AT89SXX ISP Flash Programmer v1.4 Amit Sengupta Introduction Welcome to the world of Microcontrollers, and the first thing you need is a Device Programmer. This In System Programmer is RS232 (serial port) based but can indirectly be used with USB using USB to RS232 converter. If you need something like this you need to assemble a very simple circuit (Programmer Unit). Hardware Figure 1 shows the Block diagram of the in-system programmer interface, the programmer can be self powered or target powered it depends on how you plan to use it. Figure 1: Block Diagram of the ISP Programmer Figure 2 shows the actual circuit diagram.
The Programmer has just two ICs. IC1 = AT89C2051, IC2 = MAX 232. Few Resistors, LEDs, capacitors etc. The value of the crystal is critical and must be 11.0592 MHz. Figure 2: Circuit Diagram of the ISP Programmer Firmware.
Assemble the circuit and burn the firmware into an AT89C2051(you will need a conventional parallel Programmer to Program the AT89C2051). Software The Software is a Windows GUI application and supports all programming functions. When you run the software for the first time it looks for a valid programmer on COM1. If the Programmer is connected to say COM2 you will receive an error message but when the application starts select Options-Settings on the Menu and specify the correct COM Port. Following are the main features of this software,. Device Supported - AT89S51, AT89S52, AT89S8252, AT89S8253. Read and write Intel Hex files.

Dontronics - Peter Averill's Atmel AT89C2051 Programmer. Direct to: or Peter Averill's Atmel AT89C2051 Programmer. 1-Nov-2001 Sorry, this page is a little out of date, as the DT206 board is no longer available. Parallel Printer port 2051 programmer.
This new schematic shown at the bottom of this page is the basis of, a new 2' SimmStick board, which mates with the Printer Port front end. 31-Mar-1999 It has been found that the AT89C4051 chip can't be programmed with the DT206 programmer for some reason. The second address doesn't verify. This is using both the BASCOM series software and the Peter Averill software. 21-May-99 is a new driver and suggestions from Peter Averill regarding the programming of the AT89C4051 chip. We aren't saying that all the problems have been solved, but look forward to user feedback on this one.
From: Peter Averill To: 'dontronics.com' Subject: 2051 programmer Date: Thu, 7 Aug 1997 07:50:29 +1000 Don, Here is the latest 2051 programmer software. There is no change to the circuit that I gave you. I have tested the program on a Pentium 100MHz and it worked fine. This latest program reads the parallel port address from the bios, so it should work on your notebook. As I said the other day this cct and program are free to all, so distribute as you feel. If you run the program for the 1st time on a new disk it won't find it's configuration file, just go to 'select printer port' and one will be created.
Regards Peter All feedback please to: Date: Mon, 16 Feb 1998 16:15:12 +1100 (EST) To: dontronics.com From: [email protected] (Peter Averill) Subject: 2051 programmer pcb layout Don, Here are the layout and overlay files for the 2051 programmer. They are both GIF files. Both files display very large if you view them using a browser (eg I use Netscape) however they print to scale using GWS or a photo editor program printing to a 300 dpi printer.
The DB25 connector mounts onto the side of the board. That is, one row of pins on the bottom and the other on the top. The top row of pins have nothing to connect to. The constructor needs to connect 4 wires to the pins shown on the overlay. The rest of the construction is straight forward and shouldn't present too many difficulies to most people.
Regards Peter Date: Wed, 1 Apr 1998 20:37:39 +1000 (EST) From: [email protected] (Peter Averill) Subject: Latest 2051 programmer software Don, Here is the latest version of the software for the 2051 programmer. It now accepts HEX files directly. I have answered a number of emails recently and promised this update, so you may like to indicate that this is the latest version. The files include a monitor program for the 2051 that uses your DT104 & DT203 boards. Regards Peter Subject: Latest 2051 programmer software Date: Mon, 3 Aug 1998 16:35:18 +1000 (EST) From: [email protected] (Peter Averill) To: dontronics.com Don, Here is the latest copy of the 2051 programmer software.
I have promised this update to a couple of people who have emailed me re: a small problem. 3-8-98 The latest versions of the 2051 programmer software are as follows htobv2.exe clpgmv2.exe pgmv21.exe All of these programs have a fix in them for a problem that has occured using the Franklin 'C' compiler. The Franklin compiler creates HEX files that contain records out of address order. The first record might be for address 008Ah and then the next record might be for address 0051h. The older versions of the above programs can't handle this situation. The Franklin compiler is the only software that I have found that does this but there seems to be a fair number of people using it. Htobv2.exe can now handle records in any order up to the maximum file size of 64K.
