Renesas R7S910015CBA#BC0

Overview

R7S910015CBA#BC0 from Renesas Electronics is a high-performance real-time industrial MCU integrating an Arm Cortex-R4 core (450 MHz) and an on-chip Arm Cortex-M3 co-processor (150 MHz) for R-IN engine functions, 1 Mbyte on-chip extended SRAM with ECC, dual CAN 2.0B interfaces (1 Mbps), and EtherCAT slave controller (2-port). It targets deterministic motion control systems requiring sub-microsecond interrupt latency and synchronized multi-axis servo drive coordination.

For engineers reviewing the R7S910015CBA#BC0 datasheet, R7S910015CBA#BC0 pinout, R7S910015CBA#BC0 application, or R7S910015CBA#BC0 equivalent, key selection criteria include verified R-IN engine support, 320-pin FBGA package compatibility (PRBG0320GB-A), 450 MHz Cortex-R4 operation with TCM/ECC, dual CAN channel routing, and EtherCAT slave timing compliance per IEC 61158 Type 12.

Technical Context

The R7S910015CBA#BC0 implements a dual-core heterogeneous architecture: the Cortex-R4 handles high-speed real-time control loops and safety-critical tasks with 512 KB ATCM + 32 KB BTCM (both ECC-protected), while the dedicated Cortex-M3 executes R-IN engine firmware for industrial protocol offload. Its event link controller (ELC) enables hardware-triggered timer and A/D operations without CPU intervention, preserving deterministic response during sleep mode.

Timing integrity is enforced via independent watchdog (IWDTa, clocked at ≤120 kHz), input clock oscillation stop detection, and error control module (ECM) that generates internal reset or pin assertion on module-level faults. The device supports IEEE 1588 timestamping in Ethernet MAC and hardware-accelerated EtherCAT slave processing with 2-port PHY interface.

FAQ

What is the maximum operating frequency of the Cortex-R4 core in R7S910015CBA#BC0?

The Cortex-R4 core in R7S910015CBA#BC0 operates at a maximum frequency of 450 MHz. This is confirmed in Table 1.3 (List of Products) of the R01DS0228EJ0200 datasheet, which explicitly lists "450 MHz" under Operating Frequency (max.) for R7S910015CBA. The device does not support the 600 MHz variant found in other RZ/T1 family members like R7S910013CBA.

Does R7S910015CBA#BC0 include the R-IN engine, and what does it comprise?

Yes, R7S910015CBA#BC0 incorporates the R-IN engine, implemented as a dedicated Arm Cortex-M3 processor running at 150 MHz. As documented on page 10 of the datasheet, this co-processor executes industrial communication protocol stacks offloaded from the main Cortex-R4, enabling concurrent real-time control and fieldbus handling without CPU contention.

What package type and dimensions does R7S910015CBA#BC0 use?

R7S910015CBA#BC0 uses the PRBG0320GB-A package: a 320-pin Fine-Pitch Ball Grid Array measuring 17 mm × 17 mm with 0.8 mm ball pitch. This is specified in the "Package" section on page 8 of the R01DS0228EJ0200 datasheet and confirmed in Table 1.3 for the R7S910015CBA part number.

Is EtherCAT slave functionality included in R7S910015CBA#BC0, and how many ports does it support?

Yes, R7S910015CBA#BC0 includes EtherCAT slave controller (ECATC) functionality supporting two ports, as stated in the "Communication function" section (page 6) and Table 1.2 (Comparison of Functions). This is an optional feature enabled in the R7S910015 series and distinct from the base Ethernet MAC port.

What is the on-chip SRAM capacity and ECC implementation for R7S910015CBA#BC0?

R7S910015CBA#BC0 integrates 1 Mbyte of on-chip extended SRAM with SEC-DED (single error correction/double error detection) ECC protection. This is explicitly listed in Table 1.1 (Outline of Specifications, page 2) and confirmed in Table 1.3, where "1 Mbyte" appears under On-Chip Extended SRAM Capacity for R7S910015CBA variants.
