Renesas R9A06G064MGBG#BC0

Overview

R9A06G064MGBG from Renesas Electronics is a single-chip industrial Ethernet communications LSI integrating an Arm® Cortex®-M4 core (100 MHz), dual-port 10/100/1000BASE-T PHY, Gigabit Ethernet MAC with integrated 2-port switch, and hardware real-time OS accelerator. It delivers low-jitter, deterministic network control for CC-Link IE Field/TSN, PROFINET RT, EtherNet/IP, and Modbus TCP in factory automation gateways and remote I/O units.

For engineers reviewing the R9A06G064MGBG datasheet, R9A06G064MGBG pinout, R9A06G064MGBG application, or R9A06G064MGBG equivalent, this page provides verified package mapping (484-ball PBGA, 23 mm × 23 mm), confirmed Ethernet protocol stack support, validated memory subsystem specs (768 KB IRAM + 512 KB DRAM, both with ECC), and functional alternatives for industrial Ethernet node design.

Technical Context

The R9A06G064MGBG implements a tightly coupled architecture with AXI (64-bit @ 125 MHz) and AHB-Lite (32-bit @ 100 MHz) buses, dedicated DMA channels for network processing, and on-chip 128 KB Network RAM with ECC. Its integrated 2-port Ethernet switch supports cut-through transfer, IEEE 1588 timestamping, and Device Level Ring (DLR) for ring topology resilience.

It integrates two CAN controllers (ISO 11898, up to 1 Mbps), dual UARTs with FIFOs, dual I²C interfaces, and a serial flash ROM controller supporting Quad I/O boot. The built-in 2.5 V regulator powers the PHY independently from the 3.3 V system supply, ensuring signal integrity across temperature (−40°C to +125°C junction).

FAQ

What is the maximum operating junction temperature for the R9A06G064MGBG?

The R9A06G064MGBG has a specified maximum junction temperature of +125°C, with ambient operating range of −40°C to +85°C. This rating is validated across all functional blocks including the Arm Cortex-M4 core, dual Ethernet PHYs, and integrated switch fabric, enabling deployment in high-temperature cabinet environments typical of industrial motor control systems. Thermal derating guidelines are provided in Section 5.2 of the R18DS0031EJ0100 datasheet.

Does the R9A06G064MGBG support IEEE 1588 Precision Time Protocol (PTP) in hardware?

Yes, the R9A06G064MGBG implements full IEEE 1588 v2 hardware timestamping within its integrated Gigabit Ethernet MAC and switch. It supports one-step and two-step PTP modes, hardware-based timestamp insertion on transmit and capture on receive, and synchronization of both Ethernet ports to a common time base. This capability is essential for CC-Link IE TSN Class A/B compliance and deterministic motion control applications requiring sub-100 ns time accuracy.

Can the R9A06G064MGBG operate without an external crystal oscillator?

No, the R9A06G064MGBG requires a 25 MHz fundamental-mode crystal connected to XT1/XT2 pins for primary clock generation. Its internal PLL synthesizes all system clocks (100 MHz CPU, 125 MHz AXI, 97.2 MHz CCI_CLK2) from this reference. While the device includes a built-in 2.5 V PHY regulator and voltage supervisors, the crystal is mandatory - no internal RC oscillator is provided for Ethernet timing-critical functions.

How many CAN interfaces does the R9A06G064MGBG integrate, and what protocol versions do they support?

The R9A06G064MGBG integrates two independent CAN controllers compliant with ISO 11898-1:2015, supporting both standard (11-bit ID) and extended (29-bit ID) frames at bit rates up to 1 Mbps. These controllers are fully compatible with CAN FD physical layer transceivers and support programmable sample points, automatic retransmission, and error confinement - enabling robust fieldbus connectivity for hybrid industrial networks alongside Ethernet.

Is the R9A06G064MGBG pin-compatible with earlier R-IN32M4 series devices?

Yes, the R9A06G064MGBG in the 23 mm PBGA package maintains pin compatibility with the R-IN32M4-CL2, allowing direct PCB replacement in existing designs. Key signals including Ethernet PHY interfaces (P0/P1 differential pairs), MDIO/MDC, reset, and power domains retain identical pin locations. However, new functions like CCI_CLK2_097M and HIFSYNC appear on previously unused balls, preserving backward compatibility while enabling enhanced timing features.
