Product details
Overview
R8A77420HA02BG#UA from Renesas Electronics is a high-performance heterogeneous multicore MPUs targeting rich graphics and multimedia-intensive embedded systems. 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 (3DGE/R-GP2D), video processing units (VSP1/VCP3), and triple-display output capability - enabling simultaneous 4K-capable UI rendering, video playback, and real-time camera input in automotive infotainment head units.
For engineers reviewing the R8A77420HA02BG#UA datasheet, R8A77420HA02BG#UA pinout, R8A77420HA02BG#UA application, or R8A77420HA02BG#UA equivalent, key selection considerations include its dual-cluster big.LITTLE architecture, integrated PCIe Gen2 x1, SATA II, USB 3.0 host, CAN v2.0B (2-channel), and AVB Ethernet MAC - all within a single 19×19 mm 515-pin FC-BGA package rated for industrial temperature range (–40°C to +85°C).
Technical Context
The R8A77420HA02BG#UA implements a hierarchical AXI-based interconnect with 40-bit address space and 256-bit data width operating at up to 260 MHz, supporting cache-coherent communication between A15 and A7 clusters via shared L2 caches and system-level coherency logic. Its CPG module generates independent clock domains for CPU cores, memory bus (800 MHz DDR3), media subsystems (260 MHz), and peripherals (130 MHz HPϕ), with dynamic voltage and frequency scaling (DVFS) support across both CPU clusters.
Hardware security features include TrustZone-enabled secure boot, SECRAM for encrypted code execution, Crypto Engine (AES/SHA/RSA), and Secure WDT - all managed through SYSC power-domain control that enables independent shutdown of Cortex-A15, Cortex-A7, and 3DGE modules without affecting system stability or peripheral operation.
