Huawei’s new Pura 70 series of smartphones sold out quickly after its launch last month. Analysts see it as another Apple iPhone challenger and it adds to the signs of how the Chinese company is pushing back against US restrictions.
The Pura series, developed by the Shenzhen company, has advanced cameras and is known for its slim design. In contrast, the Mate 60 series, which marked Huawei’s re-entry into the high-end smartphone market last year, emphasizes performance and business features.
The American iFixit and TechSearch International, which provide product reports down, examined the inside of Huawei Technologies’ Pura 70 Pro for Reuters. Here are the findings:
PROCESSOR CHIP
The Pura 70 phones use an advanced system-on-chip that carries external signals similar to the older Kirin 9000n, the chip used by Huawei’s foundry-produced Mate 60 series Chinese chip Semiconductor Manufacturing International Corp’s (SMIC) 7 nanometer (nm) N +2 production process.
IFixit, TechSearch and other teardown companies call this chip the Kirin 9010.
BROWN CHIPS
Just like the Mate 60, the Pura 70 uses a DRAM chip from South Korea’s SK Hynix.
However, the Pura 70 NAND flash memory chip has indications that it was made by Huawei’s own chip unit, HiSilicon, according to iFixit and TechSearch. For comparison, the Mate 60 used NAND chips from SK Hynix.
The Pura 70 NAND chip has a storage capacity of 1 terabyte (TB) – equivalent to the storage in many high-end laptops – but only has 8 NAND chips, meaning each chip has a capacity of 1 terabit (Tbit ). This compares to products from major foreign flash memory manufacturers such as SK Hynix, Kioxia and Micron.
iFixit said it believes HiSilicon may have produced a NAND chip memory controller.
The density obtained depends on the wafers used in the chip. However, the companies could not definitively identify the manufacturer of the wafer because the markings on the NAND die were not known, although they believe it is a domestic producer, they said.
OTHER SINE RESEARCH MARKS
The Pura 70 Pro phone includes a range of other critical components designed by HiSilicon, such as the WiFi and Bluetooth modules and power management chips.
Components such as audio amplifiers and LED flash drivers come from other domestic suppliers such as Goodix and Awinic.
MURDER MADE BY A STRANGER
However, some parts from foreign suppliers are still in the phone. The battery charger comes from Richtek from Taiwan, and especially the motion and rotation sensor comes from the German company Bosch.
IFixit noted that it was strange that Chinese manufacturers seemed to have the ability to produce these sensors domestically, which raised the question of why a foreign-made one was necessary to use (Reporting by Brenda Goh and David Kirton; Editing by Jacqueline Wong)
