Aug 31 , 2020
The Atmel 24C64 IC Chip Card.
The 24C64 IC card is a kind of contact chip card, which belongs to memory chip card. Currently the main widely used for equipment control, data storage, etc., Such as driving trainee card, beauty equipment control card, door lock control card and so on. The 24C64 is one of the first memory chips produced by Atmel. There are also have one FM24C64 chip by Fudan Company in China, it is fully compatible with Atmel 24C64. And cheaper than original Atmel24C64 chip cards as well. Related 24C64 contact memory IC card In the following :

A series of memory card models produced by ATMEL:
ATMEL24C01/ATMEL24C02/ATMEL24C04/ATMEL24C08/ATMEL24C16/ATMEL24C32/ATMEL24C64 ATMEL memory card, is a kind of EEPROM card without encryption function, AT24C is the serial number, the digital part is K-bit capacity, respectively 1K, 2K, 4K, 8k, 16K, 32K, 64K. Its use method is exactly the same as that of EPROM, its storage structure is simple, and it only has two operation functions: read and write. It is mainly used to store some data that does not require high confidentiality.
