Richard, this is the exTemic group, not the "original Atmel".

The P89V51Rx2 series are NXP chips with the same/better features than the Atmel stuff. and the errata is up to date



No, they are not. They are apparently SST chips, rebranded. Not that they are bad chips.

And they don't have enough RAM for the OP's needs (only 768 bytes, but Philips/NXP calls it 1k (adding the internal 256B to it)).
