To a larger point, it can involve ADAS technology, machine vision, radar, sensor microcontrollers, and entertainment systems. ST can bring all the key technologies together and provide them to customers as a solution.
In the low-end and mid-end cars, the entertainment system has become an important breakthrough for automakers to create differentiation. The functions that were previously available on high-end cars have now slowly dropped into mid- and low-end cars, so the cost control of the entertainment system has become more and more sensitive.
The above picture is the application block diagram of the car entertainment system shown by ST. We can see that it is mainly divided into two categories of applications. Entertainment requires the participation of terrestrial radio receivers, infotainment processors and advanced audio devices; in the case of interconnection, satellite broadcast receivers, positioning systems, in-vehicle information services and shop floor communication systems are required. ST's products in the entertainment sector can be divided into four categories: satellite positioning, processors, tuners and audio amplifiers. Among them, the Teseo series satellite signal receiving chip for satellite positioning can receive the information of the Beidou navigation satellite system to achieve precise positioning of the vehicle. The processor product line includes two product lines, Accordo and Telemaco, which are the most cost-effective mid-range mid-range infotainment and information service system-level processors. The tuner Elite product line is used for receiving and tuning functions in digital radios for clear sound quality. The TDA75610 series of audio amplifiers are specifically designed for car audio applications, with high energy efficiency, comprehensive protection and reasonable price, which can achieve OEM-quality sound quality. In the connected field shown in the figure below, ST believes that there will be a market opportunity of $700 million by 2020.
The Accordo5 released at the conference is ST's latest in-vehicle mid-range entertainment processor, which can help customers realize low-cost and high-performance entertainment system design in low-end and mid-end cars.
Accordo5: mobile screen + information service + LCD meter
Accordo5 is another dedicated chip for car entertainment systems after Accordo2. The biggest upgrade compared to Accordo2 is the addition of Wi-Fi module and DDR3 support, as well as the support of the CAN FD protocol. Accordo5 is a car-specific entertainment chip that combines the functions of mobile phone screen display, information service and LCD instrument.

There are currently three products in the Accordo5 product family, STA1275, STA1285 and STA1295, which integrate the ARM Cortex-A7 architecture inside the chip. Among them, STA1275 and STA1285 are integrated with single-core Cortex-A7, which can support external 16-bit high-performance DDR3 memory. The highest performance STA1295 adopts dual-core A7 architecture design, which can realize 16-bit or 32-bit high-performance DDR3 memory. support. Although it is mainly in the mid-end car market, the Accordo5 500MHz 3D graphics processor core is ahead of its competitors, supporting 1080p 2D and 3D graphics decoding, supporting up to four layer blending and video overlay functions. The provider of this GPU is VeriSilicon, an industry leading GPU IP provider. In addition, the display controller built into Accordo supports FullHD's TFT-LCD touch screen and supports six stereo analog channel support.
In addition to powerful audio and video capabilities, security is a particular priority in the Accordo5 design. It is reported that the Corcor-M3 or M7 microcontroller is built in Accordo5, which runs the Autosar operating system independently, and manages the security of the CAN interface between the car digital instrument panel and the car's main network.
