Hi I took a activity tracker apart with the goal of writing my own 
firmware for it. I stumbled accross the component in the picture. But 
don't know at all what  it could be. It is directly wired to an 
accelerometer and a 256Kbit EEPROM.
Do you recognize the Logo?

Background information:
The activity tracker is based on the nRF51822
Link to the complete circuit board with background information:

Thank you very much, that looks very promising. How did you find that 
out?
