These trends led to the engine and transmission to achieve a more accurate control of power system requirements and for functional and cost-optimized MCU product development has become a major theme. Renesas Technology Corp. is currently in production powertrain control applications for the SH7050 Series and M32R family 32-bit Flash MCU, and these products have been widely used. Product development process at an early stage technology and experience accumulated on the basis, in order to meet the demand for higher performance, integration of Renesas Technology Corp. began developing the high-speed operation and large Flash memory capacity, using the SH-2A CPU core in order to advanced 90nm process node to achieve outstanding performance and real-time control Flash memory MCU. The first product - SH72544R - is the result of these efforts, was released in July 2008, and can provide fast action and full 2.5Mb speed Flash memory. Now launched a new SH72531 MCU, it can provide some properties of SH72544R. SH72531 using high-performance SH-2A CPU core, which can be a variety of technology companies in the Renesas SuperH * 3 series of 32-bit RISC MCU / MPU to provide excellent real-time performance. SH-2A superscalar Harvard architecture used, to simultaneously execute two instructions. Thus, it can be in the operating frequency of 120MHz to achieve 240MIPS processing performance.
When necessary redundancy: multiple WAN lines Another advantage is to provide redundancy. A common situation is that in some areas by operators will send the user ADSL fiber optic lines, then you can with ADSL for fiber redundancy, in the former fails to withstand the first to use ADSL. Some users will want to use different operators of the line, this line or in the engine room operator A problem occurs, you can substitute B line operators. For some industries, such as the media industry, need to keep access to the Internet, this feature is particularly important. When insufficient bandwidth AD: general business to multi-use ADSL, according to statistics of SMEs is the largest increase in broadband subscribers using ADSL Internet access. However, some areas appear small relative bandwidth of ADSL, such 64K/64K line, is clearly inadequate for enterprise applications, but also apply for ADSL to fiber Degui off than a few, in this case, the use of a number of multi-WAN routers together ADSL lines, after all, a viable and cost-effective way.
