Description

The CAT25256XI is a 256−Kb Serial CMOS EEPROM device internally organized as 32Kx8 bits. This features a 64−byte page write buffer and supports the Serial Peripheral Interface (SPI) protocol. The device is enabled through a Chip Select (CS) input. In addition, therequired bus signals are clock input (SCK), data input (SI) and data output (SO) lines. The HOLD input may be used to pause any serial communication with the CAT25256XI device. The device features software and hardware write protection, including partial as well as full array protection. CAT25256XI Features • 10 MHz SPI Compatible• 1.8 V to 5.5 V Supply Voltage Range• SPI Modes (0,0) & (1,1)• 64−byte Page Write Buffer• Self−timed Write Cycle• Hardware and Software Protection• Block Write Protection− Protect 1/4, 1/2 or Entire EEPROM Array• Low Power CMOS Technology• 1,000,000 Program/Erase Cycles• 100 Year Data Retention• Industrial and Extended Temperature Range• 8−lead PDIP, SOIC, TSSOP and 8−pad TDFN Packages• 8−ball Chip Scale Package (CSP)• This Device is Pb−Free, Halogen Free/BFR Free, and RoHS Compliant
