Would you like to address the challenges of networkconnected equipment by using 32-bit RX66N MCUs?

时间： 2021-12-02 来源：Renesas

Networking equipment such as smart meter and HVAC controller requires real-time performance that achieves both operation of complicated system and network communication. In addition, it requires constant firmware (FW) updates for continuous stable operation.

It means that the microcontroller for main control of the equipment should have those performance and functionality as well. Wouldn’t it be nice to have a MCU meeting those requirements with a single chip and an evaluation kit for easy evaluation?

This time, RENESAS will introduce the 32-bit MCU RX66N that can meet those requirements and the Target board for RX66N, an evaluation kit that enables easy and quick evaluation and PoC (Proof of Concept).

The secret key of RX66N outstanding real-time performance is its CPU and flash memory. The Renesas' proprietary RXv3 CPU core realizes outstanding performance with a CoreMark scores of 707 operating at 120MHz, and the 4MB flash memory can be read with zero wait states from the RX CPU, still keeping up the processing speed while executing the code stored in the flash memory.

In addition, the 4MB flash memory is capable of dual-bank configuration, which benefits firmware update and makes it possible to download the updated firmware to the flash memory during system operation by utilizing the background operation (BGO) function.

Furthermore, Renesas provides the Target Board for RX66N for easy and quick evaluation of the features mentioned above. It comes build-in with an emulator circuit, making it possible to evaluate RX66N outstanding real-time performance just by connecting to a PC with the USB cable. Also, when connecting Wi-Fi modules to the on-board Pmod connector, you can build the RTOS-based cloud connectivity and the system with firmware update via the network. Using the cloud solutions for the RX family, middleware for FW update, and sample program, you can easily and quickly perform the evaluation and make PoC.
