DS5000TK
Microcontroller Evaluation Kit
www.dalsemi.com
DESCRIPTION
The DS5000TK is a development support system which
allows immediate evaluation of the DS5000(T) Soft
Microcontroller Module. It can also be easily modified to
work with the DS2250(T) and DS2252T Microcontroller
module as described later in this document. Materials
provided with the kit include a DS5000T with 32
kilobytes of RAM, In-System Loader hardware, KIT.EXE
evaluation kit software, demonstration software, and full
documentation on the DS5000 and DS5000T. With the
Evaluation Kit, the user can quickly configure the
DS5000T for operation in the target system without detailed knowledge of the operation of the DS5000's
bootstrap loader interface. The DS5000TK Evaluation Kit not only serves as a first-time evaluation
system for the DS5000 or the DS5000T, but also performs the equivalent function of an EPROM
programming system throughout the prototyping phase of the design cycle.
The software diskette supplied with the Evaluation Kit includes KIT.EXE as well as utilities that allow
you to read/set the date and time in a system using a Soft/Secure microcontroller and time in your PC. See
the README.TXT file included on the disk for more information.
SYSTEM REQUIREMENTS
The DS5000TK Evaluation Kit requires a PC or compatible with at least 128 kilobytes of free memory.
KIT.EXE has been tested under DOS, Windows 3.x, and Windows 95. The hardware requires an RS-232
port on the PC for communication with the RS-232 fixture.
The DS5000TK hardware requires external power to operate. Power (+5V, GND) must be applied to VCC
and GND pins of the target cable of the RS-232 fixture. Failure to do so will result in a "Cannot talk to
Kit" or "Prompt not seen" message. A user-selected crystal must be attached to appropriate target cable
pins if code is to be run by the DS5000TK hardware.

IN-SYSTEM LOADER
The In-System Loader hardware allows application software to be loaded into the microcontroller while it
is connected to the target system, eliminating the need for removal of the device when reprogramming is
required. It consists of an RS-232 fixture with a 40-pin socket for the microcontroller, with cables to
attach it simultaneously to a PC communications port and the microcontroller鈥檚 target system. The
hardware provides the mechanism for the KIT.EXE software to take control of the microcontroller via the
RS-232 cable, place the device in its Serial Program Load Mode, and upload or download code or data to
the device. The main components of the In-System Loader hardware are described in detail below:
