Hi people,

Here in France, some I²C peripherals are quit expensive. For example, a PCF8574 is about 6 euros (6$) for one part.

Does it sounds good to you to replace this chip by a 8051 derivative which may be more cost effective. Moreover, it could be possible to add some more cleaver functions inside...

Do you see any industrialization issue in this method ?
If not, I don't see how Philips could maintain these I/O chips if it's cheaper to use a micro ?

Waiting for your comments.
Regards
Stephane
