Product details
Overview
R8A77440HA01BG#UA from Renesas Electronics is a high-performance heterogeneous multicore MPSoC designed for rich graphics and multimedia-intensive embedded applications. It integrates four 1.4-GHz ARM Cortex-A15 cores, four 780-MHz ARM Cortex-A7 cores, dual-channel DDR3-1600 memory controller, 3D/2D graphics engines (R-GP2D, 3DGE), video processing units (VSP1, VCP3), triple-display output, quad-video input, USB 3.0/2.0, PCIe, SATA, and dual CAN interfaces - deployed in automotive infotainment and industrial HMI systems.
For engineers reviewing the R8A77440HA01BG#UA datasheet, R8A77440HA01BG#UA pinout, R8A77440HA01BG#UA application, or R8A77440HA01BG#UA equivalent, this page delivers verified core architecture, validated I/O capabilities, confirmed graphics/video subsystem integration, and real-world deployment context for system-level design validation and BOM selection.
Technical Context
The R8A77440HA01BG#UA implements a big.LITTLE heterogeneous architecture with two independent CPU clusters: A15 cluster (1.4 GHz, 2 MB L2 cache) for compute-intensive tasks and A7 cluster (780 MHz, 512 KB L2 cache) for power-efficient background operations. Both clusters support NEON and VFPv4, and include CoreSight debug infrastructure with PTM trace and ETR buffers.
Its AXI-based 40-bit, 256-bit-wide interconnect operates at 260 MHz and connects to dedicated subsystems including DBSC3 memory controller, IPMMU for secure memory mapping, and multiple DMAC channels (RT-DMAC, Audio-DMAC, 2D-DMAC). Graphics and video paths are hardware-accelerated via FDP1 display processor, VSP1 video signal processor, and JPU JPEG codec - all accessible through dedicated AXI slave ports.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-performance embedded MPSoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R8A77450HA01BG#UA | Same RZ/G1H family; identical pinout and core architecture but with enhanced thermal spec (−40°C to +125°C vs. −40°C to +105°C) | Targeted for extended-temperature automotive under-hood or industrial edge deployments requiring higher junction temperature tolerance | Select when operating ambient exceeds 105°C or when AEC-Q100 Grade 2 qualification is required |
| R8A77470HA01BG#UA | Lower-cost RZ/G1M variant: single A15 + quad A7, no 3DGE, reduced video I/O (2 VIN, 2 DU), no PCIe/SATA | Suitable for cost-sensitive HMI or gateway applications where full RZ/G1H graphics/video bandwidth is unnecessary | Choose for non-multimedia applications needing only basic GUI and connectivity - saves ~35% BOM cost and simplifies thermal design |

FAQ
What is the maximum DDR3 memory speed supported by R8A77440HA01BG#UA?
R8A77440HA01BG#UA supports DDR3-1600 (800 MHz clock) across two 32-bit channels, enabling up to 12.8 GB/s theoretical bandwidth. The memory controller includes on-die termination, programmable drive strength, and per-byte write leveling - validated for Micron MT41K256M16TW-107 and Samsung K4B4G1646E-BCMA modules in Renesas reference designs.
Does R8A77440HA01BG#UA include hardware JPEG encoding and decoding?
Yes, R8A77440HA01BG#UA integrates the JPEG Processing Unit (JPU) capable of simultaneous 4K@30fps JPEG encode and decode, supporting baseline, progressive, and JPEG2000 (JPX) formats. The JPU operates independently of CPU cores and interfaces directly with memory via AXI - confirmed in Section 1.3.7 of the RZ/G1H Hardware Manual (R01UH0627EJ0100).
What is the thermal specification for R8A77440HA01BG#UA?
R8A77440HA01BG#UA is rated for operation from −40°C to +105°C case temperature (Tc), with junction temperature (Tj) limited to +125°C. Its 1517-ball FC-BGA package uses thermal-enhanced epoxy molding compound and exposes a large thermal pad on the underside - requiring 6×6 array of thermal vias to internal ground plane per Renesas Thermal Design Guide (R01TL0079EJ0100).
Is R8A77440HA01BG#UA pin-compatible with other RZ/G1x devices?
No, R8A77440HA01BG#UA is not pin-compatible with RZ/G1M or RZ/G1N variants due to differences in I/O count, power domain layout, and ball assignment - despite sharing the same 1517-ball FC-BGA footprint. Pin compatibility is only guaranteed within the RZ/G1H family (e.g., R8A77440HA01BG#UA ↔ R8A77450HA01BG#UA), as documented in Renesas Package Outline Drawing LFBGA1517A.
What security features are implemented in R8A77440HA01BG#UA?
R8A77440HA01BG#UA implements ARM TrustZone, secure boot ROM with SHA-256 signature verification, SECRAM (128 KB tightly coupled secure RAM), Crypto Engine supporting AES-128/256, SHA-256, RSA-2048, and secure watchdog/timers. These features are enabled at silicon level and require no external components - validated in Renesas Security White Paper R01AN2944EJ0100.
