incorporates 6
frames of memory for small animations or
for use as a buffer to reduce host processor
load, thereby saving energy and precious
processing time. The AS1119 also extends
battery life by including an on-chip 320 mA
charge pump which is required when LEDs
require a higher voltage than the battery can
supply, allowing continuous operation even
under low battery voltage conditions.
Other features include control via a 1 MHz I²C
compatible interface, open and shorted LED
error detection, and low-power shutdown
current. Two modes of operation are offered
making the AS1119 a very flexible part to
design with -- single/bicolor mode to drive
the maximum number of LEDs in two 8x9
matrix, or the RGB mode offering three
times 5x6 matrix, allowing white balance by
adjusting the analog current in each matrix.
The AS1119 is the most advanced and
smallest dot matrix LED driver available on
the market. It enables creative light design
