High-speed ink cartridge chip

Abstract

The invention relates to a high-speed ink cartridge chip, which comprises a high voltage sensor signal detecting unit (1) used for receiving HVP and HVN signals and generating a high voltage test signal, a high voltage sensor signal feedback unit (2) used for receiving the high voltage test signal and producing and feeding back an excitation response, a power conversion and control unit (3) used for converting power voltage electrified from the high voltage test signal and an inner communication signal and generating an inner power supply signal, a logic control unit (4) used for receiving the inner power supply signal and the inner communication signal and generating an inner data signal and an inner control signal, a high speed storage unit (5) used for receiving the inner control signal and reading, writing, storing data in a high speed, and a digital communication interface circuit (6) used for treating a digital communication signal and sending the inner communication signal and the inner data signal. According to the high-speed ink cartridge chip disclosed by the invention, an external power source is not needed, the difficulties in the production, the transportation and the storage of ink cartridges are effectively reduced, the stability and the reliability of the ink cartridge data storage are improved, and the high speed storage unit has a quick reading and writing capacity.

Description

technical field [0001] The invention relates to the field of inkjet printers, in particular to a high-speed ink cartridge chip applied to inkjet printers with a communication speed above 10 MHz. Background technique [0002] There is a chip attached to each ink cartridge of the inkjet printer, which communicates with the printer host through the printer word car in use. The chip is used to store original information such as manufacturer information, model, color, and total amount of ink of the corresponding ink cartridge. At the same time, during subsequent use such as switching on and off, replacing ink cartridges, and printing, the printer host will read and write the ink cartridge chip through the relevant interface with a specific communication protocol, thereby detecting and authenticating the ink cartridge, and recording the printing date, number of printed sheets, and ink remaining. Printing information, the printer interacts with the information of the ink cartridge...
