89C51 - 89V51 PROGRAMMING PROBLEMS

[RFrutos]

Hello, I've been using the P89C51RD2 and AT89C51RD2 for years without
any problem in several desings. But it seems that these MU's will be
discontinued and substituted by their Pbfree parts, P89V51RD2 and
AT89CRD2-UV respectively.

When I've received the first pbfree prototypes I've had problems to
programm the chips. Not the phillps
and neither the atmel one can be programmed any more.
Does anybody knows something about that????

I've not tried them, but have you got the latest Flash Magic? That says
it supports the 89V versions.

Hi ,

I have the Philips P89V51 programming well from both serial programming via
the P89V51 UART and Parallel programmer

Serial programming P89V51 download latest "Flashmagic software" - Also has
a good discussion forum for programming these devices.
http://www.esacademy.com/software/flashmagic/

P89V51 Parallel - There are 2 fash blocks
Block 0 has the code
Block 1 has bootloader programming code.
==> You MUST NOT erase Block1 unless you want to write your own boot
loader.

On power-up the P89V51 loads Block 1 takes over the 1st 8k of the code space
and starts excuting the boot loader....
If block 1 is erased it cant switch back to the normal code area (block 0).

If you accidently erase the boot code in block 1 - you can reload it by
parallel programmer - code is on the philips
P89V51 PIP page (product info page)


A good fourm in on www.8052.com


ATMEL - sorry no exp.

What makes you think they are to be discontinued?

Component manufacturers everywhere are replacing parts with their PB free
versions.

This is simply not true as far as the Philips parts are concerned. The
P89C51RD2 been lead free for over six months and is not being replaced by
anything. The P89V51RD2 is a different part altogether.
