2.4Processor 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.

2.4.1Processor 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.
