Microchip Technology Inc. (NASDAQ: MCHP), a leading provider of
microcontroller, mixed-signal, analog and Flash-IP solutions, today announced
from the Embedded World conference in Germany its BodyCom™ technology, which
provides designers with the world’s first framework for using the human body
as a secure communication channel. Compared to existing wireless methods,
BodyCom technology provides lower energy consumption, while further increasing
security via bidirectional authentication. Because no RF antennas are
required, BodyCom technology allows for simpler circuit-level designs and a
lower bill of materials (BOM). All of this is enabled by the BodyCom
Development V1.0 Framework, which is supplied through free software libraries
that work on all of Microchip’s more than 900 8-, 16- and 32-bit PIC^®

BodyCom technology is activated by capacitively coupling to the human body.
The system then begins communicating bidirectionally between a centralized
controller and one or more wireless units. There are a broad range of
applications where secure wireless communication is essential, and there is no
more secure channel than the human body. This is especially true when you add
bidirectional authentication that supports advanced encryption, such as
KeeLoq^® technology and AES. For example, BodyCom technology helps prevent the
“Relay Attack” problem that is typical in automotive passive-keyless-entry
security systems.

Most secure, short-range communication designs are battery powered and highly
cost constrained. BodyCom technology significantly increases battery life by
eliminating the need for a wireless transceiver or high-power inductive
fields. It also simplifies development and lowers BOM costs by not only making
antenna design unnecessary, but also by using a low-frequency framework with a
common microcontroller and standard AFE frequencies (125 kHz and 8 MHz)—no
external crystals are needed. And, because it complies with FCC Part 15-B for
radiated emissions, BodyCom technology eliminates the cost and complexity of

Additional example applications include Access Control (security systems,
home/industrial door locks, pet doors); Personal Safety & Security (equipment
access/disable, power tools, firearms, computer systems); Medical (patient
monitoring, hospital-room access, equipment tracking); and Consumer (profile
management for gaming consoles and exercise equipment).

“BodyCom technology provides a more secure, low-cost and easy method for
implementing short-range, low-data-rate wireless communication with the lowest
power consumption,” said Steve Drehobl, vice president of Microchip’s MCU8
Division. “Our BodyCom Development Framework is available via free download,
and it works with any of our PIC microcontrollers, which presents a very low
barrier of entry for designers.”

Development Support

To further enable development and speed time to market, Microchip is also
announcing the BodyCom Development Kit (part # DM160213). This kit is
available today for $149, and comes with a central controller unit and two
wireless mobile units.

The free BodyCom Development V1.0 Framework is also available today, and comes
with a communication library, application code examples and a development GUI
for use on personal computers. Additionally, application note AN1391, which
provides an introduction to BodyCom technology, is available at
