P89C51RD2HBA

[francesco_fonta]

I developed a simple 8051 based development board and I want to present it in a local electronics fair in Italy. I called it "Arduone UNO" with the idea to overcome the ubiquitous Arduino.  I used a P89C51RD2HBA as microcontroller but it works only with Philips marked devices, whenever I use an NXP device I have always the same problem, it cannot comunicate with the PC using flash magic and isp connection. Now, since the fair is very close (30 31 of this month) and I wanted to sell the NXP devices as well, do you have any suggestion on how to make the NXP marked devices work? There is no way to read the signature and no way to reload the booloader. Is it due to a seller that has only defective NXP devices or is there any way to overcome the problem? I read in some cases a parallel programmer should be used to unlock this device. Please let me know. I would apreciate an help. Thank you.

If you need a recommendation please let me know

Yes please, I need a similar PLCC44 microcontroller for the next versions of my development board. PLCC package is needed because the board is for hobbysts. Thank you

This device is still available

but I am not sure if this can work for your application

[francesco_fonta]

If it is One Time Programmable of course not. I believe NXP shouldn't underestimate the marketing potential of hobbyists, still producing some PDIP or PLCC micocontroller for them. Atmel is doing fine with a relaively poor microcontroller with Arduino. If you get to know a good alternative please let me know, I will design a new board around it. Thank you for your help.

Yes please, could you suggest me anothe PLCC44 device to replace that one?

I am still purchasing that device but I am aware that some day it will be no longer

available. Thank you. Francesco
