POWER SUPPLY, VDD Operating voltage range 3.0 3.6 V Power Supply Current13 Normal mode, VDD = 3.3 V, µ ± σ 254 mA Sleep mode, VDD = 3.3 V 12.2 mA Power-down mode, VDD = 3.3 V 45 µA POWER SUPPLY, VDDRTC Operating voltage range 3.0 3.6 V Real-Time Clock Supply Current Normal mode, VDDRTC = 3.3 V 13 µA 1 Accuracy specifications assume calibration of accelerometers and magnetometers to address sensor drift and local influences on magnetic fields. 2 The repeatability specifications represent analytical projections that are based off of the following drift contributions and conditions: temperature hysteresis (−40°C to +85°C), electronics drift (High-Temperature Operating Life test: +110°C, 500 hours), drift from temperature cycling (JESD22, Method A104-C, Method N, 500 cycles, −40°C to +85°C), rate random walk (10 year projection), and broadband noise. 3 Bias repeatability describes a long-term behavior, over a variety of conditions. Short-term repeatability is related to the in-run bias stability and noise density specifications. 4 The relative error assumes that the initial error, at 25°C, is corrected in the end application. 5 Specification assumes a full scale (FS) of 1000 mbar. 6 The digital I/O signals use a 3.3 V system. 7 RST and CS pins are connected to the VDD pin through 10 kΩ pull-up resistors. 8 Endurance is qualified as per JEDEC Standard 22, Method A117, and measured at −40°C, +25°C, +85°C, and +125°C. 9 The data retention specification assumes a junction temperature (TJ) of 85°C as per JEDEC Standard 22, Method A117. Data retention lifetime decreases with TJ. 10 These times do not include thermal settling, internal filter response times, or EKF start-up times (~825 ms), which may affect overall accuracy, with respect to time. 11 The RST line must be in a low state for at least 10 μs to assure a proper reset initiation and recovery. 12 The device functions at clock rates below 0.7 kHz, but at reduced performance levels. 13 Supply current transients can reach 600 mA during start-up and reset recovery.
