PURPOSE: An ultra low power door is provided to have an excellent effect that it is used above at least 9,600 - 15,000 times when initial 4 number of 1.5V battery are set on the power block. CONSTITUTION: An ultra low power door includes a microcomputer(10), a memory(70), a motor(90) and a main slip mode switch(SM). The microcomputer(10) controls LCD display block(31) a voice output block(32) and motor driver(40) by receiving the power from the power block(20). The memory(70) stores the signal of the RF card(51) through the RF recognition block(50) for authenticating through the microcomputer(10) and the signal of the key pad(60). The motor(90) drives the lock/unlock unit(80) when it is forward driven or backward driven by the motor driver(40). And, the main slip mode switch(SM) performs the cut-off of the overall power of the power block(20) when the microcomputer(10) does not operate.
