R-IN32M4-CL3
Compared to conventional technologies, Ethernet communications in the industrial field are strongly required to have
high-performance functions such as higher speed real-time response. These requirements are not necessarily realized by
traditional methods such as making the Ethernet processing itself hardware or using a dedicated CPU for high-speed
network processing.
The R-IN32M4-CL3 Ethernet communications LSI from Renesas Electronics has the following functions to realize
“higher speed real-time response” and “high-accuracy communications control (low jitter communications)” which are
important for Ethernet communications in the factory automation field.
■ CPU
• Integrated Arm® Cortex®-M4 core
• Integrated hardware real-time OS accelerator (HW-RTOS)
■ Peripheral
• Timers, WDT, I2C, UART, CSI, CAN, and general-purpose I/O ports (GPIO)
• Serial flash memory controller
■ External memory/external MCU (microcontroller) interface
• External memory connection mode: 16- or 32-bit bus connection to external devices such as SRAM
• External MCU connection mode: 16- or 32-bit bus connection to host MCU
■ Ethernet
• Integrated Gigabit Ethernet MAC
• Integrated switching hub with cut-through transfer, IEEE 1588 timer, and Device Level Ring (DLR) functions
• Integrated 2-port 10/100/1000BASE-PHY
• Dedicated DMA controller and buffer for the network processor
■ Supported industrial Ethernet protocol
• CC-Link IE Field intelligent device station and remote device station
• CC-Link IE TSN remote station (authentication Classes: A and B)
• PROFINET RT
• EtherNet/IP
• Modbus TCP
■ Target application
• Remote I/O
• Inverter and servo drive
• Industrial Ethernet communication unit
■ Others
• Pin assignment considering a replacement from R-IN32M4-CL2
• Integrated 2.5 V regulator for PHY
