FPS Series Pressure Sensor
SPI - SERIAL PERIPHERAL INTERFACE
Page 8
Introduction
The FPS serial interface is a high-speed data input
and output communication port that is asynchronous
to the internal conversion cycle. The serial interface
operates in 3-wire SPI mode. In this setup, the MOSI
and MISO pins are tied together, forming a bidirec-
tional data line to the master microcontroller. The
remaining serial interface connections consist of chip
select (/CS) and serial clock (SCLK).
Care should be taken to ensure that the sensor is
properly connected to the master microcontroller.
Refer to the manufacturer's datasheet for more infor-
mation regarding physical connections.
Signal control
The serial interface is enabled by asserting /CS low.
The serial input clock, SCLK, is gated internally to
begin accepting the input data at MOSI, or sending
the output data on MISO. When /CS rises, the data
clocked into MOSI is loaded into an internal register.
Note: If SPI communication is not required (i.e. only
analog output is being used) pins 6 to 8 must be
connected to ground and pin 9 to Vs. Failure to do so
may result in damage to the sensor.
Note: It is important to adhere to the communication protocol in order to avoid damage to the Sensor.
Data read
When powered on, the sensor begins to continuous-
ly measure pressure. To initiate data transfer from
the sensor, the following three unique bytes must be
written sequentially, MSB first, to the MOSI pin (see
Fig. 1):

B10011000 Read data register
The entire 16 bit content of the FPS register is then
read out on the MISO pin, MSB first, by applying 16
successive clock pulses to SCLK with /CS asserted
low. Note that the value of the FPS is held at zero
for internal signal processing purposes. This is
below the noise threshold of the sensor and thus its
fixed value does not affect sensor performance and
accuracy.
From the digital sensor output the actual pressure
value can be calculated as follows:
So for a 1.0 inH2O sensor (FPSS250B...) with a
scale factor of 120 a digital output of 30,000 counts
(7530’h) calculates to a positive pressure of 1.0
inH2O. Similarly, a digital output of -30,000 counts
(8AD0’h) calculates to a negative pressure of -1.0
inH2O.
