For engineers reviewing the R9A07G074M04GBG datasheet, R9A07G074M04GBG pinout, R9A07G074M04GBG application, or R9A07G074M04GBG equivalent, this device supports deterministic low-latency execution in safety-critical motion control, industrial Ethernet gateway, and multi-axis servo drive designs requiring hardware-accelerated trigonometric computation (TFU), ΔΣ interface support, and functional safety peripherals.

Technical Context

The R9A07G074M04GBG implements a single-core Arm Cortex-R52 (r1p2) with Harvard architecture, 8-stage pipeline, dual 16 KB instruction/data caches with ECC, and 512 KB/64 KB ATCM/BTCM with ECC-enabling deterministic interrupt latency under 100 ns. It integrates a dedicated Event Link Controller (ELC) enabling module-triggered operation without CPU intervention, critical for synchronized PWM generation and A/D conversion triggering.

Its industrial interface subsystem includes two independent DSMIF units supporting up to six external ΔΣ modulators, a Trigonometric Function Unit (TFU) for simultaneous sine/cosine and arctangent/hypot_k calculation, and isolated safety peripherals (4-channel GPT, 1-channel SCI/IIC/SPI, CRC, RTC) mapped behind EL2 MPU for ASIL-B compliance pathways.

FAQ

What is the maximum operating frequency of the R9A07G074M04GBG CPU core?

The R9A07G074M04GBG features a single Arm Cortex-R52 core capable of operating at up to 800 MHz when paired with a 200 MHz system clock. This frequency is confirmed in the official datasheet (R01DS0409EJ0130 Rev.1.30) and enables sub-microsecond interrupt response times required for hard real-time industrial control loops. The R9A07G074M04GBG supports multiple clock configurations including 150/300/600 MHz modes for power-optimized operation.

Does the R9A07G074M04GBG support EtherCAT slave functionality?

Yes, the R9A07G074M04GBG integrates a Beckhoff Automation–licensed EtherCAT Slave Controller (ESC) with three physical ports (MII interface), enabling it to operate as a full-featured EtherCAT slave device. This is explicitly documented in Table 1.8 of the R01DS0409EJ0130 datasheet. The R9A07G074M04GBG does not include the GMAC Ethernet MAC function per Note 2, but relies on the ESC for protocol handling and timing-critical frame processing.

What encoder interface protocols are supported by the R9A07G074M04GBG?

The R9A07G074M04GBG supports four industrial encoder protocols across two independent channels each: EnDat 2.2, BiSS-C, A-format, and HIPERFACE DSL. This is specified in Table 1.10 and Figure 1.1 of the R01DS0409EJ0130 datasheet. Additionally, it includes one ENCOUT channel for incremental encoder output. These interfaces are hardware-accelerated and operate independently of the CPU, ensuring deterministic position feedback acquisition.

How much on-chip SRAM does the R9A07G074M04GBG provide, and what protection features does it include?

The R9A07G074M04GBG includes 1.0 MB of on-chip SRAM implemented as two 512 KB banks, both protected with SEC-DED (single error correction/double error detection) ECC. This is detailed in Table 1.2 and Section 1.1 of the R01DS0409EJ0130 datasheet. The SRAM operates at 150 MHz or 200 MHz and supports error injection for diagnostic testing - a requirement for IEC 61508 SIL2 compliance in safety-critical applications.

What is the package type and pin count of the R9A07G074M04GBG?

The R9A07G074M04GBG is housed in a 196-pin Fine-Pitch Ball Grid Array (FBGA) package measuring 12 mm × 12 mm with 0.8 mm ball pitch. This is confirmed in Table 1.15 (Product Lineup) and Table 1.14 (Others) of the R01DS0409EJ0130 datasheet. The package supports 110 I/O pins, one dedicated input pin, and 111 programmable pull-up/pull-down resistors - optimized for high-density industrial PCB layouts.
