Renesas R7S910002CBG#AC0

Overview

R7S910002CBG#AC0 from Renesas Electronics is a 320-pin FBGA high-performance MCU featuring an Arm® Cortex-R4 processor (r1p4) operating at up to 450 MHz, delivering 747 DMIPS, with 8 KB instruction/data cache (ECC), 512 KB ATCM + 32 KB BTCM (ECC), and integrated Ethernet MAC for industrial real-time motion control systems.

For engineers reviewing the R7S910002CBG#AC0 datasheet, R7S910002CBG#AC0 pinout, R7S910002CBG#AC0 application, or R7S910002CBG#AC0 equivalent, this page delivers verified functional scope, package-specific peripheral channel counts, safety features including CRC and error control module (ECM), and confirmed absence of R-IN engine and EtherCAT in this variant.

Technical Context

This device implements a dual-core architecture with a primary Cortex-R4 core (450 MHz, Harvard, 8-stage pipeline) supporting Arm v7-R, Thumb/Thumb-2, and FPU operations - but excludes the optional Cortex-M3 R-IN engine per Table 1.3. It integrates tightly coupled memory with ECC, dual DMAC units (32 channels total), and event link controller (ELC) enabling low-latency inter-module triggering without CPU wake-up.

Peripheral configuration is package- and variant-specific: R7S910002CBG#AC0 uses the 320-pin PRBG0320GA-A FBGA, enabling full 12-channel TPUa, 9-channel MTU3a, 4-channel GPTa, 2-channel CAN, 5-channel SCIFA, and dual 12-bit A/D converters (8+16 channels), while omitting encoder interfaces, secure boot, and EtherCAT slave controller as confirmed in Table 1.3.

FAQ

Does R7S910002CBG#AC0 include the R-IN engine (Cortex-M3 core)?

No. According to Table 1.3 in the R01DS0228EJ0200 datasheet, R7S910002CBG#AC0 is explicitly listed as "R-IN Engine Not-Incorporated". It contains only the Arm Cortex-R4 core and does not include the optional Cortex-M3 co-processor or its associated peripherals such as the R-IN engine's dedicated timers or communication accelerators. The R7S910015CBG#AC0 variant is required for R-IN engine functionality.

What is the maximum operating frequency and DMIPS rating of R7S910002CBG#AC0?

R7S910002CBG#AC0 operates at a maximum frequency of 450 MHz and delivers 747 DMIPS, as confirmed in Table 1.3 and Section 1.1 of the datasheet. This performance level is achieved using the Arm Cortex-R4 core (revision r1p4) with 8 KB instruction and data caches (both with ECC), Harvard architecture, and 8-stage pipeline - optimized for deterministic real-time execution in industrial control applications.

Is EtherCAT supported on R7S910002CBG#AC0?

No. R7S910002CBG#AC0 does not include the EtherCAT Slave Controller (ECATC). Table 1.3 states "Not supported" for EtherCAT under the 176-pin row and omits ECATC entirely for all 320-pin variants except those explicitly marked with "EtherCAT" in the Optional Function column (e.g., R7S910011CBG#AC0). This part supports only the standard Ethernet MAC (ETHERC) with MII/RMII interface and optional Ethernet switch functionality.

What package type and pin count does R7S910002CBG#AC0 use?

R7S910002CBG#AC0 uses the PRBG0320GA-A package: a 320-pin Fine-Pitch Ball Grid Array (FBGA) measuring 17 mm × 17 mm with 0.8 mm ball pitch. This package supports the full peripheral complement for the RZ/T1 Group, including 12-channel TPUa, 9-channel MTU3a, dual CAN, and dual 12-bit A/D converters - as verified in Table 1.2 and the package dimension table on page 8 of R01DS0228EJ0200.

Does R7S910002CBG#AC0 include on-chip extended SRAM?

No. R7S910002CBG#AC0 has zero on-chip extended SRAM, as indicated by "Not supported" in the "On-Chip Extended SRAM Capacity" column for this part number in Table 1.3. In contrast, variants like R7S910006CBG#AC0 and R7S910007CBG#AC0 provide up to 1 Mbyte of on-chip extended SRAM with ECC. Designers must plan for external memory interfaces (e.g., SDRAM or SRAM via BSC) when using R7S910002CBG#AC0.

What safety features are implemented in R7S910002CBG#AC0?

R7S910002CBG#AC0 includes register write protection, CRC calculator (supporting four polynomials), input clock oscillation stop detection, clock monitor circuit (CLMA), data operation circuit (DOC), and error control module (ECM) - all documented in Sections 1.1 and 1.2 of R01DS0228EJ0200. The ECM can generate interrupts, internal resets, or external error signals upon detection of faults from any module, enabling compliance with IEC 61508 SIL 2/3 system-level safety architectures.
