1. R7F701412EABG Core Hardware Architecture and Performance Parameters  

Processor and Computing Power

Core: Features a 32-bit RH850G3M single-core processor with a clock speed of 240MHz, manufactured using a 40nm process technology, balancing high performance and low power consumption.

Memory Resources:

Program Flash: 3.75MB (supports storage of complex graphics firmware)

RAM: 512KB (for real-time data processing)

EEPROM: 64KB (for configuration parameter storage).

Peripheral Interfaces:  

Communication Interfaces: CANbus, Ethernet, USB, I2C, SPI, UART, etc., supporting multi-system collaboration in vehicle applications.  

Control Peripherals: 20-channel 12-bit ADC (analogue signal acquisition), PWM output, DMA controller, watchdog timer (WDT).  

Package and Reliability

Package: 484-pin BGA (27×27mm), surface-mount design, suitable for high-temperature and high-vibration environments.  

Operating conditions:  

Voltage range: 2.7V–5.5V (compatible with vehicle power supply fluctuations)  

Temperature range: -40°C to 150°C (junction temperature), meeting automotive-grade extreme environment requirements.

II. R7F701412EABG Graphics Processing Capability: Low-level 2D graphics engine  

Basic graphics functions  

Display control: Integrated dedicated 2D graphics engine supporting the following core functions:  

Layer management: Supports multi-layer overlay (2–3 layers), enabling Alpha blending (transparency blending) and dynamic compositing.

Drawing primitives: Hardware-accelerated rendering of basic geometric shapes such as lines, polygons, and circles.  

Framebuffer control: Built-in framebuffer mechanism optimises display refresh rate (50–60 Hz).  

Resolution adaptation: Supports up to ultra-wide VGA (1240×480 pixels), accommodating the wide-screen requirements of digital instrument clusters and HUDs.  

Resource-optimised design

Low memory dependency: Reduces external memory access by directly operating the framebuffer, lowering system latency.  

CPU load offloading: Graphics tasks are processed by a dedicated engine, freeing up main CPU resources (such as the RH850G3M core) for safety-critical tasks (such as ADAS data processing).
