As the ban on disposable e-cigarettes in the European Union and other regions gradually takes effect, the global e-cigarette market is accelerating its transition to replaceable cartridge products.

At the same time, the rise of the intelligent trend has put forward higher requirements for product functions: the cartridge part needs to record key data such as the type of e-liquid, the remaining amount of e-liquid, and production information, while the cigarette holder needs to have intelligent authentication capabilities to identify the authenticity of the cartridge and prevent the circulation of counterfeit and inferior products. This is not only to ensure the quality of consumer experience, but also to protect the commercial interests of merchants.

In this context, the demand for electronic cigarette anti-counterfeiting is becoming increasingly urgent. Recently, domestic semiconductor company Runjetic announced the launch of the RJGT106 anti-counterfeiting encryption chip designed specifically for two-contact electronic cigarettes, providing the industry with a set of efficient and reliable solutions.

两触点电子烟烟弹防伪加密芯片RJGT106

RJGT106是一款支持正/反插与计次功能的高性能防复制加密芯片。其集成了256Byte 的 EEPROM（包含16 Byte的密钥和8Byte 的 UID），执行 RC4 算法认证，与MCU可通过INA/INB单总线接口通信。功耗极低，正常工作功耗小于0.2mA@NOP，低功耗模式小于500nA。RJGT106支持宽的工作电压2.2V-5.0V。RJGT106的防静电保护ESD（HBM）达8KV。

• 支持两线正反插
• 所需安装空间小，DFN-6(2mm×2mm)小封装
• 烟杆端和烟弹端电路简洁，所需电子器件少
• 高安全性，RC4加密算法
• 轻量级RC4加密认证算法，占用MCU资源少，运行时间短，主流MCU均适用。
