SP270252560XTMA1

Board Mount Pressure Sensors TPMS&INERTIA

Description:

The SP27 sensor is designed for measuring pressure in PMS applications. With its microcontroller and integrated peripherals, the SP27 is a single package solution, requiring very few external components. Pressure and temperature measurements are controlled by software. The microcontroller formats and processes the measured data and passes them to the PMS. An intelligent wake-up mechanism reduces power consumption, while an interval timer controls the timing of measurements. The circuitry can be programmed to wake up at regular intervals. An external wakeup source can also be connected to a general purpose input/ output GPIO interface. The integrated microcontroller is instruction-set-compatible with a standard 8051 processor. Integrated on-chip Flash memory can be used to store a customer-specific application program code and is also used to store an unique ID number and the calibration data for the sensors. Additional on-chip ROM memory is available and contains ROM library functions developed by that cover standard tasks used by the application.
