XEMICS S.A., specializing in short-range wireless connectivity products,
today announced the release of the XE88LC05 Sensing Machine, a revolutionary
Data Acquisition System-On-Chip.
The XE88LC05 Data Acquisition chip includes a 16 + 10 bits ZoomingADC that directly reads any Wheatstone bridge sensor and 2 DACs. Suitable for pressure sensors, barometers, compass and other industrial and consumer products, this unique solution can be programmed to directly read any type of bridge sensors. The integrated MTP Flash memory, UART, numerous IO and the MCU makes it possible to realize a large variety of filtering and data processing functions. This programmable 16 + 10 bits Data Acquisition System-On-Chip uses less than 2 uA in standby mode and 300 uA/MHz
in active mode.
The XE88LC05 has all functions integrated on a single chip to build the electronics of an industrial pressure sensor. One integrated DAC is used to bias the sensing element. The ZoomingADC can apply a gain of 1000 to the sensing element's signal, and then convert the resulting signal with a resolution of 16 bits.
''The ZoomingADC can even cancel the sensing element's own offset to apply the maximum of gain without saturation,'' said Michel Chevroulet, Product Line Manager for the XE8000 series. ''And, all this without a single external component.''
Further data filtering and processing is done in the MCU with the integrated 1 clock-cycle multiplier. Additional asynchronous digital communication via the UART requires an external low cost 32 kHz crystal. The second DAC is often used to output an analog copy of the measured signal.
The ZoomingADC requires only 200 uA at 2.4 V for a 12 bit 8 kHz or a 16 bit 2 kHz data conversion, the full scale being programmed anywhere between 2.4 mV and 5 V. The MCU executes any instruction in 1 single clock cycle, and requires 300 uA/MHz. Any block can be set in sleep mode for very low-power operation.
Examples of applications that take profit of the XE88LC05
include industrial pressure sensors, barometers, solid state compasses, and
temperature monitors. Software examples and design tools are available from
www.xemics.com.
