Overview

R7S910006CBG#AC0 from Renesas Electronics is a high-performance real-time MCU featuring a 450 MHz Arm Cortex-R4 processor with FPU, 1 Mbyte on-chip extended SRAM with ECC, dual CAN 2.0B interfaces (1 Mbps), Ethernet MAC (10/100BASE-TX), and industrial-grade operation up to +125°C junction temperature - deployed in servo drive motion control systems requiring deterministic low-latency response.

For engineers reviewing the R7S910006CBG#AC0 datasheet, R7S910006CBG#AC0 pinout, R7S910006CBG#AC0 application, or R7S910006CBG#AC0 equivalent, key selection criteria include its 450 MHz Cortex-R4 core with TCM/ECC memory, EtherCAT-ready peripheral set (though not enabled in this variant), 176 I/O pins in 320-pin FBGA, and support for safety-critical industrial automation via CRC, IWDTa, and error control module (ECM).

Technical Context

The R7S910006CBG#AC0 implements a single-core Arm Cortex-R4 (r1p4) architecture with Harvard pipeline, 8 KB instruction/data caches (ECC-protected), 512 KB ATCM + 32 KB BTCM (ECC), and MPU - optimized for hard real-time deterministic execution in motor control and PLC edge nodes. It integrates DMAC (32 channels), event link controller (ELC) for CPU-sleep-linked peripheral triggering, and multi-function pin controller (MPC) for flexible signal routing.

Its peripheral suite includes two independent CAN controllers compliant with ISO 11898-1, an Ethernet MAC supporting MII/RMII, USB 2.0 HS host/function, five SCIFA UARTs with 16-byte FIFOs, and dual 12-bit A/D converters (8+16 channels) with self-diagnosis and analog disconnection detection - all operating under dual voltage rails (1.2 V core / 3.3 V I/O) and qualified for Tj = −40°C to +125°C.

FAQ

What is the maximum operating frequency of the R7S910006CBG#AC0?

The R7S910006CBG#AC0 operates at a maximum CPU frequency of 450 MHz, delivering 747 DMIPS performance. This frequency is fixed for this specific part number and is achieved using the on-chip PLL driven by a 25 MHz external crystal. The 450 MHz rating is validated across the full −40°C to +125°C junction temperature range with appropriate power supply regulation.

Does the R7S910006CBG#AC0 include EtherCAT slave functionality?

No, the R7S910006CBG#AC0 does not include EtherCAT slave controller (ECATC) functionality. While the RZ/T1 Group datasheet lists EtherCAT as optional, Table 1.3 explicitly states "Not supported" for EtherCAT in the R7S910006CBG#AC0 row. This part includes only the standard Ethernet MAC (ETHERC) with MII/RMII interface, not the Beckhoff IP-based ECATC block.

What package type and pin count does the R7S910006CBG#AC0 use?

The R7S910006CBG#AC0 uses a 320-pin Fine-Pitch Ball Grid Array (FBGA) package designated PRBG0320GA-A, measuring 17 mm × 17 mm with 0.8 mm ball pitch. It provides 209 general-purpose I/O pins, 9 dedicated 5-V-tolerant inputs, and integrated thermal pad for industrial thermal management.

How much on-chip SRAM does the R7S910006CBG#AC0 have, and is it ECC-protected?

The R7S910006CBG#AC0 integrates 1 Mbyte of on-chip extended SRAM with full SEC-DED (single error correction/double error detection) ECC protection. This memory operates at 150 MHz and is accessible by both the Cortex-R4 core and DMA controllers, providing fault-resilient data storage for real-time control buffers and communication stacks.

Which communication interfaces are supported by the R7S910006CBG#AC0?

The R7S910006CBG#AC0 supports CAN (2 channels, ISO 11898-1, up to 1 Mbps), Ethernet MAC (1 port, 10/100BASE-TX, MII/RMII), USB 2.0 HS host/function, SCIFA (5 channels with 16-byte FIFOs), RIIC (2 channels, up to 400 kbps), RSPIa (4 channels), SPIBSC (1 channel for quad-SPI flash), and SSI (1 channel). It does not include EtherCAT or R-IN Engine peripherals.
