2.2 Power Supply The on-board power supply circuitry allows various power supply configurations.
2.2.1 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

– 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
Figure 2-3 . EXT PWR Female Connector / Cable for 9V Battery
Caution: Do not mount more than one power supply source on AT89STK-06 Starter Kit.
2.3 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:
2.3.1 Power-on RESET The on-board RC network acts as power-on RESET.
2.3.2 RESET Push Button By pressing the RESET push button on the AT89STK-06 board, a warm RESET of the
microcontroller is performed.

2.4 Serial Interfaces
2.4.1 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.

2.4.2 CAN 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
If a network termination is needed, JP3 switch inserts a 120Ωresistor between CAN-H
and CAN-L.
A red LED indicates a TxCAN traffic, a green one indicates a RxCAN traffic.
Figure 2-8 . CAN LEDs
2.4.3 SPI The AT89C51CC03 in PLCC52 is a microcontroller with an on-chip full duplex SPI
interface, master or slave.
A 6-pin male connector assumes the SPI bus connections. The SPI 6-pin connector also
provides to the user Vcc and Gnd.

2.5.2 Solder straps Solder straps allow to modify the board configuration for specific usage such as
T89C51CC02 compatibility.
Figure 2-11. Solder Strap definition
2.5.2.1 T89C51CC02/T89C5115
Support (SP1) When using T89C51CC02 or T89C5115 products with the AT89STK-06 board ( see ¨PLCC adapter for T89C51CC02 user guide: CANADAPT28), the SP1 solder pad
should be closed to ensure correct hardware conditions setting on P1.0 port.
SP1 solder pad connects ISP push button to P1.0 microcontroller port and the
CANADAPT28 adapter should be inseted in U2 (PLCC44) socket.

Device Programming
3.1 In-System
Programming The on-chip memories and configuration bytes of the AT89C51CC0x parts can be pro-
grammed using the ISP mode of the device.
3.1.1 Manual ISP Mode
3.1.1.1 Board Configuration 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).
3.1.1.2 Operating Mode To enter in ISP mode, press both the RESET (SW5) and ISP (SW4) buttons simulta-
neously. First release the RESET button and then the ISP button. The device enters in
ISP mode.
3.1.2 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 con-
ditions 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.
3.1.2.1 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
