An exciting news, Unigroup Zhanrui 5G chip Tiger Ben T7520 SoC has returned to the full Mask in the first quarter of 2021, and will be available 3 months ahead of schedule.
This news is undoubtedly very good news for the domestic mobile phone SoC chip . You know, the Full Mask return means that the chip is about to be put into mass production.
As early as the 4G era, domestic mobile phones used Ziguang Zhanrui chip solution for relatively few smartphones, but in overseas markets, Ziguang Zhanrui is a household name.
International brands such as Samsung, LG, , Nokia and other overseas mobile phones have used Unisplendour Span1span chip extensively. In India, Africa, South America and other markets, Ziguang Zhanrui occupies a large market share. In the Indian market, Ziguang Zhanrui once occupied about 40% of the market. The success of Transsion, the king of mobile phones in Africa, is also inseparable from the help of Ziguang Zhanrui .
However, with the advent of the 5G era, Ziguang Zhanrui chips have dropped significantly, and even fell out of the top ten in the world.
As on May 15, 2020, Ziguang Zhanrui announced the official commercialization of the Tiger Ben T7510 5G chip solution, and the performance of the 5G chip by Ziguang Zhanrui is very outstanding.
2020 global smartphone chip rankings
in the 2020 global smartphone chip rankings, MediaTek's mobile phone chip shipments reached 352 million, an increase of 48% year-on-year, and the market share reached 27%, surpassing Qualcomm;
and Unisplendour Sharp will rise in 2020, with chip shipments Reached 23 million, an increase of 89% year-on-year, and its market share rose to 2% globally.
Here, let’s briefly understand the chip manufacturing process:
1. Tape out ( Tape Out ):
belongs to a factoryless manufacturer in the industry. Fabless. Such companies are only responsible for chip design and sales; chip production, testing, packaging, etc. are all outsourced. There are many such chip companies, such as Qualcomm, Huawei HiSilicon, MediaTek, Broadcom and so on.
GDSII file
After the chip design is completed, the designer generally needs to deliver the designed circuit layout to the foundry in GDSII format. This is tape-out or cast-out.
2. mask (Mask)
delivery data
firstly need to copy this flow slice to a piece of semiconductor circuit _span by various methods. on.
This process is similar to the photosensitive dry film method used in our DIY circuit boards. It requires photosensitive glue, wiring to cover the wiring, corrosion of copper foil and so on.
The semiconductor thin film can not be used in the traditional way, it needs to use a large number of masks in the manufacturing process to complete.
reticle mask
photomask was originally a reticle mask, which was engraved on a 4-9" quartz glass plate coated with a chromium layer by a laser beam, and then stepped Into the machine, the original version is reduced to the master mask (master maks), which is the working mask in the actual exposure.
3. full mask ( Full Mask)
reticle Mask
In the chip, as everyone knows, nowadays mobile phone Soc chips are becoming more and more complex, and there are more and more masks, and the cost is doubled. is generally only available in Soc chips The full mask will only be used when the design test is completely successful and ready for mass production. When preparing for commercial use, the full mask will be used.
. The design company commissioned by the OEM, the design company will go through the testing of the chip performance,Prepare for the next batch of production.
And Huben T7520 SoC this time the Full Mask return, once again proves the good news of its upcoming mass production.
Unisplendour 5G chip road
Huben T710
In February 2019, Unisplendour released its completely self-developed 5G technology platform and launched the 2510 base chip + The tiger ben T7510 5G SoC chip combined with the tiger ben T710 application processor.
The first-generation 5G chip T7510 of Unigroup Zhanrui adopts TSMC’s 12nm process foundry, and is used in domestic Hisense F50 China Telecom Tianyi No. 1 2021 and other 5G mobile phones.
This means that in the 5G era, the gap between and the industry-leading level of has been shortened to less than 6 months. It has also become the fifth company in the world that can independently design 5G SoC chips, and it is also the only company in mainland China. A company that sells 5G SoC chips, ranks among the world's first echelon.
T7520 SoC
On February 26, 2020, Ziguang Zhanrui released its latest Huben T7520 5G SoC chip. originally planned to use TSMC’s 7nm process as early as 2018. Produced 7nm process chips, compared with 16nm process, 7nm transistor speed increased by 40%,The power consumption is reduced by 65% under the same performance. In 2019, TSMC announced the launch of the 6nm EUV process. It began to use the EUV process in the 7nm process, which increased the transistor density by 18%, reduced the power consumption by 8%, and the design was also compatible with 7nm. Therefore, Ziguang Zhanrui chose the 6nm EUV process to manufacture the Tiger Ben T7520 SoC.
Huben T7520 SoC
architecture: Huben T7520 integrates eight CPU cores, including four A76, four A55, and four Mali-G57 GPU graphics cores at the same time. 2×16-bit LPDDR4X 2133MHz, storage support eMMC 5.1, UFS 3.0.
baseband system:
Tiger Ben T 7520 integrates , the world’s first full-scene coverage enhanced 5G baseband, supporting frequency bands below 6GHz, NSA/SA dual-module network, 2G to 5G seven-mode full Netcom, dual card dual Advanced standards and technologies such as 5G, EPS fallback, and VoNR HD voice and video calls support 5G NR TDD+FDD carrier aggregation. The SA mode downlink peak rate can exceed 3.25Gbps, and the upload can reach 1.25Gbps.
camera system :
Tiger Ben T 7520 has powerful image processing capabilities. It uses a quad-core ISP for the first time in a 5G chip. The quad-core ISP processing speed is up to 1.5 billion pixels per second and can support up to 1.08 shooting. 100 million pixel photos, single-shot zero-delay photography up to 64 million pixels.Through the sixth-generation image engine Vivimagic solution independently developed by Ziguang Zhanrui, with the blessing of the second-generation FDR technology, seamless zoom shooting of three-shot/four-shot scenes is realized, using FRC technology, and with the help of Vision DSP acceleration, 960fps can be achieved 720P HD slow motion video shooting, and supports 240fps 1080P, and supports up to 480fps 720P unlimited time HD slow motion shooting.
gathers a lot of Ziguang Zhanrui's self-developed technologies. The preparation of the Huben T 7520 5G SoC chip for mass production is of practical significance for solving the temporary shortage of global chips.
And the mass production of the Huben T 7520 5G SoC chip seems to be a small step for the domestic mobile phone SoC chip. But it undoubtedly proves that our domestic mobile phone SoC chip is not without technology, but depends on whether you have the confidence to stick to it!
lags behind its opponents by 15 years in the 2G era, 8 years behind its opponents in the 3G era, and 10 years behind its opponents in the 4G era. In the 5G era, it catches up to only 6 months behind its opponents and ranks first in the world.
Tsinghua Unisplendour presents a true portrayal of our independent research and development of the chip industry and catching up with the world's top level!
Come on! Ziguang Zhanrui.
