Embodiment Construction

[0028] Below in conjunction with accompanying drawing, the present invention will be described in further detail:

[0029] According to the chip programming socket of the present invention, an MCU is loaded on the programming socket, and an encryption algorithm is programmed in the MCU.

[0030] In this embodiment, the MCU adopts a single-chip microcomputer modeled as STC15F100, which is loaded on the bottom plate of the programming socket. The pin connection diagram of STC15F100 microcontroller is as follows Figure 1-3 shown. Provide a 5V power supply through the base board of the programming seat, and connect it to the microcontroller through a 10uF capacitor, which eliminates power supply noise and improves the anti-interference ability of the entire system.

[0031] The encryption algorithm adopts standard DES. The DES encryption algorithm is a block encryption algorithm, and the plaintext is divided into blocks in units of 64 bits. The 64-bit data is under the contro...

Abstract

The invention relates to a chip burning base and method. An MCU (Microprogrammed Control Unit) is loaded on the burning base, an encryption algorithm is burnt in the MCU, wherein the burning method comprises the following steps of: 1, selecting a chip model to be burnt on an upper computer interface, after selection is completed, sending model data corresponding to a chip to a burner by an upper computer; 2, placing the burning base on the burner, decrypting the model data of the burning base, stored in the MCU, by the MCU on the burning base, sending the decrypted model data to a burner platform; 3, respectively reading data sent by the upper computer and data sent by the MCU by the burner platform, comparing wherein the data sent by the upper computer and the data sent by the MCU are matched; 4, when carrying out once burning process, sending a signal for carrying out burning to the MCU on the burning base by the burner platform; and 5, if the MCU receives the signal for carrying out burning, sent by the burner platform, starting a counting mechanism inside the burner platform, completing once counting. The chip burning base has an encryption function and can effectively ensure burning quality.

Description

technical field [0001] The invention relates to a chip programming socket, in particular to a chip programming socket with an encryption function, and also to a chip programming method. Background technique [0002] There are many ways to program chips, but in mass production, the programmer is still the main method. If you use a programmer to burn, you must use the burner socket. At present, no encryption mechanism is used on the burning socket. In this way, the usage times of each programming socket cannot be effectively monitored. Once the service life of the programming socket is exceeded, there is no way to guarantee the programming quality of the chip. Moreover, the programming socket at this time does not have the function of detecting whether the programming socket matches the chip to be programmed. Contents of the invention [0003] The technical problems of the present invention are: to overcome the deficiencies of the prior art, to provide a chip programming ...
