The core of the Sam Flex board is the PowerPC 440EP, a System On Chip
(SoC) produced by AMCC under license from IBM. One of the main
features of the PowerPC AMCC 440EP is the presence, together with
the CPU, of a number of integrated peripherals. This allowed
to build a complete system with huge savings of both development
and debug time, with less components and space used on the PCB.
This also results in a significant cost reduction for the customer.
As a consequence the usual northbridge/southbridge combination is
not present on the Sam Flex board since parts of their functionalities are
already built into the CPU.
The 440EP chip has a size of 35x35 mm, with a PBGA packaging (456
balls). It is built with CMOS (0.13 um) technology, has a very
low power consumption (only 3 Watts at 533 MHz) and it does not
require any active cooling system.
