Description

The LSM6DS3H is a system-in-package featuring a 3D

digital accelerometer and a 3D digital gyroscope

performing at 1.1 mA (up to 1.6 kHz ODR) in high-

performance mode and enabling always-on low-power

features for an optimal motion experience for the

consumer.

The LSM6DS3H supports main OS requirements,

offering real, virtual and batch sensors with 4 kbyte

FIFO + flexible 4 kbyte (FIFO or programmable) for

dynamic data batching.

The LSM6DS3H gyroscope supports both OIS/EIS

applications. The device can be connected to the

camera module through a dedicated auxiliary SPI

(Mode 3) while flexibility for the primary interface is

available (I2C/SPI).

ST’s family of MEMS sensor modules leverages the

robust and mature manufacturing processes already

used for the production of micromachined

accelerometers and gyroscopes.

The various sensing elements are manufactured using

specialized micromachining processes, while the IC

interfaces are developed using CMOS technology that

allows the design of a dedicated circuit which is

trimmed to better match the characteristics of the

sensing element.

The LSM6DS3H has a full-scale acceleration range of

±2/±4/±8/±16 g and an angular rate range of

±125/±250/±500/±1000/±2000 dps.

High robustness to mechanical shock makes the

LSM6DS3H the preferred choice of system designers

for the creation and manufacturing of reliable products.

The LSM6DS3H is available in a plastic land grid array

(LGA) package.

LSM6DS3H Overview

108

1 Overview

The LSM6DS3H is a system-in-package featuring a high-performance 3-axis digital

accelerometer and 3-axis digital gyroscope.

The integrated power-efficient modes are able to reduce the power consumption down to

1.1 mA in high-performance mode, combining always-on low-power features with superior

sensing precision for an optimal motion experience for the consumer thanks to ultra-low

noise performance for both the gyroscope and accelerometer.

The LSM6DS3H delivers best-in-class motion sensing that can detect orientation and

gestures in order to empower application developers and consumers with features and

capabilities that are more sophisticated than simply orienting their devices to portrait and

landscape mode.

The event-detection interrupts enable efficient and reliable motion tracking and contextual

awareness, implementing hardware recognition of free-fall events, 6D orientation, tap and

double-tap sensing, activity or inactivity, and wakeup events.

The LSM6DS3H supports main OS requirements, offering real, virtual and batch mode

sensors. In addition, the LSM6DS3H can efficiently run the sensor-related features specified

in Android, saving power and enabling faster reaction time. In particular, the LSM6DS3H

has been designed to implement hardware features such as significant motion, tilt,

pedometer functions, timestamping and to support the data acquisition of an external

magnetometer with ironing correction (hard, soft).

The LSM6DS3H offers hardware flexibility to connect the pins with different mode

connections to external sensors to expand functionalities such as adding a sensor hub,

auxiliary SPI, etc. The application processor connection is supported by both SPI and I2C

interfaces for complete interface flexibility.

Up to 8 kbyte of FIFO [4 kbyte FIFO + flexible 4 kbyte (FIFO or programmable)] with

dynamic allocation of significant data (i.e. external sensors, timestamp, etc.) allows overall

power saving of the system.

Like the entire portfolio of MEMS sensor modules, the LSM6DS3H leverages the robust and

mature in-house manufacturing processes already used for the production of

micromachined accelerometers and gyroscopes. The various sensing elements are

manufactured using specialized micromachining processes, while the IC interfaces are

developed using CMOS technology that allows the design of a dedicated circuit which is

trimmed to better match the characteristics of the sensing element.

The LSM6DS3H is available in a small plastic land grid array (LGA) package of

2.5 x 3.0 x 0.83 mm to address ultra-compact solutions.

