'PIC - what does it mean?'

Dear All,

I'm sure this question has been asked by a great deal of people...

I've just started writing my thesis for the project and it would be awful
handy to know what 'PIC' actually meant. Is it an acronym? What does it
mean? etc. etc.

Can anybody (i.e. Andy Warren or Microchip) help?

Thanks.

J.W.

Peripheral (sp) Interface Controller.

Don't remember where I read it.

    Although I am not a PIC originator...   I have heard that PIC is from
    "Programmable Interface Controller"  in that the architecture was
    first envisioned as a programmable interface for larger (mainframe)
    computers.

General Instruments (the originator of the PIC) called it a "Perpheral
Interface Controller" as it was intended to offload peripheral management
from the main processor.

If I remember correctly, PICs in those days were NMOS and masked ROM only.
Microchip (which I believe was a GI spin-off) has taken it a long way (due
in part to Motorola supply shortages. Motorola OWNS the embedded world, or
at least USED to).

    Brian,

    I'm sorry to contradict you, but I've always heard it "Peripheral
    Interface Controller"

I propose that it should mean:

"PIC Integrated Circuit" since everyone (present) knows what a PIC is.

It's a *recursive* acronym, see.

I believe the fist time I saw a PIC (if it was even called that) used was
to replace the Intel 8048 microprocessor in a Mouse Systems Mouse. I
remember the circuit board was drilled to take either the 8048 or the GI
part. (We were ripping the micros out of the mice and running the optical
encoders straight into our Amiga 1000S, but that is another story)

That's one meaning, but not the appropriate one in this context I think.

I've always understood it to mean peripheral interface controller

however, if you say pic to most people they associate it with the 8259A -
this is a programmable interrupt controller and is part of the PC
architecture

hence the possibility of confusion

Peripheral Interrupt Controller in the Intel world.

Peripheral Interface Controller in the Microchip world.

Dear All,

I'm sure this question has been asked by a great deal of people...

I've just started writing my thesis for the project and it would be
awful
handy to know what 'PIC' actually meant. Is it an acronym? What does it

It couldn't have been in the PIC FAQ, could it?   :)
