The AT88CK590 evaluation kit for the CryptoAuthentication family
has a convenient USB interface for use on a PC
Atmel has made a breakthrough in the
provision of security functionality for
Internet of Things (IoT) devices and
other connected systems with the
launch of the ATECC508A, the latest
member of its CryptoAuthentication
™
product family.
The Atmel
®
ATECC508A is the first device to
implement the Elliptic Curve Diffie–Hellman
(ECDH) security protocol – an ultra-secure
method for providing key agreement when
encrypting and decrypting data shared between
two devices – in a small, low-power device
suitable for use in IoT equipment. It also
implements the Elliptic Curve Digital Signature
Algorithm (ECDSA) to provide for sign-verify
authentication.
The CryptoAuthentication portfolio now
includes two series of devices offering
advanced Elliptic Curve Cryptography (ECC)
capabilities. Because the new ATECC508A has
ECDH and ECDSA built-in, it enables design
engineers to easily provide confidentiality, data
integrity and authentication in systems that use
a microcontroller or microprocessor running
encryption/decryption algorithms such as
Advanced Encryption Standard (AES) in software.
Like all Atmel CryptoAuthentication products,
the new ATECC508A employs hardware-based
cryptographic key storage and cryptographic
counter-measures, which are more secure than
software-based key storage.
It is compatible with any MCU or MPU on the
market today. Drawing a typical current of just
3mA in Active mode, it consumes very little
power, and requires only a single general-
purpose I/O.
The ATECC508A is available in versions with
either an I
2
C or a single-wire interface, and in
eight-lead SOIC, eight-pad UDFN or three-lead
contact packages.

Combined proximity and ambient light
sensor offers display design flexibility
VISHAY
The VCNL4040 from Vishay is a fully
integrated proximity and ambient light
sensor that combines an IR emitter,
photo-detectors for proximity and
ambient light sensing, a signal-
processing IC and a 16-bit ADC in a
single chip.
When used in battery-powered products that
have a touchscreen display, the Vishay
Semiconductors VCNL4040 reduces power
consumption, because its proximity sensor
function lets the system automatically disable
the display until a user is detected.
At the same time, the ambient light sensor
supports adaptive brightness control of display
and keypad backlighting, also helping to
reduce power consumption while improving
the user experience.
Because the VCNL4040 includes all of the
circuitry needed for these applications in a
single device, it eliminates the need for
additional light barriers and for optical alignment
of the IR emitter and photodiode.
Measuring just 4mm x 2mm x 1.1mm, the
VCNL4040 gives design engineers great
flexibility in the placement of the sensor. It can
function at any depth or air gap below the
glass window, unlike sensors with resolution of
8-, 10- or 12-bits, which require a depth of
1.5mm or less. Lower-resolution devices must
also be placed away from other components
on a costly and dedicated flexible circuit, while
the 16-bit resolution of the VCNL4040 allows it
to be assembled on the main PCB.
The VCNL4040's ambient light and proximity
sensors operate in a parallel structure; each
offers a programmable Interrupt function with
high and low thresholds. The use of patented
Filtron
™
technology provides for ambient light
sensitivity that very closely matches the response
of the human eye. The device also offers an
excellent temperature-compensation capability
to keep the output stable in all conditions.
The VCNL4040 measures ambient light with
an accuracy of ±10% across a broad range
from very dark (0.01lux) conditions up to bright
sunlight (5.2klux). This means that it can be
used equally well behind a dark or a
transparent window. The sensor is immune to
fluorescent light flicker.

ESD and surge protector diode outperforms other
device types
DIODES INCORPORATED
Diodes Incorporated has announced
an automotive-grade ESD and surge
protector offering better protection
than Zener-based and varistor devices
provide, while offering the same
optical solder-inspection capabilities.
In cars, the protection of CAN and
LIN two-wire communications
buses from voltage transients is
critical to their reliability and safety.
The D24V0L1B2LPSQ, a bi-
directional ESD protection diode
rated with a typical capacitance of
6pF at a reverse voltage of 0V, is
ideally suited to this application.
Featuring 0.2Ω dynamic
resistance, the diode benefits
from sharper triggering than Zener
diodes or varistors can offer,
resulting in superior protection
from fast transients such as ESD
strikes.
D24V0L1B2LPSQ: protects LIN and CAN bus in cars
The D24V0L1B2LPSQ, housed in a tiny
DFN1006-S package, is the first of its type to
feature sidewall plating, sometimes known as
‘wettable flanks’. This means that the package
sidewall is tin-plated, allowing a solder fillet to
be formed. The solder fillet may be inspected
optically, eliminating the need for slow and
expensive X-ray inspection during PCB
assembly.
The D24V0L1B2LPSQ will withstand air
discharges and contact electrostatic discharges
of ±20kV.

