One, the main index
Low block of 1024 bytes EEPROM
Low of 1024 bytes written reserve curing (data)
2 bytes of password, error count eight times
Scope: low temperature - 35 ℃ ~ 80 ℃
When at least 100000 times to wipe cycle
Low for at least 10 years data storage life
Second, the functional description
1, 4428 capacity of 1 kbytes, address space from 0 to 1023.
2, all the data in addition to the password, all can be read in any case, after checking the correct password can be read.
3, all data including the password itself can be written or change after checking the correct password.
4, all the data can be write protected, according to the byte write protect data after curing, cannot be changed under any circumstances.
5, there is a password error counter.The address is 1021.The initial value of 8, check the wrong password, minus 1.If the counter value is 0,
The whole card data is locked, only can read, do not write or change and unable to continue to check the password;If not 0, the need to have a check
Correct, the counter will revert to the initial value.
6, password length is 2 bytes, the address is 1022, 1023.A total of 216 combinations, check the correct password before, read the two addresses
The result is "00", also can't write and change;After check the correct password can read password, also can change the password, the password will have been effective
Card off electricity.
7, the only code.Address is 21 ~ 26 card user code, the code is the only global user code, maximum limit to ensure that the user
Interests, this code after curing write will not change.
8, address 0 ~ 7 and 21 ~ 26 before delivery has been solidified by manufacturer, may be changed.
