1 Introduction
The SMG130 is a triaxial gyroscope for non-safety related applications, e.g. for in-dash naviga-
tion in the passenger compartment. Within one package, the SMG130 offers the detection of an-
gular rate in three perpendicular axes. The digital standard serial peripheral interface (SPI) of the
SMG130 allows for bidirectional data transmission.

Bosch wishes to point out that the system/product was not developed according to ISO 26262
standards, and has therefore been approved by Bosch only for applications that are not safety-
related.
2 Technical Description
2.1 Working Principle of the Sensing Element (MEMS)
The gyroscope SMG130 consists of an evaluation circuitry (ASIC) stacked on top of a micro-
mechanical sensing element (MEMS) within a standard LGA package.

2.6.2 Temperature Sensor
The temperature sensor data of the SMG130 are given in two’s complement representation with
a data width of 8 bits. Temperature data can be read from register 0x08 (TEMP). The slope is
typically 0.5 K/LSB.
