Which type of PIC do I need for the 3x3x3 LED CUBE?

I was building a 3x3x3 LED Cube from an Project (http://bit.ly/zTINhW)and one of the part needed was an PIC16F690 microcontroller,so I visited the manufacturer website (Microchip) and found the Product but with different annotations (I don't know what they mean) at the end.

SO COULD SOMEONE PLZ TELL ME:

Which type of PIC16F690 do I need:

PIC16F690-E/P

OR

PIC16F690-I/P

OR ELSE SEE: http://bit.ly/zWPoZCPLEASE

COULD YOU TELL ME WHICH ONE OF THESE ON SITE LINK ?

THANKS IN ADVANCE

Look at the Product Identification System section on page 305 of the datasheet. That shows you what the characters after the type number mean.
P is the PDIB (dual in line) package which I assume is what you want.
The I or E is the working temperature range.  E is the extended range (-40 to +125) but you'll be fine with the Industrial version (-40 to +85).  It'll be cheaper too.

One you can program - see www.picaxe.co.uk

I can program the PIC as well with the MPLAB IDE, any way Microchip's microcontrollers are cheaper than Picaxe's.

But thanks for recommending.
In that case all you need is a PIC with sufficient I/O for the task.

Are you charlyplexing or using some kind of output buffer?

Beyond that the task is mainly building and writing software to output the patterns.

I keep meaning to build a cube, perhaps a little larger and drive it from a paper tape reader so I can punch patterns on the tape.