The other two programs obviously have a 2K limit for the 2051, but once again can now handle records in any order. At this stage I have not included support for the new 89C4051, as I have not obtained one yet for testing.
Regards Peter Please Note. The original PCB artwork that Peter supplied doesn't match the schematic below, as he has simplified the power supply logic section, however the changes are mainly to do with getting rid of the pots and finicky adjustments that were required and outlined in the software download files.

At89c2051 Clock Kit
You cannot download your hex files to the part, they have no onboard bootloader. They need to be programmed with a programmer that manipulates and controls the processor pins directly. You need to buy a programmer, download your.hex files to the programmer and tell the programmer to program the part. Then you remove it from the programmer and insert it into your board. The ATMEL website has an excel file which lists all the different vendors that make programmers. Some of them are pricey, a BP microsystems programmer is about $6000.00.
Dontronics - DT206 AT89C2051 and SPI Flash Programmer. Mates with DT004 board.
DT206 AT89C2051 and SPI Flash Programmer. 30-Jun-2002 Sorry, this product is now obsolete. Mates with DT004 board. The DT206 is on a 2 Inch Simmstick platform.
This is the for the AT89C2051 programmer and the SPI Flash Programmer which was originally designed by Jakub Jiricek 31-Mar-1999 It has been found that the AT89C4051 chip can't be programmed with the DT206 programmer for some reason. The second address doesn't verify. This is using both the BASCOM series software and the Peter Averill software. 21-May-99 is a new driver and suggestions from Peter Averill regarding the programming of the AT89C4051 chip. We aren't saying that all the problems have been solved, but look forward to user feedback on this one. 25-May-99 From: Barry Hay spam suppressed @nomadic.com.au Don, I've been absent for a while, but just today noticed a comment on your site saying that 89C4051s could not be programmed with DT206. I don't understand - I have been happily programming 89C4051s using DT206 and BASCOM-8051 for some time now, once I resolved a Parallel port problem I had.
Overview: The DT206 has been designed as a multi purpose board. It is basically two programmers on the one board and was designed to mate with the Dontronics board which connects to a Printer Port, however this isn't mandatory as a printer port front end can be built up very easily by the user. It can easily be configured for AVR programming as well. SPI Flash Programmer: In the top right hand corner of the board, there is a simple SPI Programmer using a single 74HCT126 chip.
This has a 16 pin SPI programming header and a 10 pin input header. Due to the design of crimp connectors and flat ribbon cable, the pins are double the normal count required, so that two wires on a flat ribbon cable connect to each signal. This makes it 5 input and 8 output signals. Input: The 5 input signals can be directly wired to a DB-25 male connector using a 10 wire flat ribbon cable and a 10 pin crimp connector. You can fit a 'back shell' to save the wires breaking off. Alternatively, you can connect the DT206 board to a DT004 board using a pair of 30 pin right angle male and female connectors. (see pictures).

Output: The 8 output signals match the ISP programming header on the and boards. This can be wired up with a short 16 wire flat ribbon cable and 16 pin crimp connector at the programmer end, and an 8 pin female header at the other.
You will need to either cut off every second wire, or solder two wires to the one pin of the header. Heat shrink will help these wires from snapping off with continual use. Please note. Two signals aren't used in the cable, so it is really only 6 connections for output. Perhaps something could be done by making up an adapter with a small vero board, a DB-9 female, and an 8 pin female header. All you need then is the 16 pin flat ribbon cable terminated to a DB-9 male connector. Power: The SPI Programmer gets its power from your target board, however a link is provided to get it from a DT004 board if required.
Alternatively, you can also power the target board from a board. Software: My main reason for producing the ISP Flash Programmer, was to support the AT89S8252 when used with, so there is already a driver for it built in to this product. BascomLT is a great Basic Compiler at $49USD available from Dontronics via web download. Is the Home Page original designer Jakub Jiricek. You will find windows and DOS drivers at this URL. Parts List: 1 by DT206 PCB (both programmers on one board) 1 by 74HCT126 (E2) 2 by 1K Resistors.25 watt 2 by 5mm LEDs.
