The paper presents a cryptographic smart password control based on MCU, describes hardware structure and software design of the system. The circuit realizes the intelligent control core which the password locks, it is uses for to complete the password the input, the judgment and the comparison and the execution corresponding next function like unlocks. The password input uses 4×4 the determinant keyboard. Through seven sections of digital tubed to show the correct password. KeyWords:Password control; Single-chip; matrix keyboard; Alarm 目录
