Built on the Renesas RXv3 CPU core, the RX72N has an operating frequency of up to 240 MHz and two Ethernet channels, and the RX66N has an operating frequency of up to 120 MHz and one Ethernet channel.
Storage capacity and read speed play a large role in determining real-time performance for the industrial automation market due to the larger program code sizes found there. The two new MCU families have up to 4 MByte of on-chip flash that can perform read operations at up to 120 MHz, as well as 1 MByte SRAM. The ample on-chip memory eliminates the need for external memory, which has slower read speeds. Larger memory capacity also allows high-resolution graphics support, such as WVGA, on a single chip.
Renesas has also launched the RX72N Envision Kit to simplify experimentation with an array of functions, including:
- Network (wired: Ethernet, wireless: Wi-Fi/Bluetooth LE combo module on-board)
- Security (Trusted Secure IP and flash memory protection function incorporated into RX72N)
- HMI (4.3-inch WQVGA TFT LCD, audio IC, MEMS microphone on-board)
- Connectivity (USB 2.0 Full Speed Host, SD host interface, QSPI)
