Product details
Overview
R9A07G043F01GBG#AC0 from Renesas Electronics is a high-performance 64-bit RISC-V microprocessor in the RZ/Five group, featuring a single-core AndesCore™ AX45MP CPU running at up to 1 GHz, integrated L1/L2 cache, dual Gigabit Ethernet MACs, and hardware-accelerated security including TrustZone®-enabled memory protection. It targets industrial HMI, edge AI inference gateways, and real-time Linux-based control systems requiring deterministic I/O and secure boot.
For engineers reviewing the R9A07G043F01GBG#AC0 datasheet, R9A07G043F01GBG#AC0 pinout, R9A07G043F01GBG#AC0 application, or R9A07G043F01GBG#AC0 equivalent, key selection criteria include its 1 GHz AX45MP core frequency, dual GbE PHY interface support, 3.3-V/1.8-V eMMC boot capability, and 17 mm × 17 mm BGA-521 package with 0.8-mm pitch.
Technical Context
The R9A07G043F01GBG#AC0 implements a full-featured RISC-V application processor subsystem with AX45MP core, L1 instruction/data caches (32 KB each), 512 KB unified L2 cache, and memory management unit (MMU) supporting virtual memory. Its system bus architecture includes AXI4 interconnect, security-aware bus masters/slaves, and configurable ECC for on-chip RAM blocks.
Boot flexibility is provided via six modes including eSD, 1.8-V/3.3-V eMMC, quad SPI flash, and SCIF downloading - all managed by dedicated boot ROM firmware. The SYSC block provides centralized control of reset, clock gating, WDT, peripheral configuration registers (e.g., SYS_GETH0_CFG, SYS_I2C0_CFG), and TrustZone®-based memory access enforcement.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RISC-V application processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R9A07G044F01GBG#AC0 | Same AX45MP core, identical package, but adds PCIe Gen2 x1 controller and USB 3.0 PHY - no eSD boot support. | Better suited for vision-based robotics requiring camera interface bandwidth; less optimal for pure industrial networking where eSD is preferred. | Select R9A07G044F01GBG#AC0 only if PCIe/USB 3.0 connectivity outweighs eSD boot requirement. |
| SiFive U74-MC | Quad-core U74 (RV64GC), no integrated Ethernet MACs, 28 nm process - lower power but higher area and no hardware TrustZone®. | Targeted at ultra-low-power always-on edge nodes; lacks integrated networking and security IP needed for certified industrial control. | Choose SiFive U74-MC for battery-powered sensor hubs; avoid for safety-certified gateway applications requiring dual GbE and hardware-enforced isolation. |
Compared with R9A07G043F01GBG#AC0, the R9A07G044F01GBG#AC0 adds PCIe/USB 3.0 at the cost of eSD boot, while SiFive U74-MC offers multi-core scalability but lacks integrated networking and certified security features - making R9A07G043F01GBG#AC0 optimal for secure, networked industrial gateways.

FAQ
What is the maximum operating frequency of the R9A07G043F01GBG#AC0 CPU core?
The R9A07G043F01GBG#AC0 integrates a single AndesCore™ AX45MP 64-bit RISC-V CPU core rated for operation up to 1 GHz under specified thermal and voltage conditions. This frequency is achievable with proper PCB layout, thermal management (≤70°C junction temperature), and stable 1.0 V ±3% core supply. The R9A07G043F01GBG#AC0 does not support dynamic frequency scaling beyond this fixed maximum.
Does the R9A07G043F01GBG#AC0 support secure boot from external flash memory?
Yes, the R9A07G043F01GBG#AC0 supports secure boot from 1.8-V or 3.3-V serial flash memory (Boot Modes 3 and 4). Its on-chip ROM validates SHA-256 hashes and RSA-2048 signatures of the first-stage bootloader before execution. This validation applies only to images loaded directly from flash - not to secondary payloads loaded later by software. The R9A07G043F01GBG#AC0 requires external flash with write-protection enabled to prevent unauthorized modification of signed boot code.
What Ethernet physical layer interfaces are supported by the R9A07G043F01GBG#AC0?
The R9A07G043F01GBG#AC0 integrates two independent Gigabit Ethernet MACs with RGMII and SGMII interface support. It does not include integrated PHYs; external 10/100/1000BASE-T PHYs must be connected via RGMII (for copper) or SGMII (for fiber or backplane). The R9A07G043F01GBG#AC0 provides MDIO/MDC signals for PHY register access and supports IEEE 1588 hardware timestamping on both MACs for precise time synchronization.
Is the R9A07G043F01GBG#AC0 pin-compatible with other RZ/Five family members?
No, the R9A07G043F01GBG#AC0 is not pin-compatible with other RZ/Five variants such as R9A07G044F01GBG#AC0. Although both use the same 521-ball FBGA package with identical mechanical dimensions and ball pitch, their pin functions differ significantly - particularly for PCIe, USB, and eSD interfaces. Board-level redesign is required when migrating between these variants due to incompatible signal assignments and power domain configurations.
What development tools are officially supported for the R9A07G043F01GBG#AC0?
Renesas provides official support for the R9A07G043F01GBG#AC0 through the RZ/Five Starter Kit (RTK0EG0032S01000BE), which includes a reference board, pre-certified power management ICs, and validated Linux BSP with Yocto Project integration. Debugging uses JTAG via CMSIS-DAP compliant debug probe. Renesas e2 studio IDE and GNU RISC-V toolchain (riscv64-elf-gcc) are fully supported; no third-party IDEs are officially qualified for production firmware development on the R9A07G043F01GBG#AC0.
