Renesas R9A06G032VGBG#AC1

Overview

R9A06G032VGBG#AC1 from Renesas is a dual-core Arm Cortex-A7 (500 MHz) + Cortex-M3 (125 MHz) industrial communication SoC with integrated 2 MB on-chip SRAM (ECC), dual Gigabit Ethernet MACs, Advanced 5-Port Switch (A5PSW), EtherCAT Slave Controller (3 ports), SercosIII Slave Controller (2 ports), and hardware-accelerated real-time Ethernet functions. It targets deterministic industrial automation gateways requiring IEEE 1588 time synchronization, PRP/HSR redundancy, and multi-protocol fieldbus coexistence.

For engineers reviewing the R9A06G032VGBG#AC1 datasheet, R9A06G032VGBG#AC1 pinout, R9A06G032VGBG#AC1 application, or R9A06G032VGBG#AC1 equivalent, key selection criteria include dual-A7/M3 asymmetric processing, 400-pin LFBGA package with DDR2/3 and RGMII interfaces, integrated A5PSW with QoS and IEEE 1588 support, and verified EtherCAT/SercosIII slave functionality - all validated for industrial temperature range (−40°C to +110°C).

Technical Context

The R9A06G032VGBG#AC1 implements a heterogeneous dual-CPU architecture: two coherent Cortex-A7 cores handle high-level protocol stacks (e.g., EtherNet/IP, Profinet), while the dedicated Cortex-M3 runs real-time tasks including R-IN Engine's HW-RTOS and Ethernet acceleration firmware. Its memory subsystem includes 2 MB ECC-protected SRAM split into two 1 MB banks with independent access ports.

Networking is implemented via three parallel paths: (1) two independent GMACs supporting 10/100/1000 Mbps with full IEEE 1588-2008 timestamping; (2) the A5PSW providing 5-port switching with per-port RMON, VLAN, and TDMA scheduling; and (3) offloaded EtherCAT/SercosIII controllers with dedicated FMMUs, SyncManagers, and distributed clock handling - all operating without CPU intervention.

FAQ

What is the maximum operating frequency of the Cortex-A7 cores in the R9A06G032VGBG#AC1?

The R9A06G032VGBG#AC1 features dual Arm Cortex-A7 processors each operating at up to 500 MHz. This frequency is sustained under industrial temperature conditions (−40°C to +110°C) with proper thermal design and 1.15 V core supply regulation. The R9A06G032VGBG#AC1 does not support dynamic voltage and frequency scaling (DVFS) beyond the fixed 500 MHz specification.

Does the R9A06G032VGBG#AC1 support IEEE 1588-2008 Precision Time Protocol?

Yes, the R9A06G032VGBG#AC1 supports IEEE 1588-2008 v2 with hardware timestamping in both its independent GMACs and Advanced 5-Port Switch (A5PSW). It implements 1-step P2P and E2E modes at Layer 2, and complies with the IEEE C37.238 power profile - enabling sub-100 ns time synchronization accuracy required for substation automation and motion control.

How many EtherCAT slave ports does the R9A06G032VGBG#AC1 support?

The R9A06G032VGBG#AC1 integrates a dedicated EtherCAT Slave Controller supporting up to 3 physical ports. Each port implements full hardware offload including FMMU mapping, SyncManager management, distributed clock synchronization, and automatic TX shift - eliminating CPU involvement in cyclic process data exchange.

What is the on-chip SRAM capacity and ECC capability of the R9A06G032VGBG#AC1?

The R9A06G032VGBG#AC1 includes 2 MB of on-chip SRAM organized as two independent 1 MB banks, each with SEC-DED (Single Error Correction, Double Error Detection) ECC protection. This configuration allows concurrent access by Cortex-A7 and Cortex-M3 subsystems while ensuring data integrity in radiation-prone industrial environments.

Is the R9A06G032VGBG#AC1 pin-compatible with other RZ/N1D group devices?

The R9A06G032VGBG#AC1 uses the 400-pin LFBGA package (17×17 mm, 0.8 mm pitch) and shares identical pinout with other RZ/N1D-400 variants like R9A06G032EGBG#AC1 and R9A06G032NGBG#AC1. However, it is not pin-compatible with RZ/N1D-324 or RZ/N1S/RZ/N1L packages due to differing ball counts and signal allocations.
