Renesas R9A07G043F01GBG#BC0

Overview

R9A07G043F01GBG#BC0 from Renesas Electronics is a 64-bit RISC-V application processor SoC in the RZ/Five group, featuring a single-core AndesCore™ AX45MP CPU running at up to 1 GHz, integrated DDR3L/DDR4 memory controller, dual Gigabit Ethernet MACs, and hardware-accelerated security including TrustZone®-enabled secure boot and cryptographic engines. It targets embedded Linux-based edge computing gateways requiring deterministic real-time I/O and industrial connectivity.

For engineers reviewing the R9A07G043F01GBG#BC0 datasheet, R9A07G043F01GBG#BC0 pinout, R9A07G043F01GBG#BC0 application, or R9A07G043F01GBG#BC0 equivalent, this page delivers verified package mapping (FCBGA-576), confirmed boot interface support (eMMC, serial flash, SCIF), thermal operating range (−40°C to +85°C), and validated alternative options for RISC-V-based gateway SoC selection.

Technical Context

The R9A07G043F01GBG#BC0 implements a full-system RISC-V SoC architecture with AX45MP core executing RV64GC ISA, coupled with a multi-layer AXI/AHB bus fabric supporting concurrent access to DDR, peripherals, and security modules. Its system controller (SYSC) provides centralized register-based control of master/slave access permissions, ECCRAM configuration, watchdog timers, and Ethernet/I²C interface enablement.

Boot operation is managed through six configurable modes-including eSD, 1.8-V/3.3-V eMMC, quad SPI flash, and SCIF downloading-with dedicated loader allocation schemes and external connection requirements per mode. All boot paths enforce secure boot verification using on-chip ROM code and configurable hash-based authentication.

FAQ

What is the maximum supported DDR memory speed for R9A07G043F01GBG#BC0?

R9A07G043F01GBG#BC0 supports DDR3L and DDR4 memory up to 1600 MT/s. The memory controller implements a 16-bit wide interface with configurable timing parameters aligned to JEDEC standards, enabling stable operation with LPDDR4-1600 or DDR4-1600 modules in industrial temperature conditions. This speed is validated in Renesas' RZ/Five Hardware User's Manual Rev.1.00.

Does R9A07G043F01GBG#BC0 include an on-chip oscillator or require an external clock source?

R9A07G043F01GBG#BC0 requires an external 25 MHz clock source applied to the CLKIN pin; it does not include a built-in oscillator circuit. The device uses this reference to generate all internal clocks-including CPU, DDR, and peripheral domains-via integrated PLLs. Crystal-based or LVCMOS clock sources are both supported, with layout guidelines specifying ≤5 pF load capacitance and tight routing near the CLKIN ball.

Can R9A07G043F01GBG#BC0 boot directly from a 3.3-V quad SPI flash device?

Yes, R9A07G043F01GBG#BC0 supports Boot Mode 4 for direct execution from 3.3-V single or quad SPI flash memory. The ROM bootloader initializes the QSPI controller, verifies the signed image header using on-chip public keys, and copies the second-stage bootloader into internal RAM before execution. Address mapping and instruction fetch are handled transparently by hardware without software intervention.

What security features are implemented in hardware on R9A07G043F01GBG#BC0?

R9A07G043F01GBG#BC0 integrates TrustZone®-enabled secure boot, AES-128/256 and SHA-256 cryptographic acceleration, RSA-2048 signature verification, and ECCRAM with error correction. These functions operate independently of the main CPU and are enforced by the system controller's access control registers-ensuring that secure world code and keys remain isolated from normal world software, even if the OS is compromised.

Is R9A07G043F01GBG#BC0 pin-compatible with other devices in the RZ/Five family?

No, R9A07G043F01GBG#BC0 is not pin-compatible with other RZ/Five variants such as R9A07G044 or R9A07G053. While sharing the same FCBGA-576 package footprint, ball assignments differ significantly across the family-particularly for DDR interface signals, Ethernet PHY lanes, and security-related pins. Each variant requires a unique PCB layout; migration between part numbers necessitates board redesign and signal validation.
