Renesas R7S910017CBG#AC0

Overview

R7S910017CBG#AC0 from Renesas Electronics is a high-performance real-time industrial 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), dual CAN 2.0B interfaces, and integrated safety functions including CRC, IWDTa, and error control module - deployed in motion control systems requiring deterministic low-latency response.

For engineers reviewing the R7S910017CBG#AC0 datasheet, R7S910017CBG#AC0 pinout, R7S910017CBG#AC0 application, or R7S910017CBG#AC0 equivalent, key selection considerations include confirmed 600 MHz Cortex-R4 operation, 1 Mbyte ECC SRAM, EtherCAT slave compliance (Beckhoff IP core), -40°C to +125°C junction temperature rating, and PRBG0320GA-A 320-pin FBGA package with 0.8-mm pitch.

Technical Context

The R7S910017CBG#AC0 implements a tightly coupled dual-core architecture: the Cortex-R4 executes hard real-time control tasks at up to 600 MHz with 8 KB instruction/data caches (ECC-protected), TCM (512 KB ATCM + 32 KB BTCM), and FPU supporting single/double-precision operations; the Cortex-M3 (150 MHz) handles auxiliary I/O coordination and R-IN engine support. Both cores share access to the 1 Mbyte ECC-protected extended SRAM and are synchronized via the Event Link Controller (ELC) for event-triggered, sleep-state module operation.

Hardware acceleration includes dedicated peripherals for industrial networking: EtherCAT Slave Controller (ECATC) with 2-port PHY interface compliant to Beckhoff's IP core, Ethernet MAC (1 port, IEEE 802.3, 10/100BASE-TX), dual CAN channels (ISO 11898-1, 1 Mbps), and encoder interface support (EnDat 2.2, BiSS-C, FA-CODER). Safety is enforced via register write protection, input clock oscillation detection, CLMA clock monitor, and ECM-driven internal reset/interrupt generation.

FAQ

What is the maximum operating frequency of the R7S910017CBG#AC0?

The R7S910017CBG#AC0 operates at a maximum CPU clock frequency of 600 MHz on its Arm Cortex-R4 core, with the Cortex-M3 core running at 150 MHz. This frequency is confirmed in the official Renesas datasheet R01DS0228EJ0200 Rev.2.00, Table 1.1, and applies specifically to the 320-pin FBGA variants including R7S910017CBG#AC0. The device achieves 996 DMIPS at this speed.

Does the R7S910017CBG#AC0 include an EtherCAT slave controller?

Yes, the R7S910017CBG#AC0 integrates a certified EtherCAT Slave Controller (ECATC) IP core licensed from Beckhoff Automation GmbH, supporting two ports with sub-1 µs jitter. This is explicitly listed in Table 1.2 (Comparison of Functions) and confirmed in the "Communication function" section of the datasheet, distinguishing it from non-EtherCAT variants like R7S910013CBG#AC0.

What package type does the R7S910017CBG#AC0 use?

The R7S910017CBG#AC0 uses the PRBG0320GA-A package: a 320-pin Fine-Pitch Ball Grid Array measuring 17 mm × 17 mm with 0.8 mm ball pitch. This is verified in Table 1.3 (List of Products) and the "Package" section of the datasheet, and is shared with other 320-pin RZ/T1 variants such as R7S910007CBG#AC0 and R7S910011CBG#AC0.

How much on-chip SRAM does the R7S910017CBG#AC0 provide, and is it ECC-protected?

The R7S910017CBG#AC0 includes up to 1 Mbyte of on-chip extended SRAM with full SEC-DED (single error correction/double error detection) ECC protection. This is specified in Table 1.1 (Outline of Specifications) and confirmed in the "Memory" section of the datasheet, enabling reliable storage of motion control algorithms and safety-critical variables without external memory.

Which industrial communication interfaces are supported by the R7S910017CBG#AC0?

The R7S910017CBG#AC0 supports EtherCAT (2-port slave), Ethernet MAC (1 port, IEEE 802.3, 10/100BASE-TX), dual CAN 2.0B (1 Mbps), 5× SCIFA, 2× I²C (400 kbps), 4× RSPI, SPIBSC, and optional encoder interfaces (EnDat 2.2, BiSS-C). These are fully documented in Table 1.1 and the "Communication function" section of the R01DS0228EJ0200 datasheet.
