SME5224AUPA-360
360 MHz CPU, 4.0 MB E-Cache
UltraSPARC-II CPU Module
July 1999
Sun Microsystems, Inc
Module Power Consumption
This UltraSPARC-II CPU module requires two supply voltages. The required voltages (provided to the mod-
ule) for the V
DD and VDD_CORE, are respectively 3.3V and 2.6V. The estimated maximum power consumption of
the UltraSPARC–II, 360 MHz CPU, 4.0 Mbyte E-cache module (SME5224AUPA-360) is 64 watts at 360 MHz.
The estimated maximum power consumption includes the CPU, the SRAMs, the clock logic and the 8 watts
consumed by the DC-DC regulator.

2. The supply current for the
V
DD includes the supply current for the CPU, UDB-II, and the SRAMs.
3. The typical DC current values represent the current drawn at nominal voltage with a typical, busy computing load. Variations in the
device, computing load, and system implementation affect the actual current. The maximum DC current values will rarely, if ever, be
exceeded running all known computing loads over the entire operating range. The maximum values are based on simulations.
