Galaxy-CAS | Under the heavy pressure of tariffs, the rise of domestic production is at the right time

The tariff war between China and the United States is gradually entering a white hot stage, and the semiconductor industry is experiencing undercurrents. Whether it is the implementation of equivalent tariffs, changes in rules of origin determination, or adjustments to tariffs in the semiconductor industry, they all affect the global pattern of the semiconductor industry. No matter how the external environment changes, the trend of domestic substitution remains unwavering, which also brings unprecedented market opportunities for domestic analog chips.

The analog chip industry has a unique development model, with many analog chip manufacturers adopting the IDM model. Among them, the top ten global analog chip manufacturers represented by TI and ADI are the most typical. Some manufacturers encounter the dilemma of "no quotation, no order" when preparing materials and placing orders. In this situation, domestic substitution has become imperative. Beijing Galaxy-CAS Technology Co., Ltd., as a cutting-edge enterprise focusing on the subdivision of analog signal chain chips, has achieved complete functional replacement of TI and ADI (MAXIM) related products in chip products such as temperature, humidity, single bus secure storage, and interface circuits.

Galaxy-CAS was established in 2018, focusing on the design and development of chips for temperature, humidity, safety certification, interfaces, signal conditioning, motor drives, clocks, pressure, current monitoring, and more. The company always adheres to independent innovation, and all IPs are self-developed, achieving true autonomy and controllability. In terms of product development, Galaxy Core has become the preferred high-quality manufacturer for the localization of high-end environmental sensors, relying on ten years of technical accumulation and standardized management of the entire process of process, quality, quality control, and testing.

In the domestic substitute products of Galaxy-CAS, we have compiled some product series that can be quickly and directly replaced for your reference:

1 Single bus safety certification series products

The GX2431 series of single bus safety certification chips can directly replace ADI's (MAXIM) DS2431 series products in P2P, and its performance parameters and packaging form are superior to similar foreign products in the same series. This chip has a 1024 bit EEPROM storage space and can operate within a temperature range of -55 ℃~+125 ℃ and a wide voltage range of 2.5V~5.5V. It can adapt to various extreme temperature environments such as high-temperature industrial production and low-temperature outdoor operations. For storing important device parameters, authentication information, and other key data, it enhances data security and stability, prevents data and information from being tampered with arbitrarily, and improves the product's ID security authentication function.

The GX28E01 series of single bus encryption and authentication chips can directly replace ADI's (MAXIM) DS28E01 series products in P2P. It is a highly reliable encryption and authentication chip that combines 1024 bit EEFORM with SHA-1 secure hash algorithm that complies with the ISO/IEC 10118-3 standard to query and respond to secure authentication functions. Adopting a single bus communication protocol, the maximum transmission rate reaches 125kbps, with 1024 bit storage space to meet diverse data storage needs. The static current is as low as 1 μ A or less, balancing high efficiency and energy saving. Widely applicable in fields such as FPGA encryption, instrument and equipment identity authentication, intellectual property protection, smart card encryption, program copyright protection, and consumables anti-counterfeiting.

2. High precision temperature sensor chip series products

The temperature sensors independently developed by Galaxy-CAS cover a range of digital and analog products, and the digital temperature IC can provide a single bus interface I2C/SMBus、SPI、UART、 Single line pulse and other multi series interface product lines, temperature measurement range covers from -80 ℃ to+200 ℃, accuracy from 0.1 ℃ to 1 ℃, resolution from 9bit to 16bit, meeting various temperature measurement needs of different users. One of the high-precision human body temperature measurement chips, GXT311, can replace MAX31725/31726. The product comprehensively benchmarks international leading products in core indicators such as temperature measurement accuracy, response speed, and long-term stability. Adopting a 16 bit (0.0078125 ℃) temperature output, the instantaneous power consumption can reach 5uA, with a typical accuracy of ± 0.1 ℃ and a minimum size of only 0.7mmx0.9mm. It is packaged in a small volume WLCSP, which is not only suitable for applications with extremely limited space, but also has rapid heat transfer. It is particularly suitable for temperature monitoring in electronic medical grade fields such as wearable products such as watches, bracelets, rings, and electronic thermometers.

3. Single chip integrated temperature and humidity sensor chip series products

In the field of temperature and humidity sensors, Galaxy-CAS has achieved greater breakthroughs. The single chip integrated temperature and humidity sensor series products GXHT3X and GXHT4X launched not only successfully solve the industry pain points of traditional sensor accuracy degradation and severe temperature drift, but also break the monopoly of traditional chips in industrial, home appliance and other application scenarios with a wide temperature range of -40 ℃ to 130 ℃. In high-end application scenarios such as smart grain and white goods, the stable and reliable performance of GXHT3X series sensors provides key support for domestic equipment to achieve full chain autonomous controllability. It is worth mentioning that the product has passed the AEC-Q100 automotive grade certification and successfully entered the supply chain of a certain automotive company, marking the official entry of domestic temperature and humidity sensors into the international first-class level.

The localization substitution practice of Galaxy-CAS is not only a victory of technological innovation, but also a model of coordinated development of industrial ecology. The company has overcome multiple key technical challenges in single-chip integrated temperature and humidity MEMS technology, signal conditioning circuits, and successfully transformed its independent technological advantages into industry discourse power. Nowadays, Galaxy-CAS's products have been widely used in national key development fields such as white goods, smart food, communication servers, photovoltaic energy, electricity, medical care, and automobiles. The cumulative shipment volume has exceeded hundreds of millions, laying a solid "Chinese chip" defense line for the security of the industrial chain. In response to the impact of this tariff, in order to help everyone better achieve domestic substitution, the editor has compiled a compatibility table of domestic products that can be replaced by Galaxy-CAS.