Embedded low-power features LSM6DS3H

16/108 DocID028370 Rev 5

2 Embedded low-power features

The LSM6DS3H has been designed to be fully compliant with Android, featuring the

following on-chip functions:

8 kbyte data buffering

– 4 kbyte FIFO + flexible 4 kbyte (FIFO or programmable)

– 100% efficiency with flexible configurations and partitioning

– possibility to store timestamp

Event-detection interrupts (fully configurable):

– free-fall

– wakeup

– 6D orientation

– tap and double-tap sensing

– activity / inactivity recognition

Specific IP blocks with negligible power consumption and high-performance:

– pedometer functions: step detector and step counters

– tilt (Android compliant, refer to Section 2.1: Tilt detection for additional info

– significant motion (Android compliant)

Sensor hub

– up to 6 total sensors: 2 internal (accelerometer and gyroscope) and 4 external

sensors

Data rate synchronization with external trigger for reduced sensor access and enhanced

fusion

2.1 Tilt detection

The tilt function helps to detect activity change and has been implemented in hardware

using only the accelerometer to achieve both the targets of ultra-low power consumption

and robustness during the short duration of dynamic accelerations.

It is based on a trigger of an event each time the device's tilt changes by an angle greater

than 35 degrees from the start position.

The tilt function can be used with different scenarios, for example:

a) Trigger when phone is in a front pants pocket and the user goes from sitting to

standing or standing to sitting;

b) Doesn’t trigger when phone is in a front pants pocket and the user is walking,

running or going upstairs.

4.6 Terminology

4.6.1 Sensitivity

Linear acceleration sensitivity can be determined, for example, by applying 1 g acceleration

to the device. Because the sensor can measure DC accelerations, this can be done easily

by pointing the selected axis towards the ground, noting the output value, rotating the

sensor 180 degrees (pointing towards the sky) and noting the output value again. By doing

so, ±1 g acceleration is applied to the sensor. Subtracting the larger output value from the

smaller one, and dividing the result by 2, leads to the actual sensitivity of the sensor. This

value changes very little over temperature and over time. The sensitivity tolerance describes

the range of sensitivities of a large number of sensors.

An angular rate gyroscope is device that produces a positive-going digital output for

counterclockwise rotation around the axis considered. Sensitivity describes the gain of the

sensor and can be determined by applying a defined angular velocity to it. This value

changes very little over temperature and time.

4.6.2 Zero-g and zero-rate level

Linear acceleration zero-g level offset (TyOff) describes the deviation of an actual output

signal from the ideal output signal if no acceleration is present. A sensor in a steady state on

a horizontal surface will measure 0 g on both the X-axis and Y-axis, whereas the Z-axis will

measure 1 g. Ideally, the output is in the middle of the dynamic range of the sensor (content

of OUT registers 00h, data expressed as 2’s complement number). A deviation from the

ideal value in this case is called zero-g offset.

Offset is to some extent a result of stress to MEMS sensor and therefore the offset can

slightly change after mounting the sensor onto a printed circuit board or exposing it to

extensive mechanical stress. Offset changes little over temperature, see “Linear

acceleration zero-g level change vs. temperature” in Table 3. The zero-g level tolerance

(TyOff) describes the standard deviation of the range of zero-g levels of a group of sensors.

Zero-rate level describes the actual output signal if there is no angular rate present. The

zero-rate level of precise MEMS sensors is, to some extent, a result of stress to the sensor

and therefore the zero-rate level can slightly change after mounting the sensor onto a

printed circuit board or after exposing it to extensive mechanical stress. This value changes

very little over temperature and time.

5 Functionality

5.1 Operating modes

The LSM6DS3H has three operating modes available:

only accelerometer active and gyroscope in power-down

only gyroscope active and accelerometer in power-down

both accelerometer and gyroscope sensors active with independent ODR

The accelerometer is activated from power down by writing ODR_XL[3:0] in CTRL1_XL

(10h) while the gyroscope is activated from power-down by writing ODR_G[3:0] in

CTRL2_G (11h). For combo mode the ODRs are totally independent.

