I have a few NXP 8051 chips P89V51RD2 in 40 pin package. They cannot be programmed with Flashmagic most probably because the bootloader is corrupted. I looked at a few Universal Programmers on ebay etc. but most of them are beyond my budget and some do not support the NXP chip.


If anyone knows of a parallel programmer circuit which can be fabricated at home on a protoboard, please post the link.

In case there is no solution, I am planning to go for the one at

http://www.ebay.com/itm/USB-SP300U-Programmer-51-AVR-ATMEL-MICROCHIP-SST-STC-93-24-25-29-39-49-chips-/221072206528?pt=LH_DefaultDomain_0&hash=item3378ee2ac0

This one has a demo mode to get a feel of the software without the hardware being in place. Also the firmware can be upgraded as new chips are added.

Cheers.

.. not the most expensive options for programmers saw on taobao.com .. Search - U-EC6 ..http://s.taobao.com/search?q=U-EC6&searcy_type=item&s_from=newHeader&source=&ssid=s5-e&search=y&initiative_id=itemz_20130829

Found this Blog which has some really interesting details to restore the Bootloader of the NXp's. Hope it helps you.

Had seen that blog.The programmer recommended costs around $290.  That led me to search for a low cost solution but could not get a circuit of a parallel programmer.
Best regards.

Sunrom is manufacturing a dedicated programmer with zif socket for Just one chip 89V51RD2 cost 1500/- Indian Rupees per PC.

Guess a lot chip may be restored with this. Going through the details on their website i nowhere found the word "parellel programmer". You may communicate with them for more details about the same. I dont intend to advertise for them here.

Looks like a device which uses the bootloader.
For reprogramming the bootloader a device programmer is required.
Attached a file about Philips ISP/IAP which might be helpful.

I have here a GALEP4-programmer, but im afraid im too far away.

Simple, easy to use and inexpensive considered.

In device manual:
The 8051prog™ programmer is a great tool used for programming 8051 microcontrollers from Atmel®. As a low-consumption device,
it is ideal to be used with notebooks. It’s unique design and simplicity make it a very popular tool among beginners and professional
users alike. The 8051prog programmer communicates to the microcontroller through a USB cable which is also used for powering
the programmer. In order to use this programmer, it is necessary to have the 8051Flash program and the appropriate driver, provided
on the product CD, installed on your PC. After that, you can use the 8051prog programmer and a hex code generated in any 8051
compiler to load the program into an 8051 microcontroller.
The 8051prog programmer is built into all Mikroelektronika’s 8051 development systems. The same programmer is also available as a
stand-alone device used for programming 8051 microcontrollers built into (soldered on) the target device.

That one uses the serial port and depends on the bootloader for programming.It will work with flashmagic provided the bootloader is not corrupted.

Hello,

The Mikroelectronica programmer uses Atmels ISP for programming.
The older Atmel 89C51 (without ISP) are not listed in the device list.
I am in doubt that this is working with a Philips device.

The cheapest solution if You cannot access a device programmer which knows the
special features of the Philips device that two blocks of flash are mapped to 0-1FFFH
would be to get a fresh P89V51RD2.


Best Regards
--
P.S.: If You have plenty of time, You should read application note 285 from Atmel.
(http://www.datsi.fi.upm.es/docencia/Micro_C/atmel/doc0285.pdf)
It contains the schematics for a real device programmer, which was necessary for the older 80C51/52.
This one should be able to let You reprogram the P89V51RD2. But i think it cannot write a new bootloader.

Best Luck

Mention of "parallel programming" is there in the datasheet of P89V51RD2 under section 7.2.1

Yes i know well about the mention in the datasheet. I was refering that SUNROM nowwhere mentioned their programmer is a "parellel parogrammer" . Hope my words are clear now.

Certainly Pushycat.

I feel the SUNROM device is not worth the price for its ability to program just a single chip.
I finally ordered the SP300U programmer. The price is reasonably low and it can be upgraded to include future ICs.Will post about my restoration of the chips as soon as I get it.

Cheers.

I think you took a good desicision of going for SP300U. Please do post the developments regarding restoring the bootloaders when u r done. By the way just curious about where u ordered the SP300U from? Is it from a Chineese vendor or Indian? Cheers

Hi Pushycat,
I am happy to report that I managed to restore the bootloader of all the faulty P89V51RD2 chips by using the SP300U. Really a great piece of programmer for the price!! The software interface is very user friendly too !
Here is the link from where I got it
http://www.ebay.com/itm/221072206528?ru=http%3A%2F%2Fwww.ebay.com%2Fsch%2Fi.html%3F_sacat%3D0%26_nkw%3D221072206528%26_rdc%3D1
I recommend you grab one . You will not repent the purchase.

I have personally built SP200 with the  DIY pack what is available on the net. Its working fine with 89S52 as firmware chip. Now trying to go for an enhanced version..Thanks for the good news..Best of luck
