Characteristics subject to change without notice DESCRIPTION The CAT25C11/03/05/09/17 is a 1K/2K/4K/8K/16K-Bit SPI Serial CMOS EEPROM internally organized as 128x8/256x8/512x8/1024x8/2048x8 bits. Catalyst’s advanced CMOS Technology substantially reduces device power requirements. The CAT25C11/03/05 features a 16-byte page write buffer. The 25C09/17 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 CAT25C11/03/05/09/17 is designed with software and hardware write protection features including Block Write protection. The device is available in 8-pin DIP, 8-pin SOIC, 8/14-pin TSSOP and 8-pin MSOP packages.
