The invention provides a chip of a consumable container, which comprises a storage module, a control module, an interface module and a data safety module. The storage module is used for storing initial data, printing data, control data and key data; the interface module is used for realizing data communication between the storage module and the control module; the data safety module is respectively connected with the interface module and the control module, and is used for identifying a type and a content of data communicated between a printer and the chip, encrypting matched data in a selected safe mode and decrypting the data; the control module is connected with the storage module and is used for controlling data communication between the chip and the printer and the access operation of the data of the storage module and external data and sending a corresponding control command to the chip according to a safety module processing result so as to realize data communication; and the same keys are stored in the printer and the chip. The invention also provides a data communication method for the chip, the consumable container with the chip structure, and imaging equipment with the consumable container. The safety of the communication data of the chip can be protected.
