Electronics News
The MB91590 series provides a System-on-a-Chip (SoC) solution for color display, video input and meter control systems for automotive dashboard and human machine interface (HMI) applications.
It integrates a high performance FR81S CPU core offering the highest CPU performance level in the industry, a graphics display controller (GDC) with strong sprite functionality, rendering engine, and external video capture capabilities. The MB91590 series also features support for dual LCD displays.
The MB91590 series offers a single-chip solution for applications that require robust color display and video-input capabilities. It is particularly well-suited for use in automotive instrument clusters and center consoles using color displays to generate flexible and intuitive driver interfaces.
Applications
- Automotive instrument clusters
- Center consoles using color display
- Vehicle camera system
- Industrial controllers with color display
Key Features
The MB91590 series utilizes a FR81S CPU core operating at a maximum internal operating frequency of 128MHz. The MCU also includes a built-in single-precision floating point unit for high-speed operations, and a memory protection unit capable of providing selective access to protected memory areas.
Peripheral functions optimized for dashboard systems reduce the need for extra components. Multiple built-in regulators and a flexible standby mode enable the MB91590 series to operate with low power consumption.
The integrated GDC supports dual displays at a maximum 800×480 resolution, and features a powerful sprite and rendering engine capable of producing sophisticated effects for dashboard applications. It supports 512 sprites sized at up to 512×512 dots each with functions such as automatic blinking, movement, image switching and anti-aliased font display.
Sprite Engine
2-D Rendering Engine and Video Capture
The rendering engine can operate in combination with the video capture and NTSC-decoder functions to enable image manipulation, including zooming and 90-degree rotation. Overlaid graphics such as needles or parking guidelines can also be rendered in conjunction with captured video.
Layered graphical images can be sent to either LCD flexibly.
