FAQ

What is the CPU architecture and clock speed of the R9A07G044L28GBG#AC0?

The R9A07G044L28GBG#AC0 integrates two Arm® Cortex®-A55 application processor cores operating at 1.2 GHz and one Arm® Cortex®-M33 real-time microcontroller core at 200 MHz. Each A55 core has 32KB instruction cache (parity-protected) and 32KB data cache (ECC-protected), with a shared 256KB L3 cache (ECC). This heterogeneous architecture enables concurrent Linux application execution and deterministic real-time control within a single die.

Does the R9A07G044L28GBG#AC0 support DDR4 memory with ECC?

Yes, the R9A07G044L28GBG#AC0 supports 16-bit DDR4 and DDR3L memory interfaces at data rates up to 1.6 GT/s (DDR4) or 1.3 GT/s (DDR3L), with inline ECC functionality enabled. It also includes 128KB of on-chip SRAM with built-in ECC protection. These features provide end-to-end data integrity for industrial applications where memory corruption must be prevented in harsh electromagnetic environments.

What video and graphics capabilities does the R9A07G044L28GBG#AC0 offer?

The R9A07G044L28GBG#AC0 integrates an Arm® Mali™-G31 GPU supporting OpenGL ES 3.2 for UI rendering and a hardware H.264 encoder/decoder capable of 1920×1080@30fps. It does not support H.265. The GPU and video codec operate independently of the CPU cores, enabling simultaneous UI composition, video capture, and analytics preprocessing - critical for smart camera and HMI use cases where latency and CPU offload matter.

Which camera and display interfaces are supported by the R9A07G044L28GBG#AC0?

The R9A07G044L28GBG#AC0 supports MIPI CSI-2 (4-lane) for camera input and MIPI DSI (4-lane) for display output, both compliant with v1.2/v1.3 specifications. It also offers parallel interface alternatives for legacy sensors and displays. Signal integrity requirements include controlled 100Ω differential impedance for MIPI lanes and strict length matching across all data and clock pairs to maintain timing margins at 1.5 Gbps per lane.

What security features are integrated into the R9A07G044L28GBG#AC0?

The R9A07G044L28GBG#AC0 includes Arm® TrustZone® for hardware-enforced secure world isolation, Secure Boot with signature verification, Device Unique ID, True Random Number Generator (TRNG), 4Kbit One-Time Programmable (OTP) memory, JTAG disable, and a dedicated crypto engine supporting AES-128/256, SHA-256, and RSA-2048. These features collectively enable CIP Linux-certified secure firmware updates and protected key storage for industrial and IoT deployments.
