Product details
Overview
R7S910002CBA#BC0 from Renesas Electronics is a 320-pin FBGA high-integrity real-time MCU featuring an Arm Cortex-R4 core operating at 450 MHz, 8 KB instruction/data caches with ECC, 512 KB ATCM + 32 KB BTCM with ECC, and integrated EtherCAT slave controller (2-port), Ethernet MAC, dual CAN 2.0B, USB 2.0 HS, and 12-bit A/D converters - deployed in industrial motion control systems requiring deterministic response and functional safety support.
For engineers reviewing the R7S910002CBA#BC0 datasheet, R7S910002CBA#BC0 pinout, R7S910002CBA#BC0 application, or R7S910002CBA#BC0 equivalent, this page delivers verified specifications, package mapping to PRBG0320GB-A, confirmed peripheral channel counts (TPUa ×12, MTU3a ×9, SCIFA ×5, CAN ×2), safety features (ECM, IWDTa, CRC), and real-world use context for servo drives, PLCs, and EtherCAT-enabled automation controllers.
Technical Context
The R7S910002CBA#BC0 implements a dual-domain real-time architecture: its Cortex-R4 core executes time-critical motion control loops at 450 MHz with Harvard pipeline, TCM+ECC, and FPU support for single/double-precision math, while dedicated hardware accelerators - including event link controller (ELC) and port output enable (POE3) - enable deterministic I/O response without CPU intervention. It integrates EtherCAT slave IP (Beckhoff-licensed) with full 2-port operation and IEEE 1588 timestamping via Ethernet switch logic.
Peripheral subsystems are tightly coupled to timing integrity: DMAC supports 32-channel transfers across two units with configurable burst sizes; TPUa/MTU3a/GPTa timers deliver synchronized PWM generation (complementary, dead-time compensated, 3-phase) and A/D trigger alignment; S12ADCa provides 8-channel unit 0 conversion at 0.483 µs/channel with self-diagnosis and disconnection detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time industrial MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7S910007CBA#BC0 | Same PRBG0320GB-A package, but rated for 600 MHz CPU frequency and 996 DMIPS - includes higher-speed TCM access timing and enhanced PLL stability margins. | Required for applications demanding >747 DMIPS compute headroom (e.g., multi-axis spline interpolation with real-time collision avoidance). | Select when deterministic execution at >450 MHz is mandatory; verify thermal design for +125°C junction operation at sustained 600 MHz. |
| R7S910006CBA#BC0 | Identical 450 MHz operation and package, but adds 1 Mbyte on-chip extended SRAM with ECC - no change to TCM/cache sizes or peripheral channel count. | Suitable for firmware-over-the-air (FOTA) updates, dual-bank flash emulation, or large lookup tables in advanced motor control algorithms. | Choose when runtime data buffering or secure boot image staging exceeds 512 KB ATCM capacity - no PCB or firmware changes needed beyond memory map update. |
Compared with R7S910007CBA#BC0 and R7S910006CBA#BC0, the R7S910002CBA#BC0 offers optimal balance of 450 MHz real-time performance, full EtherCAT 2-port capability, and safety-certifiable memory subsystem - making it the preferred choice for cost-sensitive, thermally constrained servo drives where 600 MHz headroom or 1 MB SRAM are unnecessary.

FAQ
What is the maximum operating frequency of the R7S910002CBA#BC0?
The R7S910002CBA#BC0 operates at a maximum CPU frequency of 450 MHz, delivering 747 DMIPS performance. This rating is validated for the PRBG0320GB-A package under industrial temperature conditions (Tj = –40°C to +125°C) and requires proper power sequencing and thermal management per Renesas AN-900001 layout guidelines. The R7S910002CBA#BC0 does not support 600 MHz operation - that capability is exclusive to the R7S910007xxx series.
Does the R7S910002CBA#BC0 include EtherCAT slave functionality?
Yes, the R7S910002CBA#BC0 integrates a licensed EtherCAT slave controller (ECATC) supporting two physical ports, compliant with EtherCAT protocol specifications and capable of sub-100 µs cycle times. This function is silicon-hardened and enabled by default - no external FPGA or ASIC is required. Configuration is performed via the ECATC registers mapped in the R7S910002CBA#BC0's address space, and initialization uses standard EtherCAT mailbox protocols.
What analog-to-digital converter resources are available on the R7S910002CBA#BC0?
The R7S910002CBA#BC0 includes the S12ADCa 12-bit A/D converter with Unit 0 only (8 channels: AN000–AN007), offering 0.483 µs per channel conversion time, sample-and-hold circuitry, self-diagnostic capability, and disconnection detection. Unit 1 (16 channels) is not implemented in this variant - confirmed in Table 1.2 of the R01DS0228EJ0200 datasheet. Conversion triggers may originate from software, TPUa/MTU3a/GPTa timers, or external pins.
Is on-chip extended SRAM included in the R7S910002CBA#BC0?
No, the R7S910002CBA#BC0 does not include the 1 Mbyte on-chip extended SRAM option. Per Table 1.3 of the R01DS0228EJ0200 datasheet, only variants with "006" or "007" in the part number (e.g., R7S910006CBA#BC0) feature this memory. The R7S910002CBA#BC0 relies solely on its 512 KB ATCM + 32 KB BTCM for tightly coupled code and data storage - sufficient for real-time control kernels but not for large buffer or firmware staging applications.
What safety mechanisms are implemented in the R7S910002CBA#BC0?
The R7S910002CBA#BC0 incorporates multiple hardware safety mechanisms: Error Control Module (ECM) for error signal aggregation and internal reset generation; Independent Watchdog Timer (IWDTa) clocked by LOCO/2 (120 kHz); CRC calculator supporting four polynomials; register write protection; and input clock oscillation stop detection. These features collectively support IEC 61508 SIL2 and ISO 13849 PL e compliance when implemented per Renesas Functional Safety Manual R01US0097EJ0300.
