AL220 Analog-in, Analog-out Microcontroller

* Processes fuzzy logic technology directly in hardware
* Reconfigurability for easy design changes
* New development system for notebook development

San Jose, Calif., August 28, 1995 - Adaptive Logic today introduced a
one-chip reconfigurable microcontroller that provides dedicated, stand
alone control using fuzzy logic technology. At the same time, to support
the AL220, Adaptive Logic is introducing INSiGHT IIe, Windows-based,
state-of-the art development tool for design development, simulation,
real-time emulation and programming.

The AL220 analog microcontroller with fuzzy logic on chip allows the
designer to design the device directly into analog control loops with no
additional components. It delivers a one-chip hardware alternative to the
cumbersome solution of embedded microcontrollers utilizing separate fuzzy
logic software. The deficiencies of the traditional microcontroller and
software solution include higher cost, slower speeds, complex design and
generally are not reconfigurable.

The INSiGHT IIe Windows-based development tool provides the key to ease of
design because you program the AL220 using fuzzy-logic rules instead of an
algorithmic programming language. So the designer can focus on solving the
application rather than writing lines of code. INSiGHT IIe improves design
debugging through an equation editor. INSiGHT IIe also features real time
hardware emulation.

"The AL220 microcontroller can be viewed as an analog PLD or a smart analog
solution to programmable logic types of applications," stated Chuck
Bellavia, Adaptive Logic Vice President of Sales & Marketing. "And it has
all of the same inherent advantages: desktop design and programming,
reconfigurability, easy to design, but with a small price tag. This all
results in shorter design cycles so engineers can get products out on time
and within budget constraints."

Applications

Analog microcontroller applications include temperature control motion and
position control power management and smart analog applications, among
others. Recent design wins have included intelligent battery charging,
automatic gain control and closed loop process control.

AL220 Features

The AL220 provides a patented FLOATING MEMBERSHIP function allowing
calculation of derivatives and eliminating the need for look up tables.
Four analog inputs are processed through the core to control four analog
outputs. On-chip A/D and D/A converters give the designer a unique
one-chip solution.

Devices are available in 18-pin DIP and 20-pin SOIC EEPROM packages.

INSiGHT IIe Features

With INSiGHT IIe, designers have the freedom to use real-language rules
rather than algorithmic programming languages, and they can program the
chip directly on the INSiGHT IIe programmer. The equation editor makes it
easy to define all the input-variables, and interactive I/O allows
closed-loop system simulation to minimize the frustration of debugging.
Any input, output, variable, or rule can be set to a constant to isolate
and debug problems quickly. INSiGHT IIe also provides notebook development
and real time hardware emulation via a parallel port.

Cost and Availability

The AL220 is available in September and INSiGHT IIe is available now. Cost
for both the development system software and emulator programmer is $595.

The 18-pin, DIP programmable versions of the AL220 will cost $1.90 in
volume. Single unit prices for the 20-pin SOIC and 18-pin DIP EEPROM used
in development is $7.50.

About Adaptive Logic

Adaptive Logic's mission is to produce practical microcontrollers utilizing
fuzzy logic technology to improve the performance, ease of use and cost of
consumer and industrial products. Having introduced semiconductor devices
that perform fuzzy logic calculations directly in hardware, Adaptive Logic
remains the only supplier of dedicated, single-chip controllers and other
devices using fuzzy logic. Fuzzy logic is a new, powerful processing
methodology that incorporates intuitive reasoning, and takes into account
the degree to which something is true. The technology is used in a variety
of innovative applications, including battery chargers, home appliances,
heaters, thermostats and motion controllers. Adaptive Logic, a private
company, was founded in February 1991. The company is located in Silicon
Valley at 800 Charcot Ave., Suite 112, San Jose, CA 95131; Phone:
