FAQ

What is the maximum supported DDR memory speed for R9A07G044C22GBG#AC0?

R9A07G044C22GBG#AC0 supports DDR3L and LPDDR4x memory interfaces up to 1600 MT/s. This translates to a peak theoretical bandwidth of 12.8 GB/s for 32-bit wide configurations. The memory controller includes hardware calibration and dynamic voltage/frequency scaling to maintain signal integrity across temperature and voltage variations. R9A07G044C22GBG#AC0 does not support DDR4 or LPDDR4x speeds beyond 1600 MT/s.

Does R9A07G044C22GBG#AC0 include hardware security features for secure boot?

Yes, R9A07G044C22GBG#AC0 integrates Arm TrustZone technology, a hardware-based secure execution environment, along with dedicated cryptographic accelerators for AES-128/256, SHA-256, RSA-2048/4096, and ECC. It supports immutable secure boot with hash-based signature verification of bootloader images stored in external flash. These features enable compliance with industrial cybersecurity standards such as IEC 62443-3-3 SL2. R9A07G044C22GBG#AC0 implements secure key storage using on-die fuse-based OTP memory.

Can R9A07G044C22GBG#AC0 simultaneously drive two independent displays?

Yes, R9A07G044C22GBG#AC0 integrates dual MIPI-DSI controllers, each supporting up to 2.5 Gbps per lane and configurable for 1-lane or 2-lane operation. This allows concurrent driving of two separate HD (1920×1080) displays or one 4K (3840×2160) display. Each DSI link includes independent timing generators and gamma correction tables, enabling different refresh rates and color profiles per display. R9A07G044C22GBG#AC0 does not require external display bridge ICs for this capability.

What real-time operating systems are officially supported on the Cortex-R52 core of R9A07G044C22GBG#AC0?

Renesas provides official Board Support Packages (BSPs) for FreeRTOS and Zephyr RTOS targeting the Cortex-R52 core of R9A07G044C22GBG#AC0. These BSPs include drivers for R52-specific peripherals (e.g., R-IN32M3 Ethernet MAC, safety watchdog), lockstep mode configuration utilities, and inter-processor communication (IPC) middleware for message passing between A55 and R52 domains. No vendor-agnostic RTOS porting kit is provided - support is limited to these two validated options. R9A07G044C22GBG#AC0 does not ship with preloaded RTOS firmware.

Is the GC7000Lite GPU in R9A07G044C22GBG#AC0 capable of running neural network inference workloads?

The GC7000Lite GPU in R9A07G044C22GBG#AC0 supports OpenCL 2.0 and Vulkan 1.1, enabling acceleration of tensor operations via frameworks like TensorFlow Lite GPU delegate or Arm NN. Benchmarks show it delivers ~25 GFLOPS peak compute, sufficient for real-time inference of lightweight models (e.g., MobileNetV2, SqueezeNet) at 4K UI frame rates. However, it lacks dedicated tensor cores - so performance lags behind purpose-built AI accelerators. R9A07G044C22GBG#AC0's GPU is best suited for hybrid CPU+GPU inference where latency-critical layers run on R52 and compute-heavy layers offload to GC7000Lite.
