Description
The LSM330DL is a system-in-package featuring
a 3D digital accelerometer and a 3D digital
gyroscope.
ST’s family of modules leverages a robust and
mature manufacturing process already used for
the production of micromachined accelerometers.
The various sensing elements are manufactured
using specialized micromachining processes,
while the IC interfaces are based on CMOS
technology that allows designing a dedicated
circuit which is trimmed to better match the
sensing element characteristics.
The LSM330DL has a dynamic, user-selectable
full-scale acceleration range of ±2g/±4g/±8g/±16g
and an angular rate of ±250/±500/±2000 deg/sec.
The accelerometer and gyroscope sensors can
be either activated or put in low-power / power-
down mode separately for power-saving
optimized applications. The LSM330DL is
available in a plastic land grid array (LGA)
package.
Several years ago ST successfully pioneered the
use of this package for accelerometers. Today, ST
has the broadest manufacturing capability in the
world and unrivalled expertise for the production
of sensors in a plastic LGA package.

2.6 Terminology
2.6.1 Sensitivity
Linear acceleration sensitivity can be determined by applying 1 g acceleration to the device.
As the sensor can measure DC accelerations, this can be done easily by pointing the axis of
interest towards the center of the Earth, noting the output value, rotating the sensor by 180
degrees (point to the sky) and then 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 also very little over time. The sensitivity tolerance
describes the range of sensitivities of a large population 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.
2.6.2 Zero 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 the X-axis and 0 g on the Y-axis whereas the Z-axis
will measure 1 g. The output is ideally 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 the 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 “Zero-g level change vs. temperature” (refer toTable 3).
The zero-g level tolerance (TyOff) describes the standard deviation of the range of zero-g
levels of a population of sensors.
The 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 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 also very little over time.
Functionality LSM330DL
18/54 Doc ID 022018 Rev 1
3 Functionality
The LSM330DL is a system-in-package featuring a 3D digital accelerometer and a 3D digital
gyroscope.
The complete device includes specific sensing elements and two IC interfaces able to
measure both the acceleration and angular rate applied to the module and to provide a
signal to the external world through an SPI/I2C serial interface.
The various sensing elements are manufactured using specialized micromachining
processes, while the IC interfaces are based on CMOS technology that allows designing a
dedicated circuit which is trimmed to better match the sensing element characteristics.
The LSM330DL may also be configured to generate an inertial wake-up and free-fall
interrupt signal according to a programmed acceleration event along the enabled axes.
3.1 Factory calibration
The IC interface is factory calibrated for sensitivity and zero level. The trimming values are
stored inside the device in non-volatile memory. Any time the device is turned on, the
trimming parameters are downloaded into the registers to be used during normal operation.
This allows using the device without further calibration.

4.1 External capacitors
The device core is supplied through the Vdd line. Power supply decoupling capacitors
(C4=100 nF ceramic, C3=10 µF Al) should be placed as near as possible to the supply pin
of the device (common design practice).
All the voltage and ground supplies must be present at the same time to have proper
behavior of the IC (refer to Figure 5).
The functionality of the device and the measured acceleration/angular rate data is
selectable and accessible through the SPI/I2C interface.

LSM330DL Digital interfaces
Doc ID 022018 Rev 1 21/54
5 Digital interfaces
The registers embedded inside the LSM330DL 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).
5.1 I2C serial interface
The LSM330DL I2C is a bus slave. The I2C is employed to write data into the registers
whose content can also be read back.
The relevant I2C terminology is given 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 LSM330DL
22/54 Doc ID 022018 Rev 1
5.1.1 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 own 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 inside the LSM330DL 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) will be
transmitted: the 7 LSb represents the actual register address while the MSB enables the
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/writes.
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 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 presented communication format MAK is Master acknowledge and NMAK is No
Master Acknowledge.
Default address
The SDO/SA0 pad can be used to modify the least significant bit of the device address. If
the SA0 pad is connected to a voltage supply, LSb is ‘1’ (ex. address 0011001b), else 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 the direction unchanged. Table 16 and
Table 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

5.2 SPI bus interface
The LSM330DL SPI is a bus slave. The SPI allows to write and read the registers of the
device.
The Serial Interface interacts with the outside world with 4 wires: CS, SPC, SDI and SDO
(SPC, SDI, SD0 are common).
Figure 6. Read and write protocol
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. 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 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 the latter case, the chip will drive SDO at the start of bit 8.
bit 1: MS bit. When 0, the address will remain unchanged in multiple read/write commands.
When 1, the address will be 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 into 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.

The contents of the INT1_CFG_REG_A register are loaded at boot.
A write operation at this address is possible only after system boot.
The difference between AOI-6D = ‘01’ and AOI-6D = ‘11’ is defined as follows:
AOI-6D = ‘01’ is movement recognition. An interrupt is generated when the orientation
moves from an unknown zone to a known zone. The interrupt signal stays for a duration
determined by ODR.
AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation is
inside a known zone. The interrupt signal stays until orientation is inside the zone.

7.38 INT1_SRC_G (31h)
The interrupt source register is a 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 refreshment of data in the INT1_SRC_G register if the
latched option was chosen.

7.45 INT1_DURATION_G (38h)
The D6 - D0 bits set the minimum duration of the interrupt event to be recognized. The
duration of the steps and maximum values depend on the ODR chosen.
The WAIT bit has the following meaning:
Wait =’0’: the interrupt falls immediately if the 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.
