Fujitsu Semiconductor Asia Pte Ltd has launched six products in the MB91590 series of system controllers for instrument clusters using color displays in automotive dashboards and onboard information displays of the center consoles. It also reported the forthcoming release of two products in the MB91570 series of MCUs for segment-display dashboard panels.

As advanced vehicle electronics are being deployed as new control systems for hybrid and electric vehicles, the trend towards higher performance and increasing integration of functionality in these control units is expected to continue. These systems require high-performance system controllers that can respond to information coming from a variety of peripheral components in real time and that can display this information using rich graphics. The need to display video is also expected to grow as onboard cameras are increasingly being used for improved safety.

The six new products in the MB91590 series target these needs in applications for dashboards and other human-machine interface systems in automotives. They are single-chip system controllers that integrate the FR81S CPU core with a graphics-display controller that has outstanding sprite functions, video capture to input from exterior video signals, and communications functions, including CAN and LIN.

To ensure that developers can work these products into their designs with minimum difficulty, Fujitsu Semiconductor is offering a starter kit, sample programs, a graphic-design tool that allows designers to try out screen designs visually, and a graphics library.

Product features

The FR81S high-performance 32-bit CPU core runs at 128MHz. It has a CAN embedded MCU and a single-precision floating-point unit for filtering and other high-speed image processing, as well as a memory-protection unit that can guard access to regions of memory. To make the most of the CPU's performance, it includes EcoRAPID, a new macro for NOR flash memory, along with faster and low-power MCU operations.
