the interface i2c, ( slave) at 400khz ,, but also has a "pass Through Mode to get the sensor information directly , the 6 axis info is processed at 16bit resolution adc on each , with 3 compass adc at 13 bit resolution , has built in charge pump for gyros

the sensor info is presented at upto to 1024 bytes via the fifo in burst mode

the use of the int pin has mainly the status info modes

it allow s for a 3rd party pressure sensor off a 2nd i2c interface

3.3v device

it looks like you could use a 8 bit pic , but like all things depends on how fast you need to process the the data this thing is giving
