Lately, the proliferation of sensible cockpits and ADAS in autos has elevated the demand for automotive electronics and elements. The efficiency of PMICs and SerDes ICs, that are on the coronary heart of digital techniques in autos, has a direct affect on the soundness and effectivity of your entire system. On this context, ROHM PMICs and SerDes ICs obtain a excessive stage of integration in energy provide blocks whereas supporting elevated stability throughout high-speed information transmission.
ROHM and SemiDrive have been exchanging applied sciences since 2019, significantly within the improvement of functions for car cockpits. In 2022, the 2 firms entered right into a strategic partnership for the event of superior applied sciences within the automotive sector. This resulted in ROHM elements resembling PMICs and SerDes ICs being built-in into the reference board for SemiDrive’s X9H In-Automobile SoC. The reference board has since been adopted by quite a lot of automakers to offer superior performance for cockpits and different car functions.
This time, ROHM and SemiDrive have collaborated on the event of the REF66004 reference design that includes the vehicle-mounted SoCs X9M and X9E. As such, the REF66004 is anticipated to additional broaden utility line-up, together with in well-liked mass-market fashions. Along with the SerDes IC used within the X9H reference board, ROHM additionally offers the BD96801Q12-C SoC PMIC and BD9SA01F80-C buck converter IC for driving the SoC, in addition to the BD39031MUF-C general-purpose PMIC for ADAS that provides energy to the SerDes IC. This answer helps operation of as much as three show projections and 4 ADAS cameras (Encompass-view digicam). Going ahead, ROHM will proceed to develop merchandise for automotive infotainment techniques that contribute to bettering automotive security and luxury.
Zhang Qiang, Chairman, Nanjing SemiDrive Know-how Ltd.:
“As autos turn into more and more sensible, so too does the demand for automotive electronics and elements. SemiDrive is targeted on offering core elements resembling automotive SoCs and controllers for next-generation automotive E/E (Electrical/Digital) architectures. Partnering with ROHM, which gives a wealthy portfolio of semiconductors for ADAS and cockpits, will tremendously contribute to reaching next-generation cockpit options. Specifically, ROHM SerDes ICs and PMICs which leverage authentic analog expertise are key elements in our reference design. We sit up for persevering with our collaboration with ROHM to offer revolutionary options in a variety of automotive fields.”
Tetsuo Tateishi, Member of the Board, Senior Company Officer, accountable for Analysis & Growth, IT, Authorized & Mental Property and LSI Enterprise, ROHM Co., Ltd.
“We’re happy to have developed this reference design in collaboration with SemiDrive, an organization with intensive expertise in automotive SoCs. As ADAS evolves and cockpits turn into extra multifunctional, the function of automotive analog semiconductors resembling SerDes ICs and PMICs is changing into more and more vital. On the similar time, the brand new PMIC supplied by ROHM for SoCs represents a novel idea in energy ICs that may flexibly adapt to next-generation automotive energy system configurations. Going ahead, we’ll proceed to deepen our partnership with SemiDrive to extend our understanding of next-generation cockpits and speed up the event of a variety of merchandise, contributing to additional evolution within the automotive sector.”
REF66004 Reference Design Incorporating X9M, X9E, and ROHM Merchandise
This reference design combines SemiDrive’s X9M and X9E SoCs for sensible cockpits with ROHM PMICs for SoCs and ADAS, SerDes ICs (for show/digicam), LVDS splitter IC, and LED driver IC for car shows. It’s obtainable on ROHM’s web site. The design gives a cockpit answer able to driving as much as three display screen projections and 4 cameras. As well as, ROHM’s new PMICs for SoC allow arbitrary output voltage setting and sequence management by way of inside reminiscence (One Time Programmable Reminiscence), permitting versatile, excessive effectivity energy provides to be achieved which might be tailor-made to circuit necessities.
A reference board based mostly on this design can be obtainable individually on request, able to operating a number of working techniques (OS) on a single SoC benefiting from SemiDrive’s distinctive {hardware} virtualization capabilities. On the similar time, a {hardware} safety administration module allows the transmission of instructions from the working system to the SoC and GPU. By swapping totally different SemiDrive SoCs with appropriate pinouts, utility specs could be modified shortly and with out circuit adjustments.

Terminology
SoC (System-on-a-Chip)
A kind of built-in circuit that comes with a CPU (Central Processing Unit), reminiscence, interface, and different parts on a single substrate. Extensively utilized in automotive, shopper, and industrial functions resulting from its excessive processing capability, energy effectivity, and area financial savings.
PMIC (Energy Administration IC)
An IC that incorporates a number of energy provide techniques and capabilities for energy administration and sequence management on a single chip. It’s changing into extra commonplace in functions with a number of energy provide techniques in each the automotive and shopper sectors by considerably decreasing area and improvement load vs typical circuit configurations utilizing particular person elements (i.e. DC-DC Converter IC, LDO, discretes).
SerDes IC
A generic time period for ICs sometimes utilized in pairs to transform communication strategies for the aim of high-speed information transmission. The serializer converts information right into a kind that may be simply transmitted at excessive pace (parallel to serial bus) whereas the deserializer converts the transmitted information again to its authentic format (serial to parallel bus).
