Provided is a consumable chip and a communication method thereof. The method is adopted for a consumable chip including a first consumable MCU unit, a verification cryptographic operation unit and a second consumable MCU unit; the method includes: when the first consumable MCU unit is incompatible with the printer, the first consumable MCU unit activating the second consumable MCU unit to execute a second consumable chip core processing flow, and calling the verification cryptographic algorithm function program of the verification cryptographic operation unit to calculate a new verification password; after the first consumable MCU unit inquires that the second consumable MCU unit has completed the second consumable chip core processing flow, the first consumable MCU unit reading the new verification password and sending to the printer, the new verification password is received by the printer to achieve compatibility between the first consumable MCU unit and the printer.

Consumable chip and communication method for consumable chip

The application provides an ink cartridge chip, an ink cartridge and an operation method for giving response to printing work, and belongs to the technical field of printing. The ink cartridge chip comprises a storage module at least provided with a first ink quantity data block and a second ink quantity data block which share data with a printer and make the printer have one printing mode, wherein the first ink quantity data block is fixed in the printing mode, and the second ink quantity data block is variable in the printing mode. The ink cartridge comprises the ink cartridge chip. The application with a printing system is easy, convenient and fast, universality is high, printing at a high ink utilization rate is achieved in one printing mode, and the problems of resource waste, consumable loss, high cost and the like are solved.
