i486SL-25 - Intel
Template:mpu i486SL-25 was a fourth-generation x86 microprocessor introduced by Intel in 1992. This chip, which is based on the 80486 microarchitecture, operated at 25 MHz. Like the original i486DX, this chip implemented the 80387 FPU on-die and incorporated 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.
