Description
The LSM330DLC is a system-in-package
featuring a 3D digital accelerometer and a 3D
digital gyroscope.
ST’s family of MEMS sensor modules leverages
the robust and mature manufacturing processes
already used for the production of micromachined
accelerometers.
The various sensing elements are manufactured
using specialized micromachining processes,
while the IC interfaces are developed using a
CMOS technology that allows the design of a
dedicated circuit which is trimmed to better match
the sensing element characteristics.
The LSM330DLC has dynamically user-
selectable full scale acceleration range of
±2 g/±4 g/±8 g/±16 g and angular rate of
±250/±500/±2000 deg/sec.
The accelerometer and gyroscope sensors can
be either activated or separately put in Low
power/Power-down mode for applications
optimized for power saving.
The LSM330DLC is available in a plastic land grid
array (LGA) package.

Terminology LSM330DLC
20/67 Doc ID 022162 Rev 1
3 Terminology
3.1 Sensitivity
Linear acceleration sensitivity can be determined e.g. 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.
Angular Rate Sensitivity describes the angular rate gain of the sensor and can be
determined by applying a defined angular velocity to it. This value changes very little over
temperature and also very little over time.
3.2 Zero-g 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 axes, 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 Ta b l e 3 . The zero-g level tolerance
(TyOff) describes the standard deviation of the range of zero-g levels of a group of sensors.
Angular rate zero-rate level describes the actual output value if there is no angular rate
present. zero-rate level of precise MEMS sensors is, to some extent, a result of stress to the
sensor and therefore 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 over time.
LSM330DLC Functionality
Doc ID 022162 Rev 1 21/67
4 Functionality
The LSM330DLC is a system-in-package featuring a 3D digital accelerometer and a 3D
digital gyroscope.
The device includes specific sensing elements and two IC interfaces capable to measuring
both the acceleration and angular rate applied to the module and to provide a signal to
external applications through an SPI/I2C serial interface.
The various sensing elements are manufactured using specialized micromachining
processes, while the IC interfaces are developed using a CMOS technology that allows the
design of a dedicated circuit which is trimmed to better match the sensing element
characteristics.
The LSM330DLC may also be configured to generate an inertial wakeup and free-fall
interrupt signal according to a programmed acceleration event along the enabled axes.
4.1 Normal mode, Low power mode
The LSM330DLC provides two different operating modes: Normal mode and Low power
mode. Normal mode guarantees high resolution, while Low power mode further reduces
current consumption.
The table below summarizes how to select the operating mode and the corresponding
characteristics.
4.1.1 Self-test
Self-test allows the checking of sensor functionality without moving it. The self-test function
is off when the self-test bit (ST) is programmed to ‘0’. When the self-test bit is programmed
to ‘1’ an actuation force is applied to the sensor, simulating a definite input acceleration. In
this case, the sensor outputs exhibit a change in their DC levels which are related to the
selected full scale through the device sensitivity. When self-test is activated, the device
output level is given by the algebraic sum of the signals produced by the acceleration acting
on the sensor and by the electrostatic test-force. If the output signals change within the
amplitude specified in Ta bl e 3 , then the sensor is working properly and the parameters of
the interface chip are within the defined specifications.
4.1.2 6D/4D orientation detection
The LSM330DLC includes 6D/4D orientation detection. In this configuration the interrupt is
generated when the device is stable in a known direction. In 4D configuration, Z axis
position detection is disabled.
Table 9. Operating mode selection

