Addressable serial bus Chips (eg: 1-Wire, I2C)

[Brook Stevens]

Maxim has 1-Wire chips like the DS2408 which is an 8 i/o addressable chip
each with a unique 64 bit ID.

Philips has their I2C/SMBus chips. For example, the PCA9539 is a 16 i/o chip
with 2 bit ID (so only 4 devices on one I2C line).

Are there other addressable serial busses (ie: any fieldbus like Modbus,
etc.) that have all-in-one, easy-to-use, chips???

The SN74LV8153 chip below might be of interest. I got some free
samples from TI (use the samples link), but haven't been
successful in controling the chips from the PC serial port.
