SP100 Series
Compensated Pressure Sensors
The SP100 pressure sensors are calibrated and digitally compensated silicon piezoresistive sensors with SPI
interface. In addition to pressure these sensors provides temperature and supply voltage measurements. Each
sensor has a unique electronic sensor ID, and has a built in self diagnosis system. SP100 sensors can easily be
used in a broad range of applications and interfaces directly to a micro controller without the need of any additional
components.
SP100 series of sensors has excellent media compatibility due to a patented bulk micromachined triple stack sensor
die design, utilizing buried piezoresistive elements and backside media access to pressure diaphragm. With this
design the internal connectors and piezoresistive elements of the pressure bridge are isolated from the
measurement media. This isolation is of great importance in terms of stability and reliability of the sensor over a very
long lifetime.
The SP100 pressure sensor design has been proven in harsh environment applications during a period of more than
10 years, making these sensors ideal choices for demanding applications where simple solutions are needed to
quickly implement reliable and accurate pressure measurements.
SP100-1 and SP100-2 belongs to the lower pressure range of SP100 sensors.

1.2 Overview
SP100 is an integrated MEMS pressure sensor designed for air pressure measurements. The sensor has a digital
interface designed for use in microcontroller applications. SP100 is housed is a 14 pin small outline package, and
requires no external components. SP100-1T and SP100-2T have a tube connection option (for ‘T’ version
sensors).

The component will also withstand standard reflow soldering, accumulated time < 2.5 hours.
Less than 3 min.
Accumulated time at 150°C not to exceed 500hours to avoid permanent damage. Solder ability may be affected with less exposure.
According to AEC-Q100-002 Rev. C or JESD22-A114 Rev. F

Prolonged exposure to values between recommended operating conditions and absolute maximum ratings might
affect the performance and reliability of the device.
5 Wake-Up and Reset Outputs
The product provides two outputs, which may be used to interrupt or reset a microcontroller. Each output provides a
pulse at regular intervals. The “wake-up and reset” are active low outputs. The Wake Up period typical value is
programmable from 1 to 256 seconds, in 1 second intervals.

Notes:
1) See text describing oscillators below.
The product has two oscillators: One low-power oscillator, which runs at about 2.5 kHz and is used for interval
timing, and a 2 MHz oscillator used for measurements and data transmission. Due to its very low current
consumption, the low-power oscillator is sensitive to temperature and supply voltage variation. To keep the interval
lengths constant under different conditions, the low-power oscillator is compared to the 2 MHz oscillator during each
measurement, and a correction is applied to the interval count. This operation is called an auto calibration. The
stability of the interval depends on the change in temperature or supply voltage since the last measurement.
6 Serial Interface
The SPI interface is the communication protocol to the external microcontroller. This maximum serial clock frequency
is 500 kHz.
The SPI consists of a shift register, a command latch and failure latches, and encoder/decoder logic.
