Storage card is a kind of contact mode card. There is a chip-trough on one side of the card. The capacity of the chips ranges between 1kbit and 64kbit. we mainly adopt chips of ATMEL series as follows:
Technical specification: AT24C01: 1k bit AT24C02: 2k bit AT24C04: 4k bit AT24C08: 8k bit AAT24C16: 16k bit AT24C64: 64k bit Operating frequency: 1MHz(5V) 1ZHz(2.7V) 400KHz(1.8V) Operating voltage: 5V10%, min 1.8V if required ICC current: Read: max 1MA Write: max 3MA Operating temperature: 0-70, Exceed this range if required Write\\erase: 1,000,000 Data retention: 100yares ESD protection: 4000V Application area: Data storage, phone card, campus card and so on.
