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.  
ELECTRICAL SPECIFICATIONS FOR IN-SYSTEM LOADER HARDWARE  
Operating Temperature Range  
0°C to +50°C  
Power Supply Requirements from Target System  
5V @ 100 mA max  
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’s 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:
