Embodiment Construction

[0039] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0040] Such as figure 2 As shown, in the embodiment of the method and device for initializing the passive electronic tag memory of the present invention, the initialization method includes the following steps:

[0041]Step S21 sets the initial value of the writing time: in this embodiment, the passive electronic tag is connected to the test equipment when the test is started, as an integrated circuit, when the initialization is not started, there is no data content inside it, only It is a semi-finished product produced on a production line. During the testing process, the memory needs to be initialized and the tag data content is written into the memory, so that the test can be completed and the integrated circuit becomes an electronic tag that can be used in subsequent steps. To this end, in this step, the test device sets the write time value. As m...

Abstract

The invention relates to a method for initializing a passive electronic tag memory. The method comprises the following steps of: setting an initial value of writing-in time; setting a frequency adjusting parameter, adjusting an oscillation frequency value of an oscillator inside a passive electronic tag; obtaining the oscillation frequency value of the internal oscillator, and obtaining a special value of the writing-in time of the passive electronic tag; storing the special value of the writing-in time to a parameter region of the storage, covering the initial value of the writing-in time, and using the special value of the writing-in time as the writing-in time for initializing the passive electronic tag; and initializing the memory of the passive electronic tag, and setting the content for the writing-in of the memory. The invention further relates to a device for implementing the method. The method and the device for initializing the passive electronic tag memory have the beneficial effects that the initializing time is short and relatively fixed.

Description

technical field [0001] The invention relates to the field of radio frequency identification, and more specifically relates to a method and device for initializing a memory of a passive electronic tag. Background technique [0002] Due to its advantages of fast reading speed, long recognition distance, large data capacity and high security, RFID technology is gradually replacing barcode technology and becoming the leading role in Internet of Things applications. The cost of passive electronic tags is the biggest obstacle for RFID technology to replace bar code technology. The test cost of the passive electronic tag chip is an important part of the cost of the passive electronic tag. The testing work of the passive electronic tag chip includes the following contents: initializing the memory, configuring the parameter area, injecting the tag identifier TID and verifying the basic functions of the protocol. In general, the additional resources added to the test circuit should ...
