Renesas R9A07G075M24GBG#AC0

Overview

R9A07G075M24GBG#AC0 from Renesas Electronics is a dual-core Arm® Cortex®-R52 high-end real-time MPU targeting industrial motion control and EtherCAT slave applications. It operates at 200/400/800 MHz, integrates 2.0 MB on-chip SRAM with ECC, dual CAN-FD channels (ISO 11898-1), Ethernet MAC, and hardware accelerators for ΔΣ modulation and trigonometric functions - deployed in servo drives and PLCs requiring deterministic low-latency response.

For engineers reviewing the R9A07G075M24GBG#AC0 datasheet, R9A07G075M24GBG#AC0 pinout, R9A07G075M24GBG#AC0 application, or R9A07G075M24GBG#AC0 equivalent, key selection criteria include dual Cortex-R52 lock-step readiness (though DCLS not supported), CAN-FD data bit rate up to 8 Mbps, 2.0 MB ECC-protected SRAM, EtherCAT slave controller (3-port MII), and 320-pin FBGA package with 193 I/O pins.

Technical Context

The R9A07G075M24GBG#AC0 implements two Arm Cortex-R52 cores (r1p2) in asymmetric dual-core configuration: CPU0 includes 512 KB ATCM + 64 KB BTCM and full cache (16 KB I/D), while CPU1 provides 32 KB I/D cache only - no TCM. It uses Arm v8-R architecture with Little-endian data/instruction layout, Harvard pipeline, and dual-stage MPU (EL2/EL1) for safety-critical partitioning.

Real-time determinism is enforced via Event Link Controller (ELC) enabling module-triggered operation without CPU wake-up, MTU3/GPT timers with dead-time compensation and PWM synchronization, and isolated safety peripherals (4 GPT, 1 SCI, 1 IIC, CRC, RTC) mapped separately under EL2 protection. Security features include AES-128/192/256, ECDSA-P256, TRNG, and JTAG authentication - though security boot is disabled per part number suffix "M24".

FAQ

Does R9A07G075M24GBG#AC0 support dual-core lock-step (DCLS) operation?

No, R9A07G075M24GBG#AC0 explicitly does not support Dual Core Lock Step (DCLS) per datasheet Section 1.1 Table 1.1. It implements asymmetric dual Cortex-R52 cores: CPU0 with full TCM and cache for real-time tasks, and CPU1 cache-only for background services. Safety-critical redundancy must be implemented via software partitioning and EL2 MPU isolation - not hardware lock-step.

What is the maximum CAN-FD data bit rate supported by R9A07G075M24GBG#AC0?

R9A07G075M24GBG#AC0 supports CAN-FD data bit rates up to 8 Mbps per channel, compliant with ISO 11898-1:2015. This is confirmed in Table 1.8 (CANFD module) and applies to both of its two CAN-FD channels - enabling high-bandwidth feedback from multi-turn absolute encoders or distributed I/O nodes in time-critical motion systems.

Is security functionality enabled on R9A07G075M24GBG#AC0?

No, security features including secure boot, cryptographic accelerators (AES/ECDSA/SHA), and JTAG authentication are disabled on R9A07G075M24GBG#AC0, as indicated by the "M24" suffix in the part number (per Table 1.16). For security-enabled variants, use R9A07G075M28GBG or R9A07G075M26GBG with appropriate boot configuration.

Which package and pin count does R9A07G075M24GBG#AC0 use?

R9A07G075M24GBG#AC0 uses a 320-pin Fine-Pitch Ball Grid Array (FBGA) package measuring 17 mm × 17 mm with 0.8 mm pitch and an exposed thermal pad. It provides 193 configurable I/O pins, as specified in Table 1.5 and Figure 1.1 of the R01DS0383EJ0130 datasheet - supporting dense peripheral routing for motor control and industrial networking.

Does R9A07G075M24GBG#AC0 include EtherCAT slave functionality?

Yes, R9A07G075M24GBG#AC0 integrates a Beckhoff-certified EtherCAT Slave Controller (ESC) with 3-port MII interface, as documented in Table 1.8 and Section 1.2. This enables direct implementation of EtherCAT slave nodes in servo drives and I/O terminals without external ASICs - supporting full EtherCAT protocol processing including distributed clocks and process data exchange.
