Microcontroller for LIS3DH

Question asked by rajani.vishal on Mar 12, 2014
Couple of questions ...
1.  I have typically seen LIS3DH paired with Cortex M3 for e.g. in most of the health/fitness monitors. Is M3 required or could we use a M0/M0+. In other words what is the uC bandwidth required for ensuring no samples are dropped.
As per my calculation M0 should be sufficient and M3 has been used in those products to support DISPLAY and/or USB. Could some one confirm ? 

2. Further on does LIS3DH require a dedicated microcontroller or can it be shared with a uC (MSP430/8051/Cortex M0) which is part of say the Bluetooth connectivity SoC ?
