Core™-4xxx Processor
Microprocessor
The PC4-PRESTO is equipped with an Intel
®
Core
TM
i7, i5 or i3 4
th
generation mobile ECC processor
(code name “Haswell”). These low power processors provide integrated graphics, memory controller
and voltage regulators, which results in a very efficient platform design.
The Core
TM
i7/i5/i3 processor family includes units with several thermal design power (TDP) classes to
fit the customers requirements: 47W, 37W and 25W. The processors are housed in a Micro FC-BGA
package for direct soldering to the PCB, i.e. the chip cannot be removed or changed by the user.
The processors supported by the PC4-PRESTO are running at core clock speeds up to 2.4GHz for quad
core and up to 2.7GHz on dual core devices. Due to Enhanced Intel
®
SpeedStep
®
and Intel
®
Turbo
Boost Technology each core can decrease or increase its nominal operating frequency. The clock speed
is chosen depending on the power states of the processor cores/graphics engine, the currently
required performance, and the actual core temperature.
Power is applied across the CompactPCI
®
connector J1 (3.3V, 5V). The processors core voltage is
generated by a switched voltage regulator sourced from the 5V plane.
