What does this chip actually do?

Its labeled MACH210-15JC-18JI
I've looked over the data sheet, and it says:
44 Pins
64 Macrocells
Peripheral Component Interconnect (PCI) compliant
32 Outputs
64 Flip-flops; 2 clock choices
4 “PAL22V16” blocks with buried macrocells

So, it holds data bits with flip flops? In the specs it says D or T type flip flop.
Its programmable, but what does it mean by that, how would you "program it" it has 44 pins, and some I/O.

What do you think the applications of it are? I have the pinout, but that doesn't really do any good if I can't figure out how to "program it"...

It can run at 133MHz tops, but if this was memory there would need to be a section that says when to read/write on rising or falling edge of said clock. It doesn't say that.


EDIT:
So.. what does High-Density EE CMOS Programmable Logic mean?


Sorry for the questions lately, just trying to figure stuff out

This is called a Glue Chip for logic.

When an engineer has a complex electrical system [A] and wants to
combine with a second electronic system [C]
he can use perhaps 30 discreet ICs to combine the two systems.

But if the engineer is familiar with PAL ( Programmable-Array-Logic )
He can design this 44 pin chip to perform the necessary  logic of the
30 discreet ICsin the 44 pin IC.
To Glue the systems together  [A] => [Glue] => [C].

If in testing phase  there is a desired change to be made to the
PAL device and since it  is Electrically Erasable and then Reprogrammable.. The device

This device can build processor elements, or counters with special
outputs, or very complex gates by simple design or library's..

A..

Its a whole bunch of logic ICs inside the chip whose actual function you can program into whatever you need, within the limits of the number of macrocells. You program it with a language called VHDL, VLSI hardware description language.

Well thanks for the information... I'm not at the level to use these I guess. I recently got 600 of these and a bunch of smaller and larger versions that fill up a drawer -.-

Thanks for the best answer.

I'm a Pak-Rat too.....
Here Iam sitting on tubes and tubes of earlier 18 pin PIC micro processors.

These were interesting in that they were EE ( Electrically Erasable ) 4.5V..to..5.5V tolerant devices  with  the following very usable excellent Quirk. 

Normally Re-Programming meant the chip was first erased and then the program was "burned" into the chip.
But when the erasing feature was deactivated after the first re-program and the same program was "burned" into the chip another 15..to..22 times that PIC would Run and Function DOWN to 2.2VDC !!!!..

Then and there Now we could do simple two cell battery portable products with a low priced non-military micro-processor :-)
