NXP car entertainment navigation system

The development of the vehicle network system mainly follows the complementary cooperation with sensor technology, wireless transmission technology, massive data processing technology, and data integration technology. The future of the vehicle network system will face the system functional integration, data sea quantization, high transmission rate. The car entertainment system will become a hub for the car and the external information exchange. For example, the mobile phone and the vehicle interaction, only one smartphone can use the smart navigation, network radio, music, video, game, instant information such as mobile phone to the car to create a personalized car. Entertainment system entertainment, let the owner enjoy the happiness "cloud" driving. This program uses MTK's car entertainment navigation platform, the monolithic core board integrates most of the factors of UI, GPS, DVD, video decoding, Bluetooth, screen drive, etc., the peripheral circuit only needs to add radio, amplifier, and power supply. Can constitute a car entertainment navigation system. This article mainly introduces the solution of the SOC surrounding radio, auxiliary MCU, CAN / LIN bus and audio amplifier. Users who are interested in the core SOC program Please contact Pinjia Group. ► Product entity ► Present photo ► Forum block diagram ► Core technology advantages 1 FM / AM receives playback 2 CAN / LIN communication 3 MCU operation, LCD man machine interaction ► Scenario specifications 1 NXP TEF668X (compatible with TEF665X, TEA685X) low tunerifier, radio receiver includes the highest function set, AM / FM front end, tuning synthesizer, channel filtering, FM channel balance, FM multiple road Improve, demodulation, FM stereo decoding, weak signal processing, noise suppression and RDS, and provide interface with DARC demodulator / decoder; 2 NuC230 / 240 32bit high-performance Cortex-M0 MCU, main frequency up to 72MHz, 2 sets of CAN bus, a set of USB 2.0 full speed interface, up to 6 sets of high-speed UART serial port, 4 groups SPI interface, 2 groups I2C and USB , LIN bus, 800 kSPS high conversion speed 12-bit A / D; 3 TJA1042 high-speed CAN transceiver, maximum 1 Mbit / s, improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance, extremely low standby mode, with bus wake-up capabilities; 4 uses the TJA1021 LIN transceiver compliant with LIN 2.1 / SAE J2602, the baud rate is up to 20 kBd, high electromagnetic immunity (EMI), wake-up source identification (local or remote); Sourceful from big.
