Introducing TINI=99
To date, the machinery and the network have remained largely =
separate entities. Embedded microcontrollers have communicated within =
local limits to control lighting, heating and cooling units, doors, =
refrigerators, toasters, and soda dispensers. Bridging the gap to allow =
machinery to talk to the larger network requires a specialized data =
language and improved processing capabilities, without making the bridge =
too big or too expensive. Meet the bridge: TINI.=20

You can Web-enable just about any piece of electrical =
equipment with Dallas Semiconductor's TINI (Tiny InterNet Interface)=97a =
compact circuit board or chip set that incorporates the latest in =
low-cost embedded Java=99 technology. This technology allows you to =
develop Java applications quickly and easily to provide an Internet or =
Intranet interface for your equipment. With a simple Web server =
application, TINI can act as the world's smallest Java Web server. With =
a 1.25 x 3.5-inch form factor and less than 1 cubic inch displacement, =
the TINI interface can fit almost anywhere.=20

As with any true microcontroller, TINI's controller has =
several peripherals integrated on the same chip with the CPU core. This =
high level of integration allows developers to write efficient, =
I/O-intensive Java applications. In typical applications, TINI controls =
and monitors attached equipment and transfers collected control and =
status information over a corporate IT network to client browsers or =
databases.=20

Hardware Capabilities
TINI's three-chip chip set consists of the microcontroller, =
flash memory containing the firmware, and an Ethernet controller. The =
microcontroller, the star performer, integrates serial, parallel, =
1-Wire=99 and Controller Area Network (CAN) ports, with extra pins for =
controlling optional devices such as relays and indicator LEDs. It =
addresses up to 4 MB of RAM and 512 kB flash memory. During boot-up, the =
I/O manager automatically detects the memory configuration, clock speed =
and which hardware peripherals are enabled. This capability allows you =
to flexibly assign memory density and clock speed for optimal =
performance and cost-effectiveness, depending on what kinds of devices =
you're networking.=20

An integrated real-time clock enables time-stamping and =
time-dependent functionality. For security-sensitive applications, a =
physically secure coprocessor with advanced cryptographic capabilities =
is optionally available.=20

System Feature Summary=20

Optimized to accommodate the embedded Java environment, the =
microcontroller supports 24-bit addressing, an 8/32-bit CPU/ALU, and =
high clock rates ~60 MHz, and other Java enhancements. Performance =
improvements in the future will come from progressively greater amounts =
of Java embedded in hardware.=20

a.. 4 MB NV SRAM=20
b.. Real-time clock

c.. Physically secure coprocessor (optional)

d.. Single +5V power supply=20
TINI's I/O ports include:=20

a.. Ethernet 10BASE-T interface=20
b.. Dual 1-Wire net interface=20
c.. CAN interface (with option for a second CAN interface) =

d.. Dual serial port (one RS232 level and one +5V level)=20
e.. I2C port=20
f.. Expansion bus allowing nearly unlimited parallel ports =
and miscellaneous digital and analog I/O=20
Software Platform
The embedded Java is implemented in firmware that is =
programmed in the flash memory and can be upgraded when new releases are =
announced. The firmware includes:=20

a.. The Java VM/API=20
b.. A multitasking Real-Time Operating System (RTOS)=20
c.. TCP/IP networking stack=20
Java VM=20

The Java VM on TINI conforms to Sun's Embedded Java=99 =
platform, version 1.1 of the Java API. Embedded in TINI's flash memory =
are java.lang, java.net, java.io, java.util; there is room in RAM for =
other packages of your choice. Also in flash memory are com.dalsemi =
packages for accessing the TINI command shell (tsh), the 1-Wire bus and =
several system parameters.=20

Software Architecture
Applications: Now and Coming Soon=20

TINI is new but already making network connections with =
different types of devices. For example, a 1-Wire weather station sends =
a Java applet that relays current weather conditions through a TINI =
board interfaced to an Internet server. Result: worldwide access to =
weather conditions local to Dallas. Another TINI board interfaces the =
ballast in a dimmable fluorescent light, allowing individual control of =
office lighting through a Web browser. Both of these TINI applications =
were completed by one Java programmer in less than a week.=20

Other projects still in the works foreshadow the promise of =
networking diverse machines and gadgets with TINI's minimal but =
versatile platform. These include a moving message display, a door entry =
system (www.Lares.com), and vending machines that extract electronic =
cash from iButtons=99.=20

Getting Started: TINI Developer's Kit
While development work continues on multithreading, =
networking and memory management for the Tiny InterNet Interface (TINI), =
Dallas Semiconductor is making available an alpha release of the TINI=99 =
Developer's Kit. This kit will allow you to become familiar with the =
TINI development environment, see code examples that provide a Web =
browser interface to a few simple pieces of equipment, and upgrade in =
the future to new firmware with a more complete expression of the =
standard embedded Java=99 environment.=20

The alpha development kit contains the following:=20

a.. A reference TINI circuit board preloaded with the =
Alpha 1 firmware and an example of user code to provide temperature =
readings from a DS1920 temperature sensor to a Web browser over an =
Intranet.=20

b.. An I/O expansion board providing a parallel port and =
general-purpose I/O lines for prototyping and connecting your system's =
hardware.=20

c.. A serial port adapter and cable for terminal I/O and =
loading new firmware versions or user applications into the TINI board's =
nonvolatile memory.=20

d.. A DS1920 temperature sensing iButton=99 that can be =
used with the preloaded example user application.=20

e.. A modular power supply for connecting TINI to a =
120-volt, 60Hz AC power socket.=20
Software for creating and loading user applications, =
additional example applications, and future firmware releases will be =
downloadable from this Web site or e-mailed to registered users as they =
become available.=20

Release of the beta firmware and a compact production TINI =
board is scheduled for September. The alpha development kit is available =
now to those who want an early experience of the power of TINI and can =
accept the limitations of the existing firmware. You can order the alpha =
TINI Developer's Kit from our online store for $500.=20

And coming soon...
In September 1999, the TINI Board, Model 1, with 512 Kbytes =
NV SRAM, beta release, part number DS22530-512, will be available for =
$50, including software development tools and free firmware upgrades.=20

Dallas is also in the process of developing a single-chip =
TINI implementation, Model 1 beta, containing a DS80C400 CPU chip, flash =
memory chip and Ethernet. Target price will be $15, with availability =
expected sometime in 2000.=20

Meeting Minds: TINI Interest Group
Interested in learning more about TINI? Then join the =
TINI-Java interest group, an e-mail forum where you can network with =
other Java-enabled humans, swap ideas and help lighten the way along the =
discovery process.=20

To join, just e-mail majordomo@iButton.com with the =
following message in the body: "subscribe TINI." Then send your e-mail =
