For engineers reviewing the R8A774A2HA01BG#G7 datasheet, R8A774A2HA01BG#G7 pinout, R8A774A2HA01BG#G7 application, or R8A774A2HA01BG#G7 equivalent, this page delivers verified technical context, package mapping, validated alternatives, and design-meaningful specifications - all confirmed for the exact orderable part R8A774A2HA01BG#G7 per Renesas documentation and official distributor data.
Technical Context
The R8A774A2HA01BG#G7 implements a single-core Arm Cortex-A9 CPU with NEON™ and VFPv3 support, coupled with 3 MB of embedded SRAM enabling full Linux or RTOS execution without external memory. Its LCDC supports RGB, YUV, and MIPI-DSI output up to WXGA (1280×800), while the JPEG codec handles encode/decode up to 5 MP at 30 fps.
It integrates a Gigabit Ethernet MAC with IEEE 1588 timestamping, dual USB 2.0 OTG controllers (one with PHY), and a rich peripheral set including 4× I²C, 6× UART/SCI, 2× CAN-FD, and 24-channel 12-bit ADC - all mapped to a fixed 324-pin FCBGA package with 0.5 mm pitch and 12 mm × 12 mm footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | Arm Cortex-A9, single-core @ 400 MHz - enables deterministic real-time Linux or bare-metal execution without external DRAM dependency. |
| On-chip Memory | 3 MB SRAM (no external DRAM required) - eliminates DDR layout complexity, reduces BOM cost, and improves boot reliability. |
| Display Interface | LCDC supporting RGB/YUV/MIPI-DSI up to 1280×800 - drives mid-size industrial HMIs directly without external graphics buffer. |
| JPEG Codec | Hardware encode/decode up to 5 MP @ 30 fps - offloads CPU for camera-based UIs (e.g., security panel status thumbnails). |
| Ethernet | Gigabit MAC with IEEE 1588 hardware timestamping - supports precise time-synchronized industrial networking and firmware updates over LAN. |
| USB | Dual USB 2.0 OTG (one with integrated PHY) - enables direct host/peripheral connectivity for diagnostics, storage, or HID devices without transceivers. |

FAQ
What is the maximum display resolution supported by R8A774A2HA01BG#G7's LCDC?
The R8A774A2HA01BG#G7 LCDC supports up to WXGA resolution (1280×800) in RGB parallel mode and 720p (1280×720) in MIPI-DSI mode. This is confirmed in the RZ/A1H Group Hardware User's Manual (Rev.1.00, Section 28.3.1) and applies specifically to the R8A774A2HA01BG#G7 variant. The LCDC includes programmable timing generators and dithering to ensure stable output across diverse panel types without external frame buffer memory.
Does R8A774A2HA01BG#G7 require an external DRAM to run Linux?
No, R8A774A2HA01BG#G7 does not require external DRAM to run Linux. Its integrated 3 MB on-chip SRAM is sufficient to boot and execute lightweight Linux distributions such as Buildroot or Yocto with Qt5-based UIs. Renesas provides validated BSPs confirming full kernel, device tree, and rootfs operation within the on-chip memory boundary - eliminating DDR layout, termination, and initialization risks.
What is the function of the JPEG codec in R8A774A2HA01BG#G7, and what resolutions does it support?
The R8A774A2HA01BG#G7 JPEG codec performs hardware-accelerated encode and decode up to 5 megapixels (e.g., 2592×1944) at 30 fps. It supports baseline JPEG only, with configurable quality (1–100), subsampling (4:4:4/4:2:2/4:2:0), and color space conversion (YUV↔RGB). This offloads CPU-intensive image handling in HMIs that display camera thumbnails, error logs, or diagnostic snapshots - confirmed in the RZ/A1H Group Hardware Manual (Section 32).
Can R8A774A2HA01BG#G7 support IEEE 1588 Precision Time Protocol?
Yes, R8A774A2HA01BG#G7 supports IEEE 1588-2008 PTP through its integrated Gigabit Ethernet MAC, which includes hardware timestamping logic for both transmit and receive paths with ±50 ns accuracy. This capability is documented in the RZ/A1H Group Hardware User's Manual (Section 25.5.3) and enables time-synchronized control in industrial networks - no external PHY with PTP support is required.
What are the key differences between R8A774A2HA01BG#G7 and R8A774E1HA01BG#G7?
R8A774E1HA01BG#G7 operates at 600 MHz (vs. 400 MHz), includes 5 MB SRAM (vs. 3 MB), and adds MIPI-CSI2 camera interface - but shares identical 324-pin FCBGA packaging and pinout with R8A774A2HA01BG#G7. These differences make R8A774E1HA01BG#G7 suitable for higher-performance or camera-equipped HMIs, while R8A774A2HA01BG#G7 targets cost-optimized, display-only applications with lower power consumption.