A set of 2 by 8 male header pins suitable for connecting a 16 pin crimp IDC connector and flat ribbon cable to. Suitable simple hardware to connect this cable to your target board. Optional: A set of 2 by 5 male header pins suitable for connecting a 10 pin crimp IDC connector and flat ribbon cable to.
This can then connect to a DB-25 male connector with a back shell fitted. Or alternatively, use a DT004 board as a front end. J1 Header: A set of four male pins can be fitted to the J1 header position if you choose to use the following +5V power features.
The default setting is to have the Flash Programmer get it's power from the target board. By cutting the track on the solder side of the board from pin 3 to pin 4, and using the pins and test links, you can power the programmer from a DT004 board if you wish by placing a link on pins 1 and 2. You will see that pins 2 and 3 are connected together. If you connected all pins together with two test links, your target board can be powered from the DT004 +5V supply. Current Status of the SPI Flash Programmer: This section of the board has yet to be tried and tested. As the schematic is simple, we feel there shouldn't be any real problems, however feedback is appreciated.
This section was done to fill in the blank space on the board and to provide a low cost SPI Parallel Port driven programmer. 25-May-1999 DT206 ISP Programmer INFO: Hello Don, I also noticed that with both IC's populated, it would not work. So one of the 2 chips must be removed. About ISP programming: this is really a pain. Not all LPT-ports are compatible and for some users, it will not work.
Don's design is compatible with the design I use. Best regards, Mark Alberts (Author Bascom Products) AT89C2051 Programmer: The rest of the board is a very fundamental AT89C2051 Programmer that uses a single 74HC174 chip and a bit of power supply switching logic. I have only seen one that contains less parts. That is the Blowit Programmer by my good friend Antti Lukats.
This does a blind program, however it has just been removed from the web (30-Aug-98??) as he has chosen not to support it any longer. Input: You can connect the DT206 board to a board using a pair of 30 pin right angle male and female connectors. (You will see the pictures when I get boards). This gives you the power supply front end and the DB-25 input.
Sure you can build your own, but the DT004 makes it very simple, and is re-usable for other projects. Output: A mass of pins that may be daunting when first appraised, but again, this has been done to allow many options. First, read and in particular, the part on ZIF to standard sockets. Method 1: My first recommendation is to get a good quality 40 pin machine pin socket, hopefully one of the types that has three struts in the center that can be easily removed, so that two strips of 20 pin headers can be made.
Alternatively, you may be able to get 2 strips of 20 pins. This makes it easy. Solder the two strips into the socket area marked 1-20 and 21-40. This lines up with the number 1 in the string of 1-2-3 numbers. These are at.6' centers.
Get an Aries 40 pin socket. This will push into the 2 strips you have installed. This allows you to remove the socket for other projects (even on this board) if you wish. Method 2: Solder a 20 pin Textool socket into the.3' positions marked 1-10, 11-20. Or using the methods in, go via 2 strips of 10 pin headers so that this socket can be removed for other projects as well.
What are positions 2 and 3?? By soldering socket strips into each location, it gives you 3 positions to install a 40 pin Aries socket. The first position is for the AT89C2051.
The other 2 positions can be wired with 5 jumper wires from the socket strip positions 2 or 3, to the pins on the male 30 pin header at the Simmstick bus. These connections are then selected by moving the 40 pin Aries ZIF socket from position to position. You can now have a, or AVR programmer. The two positions will allow you to configure for two different types of chips. This will cater for 8, 20 or 40 pin micros.
No need to worry about diodes or resistors for power as the DT004 has its own power. This multi-position 40 pin Aries socket idea, is one that I have kicked around for years and yet never got past the in-head design stage. If it appears to work, I may well start laying down other Simmstick programmer designs using the same technique. It's my belief that all DIP programmers should be based on 40 pin multi-pitch sockets such as the 40 pin Aries. Power: All built into the re-usable front end. The wall-wart or plug-pack can be AC or DC as the input has a diode bridge, however the input voltage needs to be high enough to produce 12 Volts at pin 1 of the Micro socket. This means an input voltage of around 14 to 18 Volts.
As an alternative, two 9 Volt batteries can be connected in series to make up an 18 Volt power supply. A small wiring harness with two battery clips and a DC connector can be made easily for this task. Software: is the software produced by Peter Averill, who also designed the circuit of the AT89C2051 Programmer. Peter teaches Electronics at the Western Melbourne Institute of TAFE in Australia. We hope to be able to include Peter's driver in in the future. BascomLT is a great Basic Compiler at $49USD available from Dontronics via web download.
