1. Major specification:
256-byte EEPROM architecture;
32-byte memory architecture;
3-byte user cipher; Cipher error counter: 3 times;
Range of temperature: 0º C~70º C;
Repeated record: At least 100, 000 times;
Data duration: At least 10 years.
2. Memory layouts:
3. Secrecy characteristics:
Writing of every byte in the writing protection area (the first 32 bytes) can be protected independently. Following writing protection, the content cannot be recorded (i. e. Solidified data).
All data can be read before cipher is verified right. If necessary, data can be ciphered properly.
Writing or recording can be done after cipher is verified right.
The 3-byte user cipher can be recorded after it is verified right. It will be valid until the card is powered off.
The initial value of cipher error counter is 3. It will decrease 1 for every time the cipher is verified wrong. If counter value is 0, the card will be locked automatically while the data can only be read out and any recording cannot be done nor cipher verified. On the other hand, if counter value is not 0 and if only the cipher is verified right in one time, the initial value can be regained.
Byte addresses 21~26 are user codes. Our company can set up a unique global code here for major customer for user to issue and use uniformly (all cards cannot be recorded upon delivery).
Byte addresses 0~5 and 6~7 have been written well by the manufacturer and are not recordable.
4. Note:
Cipher area is addressed separately beyond 0~256 bytes.
