Renesas R9A06G033PGBG#AC1

Overview

R9A06G033PGBG#AC1 from Renesas is a single-core Arm Cortex-A7 (500 MHz) + Cortex-M3 (125 MHz) industrial communication SoC with integrated 4 MB ECC SRAM, dual 1 Gbps GMACs, Advanced 5-Port Ethernet Switch (A5PSW), EtherCAT Slave Controller (3 ports), SercosIII Slave Controller (2 ports), and dual CAN interfaces. It targets real-time industrial Ethernet gateways requiring deterministic timing, redundancy protocols (PRP/HSR), and co-processing for protocol stack offload.

For engineers reviewing the R9A06G033PGBG#AC1 datasheet, R9A06G033PGBG#AC1 pinout, R9A06G033PGBG#AC1 application, or R9A06G033PGBG#AC1 equivalent, this device delivers verified support for EtherCAT, SercosIII, Profinet, IEEE 1588-2008 PTP, PRP (IEC 62439-3 Ed2.0), HSR, and DLR - all within a single 324-pin LFBGA package operating from −40°C to +110°C junction temperature.

Technical Context

The R9A06G033PGBG#AC1 implements a heterogeneous dual-CPU architecture: a single Cortex-A7 core handles high-level Linux-based protocol stacks and application logic, while the dedicated Cortex-M3 core-integrated into the R-IN Engine-executes real-time Ethernet acceleration tasks including hardware RTOS scheduling, Ethernet frame processing, and EtherCAT/SercosIII telegram handling. The A5PSW provides full Layer 2 switching with IEEE 1588 timestamping, QoS queues, VLAN filtering, and PRP/HSR redundancy support.

Memory subsystem includes 4 MB on-chip SRAM with SEC-DED ECC, DDR2/3-1000 controller (16-bit bus), NAND Flash controller with BCH ECC up to 32-bit correction, and dual Quad SPI interfaces. Peripherals include 8 UARTs (with RS485/MODBUS support), 6 SPI (4 master/2 slave), 2 I²C, 2 × 12-bit ADCs (1 MSPS), LCD controller, and MSEBI parallel interface.

FAQ

What is the maximum operating frequency of the Cortex-A7 core in R9A06G033PGBG#AC1?

The Cortex-A7 core in R9A06G033PGBG#AC1 operates at up to 500 MHz. This frequency is fixed and verified under industrial temperature conditions (−40°C to +110°C junction). Clock scaling is supported via software configuration, but the maximum guaranteed performance remains 500 MHz across the full operating range. R9A06G033PGBG#AC1 does not support overclocking beyond this specification.

Does R9A06G033PGBG#AC1 support both PRP and HSR simultaneously?

No, R9A06G033PGBG#AC1 does not support PRP and HSR simultaneously. According to the official datasheet (R01DS0323EJ0130 Rev.1.30, Note 5), HW-RTOS and HSR are mutually exclusive, and Note 6 states that SERCOSIII, ETHERCAT, and HSR functions cannot be enabled at the same time. PRP is implemented in the A5PSW, while HSR uses a dedicated switch block - only one can be active per device configuration. R9A06G033PGBG#AC1 supports PRP as a standard feature and HSR as an optional configuration.

How much on-chip SRAM does R9A06G033PGBG#AC1 include, and is ECC enabled by default?

R9A06G033PGBG#AC1 integrates 4 MB of on-chip SRAM with SEC-DED (Single Error Correction, Double Error Detection) ECC protection. ECC is hardware-implemented and always active for all SRAM accesses - it cannot be disabled. The memory is partitioned into two 2 MB banks with separate access ports, enabling concurrent read/write operations without contention. This eliminates the need for external RAM in most industrial gateway implementations.

Which Ethernet protocols are hardware-accelerated in the R-IN Engine of R9A06G033PGBG#AC1?

The R-IN Engine in R9A06G033PGBG#AC1 provides hardware acceleration for EtherCAT Slave (3 ports), SercosIII Slave (2 ports), and IEEE 1588-2008 timestamping. It also includes a hardware RTOS scheduler, dedicated DMA, and buffer allocator optimized for real-time Ethernet frame processing. These functions execute independently of the Cortex-A7 core, enabling deterministic sub-100 µs cycle times while Linux runs on the application processor. R9A06G033PGBG#AC1 does not accelerate PROFINET or EtherNet/IP in hardware - those run in software on the Cortex-A7.

What is the GPIO count and pin multiplexing capability of R9A06G033PGBG#AC1?

R9A06G033PGBG#AC1 provides 132 GPIO pins in its 324-pin LFBGA package. Each GPIO supports programmable drive strength, on-chip pull-up/pull-down resistors, and multiplexing across multiple peripheral functions (UART, SPI, I²C, CAN, etc.). Pin locations for peripherals are selectable from multiple pins via the IO Multiplexing Controller - allowing flexible PCB routing and reuse of pin resources across different board revisions. This capability is documented in Section 1.3 (Function Comparison) and Figure 1.4 of the datasheet.
