MB88F322 Graphics Display Controller
Description
The Fujitsu MB88F322 Graphics Display Controller (GDC)
is an extremely versatile and feature-rich device that has been
designed specifically for today’s most popular display-based
automotive applications including instrument clusters,
Heads-Up Display (HUD), Central Information Display (CID)
and Rear-Seat Entertainment (RSE) systems. Packaged in a
low-cost 208-pin Quad-flat package (QFP), this device has a
number of advanced on-board features that significantly
reduce bill-of-materials cost, form factor and system-level
power consumption.
Perhaps most significantly, the sprite engine does not require
the expensive frame-buffer memory that is necessary for
graphics rendering units. This device uses a simpler and
far-less-costly line-buffer technique that is commonly used
in high-definition video products. Accordingly, the on-chip
memory space is more than adequate to support an array
of bit maps and sprites that are typical in automotive
applications. For larger content, such as splash screens, the
device features run-time data compression for expansion of
run-length encoded data.
The MB88F322 GDC is principally a sprite engine that is
optimized to efficiently process and animate sprites and
bitmaps in a variety of sizes and color depths. The absence of
a traditional 2D/3D rendering engine enables this device to
operate at a lower frequency. This translates into reduced
power consumption, improved EMI characteristics and an
extended operating temperature range of -40°C to +105°C.
The MB88F322 GDC advanced image-processing system
supports 1-, 2-, 4-, and 8-bit indirect color palettes. For
applications that require finer gradient coloring, the device
also supports 14- and 16-bit direct color modes. An available
4/8 bit alpha plane and dithering-and-gamma unit ensure high
image quality. The display controller supports a variety of
display sizes with resolutions up to 800 x 600 and color depths

of 8-, 16- and 24-bits. An integrated programmable timing-
control unit (TCON) enables the device to directly interface
with display column and row drivers, improving the level of
compatibility while reducing overall system cost.
Another feature of the MB88F322 GDC is that it is a
traditional 5-volt device, allowing the inclusion of on-chip
stepper motor controllers (SMC). The MB88F322 GDC
includes six SMCs, making it ideal for use in amalgam clusters
that feature both TFT and traditional mechanical gauges.

On-chip pulse width modulators (PWM), ADCs, I C, UARTs,
and a sound generator are also integrated onto the
MB88F322 GDC. This allows the device to control all the
peripheral functions, including backlight circuits, LEDs,
sensors and on-board communication, in a display sub-system.
With so much functionality packed into one chip, combined
with the elimination of frame-buffer memory, MB88F322
designs can be deployed on low-cost, two-layer PCBs with a
minimum of external components.
