Renesas R9A06G032EGBA#AC1

Overview

R9A06G032EGBA#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 R-IN Engine for real-time industrial Ethernet protocols. It targets industrial gateways, PLC controllers, and motion control systems requiring deterministic network timing and protocol offload.

For engineers reviewing the R9A06G032EGBA#AC1 datasheet, R9A06G032EGBA#AC1 pinout, R9A06G032EGBA#AC1 application, or R9A06G032EGBA#AC1 equivalent, this device delivers verified IEEE 1588-2008 P2P/E2E timestamping, PRP/HSR option support, dual DDR2/3-1000 interface, and 170 GPIOs - all in a 324-pin LFBGA (15×15 mm, 0.8 mm pitch) package suitable for high-reliability industrial edge nodes.

Technical Context

The R9A06G032EGBA#AC1 implements a heterogeneous dual-CPU architecture: two Cortex-A7 cores (500 MHz, L1/L2 cache, MMU, FPU) handle Linux-based application processing and protocol stack management, while the dedicated Cortex-M3 core (125 MHz, MPU) runs real-time tasks including R-IN Engine firmware, EtherCAT state machines, and switch control logic. Memory coherency is maintained via hardware cache coherency across both domains.

Its networking subsystem integrates three independent Ethernet domains: the A5PSW (5-port managed switch with QoS, VLAN, IEEE 1588, PRP/HSR), two independent GMACs (10/100/1000 Mbps, jumbo frame up to 16 KB, PPS output on GMAC1), and protocol-specific accelerators for EtherCAT (8 FMMUs, 64-bit DC), SercosIII (100 Mbaud serial interface), and HSR/PRP (IEC 62439-3 Ed2.0 compliant). All operate with deterministic latency under hardware-managed scheduling.

FAQ

What is the maximum operating frequency of the Cortex-A7 cores in the R9A06G032EGBA#AC1?

The R9A06G032EGBA#AC1 features dual Arm Cortex-A7 cores operating at up to 500 MHz. This frequency is supported with appropriate voltage regulation (VDD11 = 1.15 V ± 0.05 V) and thermal management within the −40°C to +110°C junction temperature range. The R9A06G032EGBA#AC1 datasheet confirms this rating under standard industrial conditions with clock frequency scaling enabled.

Does the R9A06G032EGBA#AC1 support IEEE 1588-2008 Precision Time Protocol?

Yes, the R9A06G032EGBA#AC1 supports IEEE 1588-2008 v2 with both 1-step Peer-to-Peer (P2P) and End-to-End (E2E) timestamping modes in its A5PSW and both independent GMACs. Hardware timestamping is applied at the MAC layer with ≤50 ns accuracy, and the R9A06G032EGBA#AC1 includes dedicated registers for PPS output control on GMAC1.

How many EtherCAT ports does the R9A06G032EGBA#AC1 support, and what is the implementation method?

The R9A06G032EGBA#AC1 supports up to three EtherCAT Slave ports via its dedicated EtherCAT Slave Controller. This is implemented as a hardware accelerator within the R-IN Engine, providing 8 FMMUs, 8 SyncManagers, 64-bit distributed clocks, and automatic TX shift - all without loading the Cortex-A7 or Cortex-M3 cores. The R9A06G032EGBA#AC1 datasheet specifies full compliance with EtherCAT protocol timing requirements.

What is the on-chip SRAM capacity and ECC capability of the R9A06G032EGBA#AC1?

The R9A06G032EGBA#AC1 integrates 2 MB of on-chip SRAM with SEC-DED (Single Error Correction, Double Error Detection) ECC protection. This memory is partitioned into two 1 MB banks, each with separate access ports and ECC logic. The R9A06G032EGBA#AC1 uses this SRAM for boot ROM, real-time firmware, and critical protocol buffers - ensuring data integrity in harsh industrial environments.

Is the R9A06G032EGBA#AC1 pin-compatible with other members of the RZ/N1 family?

The R9A06G032EGBA#AC1 uses a 324-pin LFBGA package shared with R9A06G032VGBA#AC1 (same RZ/N1D group) and R9A06G033VGBA#AC1 (RZ/N1S group), but pin functions differ across families. While mechanical footprint matches, signal mapping for DDR, Ethernet, and peripherals varies - making it not pin-compatible with RZ/N1S or RZ/N1L variants. The R9A06G032EGBA#AC1 pinout is documented in Figure 1.5 of the official datasheet.
