What do I have?

[cdngunner]

And can any of this be used with a pic and what applications would they be used for.

The only useful one I think would be the RAM one.

i have

1. CYC7C4261 16Kx9 Deep sync FIFO
http://www.cypress.com/?docID=24690

2 CY7C006-25JC 32K/16K x 8, 16K x 9 Dual-Port Static RAM
http://pdf1.alldatasheet.com/datasheet-pdf/view/165932/CYPRESS/CY7C006-25JC.html

3. DAC8408 8 bit multiplyimg cmos
http://pdf1.alldatasheet.com/datasheet-pdf/view/48954/AD/DAC8408FP.html

I also have a couple of Altera FLEX chips

EPF8282ALC84-2
EPM7128SLC84-6

dont even want to get into learning how to program them

Not sure what to say because the description (that you have stated) IS what you have.

1. FIFO. First in first out.
You put data in and then take it out in the same order it went in.
You can shove data in one end at high speed and then take it out the other end (in the original order) at your leisure. eg send data to a printer quickly while the printer processes it slowly. It can take data which is 9-bits wide (8-bit data plus parity bit) up to 16k before it's full.

2. Dual-Port Static RAM
It's well... Dual-Port Static RAM
That's static RAM which has two ports. This allows two devices to write to the same RAM location at the same time. Very useful for 'things' which need to share the same data. eg a micro and a video chip.

3. DAC8408 8 bit multiplyimg cmos
A digital to analogue converter with 8 channels. The 'multiplying' bit is that the output is the digital input multiplied by the reference voltage. Very useful if you need to multiply a digital number by an analogue voltage.

Don't know the others but I've used all of the above frequently with parallel port (full address and 8-bit data) micros but never with a PICAXE.

3. DAC8408 8 bit multiplyimg cmos

Is a 4 channel DAC (ie 4 DACs in one chip) each with 8 bit resolution.

It takes an 8-bit parallel digital/binary input as data and needs 4 extra signals for full control (excluding reference voltages) and thus needs 12 IO from a PICAXE unless you are going to try and drive it via an i2c IO extender chip or shift register - which will slow down control.
The DAC's are using R-2R resistor ladder networks for the conversion.

Thanks for the correction westy.
The DAC8408 is indeed four channel and not eight.
A great chip for use with micros having an 8-bit data bus but not the best choice for use with a PICAXE for the reasons pointed out.
