The Intel SL Technology, features in the Intel486 processors, allow system designers to build intelligent power management capabilities into hardware, making these capabilities independent of application software. Power management becomes an integral part of the system, regardless of what operating system or application is used. Power management is improved because SL Technology protects the power management features from conflicting with other software.

Ultra Low Power Intel486™ SX and Intel486 GX Embedded Processor Family
The Ultra Low Power Intel486 SX embedded processor is the first member of a family of Intel486 processors to be developed specifically for the embedded market. It brings high levels of performance to low-cost, entry-level, embedded applications, where maximum energy efficiency is a high concern. These low-power technology improvements allow for new packaging options for the Intel486 processor. The Ultra Low Power Intel486 SX processor comes in the 176 lead Thin Quad Flat Pack(TQFP) package. This is the smallest, lowest profile Intel486 processor in the world. At 25.4mm x 25.4mm x 1.5mm, the 176 lead TQFP package is the same size and thickness as the United States quarter (25 cent coin)! The Ultra Low Power Intel486 GX is also available as an Intel SmartDie® product, which is ideal for the most compact designs.

IntelDX2™ and IntelDX4™ Processor Family
The IntelDX2 and IntelDX4 processors bring the highest level of performance in the Intel486™ family, created by such combined features as speed-multiplying technology, on-chip integration of Level I unified code and data cache, memory management unit with paging, and floating-point unit. The clock-multiplier allows the processor to operate at frequencies higher than the external memory bus. The integer unit uses RISC design techniques to provide single-clock-cycle execution of common instructions and general purpose registers for manipulating 32-bit addresses and data. The 8K on-chip Write-Through unified cache on the speed-doubled IntelDX2 processor, and the 16K on-chip Write-Back Enhanced unified cache on the speed-tripled IntelDX4 processor maintains the one-clock-per-instruction execution rate. Intel 486 processors provide support for multiprocessing systems. Support for multi-level caches reduces bus utilization, allowing multiple Intel486 processors to share a single memory bus. For the highest level of performance, choose the IntelDX2 and IntelDX4 processors.
