Product details
Overview
R7S910027CBA#BC0 from Renesas Electronics is a high-performance 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, Ethernet MAC, 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 R7S910027CBA#BC0 datasheet, R7S910027CBA#BC0 pinout, R7S910027CBA#BC0 application, or R7S910027CBA#BC0 equivalent, this page delivers verified specifications, package mapping to PRBG0320GB-A FBGA, validated peripheral channel counts (e.g., 2× CAN, 5× SCIFA, 2× RIIC), safety features (CRC, IWDTa, register write protection), and direct alternative options for industrial automation MCU selection.
Technical Context
The R7S910027CBA#BC0 implements a dual-core architecture with a primary Arm Cortex-R4 core (450 MHz, 747 DMIPS) and no integrated Cortex-M3 (R-IN Engine omitted per Table 1.3), using Harvard architecture with 8-stage pipeline, ECC-protected 8 KB instruction/data caches, and 512 KB ATCM/32 KB BTCM TCM. It supports Arm v7-R instruction set, little-endian data, and MPU-based memory protection.
Real-time determinism is enforced via Event Link Controller (ELC) enabling module-triggered operation without CPU wake-up, 33 timers including MTU3a (9-channel), TPUa (12-channel), and GPTa (4-channel) with PWM, input capture, and A/D trigger generation, plus dedicated hardware safety logic (ECM, CLMA, DOC) for fault detection and response.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7S910006CBA | Same PRBG0320GB-A package, identical 450 MHz Cortex-R4 core and 1 MB ECC SRAM, but lacks optional encoder interface support. | Targeted at non-encoder applications (e.g., general-purpose motion control without absolute position feedback). | Select when EnDat/BiSS-C interface is unnecessary - lower cost, same footprint and software compatibility. |
| R7S910007CBA | Same package and feature set, but rated for 600 MHz (996 DMIPS); requires higher VDD stability and thermal management. | Suitable for computationally intensive tasks like multi-axis coordinated motion or real-time vision preprocessing. | Choose only if 450 MHz headroom is insufficient; verify power delivery and thermal design meet 600 MHz requirements. |
Compared with R7S910027CBA#BC0, R7S910006CBA offers identical real-time performance without encoder interface overhead, while R7S910007CBA trades higher power and thermal demand for 33% more DMIPS - both retain full pin compatibility and software ecosystem alignment.

FAQ
What is the maximum operating frequency of the R7S910027CBA#BC0?
The R7S910027CBA#BC0 operates at a maximum CPU frequency of 450 MHz, delivering 747 DMIPS. This frequency is fixed for this specific part number per Table 1.3 in the R01DS0228EJ0200 datasheet; it does not support 300 MHz or 600 MHz configurations. The 450 MHz rating is guaranteed across the full −40°C to +125°C junction temperature range with appropriate power supply decoupling and thermal management.
Does the R7S910027CBA#BC0 include an integrated Cortex-M3 core?
No, the R7S910027CBA#BC0 does not incorporate the Cortex-M3 core (R-IN Engine). Per Table 1.3 in the R01DS0228EJ0200 datasheet, only part numbers ending in "15" (e.g., R7S910015CBA) include the 150 MHz Cortex-M3. The R7S910027CBA#BC0 contains only the Arm Cortex-R4 core, making it optimized for single-core deterministic real-time workloads without auxiliary control offload.
What package type is used for the R7S910027CBA#BC0?
The R7S910027CBA#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 package is RoHS-compliant and thermally enhanced for industrial applications. It is mechanically and electrically identical to PRBG0320GA-A and PLBG0320GB-A variants, ensuring drop-in replacement within the RZ/T1 320-pin family.
Which safety features are implemented in the R7S910027CBA#BC0?
The R7S910027CBA#BC0 integrates multiple hardware safety mechanisms: CRC calculator supporting four standard polynomials, independent watchdog timer (IWDTa) clocked by LOCO/2, register write protection for critical control registers, error control module (ECM) that generates interrupts/resets on module faults, and clock monitor circuit (CLMA) detecting PLL or LOCO anomalies. These features collectively support IEC 61508 SIL2 compliance when properly configured in the application.
Is EtherCAT supported on the R7S910027CBA#BC0?
No, EtherCAT Slave Controller (ECATC) functionality is not enabled on the R7S910027CBA#BC0. According to Table 1.2 and Table 1.3 in the datasheet, EtherCAT is marked as "optional" and only available on part numbers explicitly designated with "11", "13", or "15" suffixes (e.g., R7S910011CBA). The R7S910027CBA#BC0 includes only the standard Ethernet MAC (ETHERC) for 10/100BASE-T communication.
