Function Blocks
Processor
The CM Board is equipped with an Atmel ARM-based embedded MPU, as listed below, in a 217-ball
BGA package. The five devices share an identical footprint. All five share the same CM Board PCB with
minor configuration differences.
The five devices are:
SAM9G15
SAM9G25
SAM9G35
SAM9X25
SAM9X35
As different interfaces can be defined using the same pins, it depends on the actual configuration of the
CPU as to which functions are in fact available to the EK board.
Refer to Section 4.2.4.1 ”Chip Identification” for details. The processor runs at a nominal frequency of
400 MHz for the core and 133 MHz for the system bus.
The peripheral configuration possibilities and implementation requirements of the CM are dependent on
the module's chipset. Two configuration resistors are implemented on board in order to select the mode
of configuration.
Clock Circuitry
The CM includes 3 clock sources:
Two are alternatives for the processor main clock
One crystal and one crystal oscillator are used for the Ethernet MII/RMII chip
