Recently, the charging head network learned from the supply chain that Zhirong Technology, a well-known chip brand in the industry, announced that its protocol chip sw2325 has added support for the UFCS fusion fast charging specification, becoming the industry's first protocol chip that supports the UFCS fusion fast charging specification.
UFCS fusion fast charging specification full name "mobile terminal fusion fast charging technical specifications", which is China's first fast charging technology standard, issued by the telecommunications terminal industry association, aims to solve the problem of a wide range of fast charging standards on the market and incompatible with each other, while improving the versatility of the charger.
The full name of the mobile terminal fusion fast charging technical specification is the universal fast charging specification, which is led by the Green Energy Working Group (WG10), led by the Academy of Information and Communications Technology, Huawei, oppo, vivo, and xiaomi, and has been strongly supported by a number of terminals, chip companies and industry partners.
It is understood that Zhirong sw2325 is a very powerful fast charging protocol controller, with a built-in arm m0 core with a 40mhz main frequency and a built-in 64k eflash+4k ram. Supports an ultra-wide input voltage range of 3-30v. Support optocoupler feedback, fb feedback and i2c feedback three kinds of voltage regulation methods, adapt to car charging, charger and other applications.
Sw2325 supports multiple protection functions, supports online upgrades, supports multi-layer nested encryption algorithms, supports nmos or pmos path pipes, and integrates cc/cv loops, which is powerful and comprehensive.
Precisely because sw2325 embeds a core with a maximum operating frequency of 40mhz arm cortex-m0, and its powerful floating-point operation capabilities can efficiently execute special algorithms, sw2325 can support the flexible definition of private algorithms and the porting of encrypted packets. The support for ufcs fusion fast charging specification is precisely because of its own performance plus mass storage support, which can achieve extended protocol support, not only can support multiple proprietary protocols, but also add new protocol support.
Zhirong SW2325 integrates type-c interface logic, USB PD phy, vooc/scp phy, and qc/pe/sfcp/tcn and other fast charging protocol detection circuits, and integrates optocoupler feedback and fb feedback drive circuits, nmos and pmos driver circuits, and cv/cc control loops.
The sw2325 has a variety of built-in security functions. Combined with acdc or dcdc and a small number of peripheral components, a complete high-performance type-c port/type-a-port fast charging solution can be formed.
Charging head net summary
The birth of fast charging technology integrated with mobile terminals can make each family's private fast charging be realized with a charger. The mobile terminal integrates fast charging technology in order to reduce the fragmentation of fast charging, reduce the waste of charger after upgrading, and ensure the user's fast charging experience without the need to purchase a special charger. For third-party chargers is a good thing, for users, you can also use a charger to meet both mobile phone fast charging and laptop charging.
The sw2325 launched by Zhirong can support almost all fast charging protocols on the market, and supports burning updated fast charging protocols. It can be said that it meets the requirements of the fast charging protocol for the protocol chip and creates a charger with very good compatibility. In the future, the restriction of the charger will no longer be the protocol support limit of the protocol chip, but the limit of the factory power.
The advancement of protocol chips has really allowed chargers to update firmware like other peripherals, upgrade protocols, and adapt to changes in mobile devices such as mobile phones. The upgrade of this fast charging protocol can be upgraded through the data cable and the use of mobile phones, so as to achieve insensitive upgrades and support for the latest fast charging protocols, thereby reducing incompatible chargers and achieving a comprehensive and excellent fast charging experience.
