Air Microelectronics releases the AT60LF series of 60G millimeter wave radar chips, with power consumption as low as uA level!​

Zhang Zhenwei, vice president of sales of Space Microelectronics (Shenzhen) Co., Ltd., released the world's first uA-level ultra-low power consumption 60G millimeter wave radar SoC series chip AT60LF at this forum.

As a chip design company established in 2017, Space Intelligence focuses on high-performance wireless radio frequency, microwave millimeter wave, radar sensors, low-power MCU and SoC technology. It can provide a complete set of chips, modules, algorithms, software and even smart terminals. solution.

According to Zhang Zhenwei, the current air-to-air microelectronic radar product line has covered the full frequency bands of 5.8GHz, 10.525GHz, 24GHz, 60GHz, and 77GHz. It not only has "BLE+ radar" dual-mode chips, vehicle-mounted millimeter wave radar chips, but also integrated Dedicated MCU+radar SoC and other products have been widely used in intelligent Internet of Things (AloT), smart lighting, smart home appliances, smart home, smart city management, automotive ADAS and other fields.


The AT60LF series chip released by Space Microelectronics at this forum is claimed to be "the world's first uA-level ultra-low power consumption 60G millimeter wave radar SoC series chip", with a frequency sweep bandwidth of up to 5GHz. It has 8 built-in composite waveforms, supports frequency hopping and independent chirp signal BPM, etc. It also has built-in hardware accelerator, supports time domain anti-interference detection and suppression, and supports FFT, CFAR, CFAR-zero Doppler and CFAR-range-Doppler parameters. Features such as independent configuration. In terms of antennas, the AT60LF series not only supports multiple antenna configurations, including one transmitter and one receiver, one transmitter and two receivers, two transmitters and four receivers, etc., but also provides AiP built-in antenna and external antenna versions. In addition, the AT60LF series also has built-in high-performance 32-bit MCU to support secondary development. What’s more outstanding is that its power consumption can be as low as 0.1mW. If the voltage is 5V, then this will be the 60GHz millimeter wave radar chip with the lowest power consumption currently.​

Do we know which fab exactly makes Huawei's Kirin 9000s/9010 chips? Is there an exact company name or gps coordinate for it?

I've heard some people say Huawei actually owns the fab with tech from SMIC?

I would rather this information not be made known. A survey of prior discussions here may provide an answer. There's no guarantee that it's the true location though. I might be acting too carefully, but this information can be used by certain groups. Does it truly matter what specific location it's made in? The GPS coordinates? No, just that it's a massive accomplishment that defies all the "experts".

Article from February 2024. The headline is irrelevant, but the data provided is useful to understand a baseline of what Western "experts" believe. SMIC and Chinese domestic producers are far ahead of this baseline, of course, as shown in the Pura 70.

Amid the US sanctions, the indigenization in the chip ecosystem in China has accelerated. According to data from the China Electronic Production Equipment Industry Association (CEPEA), in 2021, locally produced semiconductor equipment sales accounted for 20.02% of the semiconductor equipment sales in China. In October 2023, South Korean media Ddaily quoted industry sources saying that China has doubled its localization rate to over 40%, with the localization rate of PVD and oxidation equipment over 50%.

Regarding semiconductor materials, Fong Li, deputy director at the Shanghai Industrial Technology Research Institute, said the localization rate in the semiconductor materials in China was about 25%, adding that the bulk gases and target materials have higher localization rates than resistors, masks, and reticles, reports Security Times China.

Location	Supplier base	Supplier facilities	Share of supplier facilities (%)
US	11	281	23.17
China	34	224	18.47
Taiwan	7	113	9.32
Germany	2	68	5.61
Others	12	527	43.43

Willing to provide the highlights of this (admittedly bullshit) article? Most recent update on SMIC from Dtimes.

Sure.

Avoiding posting the article directly into the forums due to potential copyright issues. Digitimes says it adds 100K wpm of 28nm and larger. No mention of 5nm or 7nm capacity.

If there are any other paywalls you're having issues with besides Digitimes I may be able to help as well.

Ah thanks!
I'm quite sure its manufacturing 7nm chip in that Fab since they want to avoid restrictions into getting the tools required from AMAT, LAM & KLA and just calls it 28nm Fab

I don't think SMIC can get US made tools even for their 28nm fabs, they still can get Japanese, Euro and obviously local made tools.

Well a large proportion of US Companies Revenue came from Mainland China (40% or more for AMAT, LAM & KLA). SMIC got to be the beneficiary of at least some of them

i still don't understand why you always so eager to read such a low quality articles all time @Wahid145 .. those Nikkeiasia articles are also useless

Shanghai fab has nothing to do with 28nm.. neither they are getting any American tools from October 2022 sanctions onward.. most of the tools SMIC getting is from domestic companies and then Japanese/European.

LAM basically replaced by AMEC.. but KLA still have share in mainland. SMIC is not getting any of tool from KLA for advanced nodes. they are getting most of the tools from local suppliers.

Photoresists upto 14nm serial production has begun. officially announced by state media.. and soon for 7nm too so Japan share in chemicals soon to be vanish ..

Stockpiling by many companies apart from SMIC, the company is in the crosshair by the stooges in DC, especially now that they are collaborating with Huawei.

SMIC is by far the largest capex among Chinese fabs, it is unlikely other fabs in China can attribute 44% of global tools sales
