Renesas R7S910015CBG#AC0

Overview

R7S910015CBG#AC0 from Renesas Electronics is a high-performance real-time industrial MCU integrating an Arm Cortex-R4 core (450 MHz, 747 DMIPS) 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, EtherCAT slave controller (2-port), and Ethernet MAC - deployed in servo drives, motion controllers, and industrial PLCs requiring deterministic low-latency control.

For engineers reviewing the R7S910015CBG#AC0 datasheet, R7S910015CBG#AC0 pinout, R7S910015CBG#AC0 application, or R7S910015CBG#AC0 equivalent, key selection criteria include confirmed R-IN engine integration, 450 MHz Cortex-R4 operation with TCM/ECC memory, dual-CAN + EtherCAT + Ethernet MAC concurrency, 320-pin FBGA package (PRBG0320GA-A), and -40°C to +125°C junction temperature rating.

Technical Context

The R7S910015CBG#AC0 implements a dual-core heterogeneous architecture: the Cortex-R4 handles high-speed real-time motion control with TCM (512 KB ATCM + 32 KB BTCM), instruction/data caches (8 KB each, ECC-protected), and FPU supporting single/double-precision operations; the Cortex-M3 (r2p1, 150 MHz) runs the R-IN engine firmware for industrial protocol offload and network stack processing.

Hardware acceleration includes event link controller (ELC) enabling CPU-sleep module chaining, dedicated port output enable (POE3) for safe PWM shutdown, and integrated safety modules (CRC, IWDTa, CLMA, ECM) meeting IEC 61508 SIL2 requirements - all operating under dual-voltage supply (1.2 V core, 3.3 V I/O) and qualified for Tj = -40°C to +125°C.

FAQ

What is the maximum operating frequency and DMIPS rating of the R7S910015CBG#AC0?

The R7S910015CBG#AC0 operates at a maximum Cortex-R4 frequency of 450 MHz, delivering 747 DMIPS. Its integrated Cortex-M3 runs at 150 MHz to support the R-IN engine. These values are confirmed in the official Renesas datasheet R01DS0228EJ0200 Rev.2.00, Table 1.1. The R7S910015CBG#AC0 does not support the 600 MHz variant found in other RZ/T1 family members like R7S910013CBG.

Does the R7S910015CBG#AC0 include EtherCAT slave functionality, and how many ports are supported?

Yes, the R7S910015CBG#AC0 integrates a Beckhoff-licensed EtherCAT Slave Controller (ECATC) supporting two physical ports, as documented in Table 1.2 and Section 1.1 of the R01DS0228EJ0200 datasheet. This is a standard feature for all 320-pin RZ/T1 devices with R-IN engine, including R7S910015CBG#AC0 - no optional configuration or license activation is required.

What memory resources are available on-chip for the R7S910015CBG#AC0?

The R7S910015CBG#AC0 provides 1 Mbyte of on-chip extended SRAM with SEC-DED ECC protection, plus tightly coupled memory (512 KB ATCM and 32 KB BTCM, both ECC-protected), and separate 8 KB instruction and 8 KB data caches (ECC-enabled). This memory architecture is explicitly assigned to the R-IN engine in Table 1.3 of the R01DS0228EJ0200 datasheet.

Which industrial communication interfaces are integrated into the R7S910015CBG#AC0?

The R7S910015CBG#AC0 integrates dual CAN 2.0B controllers (up to 1 Mbps), a 10/100BASE-T Ethernet MAC (MII/RMII), a 2-port EtherCAT slave controller, USB 2.0 HS host/function, 5-channel SCIFA, 2-channel I²C, 4-channel RSPIa, SPIBSC, and serial sound interface (SSI). All are confirmed in Table 1.1 and Table 1.2 of the R01DS0228EJ0200 datasheet.

Is the R7S910015CBG#AC0 qualified for extended temperature operation, and what is its junction temperature range?

Yes, the R7S910015CBG#AC0 is qualified for industrial-grade operation with a junction temperature range of Tj = -40°C to +125°C, as specified in the "Operating temperature" section on page 8 of the R01DS0228EJ0200 datasheet. This rating applies to all 320-pin FBGA variants, including R7S910015CBG#AC0, and is validated across the full voltage and frequency operating conditions.
