The low power Intel486 SL microprocessor
S.C. Ellis · 2002
The author describes the Intel486 SL microprocessor and how the features are used to create robust, power managed portable computers. System performance was raised to the 25- and 33-MHz Intel486 DX microprocessor level. The system power consumption was significantly reduced with 3.3-V operation and power management refinements. The core system logic is reduced to at least half that of Intel386 SL microprocessor based systems. The system footprint was reduced from previous systems by the integration of the cache RAM and numeric coprocessor. The power management architecture is compatible with the Intel386 SL microprocessor, providing system vendors an easy upgrade for their systems and achieving a significant power reduction and performance increase.>
