RX65N and RX651 Groups are new mainstream RX microcontrollers with RXv2 core, large-capacity RAM, and enhanced security, connectivity, and HMI
High Power Efficiency
RXv2 core with maximum operating frequency of 120 MHz realizes high power efficiency of 34 CoreMark/mA, which enables battery life of endpoint devices, etc. to be maximized, as well as high performance.
Extensive communication functions and encryption functions realize secure updating of device control
The RX65N Group and the RX651 Group can be divided into products having a code flash memory capacity of 1 MB or less, and or 1.5 MB or more. The products with 1 MB or less code flash memory is equipped with a large-capacity RAM of 256 KB for carrying out high-speed communication processing that is required for various communication interfaces such as Ethernet, USB, CAN, SD host/slave interface, and quad SPI. The products with 1.5 MB or more code flash memory have even more enhanced encryption functionality. Trusted secure IP protects encryption keys by controlling access. By combining this with a rich variety of communication functions high root-of-trust levels are achieved. Furthermore, protect and dual-bank functions that prevent erroneous writing of on-chip flash memory enable secure and easy program updating via a network. In addition, the large on-chip RAM of 640 KB allows high-speed processing of heavy loads, enabling rich user interfaces using the LCDC and 2D graphics engine.
Reduce development time
The RX65N and RX651 Groups are highly compatible among the same series both in functional scalability and pin assignments. In addition, driver/middleware (FIT support), sample code-generation tools (code generators), and evaluation boards (starter kit and Envision Kit) are available, to allow reuse of most developed hardware/software resources. Partner tools that make it easy to build the kind of user interfaces (UI) that are essential for HMI are also available. All these enable seamless and scalable product development from small to large-scale applications easily and in a short time.
We offer the following solutions for reference for the RX651 Group and the RX65N Group to help you embed encryption technologies and HMI (human-machine interface) essential for IoT into your system immediately.

Hardware Design Support
IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.
BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
