Industry-Leading 4MB On-Chip Flash Memory and 120 MHz Read Operation for Enhanced Real-Time Performance in Industrial Applications...
Renesas Electronics Corporation announced the RX72N Group and RX66N Group of 32-bit microcontrollers (MCUs), new additions to the RX Family that combines equipment control and networking function on a single chip. Built around the Renesas proprietary RXv3 CPU core, the RX72N features a maximum operating frequency of 240 megahertz (MHz) and two Ethernet channels, and the RX66N features a maximum operating frequency of 120 MHz and one Ethernet channel.
In the industrial equipment market, performance and functionality improvements lead to larger program code sizes. As a result, storage capacity and read speed play key roles in determining real-time performance. The new RX72N and RX66N devices offer up to 4 megabytes (MB) of on-chip flash memory that perform read operations at a frequency of 120 MHz, as well as 1 MB of on-chip SRAM. This ample on-chip memory eliminates the need for external memory, which has slower read speeds, and makes it possible to extract the full performance capacity of the CPU. In addition, larger memory capacity enables high-resolution graphics support, such as WVGA, on a single chip, which was not possible on earlier general-purpose MCUs.
With this combination, the MCUs can implement single-chip equipment control and networking function, enhancing the real-time performance of applications such as industrial robots, general-purpose inverters, programmable logic controllers (PLCs), and remote I/O devices. They also make it possible to improve the exterior design and operability of a wide range of industrial automation equipment.
“The new products extend our portfolio of MCU products that combine equipment control and networking function on a single chip, joining the already available RX72M with EtherCAT support, and the mainstream RX65N and RX651 models,” said Sakae Ito, Vice President of IoT Platform Business Division at Renesas. “The RX Family provides a high level of hardware and software inter-compatibility, making it easy for customers to build a development platform that scales from low-end to high-end products.”
