LSM6DS33

iNEMO inertial module:

always-on 3D accelerometer and 3D gyroscope

Datasheet

production data

Description

The LSM6DS33 is a system-in-package featuring a 3D

digital accelerometer and a 3D digital gyroscope

performing at 1.25 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 LSM6DS33 supports main OS requirements,

offering real, virtual and batch sensors with 8 kbyte for

dynamic data batching.

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 LSM6DS33 has a full-scale acceleration range of

±2/±4/±8/±16

and an angular rate range of

±125/±245/±500/±1000/±2000 dps.

High robustness to mechanical shock makes the

LSM6DS33 the preferred choice of system designers

for the creation and manufacturing of reliable products.

The LSM6DS33 is available in a plastic land grid array

(LGA) package.

LGA-16L (3 x 3 x 0.86 mm) typ.
