Recently, Manager Dai Qihong of the Renesas Electronics China Industrial Solution Center introduced the latest MPU chip RZ/N1 from Renesas Electronics. The product mainly focuses on industrial automation solutions. Through the introduction of this product, we can also see that How is Sa Electronics laid out in the industrial field.
At present, the industrial field occupies an important position in Renesas Electronics, and its output value accounts for nearly 30% of Renesas Electronics' total output value. After the automobile, Renesas Electronics is the second most important market-oriented market.
“The digital industrial market has some key requirements. For technology, it needs to include improving machine efficiency, enhancing real-time analysis and process optimization to achieve intelligent and agile production processes.†Dai Qihong said: “For us, not only provide Meeting the technical requirements of the digital industrial market requires meeting both IT and OT requirements, taking into account security and connectivity, and providing more solutions."

Renesas Electronics currently offers technologies and solutions
Dai Qihong said that in the face of industrial IoT and industrial 4.0 markets, Renesas Electronics currently offers solutions including industrial network solutions, BLDC motors and servo motion control, hardware real-time OS, DRP processors, advanced Ethernet switches and encryption solutions. Solutions, security software packages, low-power sensing solutions, and AI artificial intelligence solutions cover a wide range of industrial solutions.
In terms of products, Renesas Electronics is involved in both control and field products.
As shown in the figure, the layout of Renesas Electronics in the industrial market can support applications at all levels.
Industrial Grade Controller RZ/N1
RZ/N1 is a product launched by Renesas Electronics in November 2017. It is mainly used in programmable controllers (PLCs) and gateways, remote I/O and other applications.
Dai Qihong said that RZ/N1 has four major characteristics.
The first is to support multi-protocol industrial networks, including EtherCAT, PROFINET, OPC UA, Canopen and EtherNet/IP.
The second is intelligent control. The Cortex-A7 and Cortex-M3 heterogeneous core architectures in the chip enable higher-performance intelligent control, support for multiple memories including DDR2/3, NAND, QSPI Flash, and support complex applications.
The third point is that it supports Gigabit Ethernet with up to 5 ports on the industrial IoT gateway, which satisfies the network connection between IT and OT, and also supports TSN time-sensitive networks.
The fourth point is to focus on security and prevent cyber attacks. The mounted memory has an on-chip ECC check. Support for unique IDs prevents programs from being stolen. Supports redundant protocols required by industrial switches, such as HSR/PRP/MRP.
The positioning of the RZ family is based on the arm's MPU, with performance ranging from 300MHz to 1.5GHz, which is mainly used in the integration of control and IT technology in the industrial market.
At present, the RZ family consists of four major blocks, namely display, industrial internet, motor control and human-machine interface. RZ/N1 is the first industrial Internet product of Renesas Electronics.
Dai Qihong said that RZ/N1 is a third-generation product based on the R-IN engine platform. The first generation is R-IN32 and the second generation is RZ/T1.
The R-IN engine platform is mainly responsible for accelerating protocol processing. It contains 32-bit CPU and hardware RTOS. In addition, there is an Ethernet accelerator to achieve higher performance real-time network communication. Dai Qihong said that the R-IN interrupt response is relatively normal. Time can be reduced by a factor of six, multitasking can be tripled, and with very little jitter.
As shown in the figure, the measured results show that the ordinary MCU is running at full capacity under the network transmission load of 50MHz 50Mbps. The products using the R-IN engine are not only higher in frequency, but also easy to achieve close to 100 megabits, CPU load is only 20% to 30%.
RZ/N1 separates the application part from the real-time part on the chip architecture, integrates the protocol stack at the general operating system abstraction level, and realizes seamless communication of the on-chip CPU through shared memory and interrupt request to meet the latest IT/ OT industrial applications have dual needs for real-time and high performance.
The platform strategy adopted by Renesas Electronics' RZ/N1 itself provides hardware and some software, and some industrial Ethernet protocols are provided through third-party partners. Since the protocol is simplified by the operating system abstraction layer, if the customer wants to call the real-time communication protocol, the R-IN engine can be directly called, and no secondary development is required, and the client only needs to pay attention to the application layer.
RZ/N1 specific performance indicators and development
Currently based on RZ/N1, Renesas Electronics offers a total of 3 series and 5 packages, which correspond to different specific applications.
To better promote the product, Renesas Electronics offers a solution suite that includes development boards, drivers and sample support packages and code that customers can evaluate directly. For the development environment, RZ/N1 also supports different third-party development tools and OS.
"RZ/N1 meets the needs of IT and OT connections through multi-protocol security and high performance. It can help customers realize next-generation PLC and remote I/O market, and also have infrastructure and building automation. Strong competitiveness.†Dai Qihong concluded.
