Engage in automotive electronics, how to choose a high-performance processor

Today, NXP mainly for the automotive, consumer electronics and other specially designed based on an ARM ® Cortex ® A7 cores I.MX 6ULL series of high performance, high reliability, low-power applications processor, and the highest frequency up to 900MHz, The power management module and 128 KB L2 cache are also integrated internally; in addition, the i.MX6ULL integration is optimized and cost-competitive, meeting the requirements of IoT gateways, endpoints and consumer electronics.

With the continuous updating of today's technology, some consumer electronics such as automobiles are getting higher and higher, and the performance is more stable and reliable. Therefore, it is welcoming opportunities in the field of automotive consumer electronics. Therefore, Xiaobian recommends high performance and low power consumption. The i.MX6ULL family of processors, which integrates a PMU to reduce the complexity of the external Power Supply and simplify power-up sequencing. The processor also offers a variety of memory interfaces (including 16bit LPDDR2, DDR3, DDR3L, NAND Flash, NOR Flash, emmc) and QSPI, I2C, CAN, UART, USB, Ethernet and other protocol interfaces.

High performance and low power consumption

The i.MX6ULL series processor controls the main frequency and performance of the MPU through the internal PMU to control and manage the supply voltage of the internal modules of the SOC. The power supply range is as low as 1.5v, and I2S/SAI with three 1.4Mbps transmission speeds. /AC97, 8-channel 5.0Mbps transmission speed serial port (UART), 4-channel 52Mbps transmission speed eCSPI, 4-channel 400kbps transmission speed I2C, 2-channel 100Mbps transmission speed Ethernet (Ethernet), 1-channel enhanced serial audio interface (ESAI), 1 channel digital audio interface (SPDIF), 2 12-bit analog-to-digital conversion interface, 1 channel supports 8/10/12/16-bit camera interface; above can see i.MX6ULL series processor The function is not only powerful, but also low power consumption, fully meeting the needs of today's consumer electronics and automotive electronics. The following shows the operating voltage range of the SOC:

Operating Ranges Diagram

The i.MX6ULL series processor has ESD (electrostatic protection) inside, of which the voltage of human discharge protection (HBM) can reach 2Kv, and the voltage of device discharge protection (CDM) can reach 500v, which can be from -40 degrees Celsius to 150 degrees Celsius. It works normally in harsh environments and meets application control circuits in industrial complex noise environments.

The i.MX6ULL series processor runs the Linux operating system, so we write technical documentation related to the driver and application demo routines, including the compilation of the linux system image and the technical notes for driver compilation and demo routines. The technical documentation greatly reduces the development difficulty for users; when users encounter problems, they can refer to technical notes or documents for development and solution, or contact ZLG for more comprehensive technical support.

Compared with the core board of ARM9 series, i.MX6ULL has lower power consumption and more powerful performance. It supports more peripheral interfaces and supports up to 8 channels of UART, 2 channels of Ethernet, 2 channels of CAN and other industrial bus interfaces. The core board has an industrial grade version, and the severe temperature level test ensures that the core board runs stably in the -40 ° C ~ +100 ° C environment; in addition, it can also be used for in-vehicle information processing, home energy management systems, IoT gateways, etc. Develop applications.
