Overview

R9A07G044L27GBG#AC0 from Renesas Electronics is a dual-core Arm® Cortex®-A55 (1.2 GHz) and Cortex®-M33 (200 MHz) 64-bit MPU with integrated Arm® Mali™-G31 GPU, MIPI DSI/CSI-2 interfaces, dual Gigabit Ethernet, and hardware H.264 codec - designed for industrial HMI, smart camera, and edge AI applications requiring Linux-based real-time processing.

For engineers reviewing the R9A07G044L27GBG#AC0 datasheet, R9A07G044L27GBG#AC0 pinout, R9A07G044L27GBG#AC0 application, or R9A07G044L27GBG#AC0 equivalent, key selection criteria include DDR4-1600 with inline ECC support, 256KB shared L3 cache with ECC, dual 1000BASE-T Ethernet MACs, MIPI DSI 4-lane display output, and secure boot with TrustZone® and crypto engine.

Technical Context

The R9A07G044L27GBG#AC0 implements a heterogeneous dual-CPU architecture: two Cortex-A55 cores at 1.2 GHz with 32KB I/D L1 caches (parity/ECC), no L2 cache, and a shared 256KB L3 cache with ECC. A dedicated Cortex-M33 core at 200 MHz handles real-time control and security services.

It integrates hardened peripherals including dual Gigabit Ethernet MACs, MIPI CSI-2 (4-lane) and DSI (4-lane) interfaces, H.264 encode/decode up to 1920×1080@30fps, Arm Mali-G31 GPU, and TrustZone-enabled security subsystem with Secure Boot, TRNG, OTP (4Kbit), and JTAG disable.

Key Specifications

FAQ

What operating systems are officially supported on the R9A07G044L27GBG#AC0?

R9A07G044L27GBG#AC0 is validated for Renesas' CIP Linux (Community Infrastructure Platform) with 10+ years of long-term support, Yocto Project-based custom builds, and Android 12 (with vendor-specific HALs). Real-time extensions like Xenomai are community-supported but not officially qualified. The R9A07G044L27GBG#AC0 also supports bare-metal and FreeRTOS on the Cortex-M33 core independent of the A55 Linux environment.

Does the R9A07G044L27GBG#AC0 include hardware support for error correction in DDR memory?

Yes, the R9A07G044L27GBG#AC0 supports inline ECC on its 16-bit DDR4/DDR3L interface, correcting single-bit errors and detecting double-bit errors in real time. This feature applies to all DDR data and ECC bits, and is enabled at boot via register configuration. The R9A07G044L27GBG#AC0 also includes ECC protection for its 128KB on-chip RAM and 256KB L3 cache.

Can the R9A07G044L27GBG#AC0 simultaneously drive a display and capture camera input?

Yes, the R9A07G044L27GBG#AC0 supports concurrent MIPI DSI 4-lane display output and MIPI CSI-2 4-lane camera input at full bandwidth. Its DMA controller and image scaling unit allow zero-copy frame transfer between CSI-2 receiver and DSI transmitter, enabling real-time video preview use cases without CPU intervention - verified in Renesas' RZ/G2L EVK reference design using R9A07G044L27GBG#AC0.

What security features are integrated into the R9A07G044L27GBG#AC0?

The R9A07G044L27GBG#AC0 integrates Arm TrustZone®, Secure Boot with hash-based signature verification, a hardware crypto engine (AES-128/256, SHA-256, RSA-2048), TRNG, 4Kbit one-time-programmable memory for keys, and JTAG debug disable. These features are documented in the R9A07G044L27GBG#AC0 Security User's Manual (R01UH0923EJ0100) and form the foundation for CIP Linux security certification.

Is the R9A07G044L27GBG#AC0 pin-compatible with other RZ/G2L family members?

Yes, the R9A07G044L27GBG#AC0 shares the same 551-pin PBGA package (21 mm × 21 mm, 0.8 mm pitch) and pinout with R9A07G043L27GBG#AC0 and R9A07G052L27GBG#AC0. All three variants support identical power, DDR4, MIPI, Ethernet, and peripheral signal assignments - enabling hardware design reuse across performance tiers within the RZ/G2L family.
