Renesas R9A07G074M01GBG#AC0

Overview

R9A07G074M01GBG from Renesas Electronics is a high-performance Arm Cortex-R52-based MPU targeting real-time industrial motion control systems. It integrates a single 800 MHz Cortex-R52 core with FPU and NEON, 1.0 MB on-chip SRAM with ECC, dual-channel Classical CAN (1 Mbps), EtherCAT slave controller (3-port), Ethernet MAC, USB 2.0 HS, xSPI, ΔΣ interface, and EnDat 2.2/BiSS-C encoder interfaces - all operating across −40 to +125°C junction temperature.

For engineers reviewing the R9A07G074M01GBG datasheet, R9A07G074M01GBG pinout, R9A07G074M01GBG application, or R9A07G074M01GBG equivalent, key selection considerations include its Classical CAN-only interface (no CAN FD), absence of hardware security accelerators and EtherCAT support in this variant, and its 196-pin FBGA package optimized for servo drive and PLC edge node designs requiring deterministic low-latency I/O and safety-aware peripheral partitioning.

Technical Context

The R9A07G074M01GBG implements a single Arm Cortex-R52 (r1p2) core executing at up to 800 MHz with Harvard architecture, 16 KB instruction/data caches (ECC-protected), and 512 KB/64 KB ATCM/BTCM (ECC). Its memory subsystem includes 1.0 MB on-chip SRAM (ECC, 150/200 MHz), one-time programmable memory for boot mode and unique ID, and a bus state controller supporting four CS areas with 8-/16-bit external bus interface up to 100 MHz.

Real-time capability is reinforced by an event link controller (ELC) enabling module-triggered operation without CPU intervention, dual DMAC units (16 channels each), 35+ timers including MTU3 (9 ch), GPT (18 ch), CMT/CMTW, and safety-dedicated peripherals (4 GPT, 1 SCI, 1 IIC, 1 SPI, CRC, RTC) isolated via EL2 MPU. The device lacks hardware cryptographic accelerators and EtherCAT IP - confirmed in Table 1.16 as "Not available" for this part number.

FAQ

What is the maximum operating frequency of the R9A07G074M01GBG CPU core?

The R9A07G074M01GBG features a single Arm Cortex-R52 core operating at up to 800 MHz when paired with a 200 MHz system clock. This frequency is confirmed in Table 1.1 of the R01DS0409EJ0130 datasheet and applies specifically to the R9A07G074M01GBG variant. Lower frequencies (200/400 MHz) are also supported for thermal or power-constrained deployments. The core uses a Harvard architecture with 8-stage pipeline and ECC-protected 16 KB instruction/data caches.

Does the R9A07G074M01GBG support CAN FD or only Classical CAN?

The R9A07G074M01GBG supports Classical CAN only, with a maximum bit rate of 1 Mbps per channel, and does not implement CAN FD functionality. This is explicitly stated in Table 1.16 of the R01DS0409EJ0130 datasheet, which lists "Classical CAN" for this part number and marks CAN-FD as unavailable. The device includes two CAN channels compliant with ISO 11898-1 (2015), suitable for CANopen and DeviceNet networks but not for higher-bandwidth FD frame payloads.

Is EtherCAT supported on the R9A07G074M01GBG?

No, EtherCAT is not supported on the R9A07G074M01GBG. Table 1.16 confirms "Not available" for EtherCAT in this variant. While the RZ/T2L family includes an EtherCAT slave controller (ESC) IP core licensed from Beckhoff, it is excluded from the R9A07G074M01GBG silicon configuration. The device retains the Ethernet MAC (GMAC) for standard TCP/IP or TSN-based protocols but lacks the dedicated ESC hardware required for EtherCAT frame processing and synchronization.

What security features are included in the R9A07G074M01GBG?

The R9A07G074M01GBG includes JTAG authentication (enabled via MDD pin) and basic secure boot functionality but omits all hardware cryptographic accelerators - no AES, ECC, RSA, SHA, or TRNG engines are present. Table 1.12 and Table 1.16 confirm "Not available" for security accelerators and TRNG in this variant. Security relies on software-implemented cryptography and external secure elements, making it suitable for applications where physical debug access control suffices but not for high-assurance encrypted communications or key generation.

What is the on-chip SRAM capacity and ECC implementation for R9A07G074M01GBG?

The R9A07G074M01GBG integrates 1.0 MB of on-chip SRAM with full SEC-DED (single error correction/double error detection) ECC protection, organized as two 512 KB banks. This is specified in Table 1.2 and confirmed across multiple sections of the R01DS0409EJ0130 datasheet. The SRAM operates at 150 MHz or 200 MHz depending on system clock configuration and supports error injection for test purposes - a critical feature for functional safety applications requiring ASIL B/D or SIL2 compliance.
