The only difference between the various device configurations is the firmware content that is loaded into the flash memory at the

factory. The user still can add custom software using the remaining portion of flash memory.

The MMA9550, MMA95501, and MMA95503 devices can function immediately as they are. They have an internal command

interpreter and applications scheduler and can interact directly with the users’ host system.

The MMA9559 device provides the most flexibility and is for users who need to design their own control loop and system. The

device needs to be programmed with custom user code.
