Product details
Overview
R7S910018CBA#BC0 from Renesas Electronics is a high-performance industrial real-time MCU featuring an Arm® Cortex-R4 processor (r1p4) operating at 450 MHz, delivering 747 DMIPS, with 1 Mbyte on-chip extended SRAM (ECC-protected), dual CAN 2.0B interfaces (1 Mbps), and integrated EtherCAT slave controller (2-port). It targets deterministic motion control systems requiring sub-microsecond jitter, such as servo drives and PLCs.
For engineers reviewing the R7S910018CBA#BC0 datasheet, R7S910018CBA#BC0 pinout, R7S910018CBA#BC0 application, or R7S910018CBA#BC0 equivalent, key selection criteria include real-time interrupt latency (<100 ns), dual-CAN + EtherCAT coexistence, 450 MHz deterministic execution, Tj = −40°C to +125°C operation, and FBGA-320 package compatibility with industrial PCB layout constraints.
Technical Context
The R7S910018CBA#BC0 implements a dual-core architecture with a primary Arm Cortex-R4 core (450 MHz, Harvard, 8-stage pipeline, TCM + cache ECC) for hard real-time control, and no integrated Cortex-M3 - confirming it lacks the R-IN engine per Table 1.2. Its event link controller (ELC) enables hardware-triggered peripheral chaining without CPU intervention, critical for synchronized PWM, A/D conversion, and encoder capture.
It integrates dedicated safety modules including register write protection, input clock oscillation stop detection, CRC calculator (32-/16-/8-bit polynomials), and error control module (ECM) with dual-master checker logic. The device supports IEEE 1588 timestamping via Ethernet MAC and includes hardware-accelerated EtherCAT slave functionality compliant with Beckhoff's ECATC IP core.

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial real-time MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7S910006CBA | No EtherCAT slave controller; same 450 MHz Cortex-R4, 1 Mbyte SRAM, dual CAN. | Lacks hardware EtherCAT offload - requires software stack + external PHY, increasing CPU load and jitter. | Select when EtherCAT is not required and cost reduction is prioritized over deterministic cycle times. |
| R7S910013CBA | 600 MHz Cortex-R4, same package, EtherCAT + encoder interfaces (EnDat/BiSS-C), no R-IN engine. | Higher compute headroom for advanced filtering or multi-axis interpolation; supports absolute encoder feedback natively. | Select for next-gen servo drives needing >747 DMIPS and EnDat 2.2 encoder support without adding FPGA logic. |
Compared with R7S910006CBA, R7S910018CBA#BC0 adds hardware EtherCAT slave capability and retains identical SRAM and CAN resources; compared with R7S910013CBA, it trades 600 MHz performance and encoder I/F for lower power and cost while preserving EtherCAT and dual CAN - making it optimal for cost-sensitive, EtherCAT-only motion nodes.

Yes, the R7S910018CBA#BC0 integrates a Beckhoff-certified EtherCAT Slave Controller (ECATC) supporting two ports. This hardware IP core handles frame processing, distributed clock synchronization, and mailbox communication - offloading >90% of EtherCAT protocol stack execution from the Cortex-R4 core and enabling sub-1 µs jitter in motion networks.
What package type is used for the R7S910018CBA#BC0?
The R7S910018CBA#BC0 uses the PRBG0320GB-A package: a 320-ball Fine-Pitch Ball Grid Array measuring 17 mm × 17 mm with 0.8 mm pitch. This FBGA variant is pin-compatible with other RZ/T1 320-pin variants (e.g., PRBG0320GA-A) and supports standard industrial reflow profiles and thermal via implementation.
How much on-chip SRAM does the R7S910018CBA#BC0 provide?
The R7S910018CBA#BC0 includes 1 Mbyte of on-chip extended SRAM with SEC-DED (single-error correction, double-error detection) ECC protection. This memory operates at 150 MHz and is mapped as unified RAM - usable for code, stack, heap, and real-time buffers without external memory access latency.
Is the R7S910018CBA#BC0 qualified for industrial temperature operation?
Yes, the R7S910018CBA#BC0 is fully qualified for industrial junction temperature operation from −40°C to +125°C. This rating is validated across all integrated peripherals - including EtherCAT, CAN, A/D converters, and SRAM - with no derating required, making it suitable for uncooled drive cabinets and factory-floor environments.
