High-performance 32-bit microcontroller for industrial network solutions

The RX72M Group microcontrollers are high performance products operating at 240 MHz with RX's 3rd generation CPU core "RXv3 core". Double-precision floating-point processing instructions can significantly improve processing power. It incorporates an EtherCAT® slave controller and realizes a system configuration that requires a dedicated controller on a single chip, contributing to a reduction in the number of parts and space saving.

Key Features

  • RXv3 Core 240 MHz operation (5.82 CoreMark/MHz)
  • 2.7 to 3.6 V operation
  • Operating Temperature: -40 to 85 °C/ -40 to 105 °C
  • Large-capacity memory: Code flash up to 4 MB, SRAM 1 MB
  • Dual Bank Function
  • Line up max. 224-pin LFBGA package product
  • Built-in EtherCAT® slave controller
  • Support small TFT LCD display (to WVGA)
  • Trusted Secure IP (Optional)

Software Design Support

Title Description
e² studio This integrated development environment (IDE) is based on the popular combination of the open-source Eclipse IDE and its CDT plug-in that enables C/C++ language development.
CS+ This integrated development environment (IDE) can be used for coding, assembly, compiling, and simulation. CS+ is also included with starter kits.
E2 emulator Lite This entry-level on-chip debugging emulator provides functionality equivalent to that of the E1 emulator at a low price.
E2 emulator This on-chip debugging emulator has advanced features that improve the efficiency of development. In addition to the basic functions from debugging to flash programming, this emulator supports hot plug-in and external triggers as standard items. This emulator also helps to reduce development time by downloading at high speeds (compared to the E1 emulator) and the ability to work in combination with various solutions such as the tuning of current drawn by systems under development.
E20 emulator This on-chip debugging emulator has enhanced debugging facilities such as large-capacity tracing and real-time RAM monitoring when used in combination with RX600 and RX700 MCUs (this emulator provides debugging functionality equivalent to that of the E1 emulator for other MCUs).
E1 emulator This on-chip debugging emulator is a standard model which provides basic debugging functions (production is to be discontinued at the end of December 2019).

e2 studio Renesas eclipse embedded studio, known as e² studio, is a complete development and debug environment based on the popular Eclipse CDT project.
E1 A standard Renesas on-chip debugging emulator that enables users to carry out ample debugging for real development at low cost. (Also included with starter kits.)
E2 Lite
The E2 emulator Lite is also available as a flash memory programmer with flash programming software (Renesas Flash Programmer).
Renesas Starter Kit+ for RX72M All the development tools you need for MCU evaluation and getting started. Also recommended for training.


Hardware Design Support

Title Description
IBIS/BSDL IBIS standard simulation data is required for high-speed board design and can be used to run simulations to examine and troubleshoot issues such as waveform reflection, ringing, and so on, before producing the actual board.
BSDL is a data input format supported by most IEEE 1149.1 (JTAG)-compliant tools. The automatic test pattern generation (ATPG) and automatic test equipment functions of these tools facilitate testing.
Resonator Information Please search for your resonator on its manufacturer's site linked below. If you require optimal oscillation circuit constants for your particular system, please ask the manufacturer of the oscillator.
