A, main index:

L 256 bytes EEPROM

L 32 protection of EEPROM, before a 32 bytes written protection

L card always can read; Write CARDS must be through the password calibration.

L 3 bytes user password, password error count: 3 times.

L: 0 ℃ temperature range ℃ ~ 70

L CaXie at least 100,000 times

L at least 10 years data storage life

Second, confidential features:

1. The password calibration before all data are correctly, can be read, if necessary, can proper for data encryption. Password calibration is correct writeable or modify data.

 

2. Three bytes of user password, calibration through electrical, to card after has been effective. Calibration through password itself can change after.

Note: Ed, not MiMaOu another address 0 ~ 256 bytes inside.

 

3. The password error counter the initial value for binary 0111, password calibration error 1 times then lose a 1. If the counter value is 0, the card can only be automatic locked, data, do not read again, so it can't again password check for updates. When the counter is not correct, namely password calibration flinging recovered to the initial value.

 

4. Write reserve (former 32 bytes) of each byte can write protect separately, write protected, content after no more change (namely curing data).

 

5. Bytes for users 0x15 ~ 0x1A address code, SIEMENS company provides exclusively in the major users, the only global code, so that a user use (all the CARDS issued unity after they leave not revise again).

 

6. Bytes address 0 ~ 7 before they leave the factory, already by manufacturers to write good cannot be changed.
