CAT35C904

The CAT35C904 is a 4k-bit,RF version of the secure access serial EEPROM devices,and a member of CATALYST semiconductors proprietary family of intelligent memories.With this configuration,the user now has a monolithic solution to contact-less serial communication.Communication and power requirements for operation are derived from a received sinusoldal signal in the 100 to 500 KHz range.On-chip regulation and rectification of the incoming transmission provides the power necessary for operation,including the high voltages required for EEPROM programming.

Features of the CAT25C64S are:(1)contactless serial communication; (2)on-chip power generation; (3)password READ/WRITE-protect ; (4)non-password write-protect ; (5)sequential data register READ; (6)user definable protected area; (7)password length:1 to 8 bytes; (8)data format:*8 or *16; (9)low power consumption; (10)10 year data retention; (11)10,000 write/erase cycles.

The absolute maximum ratings of the CAT25C64S can be summarized as:(1)operating supply current:65A; (2)outpu voltage:4.99; (3)line regulation:0.1%(dc);20%(300KHz); (4)reference voltage:2.53V; (5)temperature coefficent:200 ppm/C(before bandgap trim);30 ppm/C(after bandgap trim).If you want to know more information such as the electrical characteristics, please download the datasheet in www.seekic.com or www.chinaicmart.com.