5.2 Gyroscope power modes

In the LSM6DS3H, the gyroscope can be configured in four different operating modes:

power-down, low-power, normal mode and high-performance mode. The operating mode

selected depends on the value of the G_HM_MODE bit in CTRL7_G (16h). If G_HM_MODE

is set to ‘0’, high-performance mode is valid for all ODRs (from 12.5 Hz up to 1.6 kHz).

To enable the low-power and normal mode, the G_HM_MODE bit has to be set to ‘1’. Low-

power mode is available for lower ODR (12.5, 26, 52 Hz) while normal mode is available for

ODRs equal to 104 and 208 Hz.

5.3 Accelerometer power modes

In the LSM6DS3H, the accelerometer can be configured in four different operating modes:

power-down, low-power, normal mode and high-performance mode. The operating mode

selected depends on the value of the XL_HM_MODE bit in CTRL6_C (15h). If

XL_HM_MODE is set to ‘0’, high-performance mode is valid for all ODRs (from 12.5 Hz up

to 6.66 kHz).

To enable the low-power and normal mode, the XL_HM_MODE bit has to be set to ‘1’. Low-

power mode is available for lower ODRs (12.5, 26, 52 Hz) while normal mode is available

for ODRs equal to 104 and 208 Hz.

Functionality LSM6DS3H

30/108 DocID028370 Rev 5

5.4 Interface flexibility with auxiliary SPI

In Mode3 configuration of the LSM6DS3H, interface flexibility is supported as follows:

Primary interface: I2C or SPI (3/4-wire)

Auxiliary interface: SPI (3-wire)

This configuration can support OIS applications, see details in the following figure.

Figure 5. Mode 3 interface configuration (OIS applications)

The primary interface is always available and the gyroscope output values are in registers

22h to 27h as per user-selected FS and ODR.

The auxiliary interface needs to be enabled in CTRL_SPIAux (70h) register and gyroscope

output values are in registers 22h to 27h with FS = 250 dps and ODR = 3.3 kHz. In this

interface SPI can write only to the dedicated register (CTRL_SPIAux (70h)). When the

auxiliary SPI is connected to the camera module, the recommendations are as follows:

Single axis enable bits in CTRL9_XL (18h) and CTRL10_C (19h) have to be ‘1’ (default

value)

Sign and orient bits in ORIENT_CFG_G (0Bh) have to be set to ‘0’ (default value)

Sleep bit in CTRL4_C (13h) has to be set to ‘0’ (default value)

Avoid using the self-test if the camera module is reading data

When the camera module is not connected, the device has the same behavior as the

LSM6DS3 (all bits supported).

LSM6DS3H Functionality
108
5.5 FIFO
The presence of a FIFO allows consistent power saving for the system since the host 
processor does not need continuously poll data from the sensor, but it can wake up only 
when needed and burst the significant data out from the FIFO.
LSM6DS3H embeds 4 kbyte FIFO + flexible 4 kbyte (FIFO or programmable) to store the 
following data:
gyroscope
accelerometer
external sensors
step counter and timestamp
temperature
Writing data in the FIFO can be configured to be triggered by the:
- accelerometer/gyroscope data-ready signal; in which case the ODR must be lower than or 
equal to both the accelerometer and gyroscope ODRs;
- sensor hub data-ready signal; 
- step detection signal.
In addition, each data can be stored at a decimated data rate compared to FIFO ODR and it 
is configurable by the user, setting the registers FIFO_CTRL3 (08h) and FIFO_CTRL4 
(09h). The available decimation factors are 2, 3, 4, 8, 16, 32.
Programmable FIFO threshold can be set in FIFO_CTRL1 (06h) and FIFO_CTRL2 (07h) 
using the FTH [11:0] bits.
To monitor the FIFO status, dedicated registers (FIFO_STATUS1 (3Ah), FIFO_STATUS2 
(3Bh), FIFO_STATUS3 (3Ch), FIFO_STATUS4 (3Dh)) can be read to detect FIFO overrun 
events, FIFO full status, FIFO empty status, FIFO threshold status and the number of 
unread samples stored in the FIFO. To generate dedicated interrupts on the INT1 and INT2 
pads of these status events, the configuration can be set in INT1_CTRL (0Dh) and 
INT2_CTRL (0Eh).
FIFO buffer can be configured according to five different modes:
– Bypass mode
– FIFO mode
– Continuous mode
– Continuous-to-FIFO mode
– Bypass-to-continuous mode
Each mode is selected by the FIFO_MODE_[2:0] in FIFO_CTRL5 (0Ah) register. To 
guarantee the correct acquisition of data during the switching into and out of FIFO mode, 
the first sample acquired must be discarded.

