Template:mpu Am486SE-25 was an 80486-compatible microprocessor introduced by AMD. This processor operated at 25 MHz and as with the rest of the SX-line, did not have a functional FPU on-die. This model is identical to the Am486SX except for the fact that it was geared toward the embedded market from a company-support standpoint.
