Product details
Overview
R9A07G075M28GBA#AC0 from Renesas Electronics is a dual-core Arm® Cortex®-R52 high-integrity MPU for real-time industrial motion control, featuring 800 MHz CPU frequency, 2.0 MB on-chip SRAM with ECC, dual CAN FD (ISO 11898-1), EtherCAT slave controller (3 ports), and integrated ΔΣ interface for precision motor feedback acquisition.
For engineers reviewing the R9A07G075M28GBA#AC0 datasheet, R9A07G075M28GBA#AC0 pinout, R9A07G075M28GBA#AC0 application, or R9A07G075M28GBA#AC0 equivalent, this device is selected for deterministic servo drive firmware, safety-critical PLC I/O processing, and time-sensitive EtherCAT slave node implementation where dual-lockstep alternatives are not required but functional safety support (MPU, CRC, CLMA) and hardware-accelerated trigonometric/encoder functions are essential.
Technical Context
The R9A07G075M28GBA#AC0 implements two Arm Cortex-R52 cores (r1p2) in asymmetric dual-CPU configuration-CPU0 with 512 KB ATCM + 64 KB BTCM and full cache/ECC, CPU1 with 32 KB instruction/data caches only-targeting real-time control partitioning. Its memory subsystem delivers 2.0 MB of ECC-protected SRAM at 200 MHz, supporting deterministic access for safety-critical code and data.
Hardware acceleration includes a dedicated Trigonometric Function Unit (TFU) for simultaneous sine/cosine and arctangent/hypotk computation, dual DSMIF units (6 ΔΣ channels total), and EnDat 2.2/BiSS-C encoder interfaces-enabling direct connection to high-resolution position sensors without external FPGA logic. The ELC (Event Link Controller) allows peripheral-triggered operation (e.g., timer start on encoder Z-phase pulse) while CPUs remain in standby.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Dual Arm Cortex-R52 (r1p2); CPU0 active with TCM/cache, CPU1 cache-only-enables asymmetric real-time task partitioning. |
| CPU Frequency | 800 MHz (200 MHz system clock ×4); enables sub-μs interrupt latency for servo loop closure. |
| On-chip SRAM | 2.0 MB with SEC-DED ECC; sufficient for dual-core firmware, safety stacks, and real-time buffer storage without external RAM. |
| CAN/CAN FD | 2 channels compliant with ISO 11898-1; supports 8 Mbps data bit rate in FD mode for high-bandwidth actuator command streaming. |
| EtherCAT Interface | ESC with 3 ports (MII); integrates Beckhoff-certified slave IP for deterministic <1 μs jitter in distributed clock synchronization. |
| Encoder Support | EnDat 2.2, BiSS-C, HIPERFACE DSL; eliminates need for external protocol translators in servo motor feedback paths. |
| ΔΣ Interface | 2 units × 3 channels (6 total); directly acquires high-resolution current/voltage sensor data with Sinc filter programmability. |
| Operating Temp | Tj = −40 to +125°C; qualified for under-hood industrial drives and factory-floor automation equipment. |
Pinout & Package
Package: 225-pin FBGA (13 mm × 13 mm, 0.8 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (1.1 V) | Core power supply | Must be filtered with ≥22 μF ceramic capacitor per power domain; voltage tolerance ±3% for stable 800 MHz operation. |
| VCC18 (1.8 V) | PLL/USB/ADC supply | Shared rail for high-speed analog/digital blocks; requires separate low-noise LDO to prevent ADC quantization noise coupling. |
| VCC33 (3.3 V) | I/O and USB PHY supply | Drives all GPIO, SCI, SPI, and USB D+/D−; must meet USB 2.0 HS eye diagram requirements via proper decoupling. |
| CLKIN | External clock input | Accepts 25 MHz crystal or oscillator; feeds PLL for CPU/system clock generation; requires 10 kΩ pull-down for unused state. |
| ETH_MDC/MDIO | PHY management interface | Configures external Ethernet PHY registers during boot; shared with GPIO function if ETHSW disabled. |
| CANFD0_TX/RX | CAN FD channel 0 differential pair | Requires 120 Ω termination at far end; supports 1–8 Mbps data phase with automatic bit-rate switching. |
| ENCA_U/V/W | ΔΣ modulator inputs | Direct connection to 3-phase current sense modulators; internal Sinc filter reduces need for external digital filtering logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar real-time industrial MPU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R9A07G075M26GBA#AC0 | Same package and dual-core architecture, but Classical CAN (1 Mbps only) instead of CAN FD; no EtherCAT slave controller. | Suitable for legacy CAN-based motion networks without FD bandwidth or EtherCAT synchronization needs. | Select when cost reduction is prioritized over 8 Mbps CAN FD data throughput and deterministic EtherCAT timing. |
| R9A07G075M24GBA#AC0 | Identical dual-core, CAN FD, and package-but lacks Ethernet MAC/switch/ESC functionality; retains xSPI, USB, and security accelerators. | Targeted at isolated motor control nodes where Ethernet connectivity is handled by external master, not local slave processing. | Choose when Ethernet offload to companion SoC is acceptable and board space/power budget must exclude integrated PHY/switch. |
Compared with R9A07G075M26GBA#AC0 and R9A07G075M24GBA#AC0, the R9A07G075M28GBA#AC0 uniquely combines CAN FD bandwidth, EtherCAT slave timing determinism, and dual-core real-time partitioning in a 225-pin footprint-making it the only option among these three for compact, self-contained EtherCAT servo drives requiring both high-speed fieldbus and motor feedback processing.