Normal mode (12-bit) 0 1 ODR/9 7/ODR(kHz)
Functionality LSM330DLC
22/67 Doc ID 022162 Rev 1
4.1.3 “Sleep-to-wake” and “Return to sleep”
The LSM330DLC can be programmed to automatically switch to Low power mode upon
recognition of a determined event. Once the event condition is over, the device returns to the
preset Normal mode.
To enable this function, the desired threshold value must be stored in the Act_THS register,
while the duration value is written in the Act_DUR register.
When the internally high-pass filtered acceleration becomes lower than the threshold value
on all the three axes, the device automatically switches to Low power mode (10Hz ODR).
During this condition, the ODRx bits and LPen bit in the CTRL_REG1_G register and the
HR bit in the CTRL_REG3_G register are not considered.
When the acceleration goes back over the threshold (on at least one axis), the system
restores the operating mode and ODRs as per the CTRL_REG1_G register and
CTRL_REG3_G register settings.
4.2 Linear acceleration digital main blocks
4.2.1 FIFO
The LSM330DLC embeds 32 slots of data FIFO for each of the three output channels: X, Y
and Z. This allows consistent power saving for the system, since the host processor does
not need to continuously poll data from the sensor, but it can wake up only when needed
and burst the significant data out from the FIFO. This buffer can work accordingly in four
different modes: Bypass mode, FIFO mode, Stream mode and Stream-to-FIFO mode. Each
mode is selected by the FIFO_MODE bits in the FIFO_CTRL_REG_A register.
Programmable watermark level, FIFO_empty or FIFO_Full events can be enabled to
generate dedicated interrupts on the INT1_A/INT2_A pin (configured through the
FIFO_CTRL_REG_A register).
4.2.2 Bypass mode
In Bypass mode, the FIFO is not operational and for this reason it remains empty. For each
channel only the first address is used. The remaining FIFO slots are empty.
4.2.3 FIFO mode
In FIFO mode, data from the X, Y and Z channels are stored into the FIFO. A watermark
interrupt can be enabled (FIFO_WTMK_EN bit in the FIFO_CTRL_REG_A register in order
to be raised when the FIFO is filled to the level specified into the FIFO_WTMK_LEVEL bits
of the FIFO_CTRL_REG_A register. The FIFO continues filling until it is full (32 slots of data
for X, Y and Z). When full, the FIFO stops collecting data from the input channels.
4.2.4 Stream mode
In Stream mode, data from X, Y and Z measurement are stored into the FIFO. A watermark
interrupt can be enabled and set as in FIFO mode.The FIFO continues filling until it is full (32
slots of data for X, Y and Z). When full, the FIFO discards the older data as the new data
arrives.
LSM330DLC Functionality
Doc ID 022162 Rev 1 23/67
4.2.5 Stream-to-FIFO mode
In Stream-to-FIFO mode, data from X, Y and Z measurement is stored in the FIFO. A
watermark interrupt can be enabled (FIFO_WTMK_EN bit in the FIFO_CTRL_REG_A
register) in order to be raised when the FIFO is filled to the level specified in the
FIFO_WTMK_LEVEL bits of the FIFO_CTRL_REG_A register. The FIFO continues filling
until it is full (32 slots of 8 -bit data for X, Y and Z). When full, the FIFO discards the older
data as the data new arrives. Once trigger event occurs, the FIFO starts operating in FIFO
mode.
4.2.6 Retrieve data from FIFO
FIFO data is read through OUT_X_L_A (28h), OUT_X_H_A (29h), OUT_Y_L_A (2Ah),
OUT_Y_H_A (2Bh) and OUT_Z_L _A (2Ch), OUT_Z_H_A (2Dh). When the FIFO is in
Stream, Trigger or FIFO mode, a read operation to the OUT_X_L_A (28h), OUT_X_H_A
(29h), OUT_Y_L_A (2Ah), OUT_Y_H_A (2Bh) or OUT_Z_L _A (2Ch), OUT_Z_H_A (2Dh)
registers provides the data stored in the FIFO. Each time data is read from the FIFO, the
oldest X, Y and Z data are placed in the OUT_X_L_A (28h), OUT_X_H_A (29h),
OUT_Y_L_A (2Ah), OUT_Y_H_A (2Bh) and OUT_Z_L _A (2Ch), OUT_Z_H_A (2Dh)
registers and both single read and read_burst operations can be used.

