Renesas Electronics announced the availability of the new series of microcontrollers RX71M, product of the well known family of RX microcontrollers 32 bit. RX71M was developed for industrial applications and doubles the operating frequency from the current 120 MHz family RX64M to well 240 MHz.
The greater complexity of the communication applications lead developers to adopt tools and third-party libraries for the purpose of reducing the weight of the development hardware and, and, software. A typical example is the transition to the IoT devices where the complexity is such that often the 'use of software packages, operating systems and drivers to ensure that the suppliers' update protocols and interoperability of systems. Are, on the one hand, the advantages of this approach are obvious from 'another opening this creates problems of information security and protection of proprietary software that represents the Know How of' company. Consequently, it becomes increasingly important to adopt development processes, instruments and arrangements which provide for the protection of proprietary software.
Industrial applications require performance to support processes in real time so that the maximum execution time of a given function as well as the response time for a given event are always insured. When the CPU of a micorocontrollore works at a frequency higher than that to which he works FLASH memory becomes necessary to use a static RAM memory (SRAM) dedicated and high performance in order to be certain that the execution time provided are respected, in this case it 's use of memory-based architectures CACHE can not ensure the required performance due to their inherent uncertainty in response time.
To meet these demands Renesas has developed the group consisting of microcontrollers RX71M 112 devices with packages that vary between 100 pin e i 177 pin and with FLASH board that varies between 2 MB e i 4 MB.
