1. 1024-byte encrypted card, there are read data, write data, protect data and password operation


2. 1024 × 8-bit EEPROM


3. Non-recoverable write protection


4. 1024 bits of protection bits


5. Two-byte user password.


6. All data can only be read and not rewritten before the password is verified correctly.


7. Data can be changed after the password is verified correctly, including the password


8. Error counter, the initial value of 8, password check error 1, it will be reduced by 1, if the counter value is 0, the card automatically locked, the data can only be read out, can not be changed and can not be password check; if not zero, there is a password check correct, can be restored to the initial value of 8 each byte of the data area can be individually write-protected, write-protected, the content can not be changed (that is, solid data)


24C series chip parameters.


1.24C is the series number, the digital part is K-bit capacity, respectively 1K, 2K, 4K, 8K, 16K, 64K


2. Operating frequency is lMHz (5V), lMHz (2.7V), 400KHz (1.8V)


3. Operating voltage is 5V to l0%, as low as 1.8V on request


4. Current read maximum of lmA, write maximum of 3mA write /


5. Erase times for l00 million times


6. Data retention lO0 years


7. The working temperature is O-70 ℃, according to the requirements can exceed the specified working temperature


8. Mainly used to store some confidentiality requirements are not high data, such as for data storage, telephone cards and campus cards and other fields
