1.4 Overview
The FSP201 is a 6-axis IMU processor, integrating CEVA's high-
performance sensor hub software stack, to provide heading and orientation
outputs. When connected to one of several supported sensors, it performs all
the accelerometer and gyroscope sensor fusion processing necessary to
produce stable and accurate heading and orientation outputs. This document
is intended to provide information about the FSP201 Module to facilitate
customer evaluation.

2. Hardware
2.1 Introduction
The FSP201 Module includes the FSP201 sensor hub processor with either
the Bosch BMI088 or ST Micro LSM6DSR 6-axis sensor.
Figure 2-1: FSP201 Module with BMI088
2.2 Connections
The FSP201 communicates with the host system over a UART or I2C
interface. The UART interface can be either in UART-RVC mode or in
UART-SHTP mode. The I2C interface is in I2C over SHTP mode.
In UART-SHTP or I2C-SHTP modes, the FSP201 uses the Sensor Hub
Transport Protocol (SHTP) to communicate with a system or application
processor. The SHTP protocol is documented in the Sensor Hub Transport
Protocol [4], allowing a customer to potentially develop their own host
software if they choose to do so.
In UART-RVC mode, the FSP201 transmits heading and sensor information
at 100Hz.
The host protocol selection is made with the PS0 and PS1 signals. The
module’s default configuration is UART-RVC mode.

2.2.1 Host Interface Mode Selection
The module can be configured for any of the following host interface options.
The PS pins are set for UART-RVC mode by default. To select a different
interface mode just terminate the PS per the table below. For example, to
select I2C-SHTP mode you will need to pull PS0 pin low. Interface selection
is done at startup time, please see the FSP201 Datasheet (1) for more
information.
