pulse counter

[david@amberjacksolutions.]

Hello fellows
I'm looking for a IC capable of counting pulses... Ideally with an I2C/SPI interface... Any suggestions?
Cheers

It is called a PIC uController. It has everything you need to count pulses from an external source, store them indefinitely, and then output them using either I2C or SPI (or a hundred other ways). There are 8pin DIP versions of PICs that could do this that cost ~$1

Which of the PIC familly would you suggest?
As I need to count from up to 8 different pulse generators, is there any ucontroler capable of counting from more than 1 source at a time?

As your requirements are for incredibly slow pulses any with enough pins would be fine - something like a 16F88 or similar (18 pin) - there are loads of suitable devices.
