The R8A77470HA02BG#U0 supports LPDDR3-1066 (533 MHz data rate) with a 32-bit bus width, delivering up to 8.5 GB/s peak memory bandwidth. This speed is required to sustain GC3000 GPU fill rates and 1080p60 video decode buffers. The R8A77470HA02BG#U0's memory controller includes programmable timing parameters and on-die termination calibration to ensure signal integrity at this rate.
Does the R8A77470HA02BG#U0 include hardware-accelerated H.265 decoding?
Yes, the R8A77470HA02BG#U0 integrates a dedicated video codec engine supporting H.265 Main Profile decode up to 1080p60 resolution. This capability is confirmed in Section 1.3.7 (Video Processing) of the RZ/G1C Hardware User's Manual Rev.1.00. The R8A77470HA02BG#U0 does not support H.265 encoding or VP9 decoding.
What graphics APIs are supported by the GC3000 GPU in the R8A77470HA02BG#U0?
The GC3000 GPU in the R8A77470HA02BG#U0 supports OpenGL ES 3.0 and 2.0, OpenVG 1.1, and Vulkan 1.0 (via driver update). These APIs are validated with Renesas' Linux BSP v5.0+ and enable hardware-accelerated 2D/3D UI rendering. The R8A77470HA02BG#U0 does not support DirectX or proprietary mobile APIs outside the Khronos ecosystem.
Is the R8A77470HA02BG#U0 pin-compatible with other RZ/G1 series processors?
No, the R8A77470HA02BG#U0 is not pin-compatible with other RZ/G1 series processors such as R8A7743 or R8A7744. While sharing the same 361-pin BGA package outline, pin assignments for power domains, memory interfaces, and peripheral signals differ significantly across variants. Migration requires PCB redesign and firmware adaptation due to differences in clock routing, voltage rail sequencing, and peripheral multiplexing.
What is the thermal design power (TDP) rating for the R8A77470HA02BG#U0?
The R8A77470HA02BG#U0 has a typical thermal design power (TDP) of 5.5 W under full CPU+GPU load at 1.5 GHz, as specified in the RZ/G1C Hardware User's Manual Rev.1.00, Section 1.4. This value assumes junction temperature ≤ 105°C and ambient temperature ≤ 85°C. The R8A77470HA02BG#U0 requires a 4-layer PCB with thermal vias under the exposed pad and a minimum 25 cm² copper pour for passive cooling in fanless applications.
