devices. The sensor solutions
offer best-in-class performance for
headphones, fitness bands, smart
watches and phones. They are
integrating three LED outputs, a
photodetector, a low-noise analog
front-end, a digital interface and a
state machine into a single die. For
best application results the bare die
is either packaged with an infrared
or a green LED or can drive up to
three external LEDs.
The sensors offer a fully integrated
solution for optical heart rate
measurement featuring an I²C
interface for a programmable
sample rate of up to 256 per second.
This allows a significantly better
signal-to-noise ratio (SNR) than
discrete alternatives. Additionally,
monitoring algorithms can filter out
motion artifacts and deliver precise
heart rate and pulse oximetry
measurements during exercise.
High optical sensor resolution
enables accurate measurement
across the widest possible variety
of skin types, while high optical
sensitivity reduces photo diode
area and drives down LED power
consumption with a typical 300 μA
LED current on fair skin. A standby
current of just 0.3 μA further reduces
power consumption.
Availability
Infineon and GoerTek sensor
solutions are available either as bare
die or as packaged products with
application algorithm fromInfineon’s
long-term
partnerGoerTek.
Packages measure just 3.94 mm
x 2.36 mm x 1.35 mm. Packaged
samples are available now, with
volume production targeted in
August 2016. In addition to the
bare die chips from Infineon,
GoerTek is offering starter kits and
demonstration boards for designers
looking to rapidly evaluate and test
the technology for use in their smart
applications.
ON Semiconductor
Expands Low Power Wireless
Solutions Portfolio with
SIGFOX and ARM for Rapid
IoT Deployment
ON Semiconductor (Nasdaq: ON),
driving energy efficient innovations,
has announced two major strategic
developments to enable rapid
deployment of Internet of Things
(IoT) solutions.
Working in conjunction with
SIGFOX, the world’s leading
provider of dedicated connectivity
for the Internet of Things (IoT), ON
Semiconductorhasconfirmed that its
AX-SFEU system-on-chip (SoC) is
now fully SIGFOX Ready™ certified
for optimal two-way communication
in Europe with certification
underway for the US. Through the
AX-SF SoC, plus its accompanying
library and development system,
IoT developers will be able to easily
use SIGFOX’s long range, two-
way global IoT network – resulting
in a low cost, low-power device-to-
cloud connectivity solution that is
highly optimized for environmental
sensors, smart meters, patient
monitors,
security
devices,
streetlights and a broad spectrum
of other industrial and consumer-
oriented applications.
The AX-SF SoC draws under 10
milliamperes (mA) of current when
receiving data and has a sensitivity
of -129 decibel-milliwatt (dBm) at
600 bits/second (bps) with GFSK
modulation. The reference design,
which does not require an expensive
front-end module, features a 23
dBm transmitter and has only a
220 mA current consumption,
enabling designers to markedly
extend communication range while
maximizing battery life.
ON Semiconductor also announced
that it is now an official ARM®
mbed™ partner. The NCS36510
2.4 gigahertz (GHz) IEEE 802.15.4
compliant transceiver platform will
include the mbed OS and Thread
stack. Access to the ARM mbed
ecosystem in combination with
Thread will again prove highly
beneficial for IoT developers,
helping them to produce more agile,
robust, cost-effective solutions
with end-to-end security and lower
power budgets that better address
their application demands.
“ON Semiconductor was very
early to recognize and respond
to demands for transceivers that
provide
extremely
low-power,
wireless connectivity for the IoT,”
states Stuart Lodge, Executive
Vice President of Global Sales
and Partners at SIGFOX. “Our
fast-growing operated network,
currently in 18 countries including
the US and registering over 7 million
devices, requires a reliable supply
of high performance, low-cost and
extremelyenergy-efficientintegrated
circuits, and our collaboration with
ON Semiconductor helps assure