Functionality LSM6DS3H
32/108 DocID028370 Rev 5
5.5.1 Bypass mode
In Bypass mode (FIFO_CTRL5 (0Ah) (FIFO_MODE_[2:0] = 000), the FIFO is not 
operational and it remains empty.
Bypass mode is also used to reset the FIFO when in FIFO mode.
5.5.2 FIFO mode
In FIFO mode (FIFO_CTRL5 (0Ah) (FIFO_MODE_[2:0] = 001) data from the output 
channels are stored in the FIFO until it is full.
To reset FIFO content, Bypass mode should be selected by writing FIFO_CTRL5 (0Ah) 
(FIFO_MODE_[2:0]) to '000' After this reset command, it is possible to restart FIFO mode by 
writing FIFO_CTRL5 (0Ah) (FIFO_MODE_[2:0]) to '001'.
FIFO buffer memorizes up to 4096 samples of 16 bits each but the depth of the FIFO can be 
resized by setting the FTH [11:0] bits in FIFO_CTRL1 (06h) and FIFO_CTRL2 (07h). If the 
STOP_ON_FTH bit in CTRL4_C (13h) is set to '1', FIFO depth is limited up to FTH [11:0] 
bits in FIFO_CTRL1 (06h) and FIFO_CTRL2 (07h).
5.5.3 Continuous mode 
Continuous mode (FIFO_CTRL5 (0Ah) (FIFO_MODE_[2:0] = 110) provides a continuous 
FIFO update: as new data arrives, the older data is discarded.
A FIFO threshold flag FIFO_STATUS2 (3Bh)(FTH) is asserted when the number of unread 
samples in FIFO is greater than or equal to FIFO_CTRL1 (06h) and FIFO_CTRL2 
(07h)(FTH [11:0]).
It is possible to route FIFO_STATUS2 (3Bh) (FTH) to the INT1 pin by writing in register 
INT1_CTRL (0Dh) (INT1_FTH) = ‘1’ or to the INT2 pin by writing in register INT2_CTRL 
(0Eh) (INT2_FTH) = ‘1’.
A full-flag interrupt can be enabled, INT1_CTRL (0Dh) (INT_ FULL_FLAG) = '1', in order to 
indicate FIFO saturation and eventually read its content all at once. 
If an overrun occurs, at least one of the oldest samples in FIFO has been overwritten and 
the OVER_RUN flag in FIFO_STATUS2 (3Bh) is asserted.
In order to empty the FIFO before it is full, it is also possible to pull from FIFO the number of 
unread samples available in FIFO_STATUS1 (3Ah) and FIFO_STATUS2 (3Bh) 
(DIFF_FIFO[11:0]).
5.5.4 Continuous-to-FIFO mode
In Continuous-to-FIFO mode (FIFO_CTRL5 (0Ah) (FIFO_MODE_[2:0] = 011), FIFO 
behavior changes according to the trigger event detected in one of the following interrupt 
registers FUNC_SRC (53h), TAP_SRC (1Ch), WAKE_UP_SRC (1Bh) and D6D_SRC 
(1Dh). 
When the selected trigger bit is equal to '1', FIFO operates in FIFO mode. 
When the selected trigger bit is equal to '0', FIFO operates in Continuous mode. 

