Extended HALT Maximum Power Symbol Parameter Min PEXTENDED_HALT Quad-Core Intel® Xeon® Processor X5482 Extended HALT State Power PEXTENDED_HALT Quad-Core Intel® Xeon® Processor X5400 Series PEXTENDED_HALT Quad-Core Intel® Xeon® Processor E5400 Series PEXTENDED_HALT Quad-Core Intel® Xeon® Processor L5400 Series PEXTENDED_HALT Quad-Core Intel® Xeon® Processor L5408 Extended HALT State Power Extended HALT State Power Extended HALT State Power Extended HALT State Power Typ Max 16 Unit W Notes 1 2 16 W 2 16/20 W 2,3 12 W 2 12 W 4 Notes: 1. Processors running in the lowest bus ratio supported as shown in Table 2-1, will enter the HALT State when the processor has executed the HALT or MWAIT instruction since the processor is already operating in the lowest core frequency and voltage operating point. 2. The specification is at Tcase = 40oC and nominal Vcc. The VID setting represents the maximum expected VID when running in HALT state. 3. SKUs with Extended HALT state (16W) and without Extended HALT state (20W). 4. The specification is at Tcase = 46oC and nominal Vcc. The VID setting represents the maximum expected VID when running in HALT state. The processor exits the Extended HALT state when a break event occurs. When the processor exits the Extended HALT state, it will first transition the VID to the original value and then change the bus to core frequency ratio back to the original value. 99
