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 PIN CONFIGURATION CS SO WP VSS MSOP Package (R, Z, GZ)- SOIC Package (S, V, GV) 1 2 3 4 8 7 6 5 HOLD SCK SI - CAT25C11/03 only PIN FUNCTIONS Pin Name SO SCK WP VCC VSS CS SI i D c s Ground Function Serial Data Output i t n o CS SO WP VSS 1 2 3 4 8 7 6 5 VCC .. HOLD SCK SI u n CS SO WP VSS 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 munication 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. d e 8 7 6 5 VCC HOLD SCK SI a P CS SO WP VSS 1 2 3 4 s t r 8 7 6 5 VCC HOLD SCK SI DIP Package (P, L, GL) 1 2 3 4 TSSOP Package (U, Y, GY) BLOCK DIAGRAM SENSE AMPS SHIFT REGISTERS WORD ADDRESS...
