Specification

Nuvoton technology is headquartered in Taiwan' s a comprehensive chip design company, specialized in the research and MCU microcontroller consumer IC manufacturing, various pronunciation chip, etc. Nuvoton technology SCM basically has N79E series, W77E series, W78E series, W79E series of chip. Because the early versions of W78E and W79E microcomputer in the design flaws, it is easy to use software attack decryption chip, after manufacturer of chip version to upgrade, the new version of the chip can' t soft decryption, our company can provide a full range of Nuvoton technology microcontroller decryption.
