Renesas R7S910017CBA#BC0

Overview

R7S910017CBA#BC0 from Renesas Electronics is a high-performance real-time MCU featuring an Arm Cortex-R4 processor (r1p4) operating at 450 MHz, 1 Mbyte on-chip extended SRAM with ECC, dual CAN 2.0B interfaces (1 Mbps), EtherCAT slave controller (2-port), 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 R7S910017CBA#BC0 datasheet, R7S910017CBA#BC0 pinout, R7S910017CBA#BC0 application, or R7S910017CBA#BC0 equivalent, key selection criteria include verified EtherCAT slave timing compliance, 450 MHz real-time execution capability, 1 Mbyte on-chip ECC SRAM allocation for safety-critical firmware/data, and PRBG0320GB-A FBGA package compatibility with industrial PCB thermal management requirements.

Technical Context

The R7S910017CBA#BC0 implements a dual-core architecture with a primary Cortex-R4 core (450 MHz, 498 DMIPS) and no integrated Cortex-M3 - distinguishing it from R-IN Engine variants. Its memory subsystem includes 512 Kbytes ATCM + 32 Kbytes BTCM (both with ECC), 8 Kbytes instruction and data caches (ECC-protected), and 1 Mbyte extended SRAM (150 MHz, SEC-DED).

Real-time peripheral coordination is enabled by the Event Link Controller (ELC), supporting up to 103 inter-module event signals without CPU intervention. Safety is enforced via register write protection, input clock oscillation detection, CRC calculator (four polynomials), IWDTa (14-bit, LOCO/2 clock source), and error control module (ECM) with dual master/checker redundancy.

FAQ

What is the maximum operating frequency of the R7S910017CBA#BC0?

The R7S910017CBA#BC0 operates at a maximum CPU frequency of 450 MHz on its Arm Cortex-R4 core, delivering 498 DMIPS performance. This frequency is fully supported across the PRBG0320GB-A package variant and is validated for continuous operation within the −40°C to +125°C junction temperature range. The R7S910017CBA#BC0 does not support the 600 MHz mode found in higher-tier RZ/T1 variants like R7S910013CBA#BC0.

Does the R7S910017CBA#BC0 include an integrated EtherCAT slave controller?

Yes, the R7S910017CBA#BC0 integrates a Beckhoff-licensed EtherCAT slave controller (ECATC) supporting two physical ports, enabling direct implementation of EtherCAT slave nodes without external ASICs. This controller is silicon-verified for cycle times down to 100 µs and supports distributed clocks, DC synchronization, and process data mapping per EtherCAT specification ETG.1000. The R7S910017CBA#BC0 implements this function as standard - no NDA or optional license activation is required.

What memory resources are available on-chip for the R7S910017CBA#BC0?

The R7S910017CBA#BC0 provides 1 Mbyte of on-chip extended SRAM with SEC-DED (single-error correction/double-error detection) ECC, plus 512 Kbytes of ATCM and 32 Kbytes of BTCM - all protected by ECC. It also includes 8 Kbytes of instruction cache and 8 Kbytes of data cache, both ECC-protected. No external memory interface is required for typical motion control firmware, as the full 1 Mbyte SRAM is accessible at 150 MHz for deterministic real-time execution.

Is the R7S910017CBA#BC0 qualified for industrial temperature operation?

Yes, the R7S910017CBA#BC0 is fully specified and tested for operation across a junction temperature range of −40°C to +125°C, meeting industrial-grade reliability standards. This qualification covers all core functions - including Cortex-R4 execution, EtherCAT slave timing, CAN transceiver interface, 12-bit A/D conversion, and 1 Mbyte ECC SRAM - ensuring parameter stability and timing margin retention in sealed, fanless enclosures typical of motor drive applications.

What package type is used for the R7S910017CBA#BC0?

The R7S910017CBA#BC0 is supplied in the PRBG0320GB-A package: a 320-ball Fine-Pitch Ball Grid Array measuring 17 mm × 17 mm with 0.8 mm ball pitch. This RoHS-compliant, lead-free FBGA package features optimized thermal vias and copper layers for efficient heat dissipation in high-power industrial PCBs, and is pin-compatible with other RZ/T1 320-pin variants such as R7S910002CBA#BC0 and R7S910006CBA#BC0.
