CAT25C08

Not Recommended for New Design, Replace with CAT25080/CAT25160 CAT25C08, CAT25C16 8K/16K SPI Serial CMOS EEPROM FEATURES I 10 MHz SPI compatible I 1.8 to 5.5 volt operation I SPI modes (0,0 & 1,1) I 32-byte page write buffer I Self-timed write cycle I Hardware and software protection I Block write protection DESCRIPTION The CAT25C08/16 is a 8K/16K Bit SPI Serial CMOS EEPROM internally organized as 1024x8/2048x8 bits. Catalyst’s advanced CMOS Technology substantially reduces device power requirements. The CAT25C08/ 16 features a 32-byte page write buffer. The device operates via the SPI bus serial interface and is enabled though a Chip Select (CS). In addition to the Chip Select, the clock input (SCK), data in (SI) and data out (SO) are required to access the device. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence. The CAT25C08/16 is designed with software and hardware write protection features including Block Write protection. The device is available in 8-pin DIP, 8-pin SOIC and 8-pin TSSOP packages. – Protect 1/4, 1/2 or all of EEPROM array I Low power CMOS technology I 1,000,000 program/erase cycles I 100 year data retention I Industrial temperature range I RoHS-compliant packages For Ordering Information details, see page 15.
