3 I. Overview This user s manual will guide you on how to use the ALEXAN Training Module (TM-). The TM- is a helping tool in which you can explore the many features of a microcontroller. This module uses ATMEL AT89C05 and AT89C405 microcontroller (MCU). This training module has the following applications:. -External Switches INT0 (P.),INT (P.),T0 (P.4). 7-Segment Display. Buzzer 4. LEDs 5. Relay 6. RS Serial Communication You must first be familiar with and understand the schematic diagram of the training module to facilitate your programming. Alexan 05/405 TM- v..0 Page of 7

4 II. Getting Started What you need to get started. 05 Training Module-. 6 to 9V DC Power Adaptor. ATMEL AT89C05/AT89C405 Microcontroller 4. -Pin Connector to Serial Connector for RS 5. ATMEL Programmer 6. Debugger/Compiler for your source code After writing your hex code into the microcontroller by means of an IC programmer, insert your microcontroller into the 0-pin IC socket of your training module. Note: The notch of the IC socket must correspond to the notch of your MCU. Incorrect placement may damage your MCU. Move the jumper of SEL to select between LED display and 7-segment Display (both are connected as Common Anode). Likewise, move the jumper of SEL to select between Buzzer andrelay application (a 0 or LOW pulse is used to activate buzzer and relay). If you want to use the digits of your 7-segment display, you can enable/disable the transparent latch IC (74LS7). Alexan 05/405 TM- v..0 Page 4 of 7
