From May 15 to 17, the 11th China Guangzhou International Automobile Technology Exhibition (AUTO TECH 2024) was held in GuangzhouPoly World Trade CenterGrandly hold。Opening day, siteCrowded, enthusiastic and extraordinary, more than 5,000 professional visitors, showing the vigorous vitality of the automobile industry。Core Sea Technology (stock code: 688595) with its "analog signal chain +MCU" series of vehicle regulation products full core debut, fully demonstrated the company's latest technological achievements and research and development strength in the field of automotive electronics。

The exhibition with "green development of scientific and technological innovation" as the event theme, gatheredByd, GAC Research Institute, Huawei Technologies, FAW-VOLKSWAGEN Foshan Co., LTD., GAC Toyota, Xopeng Automobile, Dongfeng Nissan, BAIC Guangzhou Co., LTD., Mi Automobile, Inball, Huichuan Technology, Guangzhou Denso,CelisGuangqi Honda, Dongfeng Liuqi, FAW Hongqi, Bosch and so onMore than 400 exhibitors from around the world are showcasing cutting-edge products in current automotive technology。

The Core Sea Technology pavilion is locatedB159 , showing including car gauge levelsPressure touchSoC chip CSA37F62, 32-bit general vehicle gauge microcontroller CS32F036Q, vehicle gauge USB Type-C controller CS32G020Q and a series of products have passed AEC-Q100 vehicle gauge certification。

同时，It also highlighted the newly unveiled dual-channel low-power 18/16/12-bit automotion-grade Sigma-Delta ADC with built-in high-precision reference and temperature sensors, recently unveiled at the Beijing Auto Show，And 16/12/8/4 channel 1MSPS single-ended low power 12-bit automotive grade SAR ADC and other high-precision analog signal chain vehicle regulation products。

The CS1x1x series Sigma-Delta ADCs feature a low-power design, integrated programmable gain amplifier (PGA), voltage reference and high-precision temperature sensor, and support 2V to 5.5V wide voltage supply range。Its programmable gain amplifier (PGA) has a flexible input range from ±102.Adjust 4mV to ±6.144 V for high resolution measurement of large and small signals。

In addition, the series offers both continuous conversion and single conversion modes, which automatically shut down after a single conversion, significantly reducing power consumption and making it ideal for sensor measurement applications with limited power and space。At present, this series of ADCs can be widely used in automotive BMS, ADAS, powertrain, OBC and other core components, and has achieved mass production for brand customers。

Another notable product is the CS1795x series SAR ADC, which has a sampling rate of up to 1MHz, supports 16/12/8/4 channels, and is equipped with automatic/manual mode switching。The multi-channel and high integration characteristics of this series of products make it widely used in BMS battery total voltage and insulation detection, ADAS domain control, power system monitoring and other multi-channel data acquisition scenarios, which provides strong support for the data acquisition of automotive electronic systems。

The CS1795x is particularly suitable for industrial and commercial large-scale energy storage and automotive power BMS systems。These systems operate at high voltages, so safety testing is critical。With its excellent stability and multi-channel design, the CS1795x is ideal for safety testing projects such as voltage, current, temperature and humidity, and pressure in BMS systems。At the same time, in the field of industrial automation and medical equipment, the CS1795x is also highly respected for its low power consumption and excellent ESD protection。Especially CS1795xA model, built-in high-precision benchmark, for users to save the cost of external benchmark;The CS1795xP model supports ADC expansion to 14-bit differential or 13-bit single-ended, increasing application flexibility and accuracy。

In addition to the aforementioned products，Core Sea technology exhibition presented a number of innovative products，Including vehicle gauge level pressure touch SOC chip CSA37F62, 32-bit general vehicle gauge microcontroller CS32F036Q，And car level USB Type-C controller CS32G020Q and so on，These products have been certified to AEC-Q100 vehicle regulations。

At the exhibition site, the company demonstrated a wealth of application cases。Including the CSA37F62 chip in the car steering wheel pressure touch technology demonstration, CS32G020Q chip in the car fast charge and projection screen function display, and CS32F036Q chip automotive taillight application scheme。

In particular, the unique and cool car headlight design scheme realizes the sequence of lighting and extinguishing, deducing the effect of the water lamp, which is cool and creative。These application cases fully demonstrate the excellent performance and wide application scenarios of Xinhai car gauge products, which have attracted the attention and praise of a large number of automotive engineers and industry experts。

历经More than 20 years of continuous innovation, Core Sea technology with its own "analog signal chain +MCU" dual platform technology advantages,已Successfully build a serialized, platform-based automotive electronic product ecology。At present, the company has passedISO 26262 ASIL-D functional safety management system certification, and launched a number of AEC-Q100 authoritative certified analog signal chain and MCU products, and many topTier1Manufacturers maintain close cooperation。Related products and solutions can be widely used in intelligent cockpit, human-computer interaction, vehicle PD fast charge, battery management, body control, driving safety and other key fields。

In the future, the company will grasp the opportunity of industrial change and domestic substitution of the "new four modernizations" (electrification, intelligence, networking and sharing) of automobiles, and will continue to focus on the research and development and innovation of automotive functional safety MCU products。同时，The company will further enrich the product line，Accelerate the market introduction of products including automotive SAR ADCs, Sigma-Delta ADCs, multi-string BMS AFEs, and ASIL-B and ASIL-D MCUS，Continue to improve the quality system construction，Actively expand the business of automotive electronics，To promote the safe and stable development of domestic automobile industry chain，Contribute more to the industry's technological innovation and industrial upgrading。
