Slim-Link Web Server-Controller
June 2001
Micro-Controller incorporates Web-Enabled, Real-time Operating System
DESCRIPTION
The Slim-Link family of Web Server-Controller products
provides the ideal core technology for Internet enabled
instruments and control systems. The Slim-Link Web Server
Controllers are based on a 40 MHz AMD186ES micro-
controller and feature MicroRTOS, a web enabled, real-time
operating system developed spedifically for control system
applications. MicroRTOS is embedded into each Slim-Link
Web Server-Controller product with no additional cost or
licensing fees.
MicroRTOS
MicroRTOS was created to simplify the process of designing a
web enabled instrument or control system. This is
accomplished by integrating a Preemptive Real-time Kernel,
thin Web Server, and TCP/IP Stack into the fully-functioning
operating system. The designer can then concentrate on the
design of his application rather than integrating source codes
from disparate applications. Three editions of MicroRTOS are
available to support your application; the Basic edition, PPP
Client Edition with Point-to-Point protocol for dial out
applciations and the PPP Server Editon with Point-to-Point
protocol for in bound dial-up applications.
Models
Six models of the Slim-Link
Web Server-Controller are
currently offered. Each model is described below.

INT3
All
INT3 provides the input for Interrupt Request 3 to the to the microcontroller.
23
CLKOUT
AWC86
This output provides the clock signal for the rest of the embedded control system
in the AWC86. Depending upon the value set in the System Configuration
Register of the AMD186 controller CLKOUT can be at 40 MHz, at the Power-
Save frequency, or may be tri-stated. The Power-Save frequency is programmable
from 1/2 (20 MHz) to 1/128 (312.5 KHz) of the system clock
VREF
AWC86A
This input provides the reference voltage for the Slim-Link
Server analog inputs.
VREF should not exceed VCC by more than 50 millivolts.
24
RESETOUT
AWC86
This output provides an active high reset pulse for the complete embedded
control system. The duration of the reset pulse is typically 13 milliseconds. The
reset pulse is sent each time power is applied to the AWC86 or the /RESET
signal is driven low.
V.BAT
AWC86A
This input the battery backup voltage for the AWC86A Real-Time Clock. A
minimum of two volts must be maintained on VCC1 to maintain the Real-Time
Clock.
25
/RESET
ALL
This input allows an the Slim-Link
Server to be reset from an external source.
Reset must be held low for a minimum of one millisecond to initiate a Slim-Link
Server reset.

DGND provides the reference ground for the Slim-Link
Server's Digital I/O
signals.
27
