New Strain Gauge Application Platform From Intersil and Freescale Delivers High Precision Measurement for 32-Bit Data

New Strain Gauge Application Platform From Intersil and Freescale Delivers High 
Precision Measurement for 32-Bit Data Processing 
Introduced by Future Electronics for Customers Who Require Fast, Low
Power Solutions 
MILPITAS, CA -- (Marketwire) -- 02/22/13 --  Intersil Corporation
(NASDAQ: ISIL), a leader in the design and manufacture of
high-performance analog, mixed-signal and power management
semiconductors, has joined Freescale Semiconductor to develop a new
thermocouple and strain gauge application solution that delivers
excellent high precision measurement coupled with fast, low power
data processing for advanced designs.  
The new board features two sensor applications using Intersil's
precision and power products coupled with the Freescale Kinetis L
series microcontroller featuring a Cortex M0+ core. The demonstration
platform consists of two separate boards -- the Intersil precision
and power products application board and the FRDM-KL25Z Freescale
Freedom development platform. 
The thermocouple design uses a K-type thermocouple with cold junction
compensation. This design uses Intersil's ISL28134 zero drift
amplifier, ISL21090 voltage reference, ISL22317 DCP, the ISL26102
24-bit delta sigma converter and the Freescale KL25Z MCU, featuring
128 KB flash and 16 KB SRAM onboard. 
Strain Gauge Design as Bridge Solution 
The strain gauge design, which is also part of the demo, is a bridge
solution that is able to extract a small sensor signal from a high
voltage common mode signal of 10V or higher. The design uses
Intersil's 40V ISL28617 instrumentation amplifier, ISL21090 voltage
reference, the ISL26102 24-bit delta sigma converter and the
Freescale microcontroller for data acquisition and processing of
measurement data, as well as using the onboard USB ports to make the
data available, for example, a display.  
The demo is powered from a mini USB connection on the Freescale
Freedom development platform, providing the 5V to generate the
required +12V, +10V, and +/-5V supplies for the demo. The 5V supply
is regulated down to a clean 3.3V supply using Intersil's ISL80101
high performance LDO, boosted then to +12V using Intersil's ISL97516
step-up regulator. The other voltages are generated by an ICL7660
charge pump and an ISL80138 linear regulator. 
The thermocouple temperature or applied strain can be monitored using
a GUI on the computer powering the demo through the mini USB cable.
The display shows real time data in either numerical or a graphical
representation of the temperature or strain measurement. 
Both designs perfectly complement Freescale's 32-bit Kinetis L series
MCUs by the exceptional noise performance of a 24-bit delta sigma
converter featuring a 3rd-order modulator, which provides up to 21.5
bit noise-free performance. The Kinetis L series combine the
exceptional energy-efficiency and ease-of-use of the new ARM
Cortex-M0+ processor with the performance, peripheral sets,
enablement and scalability of the Kinetis 32-bit MCU portfolio. The
Kinetis L series frees power-critical designs from 8- and 16-bit MCU
limitations by combining dynamic and stop currents with superior
processing performance, a broad selection of on-chip flash memory
densities and extensive analog, connectivity, and HMI peripheral
Christopher Koch, Technical Director at Future Electronics, said:
"This new application board was initiated by Future Electronics to
add value to all customers that require high precision measurement in
combination with fast and low power data processing with the latest
32-bit Cortex M0+ technology. Intersil and Freescale both offer state
of the art technology for our customers in the industrial, medical
and sensor market segments -- they will like this solution."
