nenaprogramovaná čipová karta Funcard 7 (AT90S8515A + 2 x 24LC1024)

This FUN7 card I simply had to put into an entirely new section from the other FunCards when this card is no simple case of pull out one EEPROM size and stick in another. Not that you can do this hot swapping on wafer card mind you but you should know what I mean from the above FunCards.
The reason why this card is different from the other FunCards is that to move from the FUN6 to the FUN7 card you would expect to upgrade the 24LC1024 EEPROM to the 24LC2048 EEPROM. Bingo! Your new FUN7 card is born when you can slot it in with all the other cards while you get busy on the 24LC4096 EEPROM for the FUN8 card.
Unfortunately the flaw with this ever doubling the EEPR0M size is that there is no 24LC2048 EEPROM. Damn! Now there will be no FUN7 card you may think. Then again if you look closely at the above technical details you will see that the AT90S8515A has a small surprise in store.
This surprise I can now reveal is that this FUN7 card comes with two whole 24LC1024 EEPROMs wired in. That is all of 262,144 bytes of combined storage, or 256 KB should you wish to round up to something more common. Modern flash devices can certainly do better but this is a damned lot of storage for the tiny size that a wafer card has available.
If you remember the former PCB based Quadra cards then this FunCard seems very much like the FunQuadraCard. Packing all this equipment into such a tiny space explains why this FUN7 card will always cost quite a lot more than the other FunCards.
Anyway should you need a huge amount of data storage on a wafer card then there is unlikely to ever be a card on this very cards page that can hold as much. There will never be a FUN8 card either now that all the suitable pins on this microcontroller have been used to support the largest sized EEPROMs.
One thing I should add is that some people like to ask me how these FUN6 and FUN7 cards can have 24LC1024 EEPROMs when Microchip does not yet make a 24LC1024 EEPROM? The 24LC1024 happens to be a Microchip model code where Microchip only do the 24LC512.
The answer to this question is that every card on this Card's page will actually contain a slightly different EEPROM model to that stated where all smartcard suppliers like myself stick to a standard EEPROM format, namely 24x1024, 24C1024 or 24LC1024, to indicate compatibility with other cards on the market. In this more extreme example FunCards are actually made using Atmel EEPROMs for compatibility reasons. Atmel microcontroller matched to an Atmel EEPROM.
So there is your answer to why I and other supplier's mention the 24LC1024. You can also begin to see why some problem Funcards have been known to hit the market with a microcontroller and EEPROM timing issue, only from other suppliers I should state, due to manufacturer's making use of real Microchip EEPROMs due to cost savings.
You can also be certain that all the common FunCard supporting programmers around will support this FUN7 card. I should also mention that you should be able to use all the common FunCard firmware in this card when such firmware will simply ignore the second EEPROM.
