'''Am486DE2-66V8T''' was an {{intel|80486}}-compatible microprocessor introduced by [[AMD]] in 1993. This processor had a clock multiplier of 2 having base frequency of 66 MHz with a bus frequency of 33 MHz. This model is identical to the {{\\|Am486DX2-66V8T}} except for the fact that it was geared toward the embedded market from a company-support standpoint.
