Elmos Semiconductor AG: SMI Extends Its AccuStableTM Product Portfolio to Lower Pressures

With two new product series, pressure ranges from 0.3 to 30 psi are now available

SMI (Silicon Microstructures, Inc.), a subsidiary of Elmos, has launched the SM5221 and SM6221 fully digital, low pressure MEMS sensor series as part of the SM5000 and SM6000 families. Covering pressure ranges from 0.3 to 2.0 psi (21 to 140 cmH₂O), the sensors have a better than 1% initial accuracy and less than 1% total output shift over life (1% shift over 1000hr HTOL). The AccuStable(TM) brand thus guarantees they are among the most stable low-pressure sensors available. Only products that have an extraordinary accuracy with a long-time stability are allowed to have this high quality label. Combining the two new series with the SM1221 and SM4221 series released earlier this year, SMI's AccuStable(TM) system solutions cover pressure ranges from 0.3 to 30 psi.

The SMX221 series offer gauge, differential and asymmetric calibration, 14- bit digital I²C output and 1% total accuracy. Combining the pressure sensor with a signal-conditioning ASIC in a single package simplifies the user experience. The pressure sensor can be mounted directly on a standard printed circuit board and a high level, calibrated pressure signal can be acquired from the digital interface. This eliminates the need for additional circuitry, such as a compensation network or microcontroller containing a custom correction algorithm. These products come in a JEDEC standard SOIC-16 package and are shipped in sticks or tape & reel.

SMI's pressure sensor families are developed with special focus on the following markets: Medical (e.g. Medical Instrumentation and Equipment for Medical Treatment), Industrial (e.g. Industrial Automation and Controls), Consumer (e.g. Home Appliances and White Goods), Aerospace (e.g. Cabin Pressure and Cockpit Instrumentation) and HVAC.

The digital-output pressure sensors were developed and are being manufactured in a state-of-the-art pressure transducer and CMOS facility. They produce digital, fully signal conditioned and multi-order pressure sensor output. Temperature compensation is from -20 to +85 C. Compensated pressure ranges are fully customizable from 0.3 to 30 psi, and can be gauge, differential or custom pressure ranges. The digital interface uses I²C protocol, and both vertical and horizontal porting options are available.

SMI is a member of the worldwide Elmos Semiconductor Group, offering proven solutions to a range of industries, based on application-specific ICs, sensors and complete microsystems. SMI is an ISO/TS16949:2009 certified premier developer and manufacturer of MEMS-based pressure sensors for a broad range of markets, with over 25 years of experience. SMI's design, production and quality control processes have enabled it to develop both the most sensitive and smallest MEMS pressure sensors available on the market today.
