sors (Figure 5). It provides a wide dynamic
range and an exceptional signal-to-noise
ratio (SNR) for vibration analysis. In addi-
tion, it enables noise-emission detection and
current analysis in motors to avoid over-
heating. SmartMesh communication enables
low-power wireless communications. The
board offers the ability to configure warning
and alarm levels for each sensor. A compact
form factor and CE and FCC certification
round out the features.
At the heart of the system is an

technology. The MCU also has a collection of
digital peripherals, SRAM and built-in flash
memory, and an analog subsystem that pro-

capabilities. An analog-to-digital conversion
(ADC) subsystem is provided with a 12-bit
successive approximation register (SAR) ADC
and a 1.8-Msps, eight-channel converter for
data acquisition (Figure 6).
The Arm Cortex-M4F processor, with up to
52-MHz performance and 512 KB of built-in
flash with error correction code (ECC), offers
an optional 4-KB cache for less active power
and 128 KB of system SRAM with parity. CO-CREATING
