'''i486SL-25''' was a fourth-generation [[x86]] [[microprocessor]] introduced by [[Intel]] in 1992. This chip, which is based on the {{intel|microarchitectures/80486|80486 microarchitecture}}, operated at 25 MHz. Like the original i486DX, this chip implemented the {{intel|80387}} [[FPU]] on-die and incorporated {{intel|System Management Mode}} (SMM). This series was designed to be a low power version of the i486DX, offering lower voltage and power saving features for portable mobile computers.
