LSM330DL

Linear sensor module

Preliminary data

LLGA 28L 7.5 x 4.4 x 1.1 mm

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 / powerdown 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.

Description

The LSM330DL is a system-in-package featuring a 3D digital accelerometer and a 3D digital gyroscope.

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

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/I

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.

C serial interface.

Doc ID 022018 Rev 1 21/54

Digital interfaces LSM330DL

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 I

C 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.

Slave SAK SAK SAK DATA DATA DATA

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

LSM330DL Digital interfaces

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 subaddress 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.

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

SPC

SDI

AD5 AD4 AD3 AD2 AD1 AD0

SDO

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.

DI7DI6DI5DI4DI3DI2DI1DI0

DO7DO6DO5DO4DO3DO2DO1DO0

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 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.

WAIT WAIT enable. Default value: 0 (0: disable; 1: enable)

D6 - D0 Duration value. Default value: 000 0000

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.
