Description

Technical Field

[0001] The invention relates to the field of single chip computer storage units, in particular to a programmable OTP storage unit and a data protection method thereof. Background Art

[0002] OTP (One Time Programmable) is a type of memory for microcontrollers, which means one-time programmable: after the program is burned into the microcontroller, it cannot be changed or cleared again. OTP type registers can only be programmed once, and cannot be modified after programming. Through the OTP register and the LOCK register, users can save some specific information in the OTP, such as software version number, hardware version number, secret key and other information. There will be another OTP register inside this type of FLASH chip. This register has been programmed by the manufacturer when it was produced, and a specific serial number is written and locked. If necessary, the FLASH manufacturer can also write a specific serial number according to the needs of the customer, so that each chip will have a different ID number to avoid being copied. The OTP storage chip is to protect the hardware design on the one hand, and on the other hand, it is also for the safety of the product itself to prevent being hacked.

[0003] Existing electronic devices may have working areas that are too humid due to climate reasons, and moisture may enter the interior of the electronic device. When moisture invades the interior of the electronic device for a long time and is not removed, the moisture will adhere to the outer surface and pins of the OTP storage chip, causing the OTP storage chip to malfunction or short-circuit. If the OTP storage chip is damaged, the security serial number of the electronic device will be lost. The loss of confidential data inside the electronic device will cause a large and irreversible impact. To this end, we propose a programmable OTP storage unit and a data protection method thereof.

At the same time, part of the high-speed airflow is directly blown to the inside of the integrated circuit base under the action of the air guide sleeve, so as to effectively dehumidify the connection between the OTP storage chip and the integrated circuit base.

[0036] See also Figure 5 In the figure, sliders are fixedly installed on both sides of the OTP storage chip 5, and the sliders are slidably embedded in the inner side of the fixing frame 15. The sliding engagement between the sliders and the fixing frame 15 can ensure the stability of the up and down movement of the OTP storage chip 5.

[0037] A data protection method for a programmable OTP storage unit, the method comprising the following steps:

[0038] S1. In the dehumidification stage, after the moisture around the electronic board 2 reaches the rated value set by the humidity sensor 4, the dehumidification fan 3 can be started. The wind blown by the dehumidification fan 3 can blow away the moisture around the electronic board 2 and evaporate it quickly. Part of the high-speed airflow at the air outlet of the dehumidification fan 3 flows into the interior of the integrated circuit base 6 through the air guide plate 13 under the action of the receiving port 14;

[0039] S2. The OTP storage chip 5 is separated from the integrated circuit base 6. To ensure that the OTP storage chip 5 is quickly separated from the danger of moisture erosion, the dehumidifying fan 3 is started to drive the fixed disk 22 to rotate through the transmission belt 23. During the high-speed rotation of the fixed disk 22, the counterweight block 33 and the limit groove 34 can stretch the tension spring 35 under the action of centrifugal force, so that the movable tooth 30 extends out of the fixed disk 22 and drives the rotating disk 17 to rotate through the rotating member 12. The rotating disk 17 can rotate clockwise by a certain angle under the action of the reset member 10, and the limit inclined block 29 inside the rotating disk 17 will no longer squeeze the connecting column 28. The OTP storage chip 5 will move upward and separate from the integrated circuit base 6 under the action of the spring 16;

[0040] The high-speed airflow guided by the air guide sleeve 13 in S3.S1 passes through the connecting groove 24 inside the integrated circuit base 6, so that the high-speed airflow flows in each plug hole inside the integrated circuit base 6 and flows upward. The high-speed airflow can effectively remove moisture from the connection between the integrated circuit base 6 and the OTP storage chip 5, thereby ensuring the safety of the OTP storage chip 5.

[0041] The working principle of preventing moisture from affecting the OTP storage chip 5 is as follows: when the electronic device is in operation, if the surrounding moisture increases, the moisture will enter the interior of the mounting frame 1. When the moisture inside the mounting frame 1 reaches the safety value set by the humidity sensor 4, the dehumidifying fan 3 can be started. During the operation of the dehumidifying fan 3, the fixed disk 22 can be driven to rotate at high speed through the transmission belt 23. The counterweight block 33 and the movable teeth 30 inside the fixed disk 22 can stretch the tension spring 35 under the action of centrifugal force. After several groups of movable teeth 30 are extended, they can mesh with the gear 2 21 for rotation. The rotation of the gear 2 21 can drive the gear 1 20 to rotate through the rotating shaft 1 31, and the gear 1 20 can drive the rotating disk 1 through the limiting teeth 18. 7 is rotated clockwise. Under the action of the reset member 10, the turntable 17 can be limited after being rotated to a certain angle. After the turntable 17 is limited, its gear 1 20 and the shaft 1 31 cannot rotate. At this time, the gear 21 continues to rotate under the transmission of the movable tooth 30. After the limiting top column 38 is subjected to a large pressure, it will retract to the inside of the shaft 1 31 and no longer mesh with the semicircular groove 36 to make the gear 1 20 rotate. After the turntable 17 stops rotating at a certain angle, the limiting inclined block 29 inside it will no longer squeeze the connecting column 28 after following the turntable 17 to rotate at a certain angle, so that the OTP storage chip 5 moves upward under the action of the spring 16, and its pins are completely separated from the integrated circuit base 6;