DocID028370 Rev 5 33/108
LSM6DS3H Functionality
108
5.5.5 Bypass-to-Continuous mode 
In Bypass-to-Continuous mode (FIFO_CTRL5 (0Ah) (FIFO_MODE_[2:0] = '100'), data 
measurement storage inside FIFO operates in Continuous mode when selected triggers in 
one of the following interrupt registers FUNC_SRC (53h), TAP_SRC (1Ch), 
WAKE_UP_SRC (1Bh) and D6D_SRC (1Dh) are equal to '1', otherwise FIFO content is 
reset (Bypass mode).
5.5.6  FIFO reading procedure
The data stored in FIFO are accessible from dedicated registers (FIFO_DATA_OUT_L 
(3Eh) and FIFO_DATA_OUT_H (3Fh)) and each FIFO sample is composed of 16 bits.
All FIFO status registers (FIFO_STATUS1 (3Ah), FIFO_STATUS2 (3Bh), FIFO_STATUS3 
(3Ch), FIFO_STATUS4 (3Dh)) can be read at the start of a reading operation, minimizing 
the intervention of the application processor.
Saving data in the FIFO buffer is organized in four FIFO data sets consisting of 6 bytes 
each:
The 1st FIFO data set is reserved for gyroscope data;
The 2nd FIFO data set is reserved for accelerometer data;
The 3rd FIFO data set is reserved for the external sensor data stored in the registers from 
SENSORHUB1_REG (2Eh) to SENSORHUB6_REG (33h);
The 4th FIFO data set can be alternately associated to the external sensor data stored in the 
registers from SENSORHUB7_REG (34h) to SENSORHUB12_REG(39h), to the step 
counter and timestamp info, or to the temperature sensor data.

LSM6DS3H Digital interfaces

108

6 Digital interfaces

The registers embedded inside the LSM6DS3H may be accessed through both the I2C and

SPI serial interfaces. The latter may be SW configured to operate either in 3-wire or 4-wire

interface mode. The device is compatible with SPI modes 0 and 3.

The serial interfaces are mapped onto the same pins. To select/exploit the I2C interface, the

CS line must be tied high (i.e connected to Vdd_IO).

6.1 I2C serial interface

The LSM6DS3H I2C is a bus slave. The I2C is employed to write the data to the registers,

whose content can also be read back.

The relevant I2C terminology is provided in the table below.

There are two signals associated with the I2C bus: the serial clock line (SCL) and the Serial

DAta line (SDA). The latter is a bidirectional line used for sending and receiving the data

to/from the interface. Both the lines must be connected to Vdd_IO through external pull-up

resistors. When the bus is free, both the lines are high.

The I2C interface is implemeted with fast mode (400 kHz) I2C standards as well as with the

standard mode.

In order to disable the I2C block, (I2C_disable) = 1 must be written in CTRL4_C (13h).

Slave The device addressed by the master

Digital interfaces LSM6DS3H

36/108 DocID028370 Rev 5

6.1.1 I2C operation

The transaction on the bus is started through a START (ST) signal. A START condition is

defined as a HIGH to LOW transition on the data line while the SCL line is held HIGH. After

this has been transmitted by the master, the bus is considered busy. The next byte of data

transmitted after the start condition contains the address of the slave in the first 7 bits and

the eighth bit tells whether the master is receiving data from the slave or transmitting data to

the slave. When an address is sent, each device in the system compares the first seven bits

after a start condition with its address. If they match, the device considers itself addressed

by the master.

The Slave ADdress (SAD) associated to the LSM6DS3H is 110101xb. The SDO/SA0 pin

can be used to modify the less significant bit of the device address. If the SDO/SA0 pin is

connected to the supply voltage, LSb is ‘1’ (address 1101011b); else if the SDO/SA0 pin is

connected to ground, the LSb value is ‘0’ (address 1101010b). This solution permits to

connect and address two different inertial modules to the same I2C bus.

