ROHM Shows Its New Portfolio of Low Power Products for
Wearable Devices
New products leverage the ROHM group ‘s expertise
in advanced sensor and embedded technologies
Willich-Münchheide/Munich, November 11th 2014 – At electronica in Munich
the ROHM group (ROHM, LAPIS, Kionix) displays its new broad range of ultra-low
power devices like MCUs, wireless products such as Bluetooth Low Energy (LE)
receivers, market leading accelerometers as well as other advanced sensors.
These products are perfectly suited to develop embedded technology solutions
and versatile wearable devices that provide unprecedented functionality.
(electronica Hall A-5, Booth 562).
Evolvements such as the “internet of things” and a growing number of wearable
applications drive the development of new technologies for smart embedded
devices. The components have to be light-weight, compact and highly-efficient,
able to track, monitor respectively measure activity, gesture, UV radiation,
distance, offer audio functionality or detect metal. Adding the deliberate feature
of each single device, empowers multi-functional applications - i.e. keys, tabloids
or smartphones – which provides comfortable services, safety and added lifestyle
quality to end-customers.
ROHM will display a demo (wireless key device) which combines a Sensor Hub
MCU, Bluetooth LE Transceiver and seven sophisticated sensors. The key device
communicates to the tablet or smartphone via Bluetooth Low Energy (LE). The
individual elements are mounted on an ultra-small board (18mm depth, 42mm
width and 92mm length) and run complex functionality in power-optimized mode.
Low Power MCUs
The sensor hub MCU for the sensor control is equipped with LAPIS’ original highperformance 8bit RISC Core which enables considerable power reduction on one
and high-performance on the other side. It features ultra-low power consumption
in Halt mode and on-board programming due to its Flash ROM. Thus, the device is
ideally suited for smartphones and sensor network modules.
Bluetooth Low Energy
The Bluetooth LE IC ML7105 which is compliant to Bluetooth® SIG Core Spec
v4.0. offers an integrated baseband controller compatible with Bluetooth® LE
single mode. The built-in low power consumption RF block as well ensures energy
efficiency and the interfaces support SPI (Slave)/UART/I2C (Master/Slave). With
an active power consumption of less than 9mA (TX & RX)the ML7105 is one of the
most efficient Bluetooth LE controller on the market.
Accelerometer Sensors
The low-noise, low-power accelerometers in a 10pin and 12pin LGA packages
feature a resolution up to 14-bit and optimized power management - only 0.9uA
at standby, 10uA at low resolution, 145uA at high resolution. They integrate a
wake-up function and programmable dual-state and are used for activity
monitoring, gesture control or distance measurement.
Magnetometers
The magnetometer is based on unique production methods, nano-technology and
elaborate materials like amorphous metal, leading to ultra-high sensitivity: MI
sensors can detect minute magnetic fields at the pT (pico Tesla) level – this way,
they are 10.000 times more sensitive than conventional magnetic sensors and are
a.o. used for metal object detection.
Barometric pressure sensors
The simple MEMS design of the barometric pressure sensor enables a smaller
sizing. The sensor includes piezo-resistive MEMS used to detect the difference
between atmospheric and vacuum pressure. Therefore, the sensor fits altitude
detection e.g. in navigation systems as well as weather forecasting, and is used
together with the accelerometer to monitor activity.
Proximity Sensors
ROHM’s proximity sensors fancy an ambient light sensor (ALS) IC and integrate a
LED driver to drive an external infrared LED. Nearby objects are detected by
sensing reflected light. The built-in ALS sensor optimizes LCD brightness based on
ambient conditions, increasing visibility and output sensitivity while minimizing
power consumption.
UV Sensors
The company’s ultraviolet sensors in a compact, low-profile QFN package sense
UV rays optically. They enable uniform output voltage by trimming while their
analog voltage output is proportional to UV light intensity. They guarantee low
current operation (typically 300uA) and during stand-by typically 0.1uA. ROHM
currently works on even smaller CSP packaging versions.
Availability
MCU, Bluetooth LE, Accelerometer, ALS and UV Sensor are already available
Magnetometers and Barometric Sensors are in Sample stage
