Power Supply
The on-board power supply circuitry allows various power supply configurations.
Power Supply Sources The power supply source can come from two different and exclusive sources: either from J4, JACK PWR connector either from J5, 9V (Battery connector) J4 - JACK PWR connector: - Need of a male JACK outlet - Input supply from 6 up to 15V DC
AT89STK-06 Demo Board User Guide
Rev. 4339B-CAN-11 / 04
Hardware Description
- No specific polarization mandatory Note: There is a diode voltage level between the negative output of the power supply and the "GND". This could introduce some gap of voltage during measurement and instrumentation.
Figure 2-2 . Male JACK Outlet and Wires + -
Caution: Do not mount more than one power supply source on AT89STK-06 board. J5 - 9V Battery connector: - Need of a female 2 points connector - Input supply from 6 up to 10V DC (example: 9V battery) - Polarization mandatory

Caution: Do not mount more than one power supply source on AT89STK-06 Starter Kit.
RESET
Although the AT89C51CC03 & AT89C51AC3 microcontrollers have on-chip RESET circuitry (c.f. microcontroller datasheet), the AT89STK-06 board provides to the microcontroller a RESET signal witch can come from 2 different sources: The on-board RC network acts as power-on RESET. By pressing the RESET push button on the AT89STK-06 board, a warm RESET of the microcontroller is performed.

Hardware Description
Serial Interfaces
RS-232C All CAN microcontrollers have one on-chip UART peripheral. Only the asynchronous mode is supported by the AT89STK-06 board. The AT89STK-06 board is supplied with a RS-232 driver / receiver. Only one female DB9 connector assumes the RS-232 connections. A full range of configuration can be set with two Rx lines and two Tx lines. Figure 2-4 . RS-232 DB9 Connections

Hardware Description
The microcontroller is a microcontroller with an on-chip full-CAN controller. The AT89STK-06 board is supplied with an Atmel CAN transceiver (ATA6660). A female DB9 connector assumes the CAN bus connections. Figure 2-7 . CAN DB9 Connections

Section 3 Device Programming
In-System Programming
Manual ISP Mode Board Configuration
The on-chip memories and configuration bytes of the AT89C51CC0x parts can be programmed using the ISP mode of the device.
To use ISP mode, the board should be configured as follow: POWER switch (SW1) on "ON" position EA jumper should be open (internal code execution only). Before using ISP mode for T89C51CC02 or T89C5115 device, be sure to close SP1 solder pad ( See Section "T89C51CC02 / T89C5115 Support (SP1)", page 8).
Operating Mode
To enter in ISP mode, press both the RESET (SW5) and ISP (SW4) buttons simultaneously. First release the RESET button and then the ISP button. The device enters in ISP mode.
Auto ISP Mode
The Auto ISP is available only for parts with UART bootloader (-UA devices). It allows the host PC application (Atmel FLIP software for example) to control the hardware conditions from the serial lines RTS and DTR. Thus with the Auto ISP mode, the user does not need to push the ISP and RESET buttons.
Board Configuration
To use Auto ISP mode, put the board in the same configuration as ISP mode and also: Close RTS (JP4) jumper Close DTR (JP5) jumper
