Mixed-Signal SoC sets new standards for
ultra-low-power, always-listening voice trigger
ON Semiconductor (Nasdaq: ON), driving energy efficiency
innovations, has introduced BelaSigna® R281, a new “always
listening” voice trigger System-on-Chip (SoC) solution designed for
popular consumer electronics devices such as smartphones, tablets
and wearable devices. Using an audio pattern-matching algorithm
developed by ON Semiconductor, BelaSigna R281 can detect a single,
user-trained trigger phrase. This phrase can be any series of
sounds, and is neither speech nor language dependent. Upon
recognizing this trigger phrase, BelaSigna R281 will assert a
wake-up signal which, when connected to a host controller,
alleviates the need for users to touch their device to wake it
prior to use.
Based on ultra-low-power technology developed for the advanced
hearing aid solutions that the company is already well-known for,
BelaSigna R281 has virtually no impact on standby battery life.
Unlike some standalone solutions which are only compatible with
digital microphones, BelaSigna R281’s mixed-signal architecture
works with both analog and digital microphone signals. The device
provides a configurable, regulated microphone supply to facilitate
simple integration. Other key features of BelaSigna R281 include an
I2C interface for configuration and control, a configurable GPIO
wake-up signal, and an internal oscillator.
BelaSigna R281 is available in a 5 mm x 5 mm QFN32 package and
will soon also be available in an ultra-miniature 2.42 mm x 2.74 mm
WLCSP. Both packages can be designed onto a single-sided PCB with 4
mil routing and a minimal amount of external components, providing
one of the simplest solutions available for always-on,
always-listening voice trigger.
“As the popularity of portable and wearable electronics devices
has continued to grow, so has the demand for true hands-free
operation,” said Michel De Mey, Senior Director, ON Semiconductor.
“BelaSigna R281 supports voice triggered wake-up without placing
unacceptable demands in terms of power, space, design-in
complexity, and cost.”
