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)

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.
