Abstract

The invention discloses an NVM fast coding system of an ultra-high frequency radio frequency chip, the chip includes an analog circuit module, a logic circuit module and an NVM storage area module, and the NVM fast coding system includes an identification bit judging unit, a minimum write power and The maximum write speed switching control unit and the input voltage monitoring unit; the identification bit judging unit includes the identification bit EPC_Lock located in the NVM storage area module; the minimum power and the maximum writing speed switching control unit switch chips according to the value of the identification bit EPC_Lock working mode; the input voltage control unit is provided with a voltage identification bit vld_OK for monitoring the voltage written into the chip in any working mode. The present invention provides an NVM fast coding system for ultra-high frequency radio frequency chips, which can adapt to different application environments and requirements; The operation results in a byte write failure.

Description

technical field [0001] The invention belongs to the field of ultra-high frequency radio frequency chips, and in particular relates to an NVM fast coding system of ultra-high frequency radio frequency chips. Background technique [0002] With the development of RFID (Radio Frequency Identification) UHF technology in the Internet of Things, we will face more and more processing of UHF data, such as retail, inventory and other applications. Due to different application scenarios and application requirements, different requirements are put forward for the code writing speed, group reading capability, and reading distance of the same UHF tag chip. At the same time, with the increasing requirements for the stability of UHF RFID tag writing in market applications, even the 0.1% code writing failure rate needs to be continuously improved and avoided. [0003] In the actual use scenario of massive UHF RF chips, it is mainly divided into factory-level batch data writing (maximum writ...
