Five Advantages
Redefining The Link Between Analog And Digital Worlds
RENESAS “Smart Analog”
A Smart Society is more convenient, eco-friendly, and safe.
Advancements in analog sensor technologies have enabled “smarter” devices and equipment. For example, we can
detect and measure the faintest hint of a dangerous gas, the identify a defective part in a fast moving production
conveyor, or the sense slightest seismic movement, all with more precision than ever before.
Renesas, a global leader of microcontrollers and analog technologies introduces Smart Analog technology that
redefines how these analog sensors link to the digital electronics world through a flexible, intelligent analog front end
(AFE) platform.
The Smart Analog platform is a reconfigurable analog front-end device that interfaces
to the most sophisticated sensors used in industrial, consumer, commercial and medical
applications. An intelligent software tool eliminates time consuming trial-and-error
rewiring of the circuit resulting in reduced time to market, lower system costs, and
reduced power consumption.

Building a Smart Society
With Smart Analog you can build an analog circuit development platform that lets you
quickly and flexibly respond to the ever-changing sensor needs of tomorrow's Smart
Society.
Smart Analog propels the creation of human interfaces that are more intuitive and user
friendly, economically viable ecosystems that meet the demands of the green society,
and robust security systems that function smoothly.

The MCU can also be used to reconfigure
the circuits according to the sensor being
developed. A single Smart Analog IC
handles all the different voltage, current
and differential output signals unique to
each type of sensor. Even if your
application includes a mixture of sensors,
a single Smart Analog chip can be
reconfigured in the set to provide the
functionality of multiple analog front end
circuits.

Clever functionality
All analog circuit configurations and characteristics can be changed and optimized by using
SA-Designer software and the MCU, reducing the design lead time by 3 to 8 months*. You can
also use the web simulator Renesas VA to perform all verification work from commercial
sensor selection before purchasing your Smart Analog to system verification, which can speed
up verification by up to 3 months*. Smart Analog allows you to develop your system faster and
more efficiently by accelerating all development processes, including adaptive simulation.

If the output gain of the sensor is the same as when the
sensor was first installed, the MCU stops detecting the sensor
output once it falls below the detection threshold. A drop in
the steady-state output is identified before the MCU stops
detecting the sensor output even when the luminance is within
the detection range.

Previously, trimming had to be performed
manually during manufacture of the
sensor equipment to absorb variations in
sensor characteristics. But with Smart
Analog, the configuration and
characteristics of the analog circuits are
controlled automatically by the MCU.
Smart Analog is also field programmable,
allowing long-term sensor drift to be
automatically corrected and repaired.
This prolongs the life of your system and
raises its added value.
The sensor becomes dirty and its
characteristics drift over time, causing a drop
in sensitivity.

Luminance
If the sensor output falls below the initial value, the output gain
is raised programmably so that the MCU maintains its
detection performance. This means that if the luminance is
within the detection range, it will be detected normally.
