Introduction
1 INTRODUCTION
The ST624x Starter Kit provides you with all you need to start designing, developing and evaluating programs for ST624x microcontrollers immediately.
The ST624x Starter Kit includes:
• The ST6 assembler and linker, AST6 and LST6.
• The ST6 Windows debugger, WGDB6.
• The Windows ST6 microcontroller programmer, Epromer.
• The ST6 Starter Kit board, w hich serves as a demonstration board and low-cost debugging tool.
• Some demonstration programs that show how ST6 microcontrollers use the Starter Kit
board resources.
• Some example programs.
• Two ST62E46BF1 microcontro llers.
• A complete set of paper documentation and online help.
The demonstration programs, that come pre-loaded on the ST62T40B microcontroller, show
how the powerful features of ST6 microcontrollers operate in a real environment. The demonstration programs use the hardware resources provided on the Starter Kit board, which include an LCD, hexadecimal keyboard, a resistance trimmer and an 8 MHz and a 32 KHz oscillator.
Using the ST6 assembler and linker, AST6 and LST6, you can assemble and link ST6 programs. The "ST6 Family Software development tools AST6, LST6, WGDB6" User Manual will
guide you through the steps of developing, assembling and linking programs for the ST6. The
Starter Kit software includes a set of example programs of typical ST6 applications. These are
installed in the directory C:\st6tools\sk624Xi1\examples.
For a fast-track solution for developing bug-free programs for the ST6, without the hassle of
writing assembler code, try out the ST6-Realizer program.
Once you have developed your ST6 program, you can use the Windows-based ST6 program
debugger, WGDB6/SIMULATOR, together with the Starter Kit board, as a low-cost but powerful debugging tool. WGDB6 includes an ST6 simulator, that simulates the execution of your
program, and uses the ST6 that is plugged into the Starter Kit board to emulate all transactions that are performed with the data space. Thus, using the Starter Kit board with WGDB6,
you can view how the microcontroller peripherals behave when your program is executed.
WGDB6 includes powerful debugging features, such as source-level debugging, instruction
and conditional memory access breakpoints and selective trace recording. The "ST 6 Family

Introduction
Software development tools AST6, LST6, WGDB6" User Manual and online help will lead you
through the debugging process using WGDB6.
When your program is ready, Epromer provides you with an easy-to-use Windows interface,
which lets you prepare executable code, then write it to the ST62E46B microcontroller that
can be plugged into the SDIP56 ZIF socket on the Starter Kit board, or your own in-circuit application board that is connected to the Starter Kit board.
The ST62T40B can’t be erased or programmed, it is already programmed and contains the
demonstrations program.
To observe and evaluate the consequences of your program on the resources it controls, you
can run it on the ST62T40B microcontroller that is s oldered on the Starter K it board in Hardware Simulation mode. If it controls a resource that is not included on the Starter Kit board,
you can connect your own resource to the board.
Instructions for use - Warning

2.3 8 MHz and 32 KHz Oscillators
An oscillator feeds the ST62T40B OSCIN input with an 8 MHz clock signal.
A 32 KHz oscillator is delivered with the boar d. The required components: crystal XT1 and ca-
pacitors C5, C6 are connected to the ST62T40B as described in the ST6240 Data Book.
2.4 8-alphanumeric Digit LCD
An 8-alphanumeric digit LCD is connected to the ST62T40B LCD driver outputs. It has 32 segments that are driven by 4 COM outputs. You can disconnect a part of the LCD by removing
jumper JP2 if you want to use the combi-port PC0-7 on the connector interface J2. For full details about the LCD see “LCD Interface” on page 36.
2.5 Reset Button
This activates the ST62T40B RESET input when pressed. A power-on reset circuit is also provided.
2.6 LED Indicator
A LED is connected to the ST62T40B PB4 I/O pin (which is defined as output) to demonstrate
the ST6 LED-driving capacity. It can be disconnected from PB4 by removing the jumper JP3.
2.7 Hexadecimal Keyboard
A hexadecimal keyboard is connected to the ST62T40B PB0 I/O pin (defined as A/D Converter input), via an analog interface resistor array.
The voltage value on the A/D converter input is equal to 5V/16 x the key number, thus giving
an image of the pressed key.

The Starter Kit Hardware
The following table lists the Resistor array values and their corresponding voltage/key values:
Jumper JP5 sets the keyboard operation mode: polling or IRQ, according to the following diagram.
Jumper JP4 disconnects the keyboard output from PB0 when it is removed, enabling you to
connect your own external source to PB0 via the J1 connector.
For an example of the analog keyboard application, refer to the SGS-Thomson application

2.8 Resistance trimmer
A 10 KΩ resistance trimmer feeds the ST62T40B PA4 I/O pin (when programmed as an A/D
Converter input) with a variable voltage (0 to 5V DC). It is used for A/D conversion demonstration/evaluation.
The trimmer can be disconnected from the PA4 I/O pin by removing the JP6 jum per.
2.9 Combi-ports PC0-7
The port C of the ST6240B is used for the LCD segments. It can be used as a normal port in
hardware simulation mode.
The port PC0-7 can be accessed on J2, prior to use it, remove the 8 jumpers on JP2 (marked
14 on the Starter Kit board diagram on page 11). Thus, the LC D won’t be aff ected by the inputs on the port PC0-7 and won’t be damaged.
