The SMP480 belongs to a new family of digital pressure sensors. The main application for this device is the barometric air pressure measurement in diesel or gasoline engine management control units.
The new barometric pressure sensor SMP480 is designed for a standard pressure range of 40 kPa…115 kPa. It is composed of a 2-chip-architecture. The sensor element is manufactured with the Bosch APSM (Advanced Porous Silicon Membrane) process. The APSM technology allows producing a stable single-crystalline membrane with a surface micro-mechanic process.

The pressure signal is amplified and temperature compensated by a separate ASIC manufactured in a highly integrated CMOS technology. The digital signal evaluation enables elaborate self tests. Additionally to the pressure signal the sensor provides a temperature signal.

With these technologies we realized a very robust design and achieved high sensor accuracy. The sensor is protected against short circuit and ESD and is also RoHS compliant.
