Low-profile, optical sensor module reduces board space requirements
and lowers smartphone BOM cost
ams AG (SIX:AMS), a leading provider of high performance sensors and
analog ICs, launched today a new series of advanced optical sensing
modules, the TMx4903, integrating multiple functions including universal
remote control, barcode emulation, RGB color sensing, proximity and 3D
gesture detection in a low-profile 5.0x2.0x1.0mm package.
The high level of integration in the TMx4903 modules reduce board space
requirements and lowers bill of material (BOM) cost while delivering
exciting new capabilities required by today’s smartphones. By
integrating multiple optical sensing functions, and an IR LED in a
module, the TMx4903 devices help to simplify smartphone board layouts
giving greater flexibility to system designers. The low-profile package
also helps designers to meet consumer demand for sleeker, slimmer and
more aesthetically pleasing smartphone designs.
The module variants in the series, the TMD4903 and TMG4903, perform
accurate color and proximity sensing, and integrate an IRBeam IR pattern
generator. The IR pattern generator emits remote control beam patterns
for any standards-compliant consumer product. The URC capability is also
compatible with the Android™ Consumer.IR programming interface for
remote-control applications on smartphones. Mobeam™ 1D barcode emulation
for use at retail point-of-sale (POS) terminals is also supported.
The TMG4903 device also provides the industry’s most advanced touchless
IR gesture-sensing capability. ams’ new 3D gesture technology enables
the recognition of complex hand gestures, supplemen-ting simple
north-south and east-west 2D gestures supported by ams’ 1st
generation TMG3992 gesture sensor.
The TMx4903 new 3D gesture and proximity capability draws on the
modules’ automatic adjustment of the IR LED’s timing and power output,
minimizing noise and power consumption while optimizing sensitivity and
dynamic range. The TMx4903 incorporates innovative circuit techniques
which rejects ambient light noise. Automatic calibration removes
electrical artifacts caused by noise and optical cross-talk. This
integrated intelligent LED drive capability eliminates the requirement
for the application processor to control LED driving functions which
simplifies the phone’s software implementation and reduces processing
capability required for instantaneous gesture recognition.
‘Today’s leading smartphones are known for integrating cutting-edge
technology, functionality and aesthetics. The space savings enabled by
the use of the TMD4903 or TMG4903 help OEMs to set new standards of
integration in the smartphone industry,’ said Darrell Benke, Senior
Product Marketing Manager for ams.
The TMD4903 and TMG4903 are available now in production volumes. Unit
pricing for the TMD4903 is $2.00 and the the TMG4903 is $2.50 in order
quantities of 1,000.
Evaluation boards for the TMD4903 and TMG4903 are available for
qualified opportunities. For additional information and to contact a
