I could only get the first one to load. It's flash memory. You can load it with a program but you'll still have to have a processor to go with it to make it do anything. Unless I'm mistaken all it does is remember what you tell it.

"Atmel" are a major chip-maker, they make several kinds of processor, memory, CAN bus interfaces, MP3 player chips etc etc. In processors, they make AVR, ARM and 8052 !

It would, but you'll have to work out how to program the memory.

so a 8052 will work for this? im sure the datasheet will tell me programming. and can i use the flash memory to expand the memory?

Nope, same thing. Its just memory. You need a controller and a processor and other things to make it do anything.

+....about 10. Both of these are memory chips, not processors. The atmega costs less than $5

Sometimes you have to resort to paying by regular mail.

I've done this once in  a while.  you have to find out what their mailing address is and how much the bill is and then buy a mail order and send it to them

A little slower, but it still works great.
