Which pic? up to date basic chip for 16f877

[Acetronics2]

Being serious ...

Why not consider the 16F887 ??? ... just intended to be the 877 successor ...

and overall much cheaper than the 877 !!!

Add to that ... OSCTUNE command to precisely trim your INTOSC ... he,he ...

It is my personal opinion that everyone should stop using the OLD 16F's completely.
If you've already designed something with them, they will be available for a long time, so keep building those products with the old stuff.

But if you liked the 16F's, and are designing something new, move up to the 16F1 (enhanced core) devices.
They are so much better than the OLD stuff.

To replace a 16F877A, use a 16F1937.

32Mhz Internal oscillator
16 Level Stack
16 channel Capacitive touch sensing module
Integrated LCD controller
5 CCP modules
5 Timers
A built in 555
All the normal stuff too ... EUSART, MSSP, Comparators, ADC etc.

Wow, thanks Darrel that chip looks exciting.

So many possibilities.

Although, even on ebay the chips are relatively expensive. The cost of the chip is more than the rest of the components in the project !

Wow, what's 1/2 million transistors worth compared to a few peripheral components? I think given the complexity of the PIC it's cheap relative to the rest of the circuit. Just my opinion though.

I'm always surprised how cheap these things are now....1/2 to 1/4 the price

Thanks all,

I've ordered both chips, 887 and 1937.

For those that thought I was being mean, I've ordered so many small amount parts recently that it was brought to my attention by my wife just how much I had spent in total ! Besides, I'm on a pensioners budget.