[0042] The purpose of the separation is that the moisture inside the mounting frame 1 has reached a level that can affect the normal use of the electronic components, and the dehumidification effect of the dehumidification fan 3 will not take effect immediately, and it will take a certain amount of time. The OTP storage chip 5 is completely separated from the electronic board 2 at the moment the dehumidification fan 3 is started, in order to ensure that the OTP storage chip 5 will not be short-circuited or other faults will occur due to the influence of moisture, resulting in the loss of internal confidential data. At the same time, after the OTP storage chip 5 is lifted, part of the wind force of the dehumidification fan 3 can be used to send air to the inside of the integrated circuit base 6 under the action of the air guide mechanism 7, and the connection between the integrated circuit base 6 and the OTP storage chip 5 is dehumidified to ensure the safety of the use of the OTP storage chip 5;

[0043] In actual application, the transmission mechanism 11, the limit member 9, the reset member 10 and the rotating member 12 are all installed on the upper end surface inside the mounting frame 1, and there is a large gap between them and the electronic components on the electronic board 2, which will not affect the normal use of the electronic components.

[0044] Example 2

[0045] See also Figure 3 and Figure 4 The present embodiment further explains Example 1, the air guide mechanism 7 includes an air guide sleeve 13 fixedly mounted on the upper end of the electronic board 2, a receiving port 14 is fixedly mounted on one end of the air guide sleeve 13 close to the air outlet of the dehumidification fan 3, and the other end of the air guide sleeve 13 is movably fitted with the integrated circuit base 6, a connecting groove 24 is opened on the inner side of the integrated circuit base 6, and the connecting groove 24 is communicated with the internal jack of the integrated circuit base 6, and the end of the connecting groove 24 close to the air guide sleeve 13 is communicated with the air guide sleeve 13.

[0046] In this embodiment: under the guidance of the receiving port 14 and the air guide sleeve 13, part of the wind force generated by the moisture-removing fan 3 will be transmitted to the interior of the integrated circuit base 6, and under the action of the connecting channel 24, the high-speed airflow can flow through each socket inside the integrated circuit base 6 and blow out from the upper end of the socket, thereby effectively dehumidifying the pin connection between the integrated circuit base 6 and the OTP storage chip 5.

[0047] Example 3

[0048] See also Figure 5, implementation mode is further described for other embodiments, the reset member 10 includes a fixed plate 26 fixedly mounted on the upper end surface of the turntable 17, and a fixed arc tube 19 is installed on the side end of the fixed plate 26, the fixed arc tube 19 is fixedly connected to the mounting outer frame 1 through a fixed rod, an arc push rod 25 is movably embedded in the inner side of the fixed arc tube 19, and one end of the arc push rod 25 close to the fixed plate 26 is fixedly embedded in the inner side of the fixed plate 26, and a spring 27 is installed at one end of the arc push rod 25 away from the fixed plate 26. After dehumidification is completed, the elastic force generated by the spring 27 can reset the turntable 17, so that the turntable 17 squeezes the connecting column 28 again.

[0049] In this embodiment: during the clockwise rotation of the turntable 17, the arc-shaped push rod 25 can be moved toward the inside of the fixed arc tube 19 and push the spring 27. After the spring 27 is compressed to the maximum value, the turntable 17 can be limited. After the dehumidification fan 3 stops running, that is, the transmission mechanism 11 and the rotating member 12 stop running, the rotating member 12 is no longer restricted. Under the thrust generated by the spring 27, the arc-shaped push rod 25 can push the turntable 17 to reset, and at the same time squeeze the connecting column 28 again to connect the OTP storage chip 5 with the integrated circuit base 6.

3. The programmable OTP storage unit according to claim 1, characterized in that: Slide blocks are fixedly mounted on both the left and right sides of the OTP storage chip (5), and the slide blocks are slidably embedded in the inner side of the fixing frame (15).

4. A data protection method for a programmable OTP storage unit, characterized in that: The method comprises the following steps: S1. In the dehumidification stage, after the moisture around the electronic board (2) reaches the rated value set by the humidity sensor (4), the dehumidification fan (3) can be started. The wind blown by the dehumidification fan (3) can blow away the moisture around the electronic board (2) and evaporate it quickly. Part of the high-speed airflow at the air outlet of the dehumidification fan (3) flows into the interior of the integrated circuit base (6) through the air guide sleeve (13) under the action of the receiving port (14); S2. In the stage where the OTP storage chip (5) is separated from the integrated circuit base (6), in order to ensure that the OTP storage chip (5) is quickly separated from the danger of moisture erosion, the dehumidification fan (3) is started to drive the fixed disk (22) to rotate through the transmission belt (23). During the high-speed rotation of the fixed disk (22), the counterweight block (33) and the limit groove (34) can stretch the tension spring (35) under the action of centrifugal force, so that the movable tooth (30) extends out of the fixed disk (22) and drives the rotating disk (17) to rotate through the rotating member (12). The rotating disk (17) can rotate clockwise by a certain angle under the action of the reset member (10), and the limit inclined block (29) inside the rotating disk (17) will no longer squeeze the connecting column (28). The OTP storage chip (5) will move upward under the action of the spring 1 (16) and separate from the integrated circuit base (6); The high-speed airflow guided by the air guide sleeve (13) in S3.S1 passes through the connecting groove (24) inside the integrated circuit base (6), so that the high-speed airflow flows in each plug hole inside the integrated circuit base (6) and flows out upward. The high-speed airflow can effectively remove moisture from the connection between the integrated circuit base (6) and the OTP storage chip (5), thereby ensuring the safety of the OTP storage chip (5).
