Power Supply
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.
2.3.1
Power Supply
Sources
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.
2.3.1.1
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

2.3.1.2
External EXT
connector
Note:
Do not mount more than one power supply source on AT89STK-11 Board.
Note:
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.
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:
Do not mount more than one power supply source on board.
Note:
Keep SP1 closed when using the EXT input
2.4
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:
2.4.1
Power-on RESET
The on-board RC network acts as power-on RESET.
2.4.2
RESET Push Button
By pressing the RESET push button on the board, a warm RESET of the microcontroller
is performed.

Tx led is connected to Tx of UART MCU (SP4 jumper can be soldered or not)
ALE led is connected to ALE of MCU
2.5.4
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.
2.5.5
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.
2.5.6
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).
2.6
Interfaces
2.6.1
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.
2.6.2
SPI
The SPI connector is directly connected to SPI I/O of the MCU.
2.6.3
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).
2.6.4
OCD
The On-Chip Debug interface (OCD) is provided on a 6-pin connector.

2.7
Board Settings
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.
The C51 Demo Board has the following settings:

Section 3
ISP Programming
The On-Chip memories and configuration bytes can be programmed using the ISP
mode of the device and Atmel's FLexible In-system Programmer Software (FLIP)
described below.
3.1
Manual ISP Mode
See Section “FLIP Software”, page 11.
3.1.1
Board Configuration
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).
3.1.2
Operating Mode
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.
3.2
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.
3.2.1
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

ISP Programming
3.3
FLIP Software
FLIP software runs on Windows® and Linux® Operating Systems. FLIP supports in-system programming of Flash C51 devices through RS232. The latest version of FLIP
software can be downloaded from the Atmel web site, www.atmel.com.
3.4
Batchisp
Software
Batchisp is an In-System Programming application which can perform the same operations as FLIP but is designed to be launched from the DOS command window.
The main purpose of batchisp is to automate ISP operations on several parts. It may
also be launched from an IDE like Keil's uVision®2 one : you can compile and link your
embedded program, generate the HEX file and download it to the target hardware without leaving the Keil's IDE. This makes embedded software development and test faster.
Autoisp function is an operation which allows to enter in ISP mode without any hardware
handling.This is done thanks to DTR and RTS RS232 signals which can control on the
Board the RST and PSEN I/O of MCU.
