MB91590 Series
32-bit MCU with Integrated Graphics Controller SoC
Description0
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.
The integrated GDC supports dual displays at a maximum
800×480 resolution, and features a powerful sprite and ren-
dering 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. The
rendering engine can operate in combination with the video
capture and NTSC-decoder functions to enable image manipu-
lation, 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.

Key Features0
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.
