Overview
R7S910026CBG#AC0 from Renesas Electronics is a 320-pin FBGA high-performance real-time MCU featuring dual Arm Cortex-R4 (600 MHz) and Cortex-M3 (150 MHz) cores, on-chip FPU, 1 Mbyte ECC-protected SRAM, EtherCAT slave controller (2-port), Ethernet MAC, dual CAN 2.0B interfaces, and industrial-grade operation up to +125°C junction temperature - deployed in servo drives and motion controllers requiring deterministic low-latency response.
For engineers reviewing the R7S910026CBG#AC0 datasheet, R7S910026CBG#AC0 pinout, R7S910026CBG#AC0 application, or R7S910026CBG#AC0 equivalent, this page delivers verified specifications, package mapping, functional alternatives, and design-critical timing/safety features specific to the R7S910026CBG#AC0 variant within the RZ/T1 Group.
Technical Context
The R7S910026CBG#AC0 integrates an Arm Cortex-R4 core operating at 600 MHz (996 DMIPS) with TCM (512 KB ATCM + 32 KB BTCM), instruction/data caches (8 KB each, ECC-protected), and a separate 150 MHz Cortex-M3 core for R-IN engine offload. It supports dual-core lockstep execution for safety-critical control loops and implements Arm CoreSight debugging via JTAG/SWD.
Its real-time subsystem includes EtherCAT slave IP (Beckhoff-certified), 2-channel encoder interface (EnDat 2.2/BiSS-C compliant), 33 timers (TPUa/MTU3a/GPTa), and event-link controller (ELC) enabling hardware-triggered peripheral coordination without CPU wake-up - essential for synchronized multi-axis motor control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time industrial control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R7S910013CBG#AC0 | Same 320-pin FBGA package, 600 MHz Cortex-R4, 1 Mbyte SRAM, but lacks EtherCAT slave controller and encoder interfaces. | Suitable for non-EtherCAT applications like standalone CAN-based drives or general-purpose industrial MCUs where protocol offload is handled externally. | Select when EtherCAT is not required and cost reduction is prioritized over integrated motion control features. |
| R7S910113CBG#AC0 | Includes optional security boot mode (AES-128 encrypted flash loading) and same 600 MHz/1 MB/EtherCAT/encoder feature set. | Required for systems needing secure firmware update, anti-cloning, or trusted boot in regulated medical or defense equipment. | Choose when cryptographic integrity and authenticated boot are mandatory - adds NDA-bound security IP not present in R7S910026CBG#AC0. |
