1 / 80 page  This is information on a product in full production. October 2017 DocID030988 Rev 2 1/80 ISM303DAC High-performance, low-power, compact 3D accelerometer and 3D magnetometer module Datasheet - production data Features 3 magnetic field channels and 3 acceleration channels Up to ±50 gauss magnetic dynamic range ±2/±4/±8/16 g selectable acceleration full scales Dynamic switching between high-resolution, high-frequency and low-power modes 16-bit data output SPI / I2C serial interfaces Analog supply voltage 1.71 V to 1.98 V Programmable interrupt generators for free- fall, motion and magnetic field detection Embedded self-test both for the accelerometer and magnetometer Embedded 256-level FIFO Embedded temperature sensor ECOPACK®, RoHS and “Green” compliant Applications Dual mode anti-tampering in smart meters Antenna pointing Motion tracking Robotics and appliances Positioning and navigation systems Positional and distance sensor Description The ISM303DAC is a high-performance, low- power system-in-package featuring a 3D digital linear acceleration sensor and a 3D digital magnetic sensor. The ISM303DAC has user-selectable linear acceleration full scales of ±2g/±4g/±8g/ 16 g and is capable of measuring accelerations with output data rates from 1 Hz to 6400 Hz. The device has a magnetic field dynamic range of up to ±50 gauss with output data rates from10 Hz to 150 Hz. The ISM303DAC includes an I2C serial bus interface that supports standard, fast mode, fast mode plus, and high-speed (100 kHz, 400 kHz, 1 MHz, and 3.4 MHz) and an SPI serial standard interface. The ISM303DAC has an integrated 256-level first- in, first-out (FIFO) buffer for the accelerometer data which can be used to limit the intervention of the host processor. The embedded self-test capability allows the user to check the functioning of the sensor in the final application. The system can be configured to generate an interrupt signal for free-fall, motion detection and magnetic field detection. The magnetic and accelerometer blocks can be enabled or put into power-down mode separately. The ISM303DAC is available in a plastic land grid array package (LGA) and is guaranteed to operate over an extended temperature range from -40 °C to +85 °C. Table 1.
