Renesas R7S910036CBG#AC0

Overview

R7S910036CBG#AC0 from Renesas Electronics is a high-performance real-time MCU featuring dual Arm Cortex-R4 (600 MHz) and Cortex-M3 (150 MHz) processors, 1 Mbyte on-chip extended SRAM with ECC, EtherCAT slave controller (2-port), Ethernet MAC, dual CAN 2.0B interfaces, and integrated safety functions including CRC, IWDTa, and error control module - deployed in industrial motion control systems requiring deterministic low-latency response.

For engineers reviewing the R7S910036CBG#AC0 datasheet, R7S910036CBG#AC0 pinout, R7S910036CBG#AC0 application, or R7S910036CBG#AC0 equivalent, key selection considerations include confirmed 600 MHz Cortex-R4 operation, 1 Mbyte ECC-protected SRAM, EtherCAT slave compliance (Beckhoff IP core), dual CAN channel support at 1 Mbps, and -40°C to +125°C junction temperature rating.

Technical Context

The R7S910036CBG#AC0 implements a tightly coupled dual-core architecture: the Cortex-R4 executes hard real-time motion control loops with 996 DMIPS at 600 MHz and hardware FPU for single/double-precision math, while the Cortex-M3 (150 MHz) handles auxiliary tasks like communication stack management and safety monitoring. Both cores share access to 1 Mbyte ECC-protected SRAM and support independent MPU-based memory protection.

Its peripheral subsystem integrates EtherCAT slave controller (2-port), Ethernet MAC with MII/RMII, dual CAN controllers compliant with ISO 11898-1, 5-channel SCIFA with 16-byte FIFOs, and 2-unit DMAC (32 channels total) - all coordinated via Event Link Controller (ELC) to enable CPU-sleep-state module chaining without software intervention.

FAQ

What is the maximum operating frequency of the R7S910036CBG#AC0 Cortex-R4 core?

The R7S910036CBG#AC0 operates its Arm Cortex-R4 core at a maximum frequency of 600 MHz, delivering 996 DMIPS performance. This frequency is confirmed in Table 1.1 of the R01DS0228EJ0200 datasheet and applies specifically to the 320-pin FBGA variants including R7S910036CBG#AC0. The device also supports lower-frequency configurations (300/450 MHz) via software configuration.

Does the R7S910036CBG#AC0 include an integrated EtherCAT slave controller?

Yes, the R7S910036CBG#AC0 includes a Beckhoff Automation-certified EtherCAT Slave Controller (ECATC) IP core supporting two ports. This is explicitly listed in Table 1.3 (List of Products) and detailed in Section 1.1 of the datasheet. The ECATC enables direct implementation of EtherCAT slave nodes without external protocol ASICs.

What is the on-chip SRAM capacity and ECC capability of the R7S910036CBG#AC0?

The R7S910036CBG#AC0 integrates 1 Mbyte of on-chip extended SRAM with SEC-DED (single error correction/double error detection) ECC protection. This is specified in Table 1.1 under "Memory" and confirmed in the product list (Table 1.3), where R7S910036CBG#AC0 is grouped with other "1 Mbyte" variants such as R7S910006CBG and R7S910013CBG.

Which communication interfaces are supported by the R7S910036CBG#AC0 for industrial fieldbus connectivity?
