STMicroelectronics' Connectivity Solutions for Sleeker Smart Buildings to Showcase at Light & Building 2018
March 16 2018 - 4:01AM
- Highly integrated chip for wired KNX-certified connectivity,
co-created with Tapko Technologies, is industry's smallest at 4mm x
4mm
- KNX software stack, together with a companion STM32
microcontroller, accelerates time to market for complete
network-node solution
- Early adopter Vimar demonstrates new products based on ST's KNX
transceiver at Light & Building 2018
Geneva, March 16, 2018 - STMicroelectronics (NYSE: STM),
a global semiconductor leader serving customers across the spectrum
of electronics applications, is teaming with Tapko Technologies
GmbH at Light & Building 2018 to demonstrate a highly
integrated and space-saving connectivity solution certified for the
popular KNX standard for building-automation applications.
On display at the Tapko Technologies booth, E30, Hall 9.1, the
STKNX functions as a complete KNX transceiver for twisted-pair
wired connectivity in Tapko devices, with power circuitry on-chip
in a uniquely compact footprint of just 4mm x 4mm. It can be used
for connecting devices like smart lights, switches, HVAC
controllers, alarms, or smart appliances to KNX twisted-pair
networks.
As well as its unique space-saving advantage, the STKNX helps
customers get new building-automation products to market faster as
part of a complete network-node solution that includes the KNX
software stack, co-created by ST and Tapko. The stack is ready to
run on any host microcontroller from ST's STM32[1] family.
The quick-start evaluation kit, EVALKITSTKNX, is also available,
containing everything needed to build a KNX node including a
STM32F103RBT6 microcontroller, Arduino-compatible headers for
custom function expansion, and a sample LED-dimming
application.
At Light & Building 2018, automation innovator Vimar S.p.A
(booth C72, Hall 11.1), one of the first companies to adopt the
STKNX in new designs, will demonstrate the first product of a
technically advanced new range containing the transceiver.
"We are utilizing the STKNX transceiver as an important part of
our new generation of products for home and building automation
systems," said Alessandro Ravagnin, Systems Marketing Manager Vimar
SpA. "Light & Building 2018 sees the world premiere of our new,
future-focused product line, which delivers unprecedented
performance over wired fieldbus connectivity. As is the Vimar way,
we have combined comfort, security, and energy efficiency -- the
main pillars of smart home and smart building -- with a unique user
experience, great aesthetic appeal, and a perfectly coordinated
ecosystem."
Domenico Arrigo, General Manager Industrial and Power Conversion
Division, STMicroelectronics, commented, "Our successful
cooperation with Tapko has delivered software and hardware for
product developers to create highly functional and stylish
building-automation products that enhance both the convenience and
the appearance of homes and offices."
The STKNX transceiver is available now in 0.5mm-pitch 24-pin
VQFNPN24. Please contact your ST sales office for pricing options,
sample requests, and support tools.
Notes for editors:
The KNX open fieldbus specification is widely adopted by
building-automation standards, including European EN 50090 and EN
13321-1/2 standards, the global ISO/IEC 14543-3 standard, and
Chinese GB/T 20965. KNX is also referenced in the US ANSI/ASHRAE
standard 135.
Measuring just 4mm x 4mm x 1mm in the VQFNPN24 package, the
STKNX is the smallest transceiver certified for KNX TP1-256
twisted-pair connections currently on the market. At the same time,
it features a higher level of integration than some other
transceivers, and is designed for crystal-less operation, thereby
saving even more space by eliminating external components while
also helping simplify design.
The integrated KNX bus power extractor provides up to 30mA to
the integrated voltage regulators to power external devices and the
STKNX transceiver's own power needs, while limiting the bus current
slew rate according to KNX specifications, further enhancing the
system efficiency. The on-chip voltage regulators include a
selectable 3.3V/5V 20mA linear regulator and 150mA high-efficiency
DC/DC step-down switching converter with adjustable output voltage
from 1V to 12V, which can be used to power external components. In
addition, the STKNX integrates circuitry to ensure safe coupling to
the bus and implements bus monitoring to protect against loss of
bus power.
