SCP1000 Series
Interface Options
Communication interface is pre-programmed in the factory and it can be either SPI (Serial Peripheral
Interface) or I 2 C (Inter-Integrated Circuit). The SPI interface is a full duplex 4 wire interface and the
connection between the MCU and SCP1000 is achieved using MOSI, MISO, SCK and CSB. The I 2 C
interface is slave-only half duplex two-wire interface available on SDA and SCL pins.
Interface Options
The SCP1000 Pressure sensor has 4 normal operation modes plus power down mode.

Electrical Connections
The SCP1000 pressure sensor supports two communication interfaces, SPI and I 2 C. Appropriate
communication interface is pre-programmed in the factory.
