SCP1000 Series
Interface Options
Communication interface is pre-programmed in the factory and it can be either SPI (Serial Peripheral
Interface) or I2C (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 I2C
interface is slave-only half duplex two-wire interfa ce a v ailable on SDA and SCL pins.
Interface Options
The SCP1000 Pressure sensor has 4 normal operation modes plus power down mode.
Mode Pressure measurement Resolution Output data refresh rate
High resolution Continues 17 bits 1.8 Hz
High speed Continues 15 bits 9 Hz
Ultra low power Periodical 15 bits Approximately 1 Hz
Low power External trigger 17 bits or 15 bits
Power Down Activated thro ugh PD pin
Electrical Connections
The SCP1000 pressure sensor supports two communication interfaces, SPI and I2C. Appropri ate
communication interfa ce i s pre -programmed in the factory.
