Have you looked at the 8051 derivatives available from Philips (used to be
called Signetics in USA).

the 87C751 is a 24 pin device with:

   built in IIC bus (a serial bus for a wide range of peripheral chip, 
   and the controller code is freely available)

   19 I/O lines
   2K Eprom
   64 Byte ram
   1 16 bit timer
   24 pin chip only 0.3 inch wide (skinny dip)

I rang up the local agents about two days ago and found that this
chip is NZ$17.00 (probably about US$7) for a one-time-programmed
version and about NZ$70 for an Eprom version.

They also have other versions with more of all the above, plus two
with ADC on board, one five channel 8bit, one 5 channel 16 bit.

They also have a IIC demo board which has all sorts of peripheral
chips on it ... for about NZ$190.

PS I have no connection with Philips - I just think these are a
rather nice range of devices.


Cheers
Giovanni
