ST: STM32 software package brings
Amazon Alexa technology to simple
connected objects
The X-CUBE-AVS software package from
STMicroelectronics enables Amazon’s Alexa
Voice Service (AVS) to run on STM32 micro-
controllers, allowing simple connected
objects such as smart appliances, home-au-
tomation devices, and office products to sup-
port advanced conversational user interfaces
with Cloud-based intelligence like automatic
speech recognition and natural-language
understanding.
Renesas completes RZ/N1 solution kit
lineup
Renesas Electronics announced its latest solu-
tion kit based on the RZ/N1L Group of micro-
processors. In addition to the RZ/N1D Group
for high-end processors for master devices
including Programmable Logic Controller
and the RZ/N1S Group for mid-range devices
including Human Machine Interface, the
RZ/N Series includes the RZ/N1L Group is
optimized for slave devices including remote
IO and communication modules, and net-
worked drives. Solution kits for RZ/N1D and
RZ/N1S are already available.
ON Semi: new set of low power, fully
compliant USB-C 1.3 devices
ON Semiconductor has announced the latest
set of USB-C (Type-C) devices that are fully
compliant with the latest revision 1.3 specifi-
cation, enabling easy integration into USB-C
systems. The new devices include two con-
trollers and a switch, all of which are aimed at
applications such as smartphones, tablets, and
laptops, as well as industrial and automotive
use cases.
MACOM expands 5G optical connectivity
portfolio with 28Gbps TIAs
MACOM announced the sampling and
pre-production of the new 28Gbps tran-
simpedance amplifiers (TIA), including the
MATA-03003 and MATA-03006 devices. This
high-performance TIA solution supports data
rates from 8.5 Gbps to 28 Gbps for 25G CPRI,
25G Ethernet and 32G Fibre Channel applica-
tions while featuring low power, high sensitiv-
ity/overload, reduced die size and flexibility in
optical sub-assembly (OSA) for SFP28 optical
modules.
Cypress: support for Platform Security
Architecture Trusted Firmware-M from
Arm
Cypress Semiconductor announced avail-
ability of the Platform Security Architecture
Trusted Firmware-M reference example from
Arm for its PSoC 6 microcontrollers, enabling
a solution that adheres to the highest level of
protection as defined by PSA. By leveraging
PSA’s holistic set of threat models, security
analyses, hardware and firmware architecture
specifications, and Trusted Firmware-M ref-
erence implementation, Internet of Things
designers can quickly and easily implement
secure designs with PSoC 6 MCUs.
Renesas: chip-to-cloud IoT connectivity
with new Enterprise Cloud Toolbox
Renesas Electronics announced the new Rene-
sas Synergy Enterprise Cloud Toolbox v1.1 --
a software Application Project that together
with the Synergy AE-CLOUD1 kit provides a
reference design and starting point for users
to connect in 10 minutes or less to enterprise
clouds such as Microsoft Azure, Amazon Web
Services, and Google Cloud Platform.
Silicon Labs: Wi-Fi devices for the IoT
slash power consumption in half
Silicon Labs has introduced a new Wi-Fi port-
folio to simplify the design of power-sensitive,
battery-operated Wi-Fi products including
IP security cameras, point-of-sale terminals
and consumer health care devices. Optimized
for exceptional energy efficiency, the WF200
transceivers and WFM200 modules support
2.4 GHz 802.11 b/g/n Wi-Fi while delivering
the high performance and reliable connec-
tivity necessary as the number of connected
devices increases in home and commercial
networks.
Toshiba: photocoupler with UVLO for
digitally controlled switching power
supplies and IPM drives
Toshiba Electronics Europe launched a new
high-speed IC-Photocoupler for MOSFET gate
signal insulation. The TLP2735 is Toshiba’s first
photocoupler to incorporate an under-volt-
age lockout (UVLO) function with hysteresis.
UVLO reduces the photocouplers susceptibil-
ity to noise that is often generated in power
supply cables, and can prevent malfunctions
at switch on. With an isolation voltage of min.
iC-Haus: high-resolution absolute
encoder iCs for nonius interpolation
A minimal sensor area of only 1.9 x 3.3 mm
is sufficient for the optical sensors in the
iC-PNH series to scan encoder code discs and
generate sine signals in top hi-fi quality. Eval-
uation is executed by interpolation ICs using a
Nonius calculation, e.g. iC-MN and iC-MNF,
permitting a very high angle resolution of
more than 21 bits, even with code disc diame-
ters of only 26 mm.
ROHM receives certification under
ISO26262
ROHM has received certification for the
development process under the ISO 26262
functional safety standard for automo-
tive products by third-party certification
authority TÜV Rheinland in Germany. This
certification allows ROHM to develop auto-
motive-grade devices that achieve the highest
level of safety (ASIL-D). ISO 26262 was for-
mulated in 2011 as an international standard
for functional safety in response to the rising
demand for safety performance along with
the increasing automation and functionality
required in the worldwide automotive market.
Allegro MicroSystems: automotive
sinusoidal sensorless BLDC fan driver IC
Allegro MicroSystems Europe has announced
a new sensorless BLDC controller. The
A5932 three-phase BLDC motor controller
solution is targeted at high-power automo-
tive fan applications with very low vibration
and audible noise requirements. MOSFET
gate driver outputs permit motor currents
that can be scaled to fit the applications
requirements.
Maxim: small step-down converters
Rohde & Schwarz: WLAN signaling tester
to emulate all IEEE 802.11a/b/g/n/ac
standards
Before now, the RF properties of WLAN sta-
tions (STA) were mainly tested in an artificial
remote control operation, the non-signaling
mode. For IEEE 802.11ax, this is only pos-
sible to a certain extent. IEEE 802.11ax uses
OFDMA technology to significantly increase
the efficiency of WLAN networks. The avail-
able bandwidth is shared between multiple
STAs that simultaneously transmit to the
access point.