Data transfer with acknowledge is mandatory. The transmitter must release the SDA line

during the acknowledge pulse. The receiver must then pull the data line LOW so that it

remains stable low during the HIGH period of the acknowledge clock pulse. A receiver

which has been addressed is obliged to generate an acknowledge after each byte of data

received.

The I2C embedded inside the LSM6DS3H behaves like a slave device and the following

protocol must be adhered to. After the start condition (ST) a slave address is sent, once a

slave acknowledge (SAK) has been returned, an 8-bit sub-address (SUB) is transmitted.

The increment of the address is configured by the CTRL3_C (12h) (IF_INC).

The slave address is completed with a Read/Write bit. If the bit is ‘1’ (Read), a repeated

START (SR) condition must be issued after the two sub-address bytes; if the bit is ‘0’ (Write)

the master will transmit to the slave with direction unchanged. Table 11 explains how the

SAD+Read/Write bit pattern is composed, listing all the possible configurations.

Data are transmitted in byte format (DATA). Each data transfer contains 8 bits. The number

of bytes transferred per transfer is unlimited. Data is transferred with the Most Significant bit

(MSb) first. If a receiver can’t receive another complete byte of data until it has performed

some other function, it can hold the clock line, SCL LOW to force the transmitter into a wait

state. Data transfer only continues when the receiver is ready for another byte and releases

the data line. If a slave receiver doesn’t acknowledge the slave address (i.e. it is not able to

receive because it is performing some real-time function) the data line must be left HIGH by

the slave. The master can then abort the transfer. A LOW to HIGH transition on the SDA line

while the SCL line is HIGH is defined as a STOP condition. Each data transfer must be

terminated by the generation of a STOP (SP) condition.

In the presented communication format MAK is Master acknowledge and NMAK is No

Master Acknowledge.

6.2 SPI bus interface

The LSM6DS3H SPI is a bus slave. The SPI allows writing and reading the registers of the

device.

The serial interface communicates to the application using 4 wires: CS, SPC, SDI and SDO.

Figure 9. Read and write protocol (in mode 3)

CS is the serial port enable and it is controlled by the SPI master. It goes low at the start of

the transmission and goes back high at the end. SPC is the serial port clock and it is

controlled by the SPI master. It is stopped high when CS is high (no transmission). SDI and

SDO are, respectively, the serial port data input and output. Those lines are driven at the

falling edge of SPC and should be captured at the rising edge of SPC.

Both the read register and write register commands are completed in 16 clock pulses or in

multiples of 8 in case of multiple read/write bytes. Bit duration is the time between two falling

edges of SPC. The first bit (bit 0) starts at the first falling edge of SPC after the falling edge

of CS while the last bit (bit 15, bit 23, ...) starts at the last falling edge of SPC just before the

rising edge of CS.

bit 0: RW bit. When 0, the data DI(7:0) is written into the device. When 1, the data DO(7:0)

from the device is read. In latter case, the chip will drive SDO at the start of bit 8.

bit 1-7: address AD(6:0). This is the address field of the indexed register.

bit 8-15: data DI(7:0) (write mode). This is the data that is written into the device (MSb first).

bit 8-15: data DO(7:0) (read mode). This is the data that is read from the device (MSb first).

In multiple read/write commands further blocks of 8 clock periods will be added. When the

CTRL3_C (12h) (IF_INC) bit is ‘0’, the address used to read/write data remains the same for

every block. When the CTRL3_C (12h) (IF_INC) bit is ‘1’, the address used to read/write

data is increased at every block.

The function and the behavior of SDI and SDO remain unchanged.

Quiet time is the time after the first detected tap in which there must not be any

overthreshold event. The default value of these bits is 00b which corresponds to

2*ODR_XL time. If the QUIET[1:0] bits are set to a different value, 1LSB

corresponds to 4*ODR_XL time.

SHOCK[1:0]
