functional hex file bigger than flash size limit?

I'm developing with nRF51 DK(development kit) which has nRF51822 chip connected to an interface MCU (ATSAM3U2CA).

Checking out the datasheet for nRF51822, it says the flash size is 256 or 128kB.

However, a functional hex file that I put into it which was compiled and downloaded from the online mbed compiler, has a size of 350kB.

How can this be?

Is the hex file also including some code that is processed by the interface MCU??
