Sun Mingle, CTO of Xinchi Technology, said: "With the rapid development of automotive intelligence, the requirements for automotive electronics and components are also increasing. X9SP is the core flagship product of Xinchi X9 series high-performance cabin SoC, designed for intelligent cabin and cross domain integration scenarios, with high performance and reliability, especially suitable for cabin parking integrated solutions. The newly developed reference design combines ROHM's PMIC with X9SP to improve the overall system stability and energy efficiency. We look forward to continuing our collaboration with ROHM to provide various innovative in car solutions in the future.

We are delighted to collaborate with Xinchi Technology, a leading company in the automotive SoC field, to develop a new reference design, "said Tetsuo Kishi, Senior Executive Officer of ROHM. The intelligent cockpit integrating various functions such as information entertainment and ADAS monitoring is accelerating its popularity, especially in the next generation of electric vehicles, where the role of on-board analog semiconductor products such as PMIC is becoming increasingly important. The PMIC provided by ROHM for SoC this time is a power IC that can be flexibly applied to the new generation of car power supplies and meet functional safety requirements. In the future, by continuing to deepen communication and cooperation with Xinchi Technology, ROHM will accelerate the development of products that support the multifunctional development of the next generation of intelligent cockpits, and contribute to the further development of the automotive industry. ”

<Background>

In recent years, the popularity of intelligent cockpits has accelerated the adoption of large displays, in addition to various functions such as instrument clusters and information entertainment systems. At the same time, the processing power required for in vehicle SoCs is also increasing, thus requiring power ICs such as PMICs as core components to undertake power supply while supporting current and efficient operation.

ROHM provides PMIC for SoC, which not only has high stability and efficiency, but also allows for arbitrary output voltage setting and sequence control through internal memory (OTP). By minimizing circuit changes, power systems can be built for various vehicle models and models, contributing to reducing development time for automotive manufacturers.

Regarding the reference design "REF68003" equipped with "X9SP" and ROHM products

The "REF68003" is equipped with Xinchi Technology's intelligent cockpit SoC "X9SP" and ROHM's SoC PMIC. At present, the reference design has been validated by Xinchi Technology. By utilizing this reference design, an intelligent cockpit that achieves safety level ASIL-B can be realized. In addition, the SoC provided by ROHM uses PMIC, which can use internal memory (OTP) for arbitrary output voltage setting and timing control, thus enabling efficient and flexible power supply according to specific circuit requirements.

This reference design utilizes Xinchi Technology's proprietary hardware virtualization support function, which supports running multiple operating systems (OSs) on a single SoC. Meanwhile, by utilizing the hardware security management module, commands from the OS can also be passed to the SoC and GPU. In addition, by replacing with other pin compatible SoCs from Xinchi Technology, specifications can be quickly changed without changing the circuit.

*1) SoC (System-On-a-Chip: System on Chip)

An integrated circuit that incorporates a CPU (central processing unit), memory, interfaces, and other components. In order to achieve high processing capacity, power efficiency, and space reduction, it is widely used in the fields of vehicle mounted equipment, household equipment, and industrial equipment.

*2) PMIC (Power Management IC)

An IC that contains multiple power systems and integrates power management and timing control functions on a single chip. Compared with circuit structures that use DC-DC converter ICs, LDOs, and discrete components alone, it can significantly save space and shorten development cycles. Therefore, in recent years, it has become a commonly used component in applications with multiple power systems, whether in the field of automotive devices or consumer electronics.

*3） SerDes IC

The general term for two ICs used in pairs for high-speed data transmission and for communication mode conversion. A deserializer is used to convert data into a format that is easy to transmit at high speeds (converting parallel data into serial data), while a deserializer is used to convert transmitted data into its original format (converting serial data into parallel data).

*4） ISO 26262、ASIL（Automotive Safety Integrity Level）

ISO 26262 is an international standard related to functional safety of automotive electronic and electrical systems, officially promulgated and implemented in November 2011. It is a standardized development process aimed at achieving 'functional safety'. It is necessary to calculate the fault risk in the on-board electronic control and embed the mechanism to reduce its risk as one of the functions in the system in advance. This standard covers from the vehicle concept stage to the system ECU、 The entire lifecycle of vehicle development, including embedded software, device development, production, maintenance, and scrapping stages. ASIL is a risk classification system defined in ISO 26262, which is divided into four levels. The higher the risk level, the higher the requirements for functional safety.
