RX65N and RX651 Groups are new mainstream RX microcontrollers with RXv2 core, large-capacity RAM, and enhanced security, connectivity, and HMI
High power efficiency
- Original RXv2 CPU core with maximum operating frequency of 120 MHz optimizes power efficiency (34 CoreMark/mA)
- Enables battery life of endpoint devices and so on to be maximized, and enables high performance
Extensive communication and HMI functions and encryption functions realize secure updating of device control
- The RX65N Group and the RX651 Group have products that have a code flash memory capacity of 1 MB or less, or 1.5 MB or more.
(a) Products with 1 MB or less code flash memory:
Large-capacity 256 KB RAM 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.
(b) Products with 1.5 MB or more code flash memory:
All the functions of the 1 MB or less products, plus encryption functions. 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.
Built-in added-value functions contribute greatly to product development for the IoT and enhanced HMI:
- Protection function thats prevent erroneous writing of on-chip flash memory
- Dual-bank function that enables secure and easy program updating via a network
- LCDC and 2D graphics engine enables rich, heavy-load UI (accelerates user interface processing)
- Large-capacity 640 KB on-chip RAM can also be used for graphics processing
Easy to evaluate "cryptographic function" to protect customer's important key information !
Ideal if you want to add an HMI to your project or if you want to easily evaluate color LCD and 2D drawing performance!

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.
