Graphics controller provides in-car
information
The MB88F332 optimises the bill-of-materials for cluster and other display-based systems by eliminating the need for external memories.
Fujitsu Microelectronics Europe (FME) has expanded its graphics controllers family with the MB88F332 - a highly integrated single-chip graphics solution for automotive display systems The MB88F332 is optimised for in-car-applications such as cluster instrumentation (especially hybrid clusters), head-up systems and central information displays

Leo aims at European navigation applications
Fujitsu Microelectronics Europe is releasing its Leo FR-V (Fujitsu RISC-VLIW) chip, based on the FR-V architecture announced last year.
In this type of application, this new cost-effective controller acts as a single-chip unit where the APIX link is used in combination with a sophisticated sprite-engine for high-quality graphics generation.
A key feature of the MB88F332 is the APIX serial gigabit interface from Inova Semiconductors.
Fujitsu is the first silicon vendor on the market to integrate this new video interface into a portfolio of microcontrollers and graphics controllers.

Fujitsu Microelectronics Europe and UNIS have introduced the Flash-kit programmer, a high-speed, in-system programming solution for all Fujitsu Flash microcontroller families.
Low-power dual PLL frequency synthesisers
A new series of dual phase-locked loop (PLL) frequency synthesisers designed by Fujitsu feature extremely low power consumption, fast lock times and ultrasmall packaging.
Automotive peripherals such as stepper motor controllers, pulse width modulators, ADCs, I2C, UARTs and sound generator are also integrated onto the MB88F332.
This allows the device to control all the peripheral functions in a display sub-system.
Typical applications for these interfaces include driving dashboard gauges, backlight circuits, LEDs, sensors and on-board communication.
The MB88F332 optimises the bill-of-materials for cluster and other display-based systems by eliminating the need for external memories.
The graphics processing is based on a line-buffer principle, which eliminates the need for expensive (internal or external) frame-buffer memory.
In addition, integrated Flash memory can be used to store a set of sprites without any additional external devices.
Direct display connection via RSDS or RGB, 5V automotive interfaces and an analogue front-end for the APIX link are also included to reduce system costs.
The built-in graphics engine can generate up to 512 sprites from 4 x 4 up to 512 x 512 pixels in size.
Sprites can be animated and can be stored in a variety of colour modes (direct and indirect colour formats).
Alpha blending is possible between several graphic layers and overlapping sprites.
The graphics engine is controlled via command lists, which allow pre-loaded sequences of actions to be triggered automatically.
The MB88F332 can be freely programmed for panels from 320 x 160 up to 1280 x 480 pixels resolution.
A built-in TCON unit allows panels to be attached without the need for further controller logic, which is a significant cost benefit.
A signature unit for security and dither and gamma units for picture quality optimisation are available as well as layer blending and automatic fade-in/out.
The physical interface to a display panel can be RGB digital or RSDS.
With its embedded memories, automotive I/Os, inexpensive QFP-package and extended temperature range of -40 to +105C, the MB88F332 requires no other components and reduces system costs. Request a free brochure from Fujitsu Microelectronics Europe ...
