Product details
Overview
R9A07G084M04GBA#AC0 from Renesas Electronics is a high-end 32-bit Arm® Cortex®-R52 microprocessor unit (MPU) operating at 200/400 MHz, featuring on-chip FPU and NEON™, 1.5 MB ECC-protected SRAM, dual CAN FD interfaces (ISO 11898-1), EtherCAT slave controller (3 ports), and integrated security accelerators (AES-256, ECC-256, TRNG). It targets real-time industrial automation controllers requiring deterministic Ethernet timing, motor control with PWM and ΔΣ interface support, and functional safety-compliant I/O subsystems.
For engineers reviewing the R9A07G084M04GBA#AC0 datasheet, R9A07G084M04GBA#AC0 pinout, R9A07G084M04GBA#AC0 application, or R9A07G084M04GBA#AC0 equivalent, this page delivers verified technical context for safety-critical motion control, EtherCAT-enabled PLCs, and secure industrial edge gateways - including confirmed Tj = −40 to +125°C operation, 121-pin FBGA package mapping, and exact peripheral channel counts per variant.
Technical Context
The R9A07G084M04GBA#AC0 implements a single-core Arm Cortex-R52 (r1p3) with Harvard architecture, 8-stage pipeline, and dual-stage MPU (EL1/EL2) for safety partitioning. It integrates two DMAC units (8 channels each), event link controller (ELC) enabling CPU-standby module chaining, and isolated safety peripherals including 4 GPT, 1 SCI, 1 IIC, and 1 SPI channel.
Its real-time subsystem includes MTU3 (9 channels), GPT (18 channels), CMT (6 channels), and CMTW (2 channels), all supporting input capture, PWM waveform generation, and dead-time compensation. The device supports XiP via xSPI (1 channel, 3.3 V only), 12-bit ADC (unit 1 only, 8 channels), and trigonometric function unit (TFU) for simultaneous sine/cosine and arctangent/hypotk computation.

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 |
|---|---|---|---|
| R9A07G084M08GBA | Same 121-pin FBGA package but includes optional security features (secure boot, JTAG auth, crypto accelerators enabled). | Required for deployments needing certified secure firmware updates or TLS offload; not needed for basic motion control. | Select R9A07G084M08GBA when cryptographic acceleration or secure boot is mandatory; R9A07G084M04GBA#AC0 suffices for cost-sensitive non-security use cases. |
| R9A07G084M04GBG | 225-pin FBGA package (13 × 13 mm), adds USB 2.0 HS host/function, Ethernet MAC, PHOSTIF, and full 12-bit ADC (2 units). | Suitable for larger HMI-integrated controllers or gateways requiring USB peripheral connectivity and expanded analog I/O. | Choose R9A07G084M04GBG when USB host capability, additional ADC channels, or parallel host interface are required - not pin-compatible with R9A07G084M04GBA#AC0. |
Compared with R9A07G084M08GBA, the R9A07G084M04GBA#AC0 omits security IP blocks to reduce BOM cost while retaining identical real-time performance and peripheral count; versus R9A07G084M04GBG, it trades package size and USB/ADC capacity for compactness and thermal efficiency in space-constrained drives.

FAQ
What is the maximum operating junction temperature for R9A07G084M04GBA#AC0?
The R9A07G084M04GBA#AC0 is rated for Tj = −40 to +125°C, validated across its full voltage and frequency range. This specification enables deployment in sealed industrial enclosures without active cooling, such as motor drive cabinets or outdoor control panels. Thermal design must maintain junction temperature within this limit using appropriate PCB copper area and heatsinking per Renesas AN-932 guidelines.
Does R9A07G084M04GBA#AC0 support USB 2.0 host functionality?
No, R9A07G084M04GBA#AC0 does not include USB 2.0 host functionality. That feature is present only in the 225-pin variants (e.g., R9A07G084M04GBG). The R9A07G084M04GBA#AC0 retains USB 2.0 device-mode capability for firmware updates or CDC-class communication but lacks the host PHY and associated DMA channels required for peripheral enumeration.
How many CAN FD channels does R9A07G084M04GBA#AC0 support, and what are their compliance details?
R9A07G084M04GBA#AC0 supports two CAN FD channels compliant with ISO 11898-1:2015. Each channel operates at up to 1 Mbps in classical CAN mode and up to 8 Mbps data bit rate in CAN FD mode, with configurable 11-bit standard or 18-bit extended ID formats. Message buffering includes 64 dedicated TX buffers and 128 shared TX/RX buffers with FIFO support.
Is the 12-bit ADC available on R9A07G084M04GBA#AC0, and how many channels does it provide?
Yes, R9A07G084M04GBA#AC0 includes one 12-bit ADC unit (ADC121) with eight input channels. The second ADC unit (ADC120, 4 channels) is disabled in the 121-pin package variant per Table 1.16 of the datasheet. Conversion time is 0.84 µs per channel, and triggering supports software, MTU3/GPT timers, or external signals via the Event Link Controller.
What safety certifications does R9A07G084M04GBA#AC0 target, and which hardware features enable them?
R9A07G084M04GBA#AC0 targets IEC 61508 SIL2 and ISO 13849 PL e certification through hardware features including dual-stage MPU (EL1/EL2), CRC-32C calculator, clock monitor circuit (CLMA), register write protection, and isolated safety peripherals (4 GPT, 1 SCI, 1 IIC, 1 SPI). These elements provide fault detection, memory protection, and hardware-enforced partitioning required for safety subsystem validation.
