Product Brief
SP27
General Sensor for Pressure Monitoring Systems (PMS)
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 Infineon) that cover standard tasks used
by the application.
