heres the datasheet:

and botom picture is a snapshot from the datasheet (2nd one)

PIC16C57 is not the same family as PIC16F5x :!:

I have them, by the 100's and Nigel right about the paralel programming !

:arrow:

The PIC16C5X Series can be programmed by applying
the 12-bit wide data word to the 12 available I/O pins
while the address is generated by the on-chip Program
Counter. The MCLR/VPP pin provides the programming
supply voltage (VPP). Programming/verify chip enable
is controlled by the T0CKI pin while the OSC1 pin controls
the Program Counter.

No it's not, the 16F57 is the modern replacement for the 16C57.

If they were serially programmable I'd use them myself 8)

The Pic16C57 is not serially programmable. It's an old generation of Pics MCUs. It has no Timers, only One interrupt source, and is OTP. The very limited resources on this pic makes it quazi-impossible to do usefull developments on it using a compiler. Most of the compilers on the market (Basic, C, Pascal ....) do not support this chip and some times PARTIALLY supports it. The problem is that this chip is a 12 bit core, its like the 12c50x family, it's not a 14bits core (like the 16c84). The only way to do something usefull with this mcu is to use asm.

Hi, are those stollen :lol: ?

Oh then there useles to me!

No! :lol:

BTW, I've had a count (after dusting the tubes), I've got 273 of them!, 17 tubes of 15, and 2 tubes of 9.

This would make for a pretty large parcel, so I'm far more interested in someone collecting them, rather than having to parcel them up.

funny...

One post about how bad our throw away society has become...

And here another crushing perfectly working parts 'cause they are a bit older.

It's that i dont have a parallel programmer eighter or i defenately would buy some of 'em. I'm sure i can find many uses for them.

bluex_scf · Apr 18, 2005

Hey .. Nigel, I would like to get them. I have developped some specialised circuits Firmware (with mpasm) so far for the 16C57RC and I would like to use it again for the XT Version. So do not throw them ... I will pay for postage.

csaba911 · Apr 18, 2005

WOW, if is only for the postage then send me some to ~1-5 tube!
I have programmer for them and did use many of this monsters.
Currently I have tons of 16c54 but the few #io pins limit the usages.

PIC16F876A and PIC16F877A

We have an overstock in our inventory of PIC16F877A and PIC16F876A, pm me if you are interested 10 and above quantities.

Does anyone have any CHEAP 16F84s left?

We are building a flight sim for an Air Cadet Unit (also registered charity) and need between 15 and 30 16F84s....

Is anyone able to help?

Many thanks

and how much wud that cost me? i am a student and interested in buying for a project!

This post is a year old.

Since it doesn't look like he's posted at all on the forum in a year, something tells me you're going to wait a long time on an answer to this.

It's an old thread but I couldn't help myself. The BASIC Stamps use the 16C57

Like you said, old thread, but what point are you tring to make? - the BASIC STAMP is an INTERPRETER, it's actually programmed in assembler - the internal assembler code reads tokenised BASIC from an external EEPROM.

blueroomelectronics · Jul 27, 2007

The point was; even with a simple and by todays standards limited 12bit PIC it is possible to write some very sophitcated code ie the stamp P-code interpreter. Parallax made millions on with that chunk of code.