Tiny, low-power 32-bit MCUs offer
rich set of peripheral functions
ATMEL
The new Atmel
®
SMART
™
SAM D10 and
SAM D11 microcontrollers, which have
an ARM
®
Cortex
®
-M0+ core, combine
flexibility and ease of use with low power
consumption and a compact package.
The tiny devices, which offer 8-16kbytes of
Flash memory and 4kbytes of SRAM, are
available in 14- or 20-pin SOIC packages and
a 24-pin QFN, which has a footprint of just
4mm x 4mm. Operating at a maximum clock
speed of 48MHz, these MCUs have a current
requirement of <70µA/MHz.
Both the SAM D10 and SAM D11 offer a
rich selection of peripherals integrated in the
chip. These include Full-speed USB with no
requirement for a crystal, a peripheral touch
controller which requires no external
components, a 12-bit ADC with gain stage, a
six-channel DMA controller, a 10-bit DAC, and
timers/counters for control applications.
All three packages use just two pins for
power; the Reset pin can be configured as a
general-purpose I/O.
Atmel has provided for easy migration
between SAM D series MCUs: they are code-
and pin-compatible, making it easy for
designers to extend or reduce the functionality
of an existing design as required.
All devices have accurate and low-power
external and internal oscillators. All oscillators
can be used as a source for the system clock.
Different clock domains can be independently
configured to run at different frequencies,
enabling power saving by running each
peripheral at its optimal clock frequency, and
thus maintaining a high core frequency while
reducing power consumption.

Small UV sensor fits space constraints of
wearable devices
VISHAY
Vishay Intertechnology has released an
integrated ultra-violet (UV) light sensor
featuring Filtron
™
UV technology, which
provides for both high sensitivity to UV
light and excellent linearity.
The Vishay Semiconductors
VEML6070, which combines a
photo-diode and a signal-
processing IC in a compact
2.35mm x 1.8mm x 1.0mm
surface-mount package, converts
measurements of solar UV light
intensity to a digital read-out.
It may be used for UV detection
in products such as smartphones,
fitness wristbands, flame
detectors and weather stations.
The sensor saves space by
integrating the circuitry needed for
these applications into one
compact unit.
A robust refresh-rate setting helps the system
designer to lower costs and simplify the circuit
by eliminating the need for an external low-
pass (resistor-capacitor) filter. The VEML6070
offers high resolution and excellent
performance under long-term solar UV
exposure.
The built-in photo-diode is sensitive to light
at wavelengths between 280nm and 400nm;
peak sensitivity is at 355nm. The sensor is
immune to the flicker from fluorescent lights.
Vishay has provided the VEML6070 with a
software setting that cuts typical power
consumption to 1µA in Shut-down mode. Its
output is highly stable over a temperature
range of -40°C to 85°C thanks to a
temperature-compensation scheme
implemented in the chip.

New optocouplers with high operating voltage
suit SiC and GaN power ICs
AVAGO TECHNOLOGIES
Avago Technologies has announced
two new series of gate-drive
optocouplers, which protect and drive
fast-switching power semiconductors
that are made of Silicon Carbide (SiC)
or Gallium Nitride (GaN) material.
The ACPL-P347 and -W347 are 1.0A gate-
drive optocouplers, and the ACPL-P349 and
-W349 are 2.5A devices.
These new parts support a wide gate
operating-voltage range up to as
high as 30V. This new higher gate-
drive capability means that they can
be used with the latest generation of
high-power SiC and GaN MOSFETs and
IGBTs, which are becoming increasingly
popular in industrial applications because they
support high switching frequencies and
operate at very high efficiency.
The ACPL-P/W347 and ACPL-P/W349 are
also notable for their very high-speed operation.
Propagation delay is rated at a maximum of
110ns; the propagation-delay difference is a
maximum of 50ns. Both rise and fall times are
typically 10ns, at 15V and a 50% duty cycle.
In addition, the gate-drive optocouplers
feature a high minimum common-mode
rejection figure of 50kV/µs, which is higher
than that of comparable gate-drive
optocouplers produced by competing
suppliers.
The maximum working insulation voltage, in
accordance with IEC/EN/DIN EN 60747-5-5, is
rated at 891V for the ACPL-P347/349, and at
1,140V for the ACPL-W347/349.