4.4 FIFO
The LSM330DLC embeds 32 slots of 16-bit data FIFO for each of the three output channels:
yaw, pitch and roll. This allows consistent power saving for the system, since the host
processor does not need to continuously poll data from the sensor, but can wake up only
when needed and burst the significant data out from the FIFO. This buffer can work
accordingly in five different modes: Bypass mode, FIFO mode, Stream mode, Bypass-to-
Stream mode and Stream-to-FIFO mode. Each mode is selected by the FIFO_MODE bits in
the FIFO_CTRL_REG_G register. Programmable watermark level, FIFO_empty or
FIFO_Full events can be enabled to generate dedicated interrupts on the DRDY_G/INT2_G
pin (configured through the CTRL_REG3_G register and event detection information is
available in the FIFO_SRC_REG_G register. Watermark level can be configured to WTM4:0
in the FIFO_CTRL_REG_G register.
4.4.1 Bypass mode
In Bypass mode, the FIFO is not operational and for this reason it remains empty. As
described in Figure 6 below, for each channel only the first address is used. The remaining
FIFO slots are empty. When new data is available the old data is overwritten.
Figure 6. Bypass mode
4.4.2 FIFO mode
In FIFO mode, data from the yaw, pitch and roll channels is stored in the FIFO. A watermark
interrupt can be enabled (I2_WMK bit in the CTRL_REG3_G register) in order to be raised
when the FIFO is filled to the level specified in the WTM 4:0 bits of the FIFO_CTRL_REG_G
register. The FIFO continues filling until it is full (32 slots of 16-bit data for yaw, pitch and
roll). When full, the FIFO stops collecting data from the input channels. To restart data
collection, the FIFO_CTRL_REG_G register must be written back to Bypass mode.
FIFO mode is represented in Figure 7: FIFO mode.

4.4.4 Bypass-to-stream mode
In Bypass-to-stream mode, the FIFO starts operating in Bypass mode and once a trigger
event occurs (related to INT1_CFG_G register events) the FIFO starts operating in Stream
mode. Refer to Figure 9 below.
Figure 9. Bypass-to-stream mode
4.4.5 Stream-to-FIFO mode
In Stream-to-FIFO mode, data from yaw, pitch and roll measurement is stored in the FIFO. A
watermark interrupt can be enabled on pin DRDY/INT2 by setting the I2_WTM bit in
CTRL_REG3_G register to be raised when the FIFO is filled to the level specified in the
WTM4:0 bits of the FIFO_CTRL_REG_G register. The FIFO continues filling until it is full
(32 slots of 16-bit data for yaw, pitch and roll). When full, the FIFO discards the older data as
the new data arrives. Once a trigger event occurs (related to INT1_CFG_G register events),
the FIFO starts operating in FIFO mode. Refer to Figure 10: Trigger stream mode.

4.6 Factory calibration
The IC interface is factory calibrated for sensitivity and zero level. The trimming values are
stored in the device in non volatile memory. Any time the device is turned on, the trimming
parameters are downloaded to the registers to be used during normal operation. This allows
use of the device without further calibration.

5.1 External capacitors
The device core is supplied through the Vdd line. Power supply decoupling capacitors (C2,
C3=100 nF ceramic, C4=10 µF Al) should be placed as near as possible to the supply pin of
the device (common design practice).
All voltage and ground supplies must be present at the same time to achieve proper
behavior of the IC (refer to Figure 13).
The functionality of the device and the measured acceleration/angular rate data is
selectable and accessible through the SPI/I2C interface.
The functions, the threshold and the timing of the two interrupt pins for each sensor can be
completely programmed by the user through the SPI/I2C interface.

6 Digital interfaces
The registers embedded in the LSM330DLC 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.
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 LSM330DLC 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.

Term Description
Transmitter The device which sends data to the bus
Receiver The device which receives data from the bus
Master The device which initiates a transfer, generates clock signals and terminates a
transfer
Slave The device addressed by the master
Digital interfaces LSM330DLC
34/67 Doc ID 022162 Rev 1
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.
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 in the LSM330DLC 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
7 LSb represent the actual register address while the MSb enables address auto increment.
If the MSb of the SUB field is ‘1’, the SUB (register address) will be automatically increased
to allow multiple data read/write.
Data is transmitted in byte format (DATA). Each data transfer contains 8 bits. The number of
bytes sent per transfer is unlimited. Data is transferred with the most significant bit (MSb)
first. If a receiver cannot 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.

