Renesas R9A07G074M05GBG#AC0

Overview

R9A07G074M05GBG from Renesas Electronics is a high-performance Arm® Cortex®-R52-based MPU targeting real-time industrial motion control, supporting 200/400/800 MHz operation, 1.0 MB on-chip SRAM with ECC, dual classical CAN (ISO 11898-1), and integrated EtherCAT slave controller (3-port). It delivers deterministic low-latency response for servo drives and PLCs.

For engineers reviewing the R9A07G074M05GBG datasheet, R9A07G074M05GBG pinout, R9A07G074M05GBG application, or R9A07G074M05GBG equivalent, key selection considerations include its 196-pin FBGA package, absence of CAN FD support, presence of EnDat 2.2/BiSS-C encoder interfaces, and lack of built-in Ethernet MAC - requiring external PHY for full network connectivity.

Technical Context

The R9A07G074M05GBG implements a single-core Arm Cortex-R52 (r1p2) with TCM (512 KB ATCM + 64 KB BTCM), dual 16 KB instruction/data caches with ECC, and Harvard architecture with 8-stage pipeline. It supports Arm v8-R, Thumb/Thumb-2, and Little-endian data/instruction layout.

Its safety architecture includes dual-stage MPU (EL2/EL1), register write protection, clock monitor (CLMA), CRC calculators (2 channels), and isolated safety peripherals (GPT×4, SCI×1, IIC×1, SPI×1, RTC×1). Security features include AES-128/192/256, ECC-256, RSA-1024/2048/3072, SHA-1/SHA-2, and TRNG - though JTAG authentication is enabled via MDD pin configuration.

FAQ

Does R9A07G074M05GBG support CAN FD?

No, R9A07G074M05GBG supports only classical CAN (ISO 11898-1) at up to 1 Mbps. It does not implement CAN FD features such as flexible data-rate or extended payload. For CAN FD capability, consider R9A07G074M08GBG or R9A07G074M04GBG. The R9A07G074M05GBG datasheet explicitly confirms classical CAN-only operation in Table 1.16.

What is the maximum operating frequency of R9A07G074M05GBG?

The R9A07G074M05GBG operates at 200 MHz, 400 MHz, or 800 MHz depending on system clock configuration (150 MHz or 200 MHz base). Its Cortex-R52 core runs at these frequencies with full cache and TCM support. The actual achievable frequency depends on voltage scaling and thermal conditions within the −40°C to +125°C junction range.

Does R9A07G074M05GBG include an integrated Ethernet MAC?

No, R9A07G074M05GBG does not integrate an Ethernet MAC. It includes only the EtherCAT slave controller (ESC) with three MII ports. To implement standard Ethernet connectivity, an external Ethernet PHY and MAC (e.g., via GMAC in companion devices) must be used. This is confirmed in Note 2 of Table 1.8 and Figure 1.1 block diagram.

How many encoder interface protocols does R9A07G074M05GBG support?

R9A07G074M05GBG supports four encoder protocols across two independent channels each: EnDat 2.2, BiSS-C, A-format, and HIPERFACE DSL - totaling eight logical interfaces. Additionally, it includes one ENCOUT channel for incremental encoder output. All are implemented in dedicated hardware subsystems with no CPU overhead.

What safety certifications does R9A07G074M05GBG target?

R9A07G074M05GBG targets IEC 61508 SIL 3 and ISO 13849 PL e through its dual-stage MPU, register write protection, CLMA clock monitor, CRC calculators, and isolated safety peripherals (GPT×4, SCI×1, etc.). Its safety architecture is documented in Section 1.11 and validated in Renesas' Functional Safety Manual R01UM0572EJ0100, which applies to the RZ/T2L family including R9A07G074M05GBG.

Is JTAG authentication enabled by default on R9A07G074M05GBG?

JTAG authentication is not enabled by default on R9A07G074M05GBG. It is controlled by the MDD pin: driving MDD high at reset enables hash-based JTAG authentication, while pulling it low disables it. This configuration is fixed at boot and cannot be changed dynamically. The feature is part of the optional security suite described in Table 1.12.
