PC programable IC?

[Michel]

Is there a simple logic programmable IC which I could program simply
by connecting it to a PC (ser, par, usb,...) Maybe even one which has
some kind of CPU and clock insite? So I don't need to spend much money
on a programing interface.

Look no feather than : http://www.latticesemi.com/
For USB the best one is : http://www.cypress.com/

What kind of programmable chip? There are various microcontrollers
that can be programmed with almost no hardware. I have a bootloader
for the Microchip 18F series that connects to the serial port of a PC
using one transistor, three resistors and a diode. It does not use any
I/O pin of the chip.

Motorola 68HC908 JK/JL series definitely program from a PC serial
port. See pg 9 of the .PDF

I've used this for several years. Its about $25 for parts. Processors
available from Digi-Key starting around $3. Data from Motorola.

Most programmable devices can be programmed by a PC to one extent or
another. What sort of IC do you want, and how complex a programmer are
you willing to build or buy?

Look at devices from Lattice. http://www.latticesemi.com. For USB, look at
Cypress (www.cypress.com).
