Some of the annual flagship mobile phones in 2022 rushed to accelerate the debut on the eve of the Spring Festival, although it seems that the time is a bit rushed, but the annual flagship mobile phones released by various manufacturers have come up with their own real skills, of which xiaomi technology positioning in the high-end market is the most representative, and the Xiaomi 12 Pro equipped with Qualcomm Snapdragon 8 Gen1 processor brings a chip developed by Xiaomi - the surging P1.
Since the Millet mobile phone 5C equipped with the Songuo Surging S1 processor, Xiaomi's own chip manufacturer - Pinecone Surging has rarely had new news, until the spring new product conference in March 2021, the appearance of the surging C1 reminded people of Xiaomi's self-developed chip product line, but unlike the surging S1, the surging C1 is not a Soc processor, but a focus on image performance ISP chip, but at least it proves that Xiaomi has been working hard in the direction of self-developed chips.
Xiaomi Mi 12 Pro debuted with the surging P1 chip, this chip is also not a Soc processor that we are very familiar with, but a charging chip, but the role of this chip can not be ignored, because with this chip, you can make xiaomi 12 pro in the charging process of the heat and charging efficiency to achieve the greatest balance, it is precisely because of the surging P1 charging chip, xiaomi 12 pro using the 120W super fast charge has a better user experience.
Surging P1 is the industry's first resonant charging chip, the traditional charge pump usually has a voltage change and straight through two working modes, and the surging P1 to achieve through a single chip to complete six kinds of voltage change mode, combined with the double guide pass, there can be 15 kinds of permutation combination of mode switching, is the traditional charge pump 7 times as much, such a scheme on the one hand so that the application of the surging P1 charging chip terminal products have a more efficient output efficiency, the output efficiency of the official data species reached 96.8%, At the same time, the simplified circuit can effectively avoid concentrating the heating position in the same position, which is conducive to better heat dissipation, and can maintain full power charging for a longer time, while supporting wireless charging.
However, since the release of the surging P1 with the Xiaomi 12 Pro, the questioning of this chip on the network has never stopped, and even some bloggers have bluntly said that Xiaomi's surging P1 chip is not xiaomi's self-developed results, but the chip developed by Nanxin Semiconductor is OEM mass production, for such rumors, Xiaomi's legal department finally began to act in the near future, and Nanxin Semiconductor also issued a rumor-busting statement for xiaomi surging P1 chip.
The general meaning of the statement is that the Xiaomi surging P1 chip is indeed related to Nanxin Semiconductor, but only Nanxin Semiconductor helps Xiaomi to carry out FOUNDC production, as for the rumors that netizens questioned the "Xiaomi OEM South Core SC8571", Nanxin Semiconductor also explained in detail the structure of the two chips, of which the Nanxin SC8571 uses ultra-high voltage 4:2 charging architecture, which can achieve 120W dual-cell charging, supporting 4:2 and 2:2 two modes The Xiaomi surging P1 chip in the internal code name of NANSMicro is SC8561, using ultra-high voltage 4:1 charging architecture, can achieve 120W single cell charging, support 1:1, 2:1 and 4:1 three conversion modes, the internal structure of the two chips and the actual function, product positioning and other aspects are completely different.