LSM330DLC Digital interfaces
Doc ID 022162 Rev 1 35/67
Data transfer only continues when the receiver is ready for another byte and releases the
data line. If a slave receiver does not 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 order to read multiple bytes, it is necessary to assert the most significant bit of the sub-
address field. In other words, SUB(7) must be equal to 1 while SUB(6-0) represents the
address of first register to be read.
In the communication format presented, MAK is Master Acknowledge and NMAK is No
Master Acknowledge.
Default address:
The SDO/SA0 pin (SDO_A / SDO_G) can be used to modify the least significant bit of the
device address. If the SA0 pad is connected to voltage supply, the LSb is ‘1’ (ex. address
0011001b), otherwise if the SA0 pad is connected to ground, the LSb value is ‘0’ (ex
address 0011000b).
The slave address is completed with a Read/Write bit. If the bit was ‘1’ (Read), a repeated
START (SR) condition will have to be issued after the two sub-address bytes; if the bit is ‘0’
(Write) the master will transmit to the slave with direction unchanged. Tab l e 1 6 and 17
explain how the SAD+Read/Write bit pattern is composed, listing all the possible
configurations.
Linear acceleration address: the default (factory) 7-bit slave address is
001100xb.
Angular rate sensor: the default (factory) 7-bit slave address is 110101xb.

6.2 SPI bus interface
The LSM330DLC SPI is a bus slave. The SPI allows writing and reading the registers of the
device.
The serial interface interacts with the outside world through 4 wires: CS, SPC, SDI and SDO
(SPC, SDI, SD0 are common).
Figure 14. Read and write protocol
CS is the serial port enable and is controlled by the SPI master. It goes low at the start of the
transmission and returns high at the end. SPC is the serial port clock and 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. These 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-byte read/write. 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 to the device. When 1, the data DO(7:0)
from the device is read. In the latter case, the chip drives SDO at the start of bit 8.
bit 1: MS bit. When 0, the address remains unchanged in multiple read/write commands.
When 1, the address is auto-incremented in multiple read/write commands.
bit 2-7: address AD(5:0). This is the address field of the indexed register.
bit 8-15: data DI(7:0) (Write mode). This is the data that will be written to the device (MSb
first).
bit 8-15: data DO(7:0) (Read mode). This is the data that will be read from the device (MSb
first).
In multiple read/write commands, further blocks of 8 clock periods will be added. When the
MS bit is ‘0’, the address used to read/write data remains the same for every block. When
the MS 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.

WTM WTM bit is set high when FIFO content exceeds watermark level
OVRN_FIFO OVRN bit is set high when FIFO buffer is full, this means that the FIFO buffer
contains 32 unread samples. At the following ODR a new sample set replaces the
oldest FIFO value. The OVRN bit is reset when the first sample set has been read
EMPTY EMPTY flag is set high when all FIFO samples have been read and FIFO is empty
FSS4-0 FSS[4:0] field always contains the current number of unread samples stored in the
FIFO buffer. When FIFO is enabled, this value increases at ODR frequency until
the buffer is full, whereas, it decreases every time that one sample set is retrieved
from FIFO

The difference between AOI-6D = ‘01’ and AOI-6D = ‘11’.
AOI-6D = ‘01’ is movement recognition. An interrupt is generated when the orientation
moves from “unknown zone” to “known zone”. The interrupt signal remains for an ODR
duration.
AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation is
inside a “known zone”. The interrupt signal remains until orientation is within the zone.

Interrupt source register. Read only register.
Reading at this address clears the INT1_SRC_G IA bit (and eventually the interrupt signal
on the INT1_G pin) and allows the refreshing of data in the INT1_SRC_G register if the
latched option was chosen.

WAIT bit has the following meaning:
Wait =’0’: the interrupt falls immediately if signal crosses the selected threshold
Wait =’1’: if the signal crosses the selected threshold, the interrupt falls only after the
duration has counted the number of samples at the selected data rate, written into the
duration counter register.
