FXLC95000CL Datasheet, PDF (17/38 Pages) Freescale Semiconductor, Inc – Xtrinsic FXLC95000CL Intelligent, Motion-Sensing Platform

General Description
Intelligent Sensing Platform can interface and manage almost any type of sensor,
digital or analog, such as pressure sensors, magnetometers, gyroscopes, and humidity
sensors. The system supports external sensors interfacing to FXLC95000CL
concurrently, via a combination of master SPI and master I²C interfaces, and external
differential analog inputs.
Besides FXLC95000CL rich connectivity, the 32-bit core and hardware Multiply
Accumulator (MAC) provide the processing power to collect, manipulate and fuse all
sensors measurement locally and make appropriate decisions to optimize overall
system power consumption.
For example, FXLC95000CL can be programmed to operate effectively as a power
controller for handheld units by enabling the host platform to put itself to sleep, with
confidence that the FXLC95000CL will issue a wake-up request when an external
event requires the host's attention. Figure 5 shows the FXLC95000CL being used in
this sensor hub configuration. Note the simple connections. Only a few bypass
capacitors, a ferrite bead, and pullup resistors for the I²C buses are required.
• Slave I²C interface is dedicated to communication with the host processor.
Interrupt output line INT_O can be involved as well.
• Master SPI, Master I²C, AN0/AN1 and interrupt input line INT_I are available to
interface a variety of external sensors
