FAQ

What is the maximum operating frequency of the R9A07G084M08GBG#AC0 CPU core?

The R9A07G084M08GBG#AC0 CPU core operates at up to 400 MHz when paired with a 200 MHz system clock, or 300 MHz with a 150 MHz system clock. This frequency is achieved by the single-core Arm Cortex-R52 (revision r1p3) with Harvard architecture and 8-stage pipeline. The R9A07G084M08GBG#AC0 datasheet confirms these values in Table 1.1 under "Operating frequency" and specifies that both modes include FPU and NEON support. Thermal design must accommodate T_j = −40 to +125°C operation.

Does the R9A07G084M08GBG#AC0 support EtherCAT slave functionality, and how many ports are available?

Yes, the R9A07G084M08GBG#AC0 integrates an EtherCAT slave controller (ESC) IP core licensed from Beckhoff Automation GmbH, supporting three physical ports. This is explicitly stated in Table 1.8 and Figure 1.1 of the R01DS0397EJ0140 datasheet. The R9A07G084M08GBG#AC0 uses external RGMII converters for PHY interfacing and supports IEEE 1588-2008 time-stamping essential for synchronized distributed motion control. All three ports are fully functional in the 225-pin FBGA package.

What security features are implemented in the R9A07G084M08GBG#AC0?

The R9A07G084M08GBG#AC0 includes optional security features: secure boot with encryption, JTAG authentication, SCI/USB boot disable, TRNG, and cryptographic accelerators for AES-128/192/256, ECC-256, RSA-1024/2048/3072, SHA-1/2, HMAC/CMAC/GMAC, and ECDSA. These are documented in Table 1.12 and confirmed in Table 1.17, which lists "Available" for security in the R9A07G084M08GBG#AC0 part number. The R9A07G084M08GBG#AC0 also includes one-time programmable (OTP) memory for storing unique IDs and authentication settings.

What is the package type and pin count of the R9A07G084M08GBG#AC0?

The R9A07G084M08GBG#AC0 uses a 225-pin Fine-Pitch Ball Grid Array (FBGA) package measuring 13 mm × 13 mm with 0.8 mm pitch. This is specified in Table 1.15 ("Packages") and Table 1.17 ("Product Lineup") of the R01DS0397EJ0140 datasheet. The package supports 134 I/O pins, 1 input-only pin, and 135 pull-up/pull-down resistors. It is RoHS-compliant and rated for junction temperature range T_j = −40 to +125°C - matching the thermal requirements of industrial motor drive and PLC applications.

How does the R9A07G084M08GBG#AC0 support functional safety compliance?

The R9A07G084M08GBG#AC0 supports functional safety through hardware-enforced isolation: dual-stage MPU (EL2/EL1), register write protection, clock monitor circuit (CLMA), CRC calculators (2 channels), and dedicated safety peripherals (GPT, SCI, IIC, SPI, CRC, RTC) mapped independently in memory space. These features are detailed in Tables 1.11 and 1.16 and enable separation of safety-critical tasks from standard firmware. The R9A07G084M08GBG#AC0 is designed to assist in achieving IEC 61508 SIL2 and ISO 13849 PLd certification when used with appropriate software and system-level measures.
