2.4 Processor Support
The reference board supports the Intel® Atom™ processor Z530 with 512-KB cache in
a 441-pin, FCBGA package. No heatsink is required by this processor during room
temperature ambient operation.
2.4.1 Processor Voltage Regulators
The reference board uses an onboard Intel® MVP6 single-phase regulator for the
processor core supply. The I/O voltage is 1.05 V. See
Section 4.5 for VID jumper
location and Appendix B for the VID code table.
