Xinchip Technology and analog IC design company Richtek have jointly launched the “SD210” reference design aimed at smart cockpits. This reference design is based on Xinchip’s X9 series smart cockpit SoC chips and incorporates Richtek’s SoC PMIC RTQ2209 and other products, fully meeting diverse power supply requirements and aiding in the realization of high-performance, miniaturized smart cockpit systems.
Xinchip Technology and Richtek established an advanced technology development partnership in 2023, focusing on applications related to smart cockpits. Previously, the two companies developed a reference board based on Xinchip’s “X9M/E” products, equipped with Richtek’s RTQ2209, DCDC RTQ2102A, and other products, which have been adopted by several automotive manufacturers. The newly launched reference design “SD210” will continue to enhance the convenience and safety of automotive infotainment systems.
About the “SD210” Reference Design
The “SD210” is based on Xinchip’s “X9H”, “X9HP”, and “X9SP” smart cockpit SoCs, featuring Richtek’s SoC PMIC RTQ2209, Multi-Phase Step-Down Converter RTQ2134, DCDC RTQ2102A, and LDO RTQ2531A. This reference design can utilize the IC’s internal memory (MTP/OTP) for output voltage setting and timing control, providing efficient and flexible power supply according to specific circuit requirements. Pin-compatible SoCs can quickly change specifications without altering the circuit.
Richtek’s newly launched RTQ2209-QA analog IC is designed for automotive applications, featuring an advanced wettable flank QFN6x6 package, integrating 10-channel multi-configuration power management, supporting flexible I2C configuration, and boasting ultra-low static current (50uA), achieving extreme low power consumption in STR mode, significantly optimizing system performance and extending battery life. Additionally, for high-power platforms, Richtek offers high-end automotive products such as the 20A output, multi-phase 4-channel buck converter RTQ2134-QA to meet higher performance demands.
To address the diverse configuration needs of cockpit systems, Richtek provides four power configuration solutions to adapt to SoCs like X9SP/X9HP/X9H. These solutions fully leverage the highly integrated advantages of RTQ2209: simplified circuitry, space-saving, ease of operation, perfectly meeting the minimalist and efficient demands of cockpit systems.

Solution A for X9SP/X9H/X9HP Configuration 2 (see below):
This solution is suitable for systems equipped with an MCU and using DRAM LP4x, consisting of RTQ2209+RTQ2134+RTQ2102A. The MCU controls the operation of RTQ2209, RTQ2134, and RTQ2102A via GPIO and I2C interfaces. RTQ2209 powers the RTC, SAF, GPU, and LP4x, while RTQ2134 powers the AP and CPU, and RTQ2102A powers the LP4x.
-
Solution B for X9SP/X9H/X9HP Configuration 3 (see below):
This solution is suitable for systems without an MCU and using DRAM LP4, consisting of RTQ2209+RTQ2134+RTQ2531A. The X9SP/X9H/X9HP controls the operation of RTQ2209+RTQ2134 via GPIO and I2C interfaces. RTQ2209 powers the SAF, DRAM, GPU, etc., while RTQ2134 powers the AP and CPU, and RTQ2531A powers the RTC domain.
-
Solution B for X9SP/X9H/X9HP Configuration 4 (see below):
This solution is suitable for systems without an MCU and using DRAM LP4x, consisting of RTQ2209+RTQ2134+RTQ2102A+RTQ2531A. The X9SP/X9H/X9HP controls the operation of RTQ2209+RTQ2134+RTQ2102A via GPIO and I2C interfaces. RTQ2209 powers the SAF, GPU, and LP4x, while RTQ2134 powers the AP and CPU, RTQ2102A powers the LP4x, and RTQ2531A powers the RTC domain.
