Fujitsu's High-Performance MB9BF500/400/300/100 Series
operates at 80 MHz, with up to 512 KB high-speed flash memory and up to a 64 KB
SRAM. The MCUs in the series are capable of supporting USB, CAN, UART, SIO, I2C
and LIN communications protocols and are available in LQFP120, LQFP100, QFP100
and BGA112 packages.
The Basic MB9AF100 Series includes limited versions
of the advanced peripheral functions of the High-Performance Series, is
optimized for use primarily in major home appliances, digital consumer devices
and office automation devices. The Basic Series devices operate at 40 MHz,
support up to 256KB high-speed flash memory and up to 32KB SRAM and are
available in LQFP120, LQFP100, QFP100, and BGA112 packages.
The FM3 MCU
family incorporates the peripheral features of the Fujitsu FR microcontrollers
along with additional
peripheral macros specifically for high-precision motor control, such as three
independent 12-bit A/D converters (+/-2LSB 1.0Î¼s conversion). With support for
up to 16 channels, the A/D converters provide positional accuracy and
fine-tuned motor control for factory automation applications, such as
high-precision and high-speed servo motors. A positional sensing counter
monitors motor rotation, providing automatic hardware-based detection, which
minimizes the CPU workload and reduces the amount of power consumed by inverter
The FM3 MCU family supports a wide voltage range
from 2.7 to 5.5V with a single power supply.
The Fujitsu FM3 MCU family is useful for factory automation
systems and basic home appliance
applications like air conditioners, refrigerators, and washing machines, along
with digital consumer devices and office automation equipment.
The fun factor continues to draw developers to Linux. This open-source system continues to succeed in the market and in the hearts and minds of developers. Design News will delve into this territory with next week's Continuing Education Class titled, “Introduction to Linux Device Drivers.”
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
