Product details
Overview
R7S910026CBA#BC0 from Renesas Electronics is a high-performance real-time MCU featuring an Arm Cortex-R4 processor (r1p4) operating at 450 MHz, integrated 1 Mbyte on-chip extended SRAM with ECC, dual Ethernet MAC support (with switch), and dual CAN 2.0B interfaces - deployed in industrial motion control systems requiring deterministic low-latency response and functional safety compliance.
For engineers reviewing the R7S910026CBA#BC0 datasheet, R7S910026CBA#BC0 pinout, R7S910026CBA#BC0 application, or R7S910026CBA#BC0 equivalent, key selection considerations include its 320-pin FBGA package (PRBG0320GB-A), 450 MHz Cortex-R4 core with FPU and TCM, EtherCAT slave controller option, encoder interface capability (EnDat 2.2/BiSS-C), and -40°C to +125°C junction temperature rating.
Technical Context
The R7S910026CBA#BC0 implements a dual-core architecture with a primary Cortex-R4 core (450 MHz, 747 DMIPS) and optional Cortex-M3 co-processor (150 MHz) for R-IN engine-enabled variants - though this specific variant omits the R-IN engine per Table 1.2. It integrates tightly coupled memory (ATCM: 512 KB, BTCM: 32 KB), instruction/data caches (8 KB each, ECC-protected), and a memory protection unit (MPU) for ASIL-B–capable system partitioning.
Real-time determinism is enforced via hardware event linking (ELC), supporting up to 103 inter-module event triggers without CPU intervention, and includes dedicated peripherals for motor control: MTU3a (9-channel 16/32-bit timer), GPTa (4-channel PWM), TPUa (12-channel pulse I/O), and POE3 for safe PWM output disable. Safety is addressed through register write protection, CRC calculator (32-/16-/8-bit polynomials), input clock oscillation detection, and error control module (ECM) with dual-master checker logic.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7S910006CBA | Same 320-pin FBGA package and 450 MHz Cortex-R4 core, but lacks EtherCAT slave controller and encoder interface IP blocks. | Suitable for non-EtherCAT applications such as standalone CAN-based motion controllers or general-purpose industrial gateways. | Select when EtherCAT or EnDat/BiSS-C position feedback is not required - reduces BOM cost and simplifies firmware stack. |
| R7S910013CBA | Identical package and core, but rated for 600 MHz operation (996 DMIPS) and includes optional encoder interface (EnDat 2.2/BiSS-C). | Targeted at higher-performance servo drives requiring faster current loop bandwidth (>60 kHz) and dual-encoder feedback (e.g., motor + load). | Choose for future-proofing or applications demanding >747 DMIPS; verify thermal design supports 600 MHz sustained operation. |

FAQ
What is the maximum operating frequency of the R7S910026CBA#BC0?
The R7S910026CBA#BC0 operates at a maximum CPU frequency of 450 MHz on its Arm Cortex-R4 core, delivering 747 DMIPS performance. This frequency is factory-configured and validated for continuous operation within the -40°C to +125°C junction temperature range, with power supply rails stabilized at 1.14–1.26 V for the core domain. The R7S910026CBA#BC0 does not support 600 MHz operation - that capability is reserved for variants like R7S910013CBA.
Does the R7S910026CBA#BC0 include the R-IN Engine with Cortex-M3?
No, the R7S910026CBA#BC0 does not incorporate the R-IN Engine or the secondary Arm Cortex-M3 processor. Per Table 1.2 in the R01DS0228EJ0200 datasheet, R-IN Engine functionality is absent in this variant. Its real-time capabilities rely solely on the 450 MHz Cortex-R4 core, ELC hardware event routing, and dedicated peripherals like MTU3a and GPTa - making it suitable for applications where deterministic single-core execution is preferred over dual-core partitioning.
Which encoder protocols are supported by the R7S910026CBA#BC0?
The R7S910026CBA#BC0 supports EnDat 2.2, BiSS-C, FA-CODER, A-format, and HIPERFACE DSL encoder interfaces via its optional 2-channel encoder interface block. These protocols are implemented in hardware and require no software protocol stack - reducing CPU overhead and jitter. Support is confirmed in the "Encoder interfaces (optional)" section of the datasheet and applies specifically to the R7S910026CBA#BC0's PRBG0320GB-A package configuration.
What safety certifications does the R7S910026CBA#BC0 target?
The R7S910026CBA#BC0 integrates hardware safety mechanisms aligned with IEC 61508 SIL2 and ISO 13849 PLd requirements, including register write protection, CRC calculator (32-/16-/8-bit), input clock oscillation detection, error control module (ECM) with dual-master checker logic, and memory ECC. While Renesas provides safety manuals and FMEDA reports, final certification is system-level and depends on implementation - the R7S910026CBA#BC0 itself serves as a foundational safety-capable component in certified drives and controllers.
Is the 1 Mbyte on-chip SRAM in the R7S910026CBA#BC0 protected with ECC?
Yes, the full 1 Mbyte of on-chip extended SRAM in the R7S910026CBA#BC0 implements SEC-DED (single error correction/double error detection) ECC, as explicitly stated in the "On-chip extended SRAM with ECC" feature list and Table 1.1 of the datasheet. This ECC protection applies to all read/write accesses and is transparent to software - critical for maintaining data integrity in safety-critical motion control buffers and EtherCAT process data objects.
