ST invites Embedded World 2016 attendees to participate
in on-booth technical conferences or go into more depth
on products and tools during practical workshops running
throughout the exhibition. ST will give away hundreds
of valuable and easy-to-use development boards and
other prizes, including BB-8™ by Sphero, an app-enabled
Droid™ powered by the STM32F3 ARM® Cortex®-M4
microcontroller, during various activities.
Among the demonstrations planned for Embedded World
attendees are:
The newest members of the STM32 ARM Cortex-M MCU
family, including new 14-pin STM32L0 devices, smaller
derivatives of the STM32L4, and extensions of the STM32F4
and STM32F7 series;
A member of the LoRa® Alliance, ST will demonstrate the
LoRa technology1 on STM32 MCUs and distribute LoRa
combo packs (STM32L0 Nucleo + SX1276MB1LAS shield
from Semtech) to interested attendees;
Application solutions around the STM32 including
connectivity, graphics, motor control, ARM mbed™ OS,
Apple HomeKit™, and more;
The STM32 Open Development Environment, which provides
a flexible, easy, and affordable way to develop innovative
devices and applications;
The full NFC portfolio, including tags, dynamic tags, readers,
and transceivers;
A new security module for securing connected devices;
Solutions that include wireless charging, new innovative
sensors, wireless connectivity, MEMS microphones, and
micro-power analog, to complement embedded designs;
Flightsense™ sensor family for ranging, user detection, and
gesture control;
Embedded solutions for automotive applications that include
the first Power Architecture™ MCU with ISO CAN FD
(Flexible Data Rate) and the SPC5Studio microcontroller
development environment demonstrated on the smallest
ASIL-D microcontroller device (SPC57);
Teseo III single-chip standalone positioning ICs capable of
receiving signals from multiple Global Navigation Satellite
Systems.

Maxim’s Defibrillation and ESD Protection
Device Safeguards Medical Applications with 100x
Less Leakage Current
Targeting medical equipment such as defibrillators as well
as ECG diagnostics and monitoring systems, the MAX30034
defibrillation protection device from Maxim Integrated
Products, Inc. (NASDAQ: MXIM) protects against defibrillation
pulses and electrostatic discharge (ESD). Compared to
existing approaches and components, it simplifies design,
provides > 75% space savings, and trims the bill of materials,
all while significantly improving performance.
Designers of defibrillators and ECGmonitors face a challenge,
as their ECG input amplifiers must withstand high-voltage
pulses for cardiac resuscitation. These pulses can easily
damage the sensitive electronic circuitry which captures
the millivolt level heart signals. Preventing this damage has
required a three-layer, multi-component approach combining
a per-channel gas-discharge tube (GDT) and/or transient-
voltage suppression (TVS) device, as well as ESD-protection
diodes. Further, leakage current (a critical parameter) is
relatively high, at about 1-2nA.
Maxim’s four-channel MAX30034 defibrillation protection
device uses an innovative topology from an advanced
semiconductor process to absorb and harmlessly redirect
these high-energy pulses away from sensitive circuitry. This
small and robust device needs only two external pairs of
resistors for each channel to provide design simplicity, smaller
overall size, and lower leakage current. The MAX30034
replaces the primary-level GDTs and/or TVSs, as well as
secondary-level ESD diodes which are the conventional
solutions for mandated circuit protection. The device can
withstand over 100,000 defibrillation pulses without failure
