Power Supply
Power Supply Sources
The on-board power supply circuitry allows various power supply configurations. This gives the user the capability to power the devices in the 3V and in the 5V voltage range. The power supply source can come from two different and exclusive sources: either from the JACK PWR connector either from the 2-point sip EXT connector.
JACK PWR Connector
The Jack power connector implemented on board is a female Jack connector with internal 2.1mm conductor. It requires a male JACK outlet with 2.1mm capability. No specific polarization is mandatory as on-board diode rectifier gives a protection against inadvertent polarization invertion. When using the JACK power supply, the board is powered with a 5V voltage.

Hardware Description
Figure 2-3. Male JACK Outlet and Wires
Note: Note:
Do not mount more than one power supply source on AT89STK-11 Board. There is a diode voltage level between the negative output of the power supply and the "GND". This could introduce some voltage gap during measurement and instrumentation.
External EXT connector
The battery power connector implemented on board is a male two point SIP connector. It requires an external power cable with a female 2 points connector. When powered though this interface, polarization is mandatory as no protection is given on board. The EXT power supply circuitry support input supply from 2.7V up to 5.5V DC. Figure 2-4. EXT PWR Female Connector / Cable
Note: Note:
Do not mount more than one power supply source on board. Keep SP1 closed when using the EXT input
Reset
To be compatible with Atmel microcontrollers which have (or not) its on-chip RESET circuitry (c.f.microcontroller datasheet), the board provides 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 board, a warm RESET of the microcontroller is performed.

Hardware Description
Features
Push-Buttons
This section presents the various features such as leds, buttons, etc.. available on the board. RESET can be used to apply warm reset to the MCU ISP can be used with RESET to apply hardware conditions resulting in bootloader start INT0 push-button can be used to activate INT0 input INT1 push-button can be used to activate INT1 input
User Push buttons
PB0, PB1, PB2 and PB3 are four push-buttons available for user application They are made available on a 6 pins socket and in the expansion area so user can use them according to the application needs.
Indicator LEDs
PWR led is driven by input of voltage regulator Rx led is connected to Rx of UART MCU (SP3 jumper can be soldered or not) Tx led is connected to Tx of UART MCU (SP4 jumper can be soldered or not) ALE led is connected to ALE of MCU
User LEDs
LED0, LED1, .. LED7 are height leds available for user application They are made available on a 10 pins socket and in the expansion area so user can use them according to its application needs.
Ports
Port 0 and Port 2 are made available on two 10 pins sockets to ease user interconnection to the MCU. The are also available on the expansion area.
Clocks
An external clock can be connected to the board to control externally XTAL1 input clock of MCU by using the XTAL1 from the expansion area. In the same way, another external clock can be connected to control externally the PCA clock (P1.2 / ECI).
Interfaces
TWI The TWI connector is controlled by hardware TWI I / O of MCU (for Product including this feature). The signals sda and scl are controlled by the TWI ports of MCU. This TWI bus is also connected to the expansion area. External TWI pull-ups are not provided on the AT89STK-11.
The SPI connector is directly connected to SPI I / O of the MCU.
RS-232
The DB9 connector is connected to on-chip UART peripheral through a standard RS232 driver / receiver. Two leds are provided to indicate activity on Rx and Tx lines (They can be disconnected removing solder pad SP3 and SP4).
The On-Chip Debug interface (OCD) is provided on a 6-pin connector.

Hardware Description
This interface enables the debug of the application through ATMEL OCD dongle for AT89C51RE2 / IE2 / RD3 / IE3 only.
Expansion Area
In addition to a 16x29 pad array, two rows of pads are given on the right side of the board to offer all the MCU signals tu user application. Any application expansion can be built on board through this interface.

Section 3 ISP Programming
Manual ISP Mode
See Section "FLIP Software", page 11.
Board Configuration Operating Mode
To use ISP mode, no specific configuration is necessary on the board. Only make sure that the EA pin of the product is tied to Vcc (internal code execution only). To enter in ISP mode, press both the RESET and ISP buttons simultaneously. First release the RESET button and then the ISP button. The device enters in ISP mode.
Auto ISP Mode
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 (J11) jumper Close DTR (J12) jumper
