advertisement Dual Regulators Power Pentium Processor or Upgrade CPU
Design Note 122
Craig Varga
Many manufacturers of Pentium processor-based
motherboards have been searching for an economical
solution to the problem of powering the present generation Pentium P54C and accommodating the upgrade
processors that will soon become available. The existing
processor uses a single supply for both the processor
core and the I/O. For the highest frequency offerings,
the supply required is 3.5V В±100mV (VRE speciп¬Ѓcation).
For the lower performance end of the clock frequency
spectrum, a supply voltage of 3.3V В±5% is adequate.
Recently, Intel respeciп¬Ѓed the standard 3.3V CPUs for
operation at 3.5V. This allows designs for any clock
frequency to be operated from a single 3.5V supply. The
I/O ring and chipset should be powered by the same
voltage as the CPU core, whether that is 3.3V or 3.5V.
The P55C upgrade processor, which will soon be available, requires separate supplies for the core and the I/O.
The nominal core voltage is targeted at 2.500V В±5%,
whereas the I/O supply is still nominally 3.3V. There is
also a processor pin, VCC2DET, at location AL1, that is
bonded to ground on the P55C, but is open on the P54C.
A signiп¬Ѓcant complication is introduced by the core …
