How many times can I write to the Stamp

I seem to recall that I can reprogram a stamp many zillions of times.· Can anyone tell me how many?

Also, if I write data to an eprom location or serin data to the stamp, does that count as one of my reprogram events?

If I have a VB application that is constantly writting an update to the stamp at 4800 baud, am I in effect "buring up" the stamp?

Thanks All!

    Read the EEPROM datasheets for detailed specifics. It's somewhere between 100,000 and 1,000,000 times for any given location in the EEPROM.

    When you download a program to a Stamp, that counts as one time. When you write to EEPROM using the WRITE statement, that counts as one time. Changing a program's variables does not count. Those are RAM locations and do not wear out. Also, there are no limits on reading from the EEPROM.

    Writing and reading from the serial port can be done an infinite number of times. Using the "WRITE" command to send that data to the BS2 eeprom can only be done 100,000 to a million times.

    You could program the BS2 once a minute for a really really long time and not wear it out. The problem comes when people use the "WRITE" keyword to one location and do that under program control once a millisecond -- that will wear out that location of the eeprom in a week or so.
