Product details

Overview

R9A07G084M08GBA#AC0 from Renesas Electronics is a high-end industrial MPU based on the Arm® Cortex®-R52 core (r1p3 revision), operating at 200/400 MHz with integrated FPU, NEON™, and 1.5 MB on-chip SRAM with ECC. It integrates dual CAN FD (ISO 11898-1), EtherCAT slave controller (2 ports), Ethernet MAC, USB 2.0 HS, xSPI, ΔΣ interface, and hardware security accelerators - designed for deterministic real-time control in industrial automation and motion systems.

For engineers reviewing the R9A07G084M08GBA#AC0 datasheet, R9A07G084M08GBA#AC0 pinout, R9A07G084M08GBA#AC0 application, or R9A07G084M08GBA#AC0 equivalent, key selection criteria include its 121-pin FBGA package, safety-isolated peripherals (GPT, SCI, IIC, SPI), 2-channel CAN FD support, 150/200 MHz system clock operation, and optional security boot with AES/RSA/ECDSA acceleration.

Technical Context

The R9A07G084M08GBA#AC0 implements a single-core Arm Cortex-R52 (r1p3) with Harvard architecture, 8-stage pipeline, TCM (128 KB ATCM + 128 KB BTCM), and dual-level MPU (EL2/EL1) for functional safety. Its memory subsystem includes 1.5 MB on-chip SRAM with SEC-DED ECC, supporting 150/200 MHz operation and direct connection to external SDRAM via configurable 8-/16-bit bus interfaces.

Real-time determinism is enabled by the Event Link Controller (ELC), which interlinks up to 217 event signals across modules - allowing timer-triggered A/D conversion, PWM waveform generation, and peripheral activation without CPU intervention, even during standby mode. Safety-critical functions are isolated via dedicated peripherals mapped under EL2 protection, including 4 GPT channels, 1 SCI, 1 IIC, 1 SPI, and CRC unit.

Equivalent & Alternatives

The following parts are listed as comparable options for similar industrial real-time MPU applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
R9A07G084M08GBG	225-pin FBGA, adds USB 2.0 HS, full 6-channel SCI, 3-port EtherCAT, 12-bit ADC (2 units), PHOSTIF - larger footprint and higher I/O count.	Required where USB host connectivity, full Ethernet switch (3-port), or on-chip ADC for analog sensor fusion is needed.	Select R9A07G084M08GBG when board space allows and additional interfaces justify the larger package and cost premium.
STM32H743VI	Arm Cortex-M7 @ 480 MHz, no EtherCAT or CAN FD, no hardware TFU or DSMIF, 1 MB Flash + 1 MB RAM, 100-pin LQFP - lacks industrial protocol offload and functional safety isolation.	Suitable for non-safety-rated HMI or gateway tasks but cannot replace R9A07G084M08GBA#AC0 in SIL3 motion control or EtherCAT slave roles.	Choose STM32H743VI only for cost-sensitive, non-safety applications lacking CAN FD/EtherCAT timing requirements.

Compared with R9A07G084M08GBG, the R9A07G084M08GBA#AC0 trades USB, full ADC, and extra EtherCAT ports for compact 121-pin packaging and lower BOM cost - while retaining identical safety isolation, TFU, and CAN FD performance. Versus STM32H743VI, it delivers certified functional safety, deterministic protocol offload, and hardware-accelerated signal processing unattainable in Cortex-M7-class devices.

FAQ

What is the maximum operating frequency of the Arm Cortex-R52 core in the R9A07G084M08GBA#AC0?

The R9A07G084M08GBA#AC0 features an Arm Cortex-R52 core operating at up to 400 MHz when paired with a 200 MHz system clock, or 300 MHz with a 150 MHz system clock. This dual-frequency capability enables dynamic performance scaling for real-time industrial workloads while maintaining strict timing predictability required for SIL3 applications. The R9A07G084M08GBA#AC0 achieves this through its on-chip PLL and clock generation circuit with configurable dividers and multiplexers.

Does the R9A07G084M08GBA#AC0 support EtherCAT slave functionality, and how many ports are available?

Yes, the R9A07G084M08GBA#AC0 integrates an EtherCAT slave controller (ESC) IP core licensed from Beckhoff Automation GmbH, supporting 2 physical EtherCAT ports in its 121-pin FBGA configuration. This matches the ESC implementation in the 225-pin variant but omits the third port to reduce pin count. The R9A07G084M08GBA#AC0 maintains full compliance with EtherCAT protocol specifications including PRP, DLR, and time-synchronized I/O mapping.

What safety certifications or functional safety features does the R9A07G084M08GBA#AC0 provide?

The R9A07G084M08GBA#AC0 includes hardware-enforced functional safety features aligned with IEC 61508 SIL3 and ISO 13849 PL e requirements: dual-stage MPU (EL2/EL1), register write protection, clock monitor circuit (CLMA), CRC calculators (2 channels), and safety-isolated peripherals (GPT, SCI, IIC, SPI, RTC). These features are implemented in silicon and documented in Renesas' Functional Safety Manual R01UM0575EJ0100. The R9A07G084M08GBA#AC0 itself is not pre-certified, but provides the foundational hardware for certified system development.

Can the R9A07G084M08GBA#AC0 execute secure boot, and what cryptographic algorithms are accelerated?

Yes, the R9A07G084M08GBA#AC0 supports secure boot with hardware-accelerated cryptography including AES-128/192/256 (CBC/ECB/CTR/GCM/XTS), RSA-1024/2048/3072, ECDSA with NIST P-256, SHA-1/SHA-2, HMAC, CMAC, and GMAC. Boot authentication uses one-time programmable (OTP) memory to store immutable root keys, and the TRNG provides entropy for key generation. Security is optional and enabled via fuse settings - the R9A07G084M08GBA#AC0 part number denotes the security-enabled variant.

What is the difference between the R9A07G084M08GBA#AC0 and R9A07G084M08GBG package variants?

The R9A07G084M08GBA#AC0 uses a 121-pin FBGA (10 × 10 mm), while the R9A07G084M08GBG uses a 225-pin FBGA (13 × 13 mm). Key functional differences include omission of USB 2.0 HS, reduced EtherCAT ports (2 vs. 3), 5-channel SCI (vs. 6), single xSPI channel (vs. 2), and no on-chip 12-bit ADC in the R9A07G084M08GBA#AC0. Both share identical Cortex-R52 core, safety isolation, TFU, DSMIF, and CAN FD capabilities - making the R9A07G084M08GBA#AC0 ideal for space-constrained industrial designs.
