STEVAL-MKI001V1
Description
The STEVAL-MKI001V1 is an evaluation kit
designed to provide the user with a platform for
evaluating the LIS3L02AS4 MEMS accelerometer
in the SO24 package with analog output. It
implements a typical application composed of the
LIS3L02AS4 accelerometer and the TS924 rail-to-
rail precision buffer. The supply voltage is
generated by an LE33 voltage regulator, which
ensures the correct power required by the
LIS3L02AS4 device.
All parts on the STEVAL-MKI001V1 evaluation kit
board are STMicroelectronics components.

General circuit description
STEVAL-MKI001V1

General circuit description
The sensing element, capable of detecting the acceleration, is manufactured using a
dedicated process developed by ST to produce inertial sensors and actuators in silicon.
The IC interface is manufactured using a standard CMOS process that allows high level of
integration to design a dedicated circuit which is trimmed to better match the sensing
element characteristics.
The LIS3L02AS4 has a user selectable full scale of ±2g, ±6g and it is capable of measuring
accelerations over a bandwidth of 1.5 KHz for all axes. The device bandwidth may be
reduced by using external capacitances. A self-test capability allows to check the
mechanical and electrical signal path of the sensor.
The LIS3L02AS4 is available in plastic SMD package and it is specified over an extended
temperature range of -40°C to +85°C.
