Programming OTP vs. EPROM issue

[oscar]

Hi all,

I have been doing my development for a PIC16C771 with a EPROM-UV erasable part until today that I had to actually program a OTP version of the PIC16C771. I have basically trashed two OTP PIC16C771's via ICSP. It programs it and at the end it gives me an error that looks as follows (excerpt from error file):

Device Type: 16C771
Program Memory Errors
Address Good Bad
0001: 008A 3FFF
0002: 29FD 3FFF

000A: 0084 3FFF

001C: 0064 3FFF
001D: 0B80 3FFF
001E: 280E 3FFF
001F: 3400 3FFF
0020: 1705 3FFF
Any additional errors are not displayed.
Configuration Bits Errors
Configuration Setting Expected Received
Oscillator INTRC I/O ER CLKOUT
Power Up Timer On Off
Brown Out Voltage 4.2V 2.5V
Master Clear Enable Internal External


It says that the configuration bits and the actual program memory were programmed incorrectly. With the UV erasable part I never had these problems.... I think that my ICSP connector from my PICSTART PLUS may not be carrying all of the signals. Currently I have Vdd, Vss, Vpp, RB6 & RB7 connected from the programmer to the PCB. I have only one more 'C771 OTP part left and I don't want to program it again and have to trash it because I'm doing it wrong. Has anyone encountered this problem????

Thanks,
O.

Don't throw those parts away yet. From the data, it looks like the part is not programmed at all. When you program the EPROM version, is it installed in the exact setup that you are programming the OTP?

It sounds like you have been doing your development with a UV part, programming it with the PicStart+, then putting it in you circuit. Now your tryingto use in-circuit serial programming to program the OTP device.

First, you can program the UV part using the serial method just as you can the OTP. Try that before you waste your last OTP part. Second, what is your clock configuration? I remember reading somewhere that if an external RC clock was being used, it needed to be disabled (i.e. jumper) during programming.


Also, check out the programming spec on the part. It has some caveats about Vpp, Vdd,and MCLR that you should read if you have not already.

Well, let me clarify things a bit. I have been doing my development with a UV part (Internal oscillator INTRC) on a protoboard. I used to program the UV part on the PICSTART plus and just plugged it into the protoboard and life was dandy.

Now I have my circuit layed out on a PCB with a OTP part so I just brought out the vital lines indicated in the icsp programming spec, namely Vdd, Vss, Vpp, RB6(sclk) & RB7(sda).


I will try to attach my UV DIP part to the PCB SOIC pads and try to program it like that. I will let you know if I succeeded.
Thanks,
O

No, the EPROM part was programmed on the PICSTART PLUS programmer then I plugged it into my protoboard. Now I have my OTP part soldered (which I regret) into a PCB... I think you might be right.... it looks like all the locations are at 3FFF which means non-programmed.....
Do you have any advise?
Thanks,

Refer to the Microchip website for an App note regarding in circuit programming. Make sure that you have implemented it correctly. I believe all power pins must be powered. Special care must be taken in regards to the MCLR pin. This will have higher voltage the the Vdd pins. Make sure that your circuit is not dragging down the voltage.

PS: I like using machine pin sockets for the micros :)

Mark

Yes, I will double-check everything well.
I like machine pin sockets too except that my OTP micro on the PCB is a 20-pin SOIC.... couldn't fit a 20-pin DIP there.
Thanks.
