  • Consumable chip and communication method for consumable chip
    Patent number: 11709927
    Abstract: 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.
