The company said that it provides customer specified communication via five general purpose I/O pins and a 2 channel LF receiver supporting wireless command and data reception, which can be used for configuration and device wake up.
It has features such as electronic ID, temperature measurement, supply voltage measurement, diagnostics and an optional 125g on-chip accelerometer. A set of ROM library functions simplifies code development.
The company added that a fully autonomous pressure, acceleration and temperature measurement system is created by adding a battery, an RF transmitter IC and an antenna. Due to the ultra low power architecture the sensor is ideal for battery operation.
Stand-by current is 0.3µA and a low noise 11-bit measurement requires 4µAs. The SP300-series is offered in 0.5 to 16 bar FS ranges and in a 14 pin plastic SOIC package with optional pressure tube connection.
Carsten Fongen, sales manager of Sensonor Technologies, said: ”Launch of SP300 is a milestone in history of MEMS pressure sensors; capable of operating in the most demanding environments, using a patented bulk micro machined triple stack design with backside media access, and functional over the full -40 to +125 degree centigrade temperature range with survival even up to +175°C for shorter periods.
”The exceptional multifunction makes SP300 ideal for applications with distributed points of measurement; system architecture can be realized with a minimum of components and without wiring each unit to a central control; this provides system designers full flexibility and secures the lowest system cost. Due to the extreme low power a tiny coin type battery provides enough energy for years and years of operation.”
