SCP1000 Barometric Pressure Sensor The SCP1000-D01 is a great IC - now you can play with it! This is a simple breakout board bringing the SPI interface pins to a 0.1" header. Please note: This is the ASIC rev B (IC label 'P01'). The SCP1000 rev C has not yet been released to market to date. We will stock the newer revision once it is made available by VTI. The SCP1000 is the very first absolute pressure sensor on the market to use MEMs technology to grant 17-bit resolution. Under ideal conditions, this sensor can detect the pressure difference within a 9cm column of air. VTI's SCP1000-D01 digital absolute pressure sensors are intended for barometric pressure measurement and altimeter applications for 30kPa...120kPa and -20°C...70°C measuring ranges. The pressure and temperature output data is calibrated and compensated internally and the communication between the SCP1000 and its host micro-controller is realized using an SPI interface. SCP1000 is comprised of a VTI's 3D-MEMS capacitive sensing element, a dedicated low power CMOS interface ASIC with on-chip calibration memory, 4 preset measuring modes and a LCP (Liquid Crystal Plastic) MID (Molded Interconnect Device) housing. The component is a surface mountable device incorporating a circular vertical wall for easy waterproof sealing. Four user selectable measuring modes combine 17-bit resolution (9cm of air column) with low or ultra-low power consumption, or alternatively 15-bit resolution (18cm of air column) with high speed data read (9Hz) or less than 5µA and power consumption. For example, at Low Power mode, the SCP1000 has an overall resolution of 2 Pa (15cm of air column) and a power consumption of 3.5µA. This unit comes in a newly developed RoHS compliant plastic housing. Normal hot-air rework will destroy this sensor so we highly recommend this breakout board for prototyping.
