'[PIC]: Cheapest PIC ??'
2001\04\24@084055 by Roman Black

Hi, someone mentioned the cheapest PIC chip
here a few weeks back. I need to choose a
chip that's very cost conscious, I need
11 in/out pins, and minimum 512 words program
memory. 1k word would be better.
12-core is fine with no interrupts, as is
4MHz RC osc. No frills needed!

Maybe a 16C54 ??

Any suggestions? Pref something that is very
cheap AND easy to source, I hate 6 week lead
times with every order. :o)
Thanks!
-Roman

Roman:

Look at the PIC16C505. Has an internal RC osc.
12 IO pins and is ISCP friendly. Also has 1K of
memory with 72 bytes of RAM. You can get them
from digikey for:

Quantity                Unit Price (US Dollars)
1                       2.05
25                      1.26
100                     1.22
1000                    1.19

Hope this helps!!

Hi Roman
Without checking the specs, how about the 16c505?
It's like a 12cxxx with extra I/O.

16C505 will be cheaper, and also has the internal RC osc

Look at the 16C505 - internal RC saves a couple of pins.

That was the 16C505. But you have to buy a VERY large amount.
Probably around 100K.

Thanks everyone! So the 16C505 is the cheapest
PIC with more than 8 pins huh. Since Microchips
lame website doesn't have prices does anyone
know the trade (Arrow?) price for 500 quantity
of the 16C505?? Steve mentioned around $1.20
from Digikey. We don't have digikey here.

That would be the 12C508A.  It is an 8 pin part and has a maximum of 6 I/O
lines.  Also, it doesn't get down to $.50 except for LARGE quantities.  Still,
it's the cheapest PIC there is, even if it might cost $.75 in medium
quantities.  I've used this PIC as a watchdog, a morse code tone generator,
a stepper motor controller, and a brushless DC motor controller.

Roman,

Arrow lists all prices on their website this way. It's annoying as hell, I
think. What you get is the single piece price -- if you want the *real* volume
pricing you must contact them directly.

Sure you do.
They are one of the better online component sources for we upside-
down folks. They have better freight rates than many US suppliers.

They are like Farnell in that it pays to check their prices. Many
times they are expensive but on some items they are better than
the local folks including the freight overhead. In quantities of say 20-
500, Farnell are the best priced source of all the PICs I use. Well,
they were - I haven't checked all of them in the new catalogue.
They're ex-stock (or a few days) as well.

Farnell 100 up prices (US$)
12C508  $1.16
16C505  $1.77

Thanks Matt. Well that is good news, normally
we find that their 500 unit price is a good 30%
to 40% off the single price, so if they quote
$1.48 for singles that might be around $1.10
for quantity. That would be cheaper than the
Digikey price Steve mentioned. :o)

Those prices I quoted were Farnell prices converted to US$ for
comparison. A quick search shows the 12C508 listed as $0.94 at
Digikey (qty 100) and $0.87 at Newark (with a note that restrictions
apply). Digikey have the 16C505 at $1.19 (qty 1k) and Future at
$1.06. All prices in US$.

Thanks Peter, if anyone is interested I contacted
Arrow (Australia) today and the PIC 16C505 4MHz
is $1.91 AU ($0.96 US) in quantities of 500.

This price is much better than the Digikey or Farnell
prices, for anyone that might need a current price
like I did yesterday. :o)

And the 16C54C is the cheapest PIC with more than
8 legs. It's actually a few cents cheaper than the
16C505, but has less rom and much less ram, and as
it needs external RC that adds a few cents and
board costs.

Thanks to everyone who helped me with prices and
suggestions!
